When the player gives an answer, I must make a comparison between the answer they give, and the correct answer, to decide whether or not they score a point.

This is far from the end of the story though. We previous defined a function to be a command that takes an input argument, and returns an output. The real power of functions, however, is that we can create our own, making a piece of code that can be reused anywhere in our program, or imported into other programs.\n", - "\n", - "Remember, the key to programming is breaking down large complex tasks into small simple tasks. Functions are the key to doing this. They help us to organize and formalize this process by turning each small task into a separate function. These functions can then be reused and combined over and over. For this reason, you should virtually never have to copy and paste code to complete several similar tasks: the correct thing to do is create a function that completes these tasks, and use it several times.\n", - "\n", - "This leads to the concept computer scientists refer to as \"abstraction\". It means that already-solved problems can be essentially forgotten about, treated as single step in an algorithm, however complex that problem may have been initially. For example, if I am building a program that collects stock market data from the web, the simple act of making a webpage request is extraordinarily complex. My request travels in the form of electrical \"on/off\" (0/1) signals through the air to my home router, a computer which reads the metadata of my request and sends the request on a journey via dozens of other routers; to a server with the software to decode my 0s and 1s; which then gets the stock market data by some other magic; and then sends the data back to my computer's address, again via dozens of routers, each one figuring where to send the information next; finally decoded my home computer. The process is extremely complex. But it was solved by the original engineers of the internet and the hyper-text transfer protocol (HTTP) decades ago. To me, in my project, I just run pandas' web data reader function. It's all achieved in a single step. That is abstraction in a nutshell. Functions allow us to solve a complicated problem once, and then treat it as a single step thereafter.\n", - "\n", - "Once again, functions in the code are indicated by a header, followed by the correct indentation.

This is where we use a mouse or touch screen to press on-screen buttons, drag-and-drop files, highlight text, move a scroll bar, or bring up a menu.

A command-line is any computer interface in which you type text commands rather than click buttons to make things happen. A terminal or terminal emulator is a piece of software on your computer that displays the text for a command-line interface. Finally, a shell is the software \"behind the scenes\", that interprets your commands, performs the tasks you ask of it, and then displays the result in your terminal. These words are sometimes used somewhat interchangeably.

If you are on Windows, but either you do not have Windows 10 or you do not want to install Bash for some reason, then you can use a software that comes with Windows call Powershell.

A character is the abstract meaning behind the little squiggles you see on the screen that form text. The squiggles themselves are called \"glyphs\". However, the glyphs cannot be the characters, since in different fonts, the same character can be represented by two very different glyphs. So for instance, the character that is \"the first uppercase letter of the latin alphabet and sounds like 'ey'\" is represented by the glyph \"A\".

This means that lots of different character encodings sprang up -- methods for turning the bytes (numbers) in a file into text on the screen. In the UK and US, the common solution was ASCII encoding, which due to our relatively small alphabet meant that each character could be stored in a single byte as a number between 0 and 127.\n", - "\n", - "These days, there is something called the internet, which means that text is now flying all over the world, from the US, which uses only a few characters; to Europe, which uses more because of all the accents; to Greece, Russia, and Middle East, which have different alphabets; to China, which has literally thousands of characters.

In a nutshell, each character is assigned to a unicode \"code point\", usually written in . For instance the letter \"A\" is \"0041\". This is not an encoding, but merely an organization method. At least now we can organize the characters of the world into some kind of coherent structure, a bit like a periodic table of elements but for text. According to Wikipedia, the current version of unicode contains 136,755 characters from 139 writing systems, plus additional symbols that are not from any particular writing system, such as emoji. When you create a string in Python, it is considered to be a sequence of unicode code points.\n", - "\n", - "Note that unicode code points are generally given in hexadecimal. This is simply a way of writing down numbers using 16 symbols instead of the usual ten (or two, in binary), meaning larger numbers can be written using fewer digits. Since we have only ten numerals, letters are used instead; the numerals used in hexadecimal are 0123456789ABCDEF. E is fourteen, F is fifteen. 10 is sixteen, 11 is seventeen, all the way to FF, which is 255 in decimal, and then we start again with 100. This is just a way to shorten long numbers in binary -- each hex digit corresponds to 4 binary digits (bits), meaning that a byte is represented by two hex digits. There's rarely any need to do arithmetic with hex-reperesented numbers, or figure out what the decimal/binary representation is. Just be aware that when you see, say, \"A3\" when discussing a unicode code point, it is actually a number.\n", - "\n", - "There remains the question then of how to encode these characters into bytes. Unicode has several possible standards. The reason for different standards is that European computer users, say, whose languages' characters could be stored in 2 bytes, did not want to have to use additional bytes to store all the Chinese characters they seldom used, for example by allocating 4 bytes per character. By having different encoding systems, we've solved one problem, but it's very not flexible. What about times when we need those occasional Chinese characters? What about emoji?\n", - "\n", - "Then two bright sparks, Ken Thompson and Rob Pike, came up with a new encoding system called UTF-8. In their system the number of bytes per character could vary. The standard ASCII characters, for example, could be stored as 1 byte. Accented characters, 2 bytes. 3 bytes is enough to store all the Chinese characters. Other, uncommon symbols, such as emoji, are relegated to taking up 4 bytes. And all of these can co-exist within the same file. There's no need to switch encoding midway through. In theory, it \"just works\".\n", - "\n", - "There is a price to pay, as with most nice things in life. For a program to search through UTF-8 encoded text now takes longer, because it can't count on each of the characters being the same length (in terms of digits); it has to check each byte separately to see when one character ends and the next begins.\n", - "\n", - "Nonetheless, UTF-8 is now the standard encoding on the web, accounting for 90% of websites.

Firstly, observe that at first, Python does not know what \"next\" means in terms of a string:" - ] - }, - { - "cell_type": "code", - "execution_count": 54, - "metadata": {}, - "outputs": [ - { - "ename": "TypeError", - "evalue": "'str' object is not an iterator", - "output_type": "error", - "traceback": [ - "\u001b[1;31m---------------------------------------------------------------------------\u001b[0m", - "\u001b[1;31mTypeError\u001b[0m Traceback (most recent call last)", - "\u001b[1;32m\u001b[0m in \u001b[0;36m\u001b[1;34m()\u001b[0m\n\u001b[0;32m 1\u001b[0m \u001b[0mpythonclub\u001b[0m \u001b[1;33m=\u001b[0m \u001b[1;34m\"HiPy\"\u001b[0m\u001b[1;33m\u001b[0m\u001b[0m\n\u001b[1;32m----> 2\u001b[1;33m \u001b[0mnext\u001b[0m\u001b[1;33m(\u001b[0m\u001b[0mpythonclub\u001b[0m\u001b[1;33m)\u001b[0m\u001b[1;33m\u001b[0m\u001b[0m\n\u001b[0m", - "\u001b[1;31mTypeError\u001b[0m: 'str' object is not an iterator" - ] - } - ], - "source": [ - "pythonclub = \"HiPy\"\n", - "print(next(pythonclub))" - ] - }, - { - "cell_type": "markdown", - "metadata": {}, - "source": [ - "However, we can ask the string to give us an iterator:" - ] - }, - { - "cell_type": "code", - "execution_count": 55, - "metadata": { - "collapsed": true - }, - "outputs": [], - "source": [ - "iterclub = iter(pythonclub)" - ] - }, - { - "cell_type": "markdown", - "metadata": {}, - "source": [ - "Now we can ask for the next value:" - ] - }, - { - "cell_type": "code", - "execution_count": 56, - "metadata": {}, - "outputs": [ - { - "name": "stdout", - "output_type": "stream", - "text": [ - "H\n" - ] - } - ], - "source": [ - "print(next(iterclub))" - ] - }, - { - "cell_type": "code", - "execution_count": 57, - "metadata": {}, - "outputs": [ - { - "name": "stdout", - "output_type": "stream", - "text": [ - "i\n" - ] - } - ], - "source": [ - "print(next(iterclub))" - ] - }, - { - "cell_type": "code", - "execution_count": 58, - "metadata": {}, - "outputs": [ - { - "name": "stdout", - "output_type": "stream", - "text": [ - "P\n" - ] - } - ], - "source": [ - "print(next(iterclub))" - ] - }, - { - "cell_type": "code", - "execution_count": 59, - "metadata": {}, - "outputs": [ - { - "name": "stdout", - "output_type": "stream", - "text": [ - "y\n" - ] - } - ], - "source": [ - "print(next(iterclub))" - ] - }, - { - "cell_type": "code", - "execution_count": 60, - "metadata": {}, - "outputs": [ - { - "ename": "StopIteration", - "evalue": "", - "output_type": "error", - "traceback": [ - "\u001b[1;31m---------------------------------------------------------------------------\u001b[0m", - "\u001b[1;31mStopIteration\u001b[0m Traceback (most recent call last)", - "\u001b[1;32m\u001b[0m in \u001b[0;36m\u001b[1;34m()\u001b[0m\n\u001b[1;32m----> 1\u001b[1;33m \u001b[0mprint\u001b[0m\u001b[1;33m(\u001b[0m\u001b[0mnext\u001b[0m\u001b[1;33m(\u001b[0m\u001b[0miterclub\u001b[0m\u001b[1;33m)\u001b[0m\u001b[1;33m)\u001b[0m\u001b[1;33m\u001b[0m\u001b[0m\n\u001b[0m", - "\u001b[1;31mStopIteration\u001b[0m: " - ] - } - ], - "source": [ - "print(next(iterclub)) # we're out of letters!" - ] - }, - { - "cell_type": "markdown", - "metadata": {}, - "source": [ - "So what a for-loop does is ask the object (string, list, range, etc) we provide for an iterator, and then use next on the object until it runs out.\n", - "\n", - "We'll discuss this point in more detail when we discuss object-oriented programming.

introduce the very basic concept of functional programming, as something to chew over and consider in your own program designs. So far, what we have been doing is what is called imperative programming. The program has a state, which means it holds some things in memory, usually in the form of variables, and we proceed by updating the program's state by changing these variables, reassigning them, and so on. At the top of this article, we used recursion to find the $n$th fibonacci number. Let's now do it in a pure imperative style:" - ] - }, - { - "cell_type": "code", - "execution_count": 69, - "metadata": {}, - "outputs": [ - { - "name": "stdout", - "output_type": "stream", - "text": [ - "514229\n" - ] - } - ], - "source": [ - "n = 30\n", - "for k in range(n):\n", - " if k < 2:\n", - " x = 0\n", - " y = 1\n", - " else:\n", - " # to understand this line, remember that when assigning variables\n", - " # the right hand side is fully evaulated before being assigned to the LHS\n", - " x, y = y, x + y\n", - "print(y)\n", - " " - ] - }, - { - "cell_type": "markdown", - "metadata": {}, - "source": [ - "This program achieves the same task, but we first set n to something. Then we iterate over k, and for each k, update two variables x and y. At each pass through the loop, the state of the program is changed; k, x, and y are all modified\\*. That is imperative programming in a nutshell." - ] - }, - { - "cell_type": "markdown", - "metadata": {}, - "source": [ - "While imperative programming is easy to get going with, it's also easy to get in a tangle with. Because different functions are constantly referring to and altering different parts of a (large) program's state, it's very easy for errors to occur because some part of the program's state is wrong at the time a particular function or operation is executed.\n", - "\n", - "Functional programming aims to fix this by encouraging a very different style of design. Functional programming demands that we make our functions behave like mathematical functions, in that there is one, and only one, possible output for each input to a function. In imperative programming, the function may behave differently at different times with the same inputs, because the program's state is different at those different times. Moreover, the function may alter the program's state, which can cause other functions to behave differently at a later time. This is the concept of \"side-effects\".\n", - "\n", - "In functional programming, the program does not have a state. It has functions, which behave in exactly the same way every time they are called with the same inputs, guaranteed. Each function has an input, and an output, and nothing that goes on inbetween can have any effect on, or be affected by, the rest of the program's behaviour. Check out the recursive fibonacci program; there's not a variable in sight. Just functions taking inputs and returning values. This leads to essentially bug-free code, so long as the functions are correctly defined and applied in the correct order. \n", - "\n", - "Functional programming isn't easy, but Python does have some support to make it easier via the functools module. While some programming languages are purely functional, Python is multi-paradigm, and the good thing about functional programming in Python is it needn't be all or nothing. It can fit around the rest of your program design. After all, the whole point of functional programming is \"no side effects\"! Thus if you find that you can solve one of your problems by writing a function that neither affects nor is affected by the program's state, but only by its input values, then why not go ahead and do it that way, reaping some of the benefits of functional programming as you do?\n", - "\n", - "For some specific examples of functional programming techniques in Python, see this article https://maryrosecook.com/blog/post/a-practical-introduction-to-functional-programming\n", - "Note that the examples are in Python 2, which means print() does not need the brackets. Also, the author uses map(), filter a lot; in Python 3 it is generally considered preferable to use list comprehensions to perform the same task.\n", - "\n", - "\\* This is a subtle point about for-loops easily missed. The variable that gets bound at the start of each pass through, such as the x appearing in the line for x in range(10), remains assigned even after the loop is finished running. Therefore, as far as functional programming goes, it constitutes a side-effect -- the state of the program is changed. The same is not true of the \"for loops\" found in list comprehensions; these are side-effect free." - ] - }, - { - "cell_type": "code", - "execution_count": null, - "metadata": { - "collapsed": true - }, - "outputs": [], - "source": [] - } - ], - "metadata": { - "kernelspec": { - "display_name": "Python 3", - "language": "python", - "name": "python3" - }, - "language_info": { - "codemirror_mode": { - "name": "ipython", - "version": 3 - }, - "file_extension": ".py", - "mimetype": "text/x-python", - "name": "python", - "nbconvert_exporter": "python", - "pygments_lexer": "ipython3", - "version": "3.6.1" - } - }, - "nbformat": 4, - "nbformat_minor": 1 -} diff --git a/[BASICS] Getting Started With Python 1 - The Basics/.ipynb_checkpoints/Getting Started In Python 1 - The Basics-checkpoint.ipynb b/[BASICS] Getting Started With Python 1 - The Basics/.ipynb_checkpoints/Getting Started In Python 1 - The Basics-checkpoint.ipynb deleted file mode 100644 index b88f08c..0000000 --- a/[BASICS] Getting Started With Python 1 - The Basics/.ipynb_checkpoints/Getting Started In Python 1 - The Basics-checkpoint.ipynb +++ /dev/null @@ -1,618 +0,0 @@ -{ - "cells": [ - { - "cell_type": "markdown", - "metadata": {}, - "source": [ - "![title](banner.png)" - ] - }, - { - "cell_type": "markdown", - "metadata": {}, - "source": [ - "Congratulations on getting set up with Python!

The return value will -be an abstract syntax tree object as specified by the -[ESTree spec][estree]. - -When encountering a syntax error, the parser will raise a -`SyntaxError` object with a meaningful message. The error object will -have a `pos` property that indicates the character offset at which the -error occurred, and a `loc` object that contains a `{line, column}` -object referring to that same position. - -[estree]: https://github.com/estree/estree - -- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be - either 3, 5, or 6. This influences support for strict mode, the set - of reserved words, and support for new syntax features. Default is 5. - -- **sourceType**: Indicate the mode the code should be parsed in. Can be - either `"script"` or `"module"`. - -- **onInsertedSemicolon**: If given a callback, that callback will be - called whenever a missing semicolon is inserted by the parser. The - callback will be given the character offset of the point where the - semicolon is inserted as argument, and if `locations` is on, also a - `{line, column}` object representing this position. - -- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing - commas. - -- **allowReserved**: If `false`, using a reserved word will generate - an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher - versions. When given the value `"never"`, reserved words and - keywords can also not be used as property names (as in Internet - Explorer's old parser). - -- **allowReturnOutsideFunction**: By default, a return statement at - the top level raises an error. Set this to `true` to accept such - code. - -- **allowImportExportEverywhere**: By default, `import` and `export` - declarations can only appear at a program's top level. Setting this - option to `true` allows them anywhere where a statement is allowed. - -- **allowHashBang**: When this is enabled (off by default), if the - code starts with the characters `#!` (as in a shellscript), the - first line will be treated as a comment. - -- **locations**: When `true`, each node has a `loc` object attached - with `start` and `end` subobjects, each of which contains the - one-based line and zero-based column numbers in `{line, column}` - form. Default is `false`. - -- **onToken**: If a function is passed for this option, each found - token will be passed in same format as tokens returned from - `tokenizer().getToken()`. - - If array is passed, each found token is pushed to it. - - Note that you are not allowed to call the parser from the - callback—that will corrupt its internal state. - -- **onComment**: If a function is passed for this option, whenever a - comment is encountered the function will be called with the - following parameters: - - - `block`: `true` if the comment is a block comment, false if it - is a line comment. - - `text`: The content of the comment. - - `start`: Character offset of the start of the comment. - - `end`: Character offset of the end of the comment. - - When the `locations` options is on, the `{line, column}` locations - of the comment’s start and end are passed as two additional - parameters. - - If array is passed for this option, each found comment is pushed - to it as object in Esprima format: - - ```javascript - { - "type": "Line" | "Block", - "value": "comment text", - "start": Number, - "end": Number, - // If `locations` option is on: - "loc": { - "start": {line: Number, column: Number} - "end": {line: Number, column: Number} - }, - // If `ranges` option is on: - "range": [Number, Number] - } - ``` - - Note that you are not allowed to call the parser from the - callback—that will corrupt its internal state. - -- **ranges**: Nodes have their start and end characters offsets - recorded in `start` and `end` properties (directly on the node, - rather than the `loc` object, which holds line/column data. To also - add a [semi-standardized][range] `range` property holding a - `[start, end]` array with the same numbers, set the `ranges` option - to `true`. - -- **program**: It is possible to parse multiple files into a single - AST by passing the tree produced by parsing the first file as the - `program` option in subsequent parses. This will add the toplevel - forms of the parsed file to the "Program" (top) node of an existing - parse tree. - -- **sourceFile**: When the `locations` option is `true`, you can pass - this option to add a `source` attribute in every node’s `loc` - object. Note that the contents of this option are not examined or - processed in any way; you are free to use whatever format you - choose. - -- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property - will be added directly to the nodes, rather than the `loc` object. - -- **preserveParens**: If this option is `true`, parenthesized expressions - are represented by (non-standard) `ParenthesizedExpression` nodes - that have a single `expression` property containing the expression - inside parentheses. - -[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678 - -**parseExpressionAt**`(input, offset, options)` will parse a single -expression in a string, and return its AST. It will not complain if -there is more of the string left after the expression. - -**getLineInfo**`(input, offset)` can be used to get a `{line, -column}` object for a given program string and character offset. - -**tokenizer**`(input, options)` returns an object with a `getToken` -method that can be called repeatedly to get the next token, a `{start, -end, type, value}` object (with added `loc` property when the -`locations` option is enabled and `range` property when the `ranges` -option is enabled). When the token's type is `tokTypes.eof`, you -should stop calling the method, since it will keep returning that same -token forever. - -In ES6 environment, returned result can be used as any other -protocol-compliant iterable: - -```javascript -for (let token of acorn.tokenizer(str)) { - // iterate over the tokens -} - -// transform code to array of tokens: -var tokens = [...acorn.tokenizer(str)]; -``` - -**tokTypes** holds an object mapping names to the token type objects -that end up in the `type` properties of tokens. - -#### Note on using with [Escodegen][escodegen] - -Escodegen supports generating comments from AST, attached in -Esprima-specific format. In order to simulate same format in -Acorn, consider following example: - -```javascript -var comments = [], tokens = []; - -var ast = acorn.parse('var x = 42; // answer', { - // collect ranges for each node - ranges: true, - // collect comments in Esprima's format - onComment: comments, - // collect token ranges - onToken: tokens -}); - -// attach comments using collected information -escodegen.attachComments(ast, comments, tokens); - -// generate code -console.log(escodegen.generate(ast, {comment: true})); -// > 'var x = 42; // answer' -``` - -[escodegen]: https://github.com/estools/escodegen - -### dist/acorn_loose.js ### - -This file implements an error-tolerant parser. It exposes a single -function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`. - -**parse_dammit**`(input, options)` takes the same arguments and -returns the same syntax tree as the `parse` function in `acorn.js`, -but never raises an error, and will do its best to parse syntactically -invalid code in as meaningful a way as it can. It'll insert identifier -nodes with name `"✖"` as placeholders in places where it can't make -sense of the input. Depends on `acorn.js`, because it uses the same -tokenizer. - -### dist/walk.js ### - -Implements an abstract syntax tree walker. Will store its interface in -`acorn.walk` when loaded without a module system. - -**simple**`(node, visitors, base, state)` does a 'simple' walk over -a tree. `node` should be the AST node to walk, and `visitors` an -object with properties whose names correspond to node types in the -[ESTree spec][estree]. The properties should contain functions -that will be called with the node object and, if applicable the state -at that point. The last two arguments are optional. `base` is a walker -algorithm, and `state` is a start state. The default walker will -simply visit all statements and expressions and not produce a -meaningful state. (An example of a use of state is to track scope at -each point in the tree.) - -**ancestor**`(node, visitors, base, state)` does a 'simple' walk over -a tree, building up an array of ancestor nodes (including the current node) -and passing the array to callbacks in the `state` parameter. - -**recursive**`(node, state, functions, base)` does a 'recursive' -walk, where the walker functions are responsible for continuing the -walk on the child nodes of their target node. `state` is the start -state, and `functions` should contain an object that maps node types -to walker functions. Such functions are called with `(node, state, c)` -arguments, and can cause the walk to continue on a sub-node by calling -the `c` argument on it with `(node, state)` arguments. The optional -`base` argument provides the fallback walker functions for node types -that aren't handled in the `functions` object. If not given, the -default walkers will be used. - -**make**`(functions, base)` builds a new walker object by using the -walker functions in `functions` and filling in the missing ones by -taking defaults from `base`. - -**findNodeAt**`(node, start, end, test, base, state)` tries to -locate a node in a tree at the given start and/or end offsets, which -satisfies the predicate `test`. `start` and `end` can be either `null` -(as wildcard) or a number. `test` may be a string (indicating a node -type) or a function that takes `(nodeType, node)` arguments and -returns a boolean indicating whether this node is interesting. `base` -and `state` are optional, and can be used to specify a custom walker. -Nodes are tested from inner to outer, so if two nodes match the -boundaries, the inner one will be preferred. - -**findNodeAround**`(node, pos, test, base, state)` is a lot like -`findNodeAt`, but will match any node that exists 'around' (spanning) -the given position. - -**findNodeAfter**`(node, pos, test, base, state)` is similar to -`findNodeAround`, but will match all nodes *after* the given position -(testing outer nodes before inner nodes). - -## Command line interface - -The `bin/acorn` utility can be used to parse a file from the command -line. It accepts as arguments its input file and the following -options: - -- `--ecma3|--ecma5|--ecma6`: Sets the ECMAScript version to parse. Default is - version 5. - -- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise. - -- `--locations`: Attaches a "loc" object to each node with "start" and - "end" subobjects, each of which contains the one-based line and - zero-based column numbers in `{line, column}` form. - -- `--allow-hash-bang`: If the code starts with the characters #! (as in a shellscript), the first line will be treated as a comment. - -- `--compact`: No whitespace is used in the AST output. - -- `--silent`: Do not output the AST, just return the exit status. - -- `--help`: Print the usage information and quit. - -The utility spits out the syntax tree as JSON data. - -## Build system - -Acorn is written in ECMAScript 6, as a set of small modules, in the -project's `src` directory, and compiled down to bigger ECMAScript 3 -files in `dist` using [Browserify](http://browserify.org) and -[Babel](http://babeljs.io/). If you are already using Babel, you can -consider including the modules directly. - -The command-line test runner (`npm test`) uses the ES6 modules. The -browser-based test page (`test/index.html`) uses the compiled modules. -The `bin/build-acorn.js` script builds the latter from the former. - -If you are working on Acorn, you'll probably want to try the code out -directly, without an intermediate build step. In your scripts, you can -register the Babel require shim like this: - - require("babel-core/register") - -That will allow you to directly `require` the ES6 modules. - -## Plugins - -Acorn is designed support allow plugins which, within reasonable -bounds, redefine the way the parser works. Plugins can add new token -types and new tokenizer contexts (if necessary), and extend methods in -the parser object. This is not a clean, elegant API—using it requires -an understanding of Acorn's internals, and plugins are likely to break -whenever those internals are significantly changed. But still, it is -_possible_, in this way, to create parsers for JavaScript dialects -without forking all of Acorn. And in principle it is even possible to -combine such plugins, so that if you have, for example, a plugin for -parsing types and a plugin for parsing JSX-style XML literals, you -could load them both and parse code with both JSX tags and types. - -A plugin should register itself by adding a property to -`acorn.plugins`, which holds a function. Calling `acorn.parse`, a -`plugins` option can be passed, holding an object mapping plugin names -to configuration values (or just `true` for plugins that don't take -options). After the parser object has been created, the initialization -functions for the chosen plugins are called with `(parser, -configValue)` arguments. They are expected to use the `parser.extend` -method to extend parser methods. For example, the `readToken` method -could be extended like this: - -```javascript -parser.extend("readToken", function(nextMethod) { - return function(code) { - console.log("Reading a token!") - return nextMethod.call(this, code) - } -}) -``` - -The `nextMethod` argument passed to `extend`'s second argument is the -previous value of this method, and should usually be called through to -whenever the extended method does not handle the call itself. - -Similarly, the loose parser allows plugins to register themselves via -`acorn.pluginsLoose`. The extension mechanism is the same as for the -normal parser: - -```javascript -looseParser.extend("readToken", function(nextMethod) { - return function() { - console.log("Reading a token in the loose parser!") - return nextMethod.call(this) - } -}) -``` - -There is a proof-of-concept JSX plugin in the [`acorn-jsx`](https://github.com/RReverser/acorn-jsx) project. diff --git a/web/node_modules/acorn/bin/acorn b/web/node_modules/acorn/bin/acorn deleted file mode 100755 index db07909..0000000 --- a/web/node_modules/acorn/bin/acorn +++ /dev/null @@ -1,71 +0,0 @@ -#!/usr/bin/env node -"use strict"; - -function _interopRequireWildcard(obj) { if (obj && obj.__esModule) { return obj; } else { var newObj = {}; if (obj != null) { for (var key in obj) { if (Object.prototype.hasOwnProperty.call(obj, key)) newObj[key] = obj[key]; } } newObj["default"] = obj; return newObj; } } - -var _path = require("path"); - -var _fs = require("fs"); - -var _distAcornJs = require("../dist/acorn.js"); - -var acorn = _interopRequireWildcard(_distAcornJs); - -var infile = undefined, - forceFile = undefined, - silent = false, - compact = false, - tokenize = false; -var options = {}; - -function help(status) { - var print = status == 0 ?

If jQuery is not available, `angular.element`\n * delegates to Angular's built-in subset of jQuery, called \"jQuery lite\" or \"jqLite.\"\n *\n *
jqLite is a tiny, API-compatible subset of jQuery that allows\n * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most\n * commonly needed functionality with the goal of having a very small footprint.
\n *\n * To use jQuery, simply load it before `DOMContentLoaded` event fired.\n *\n *
**Note:** all element references in Angular are always wrapped with jQuery or\n * jqLite; they are never raw DOM references.
\n *\n * ## Angular's jqLite\n * jqLite provides only the following jQuery methods:\n *\n * - [`addClass()`](http://api.jquery.com/addClass/)\n * - [`after()`](http://api.jquery.com/after/)\n * - [`append()`](http://api.jquery.com/append/)\n * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters\n * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData\n * - [`children()`](http://api.jquery.com/children/) - Does not support selectors\n * - [`clone()`](http://api.jquery.com/clone/)\n * - [`contents()`](http://api.jquery.com/contents/)\n * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`\n * - [`data()`](http://api.jquery.com/data/)\n * - [`detach()`](http://api.jquery.com/detach/)\n * - [`empty()`](http://api.jquery.com/empty/)\n * - [`eq()`](http://api.jquery.com/eq/)\n * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name\n * - [`hasClass()`](http://api.jquery.com/hasClass/)\n * - [`html()`](http://api.jquery.com/html/)\n * - [`next()`](http://api.jquery.com/next/) - Does not support selectors\n * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData\n * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors\n * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors\n * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors\n * - [`prepend()`](http://api.jquery.com/prepend/)\n * - [`prop()`](http://api.jquery.com/prop/)\n * - [`ready()`](http://api.jquery.com/ready/)\n * - [`remove()`](http://api.jquery.com/remove/)\n * - [`removeAttr()`](http://api.jquery.com/removeAttr/)\n * - [`removeClass()`](http://api.jquery.com/removeClass/)\n * - [`removeData()`](http://api.jquery.com/removeData/)\n * - [`replaceWith()`](http://api.jquery.com/replaceWith/)\n * - [`text()`](http://api.jquery.com/text/)\n * - [`toggleClass()`](http://api.jquery.com/toggleClass/)\n * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.\n * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces\n * - [`val()`](http://api.jquery.com/val/)\n * - [`wrap()`](http://api.jquery.com/wrap/)\n *\n * ## jQuery/jqLite Extras\n * Angular also provides the following additional methods and events to both jQuery and jqLite:\n *\n * ### Events\n * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event\n * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM\n * element before it is removed.\n *\n * ### Methods\n * - `controller(name)` - retrieves the controller of the current element or its parent. By default\n * retrieves controller associated with the `ngController` directive. If `name` is provided as\n * camelCase directive name, then the controller for this directive will be retrieved (e.g.\n * `'ngModel'`).\n * - `injector()` - retrieves the injector of the current element or its parent.\n * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current\n * element or its parent.

\n * **Note:** This document is an in-depth reference of all directive options.\n * For a gentle introduction to directives with examples of common use cases,\n * see the {@link guide/directive directive guide}.\n *
\n *\n * ## Comprehensive Directive API\n *\n * There are many different options for a directive.\n *\n * The difference resides in the return value of the factory function.\n * You can either return a \"Directive Definition Object\" (see below) that defines the directive properties,\n * or just the `postLink` function (all other properties will have the default values).\n *\n *
\n * **Best Practice:** It's recommended to use the \"directive definition object\" form.\n *
\n *\n * Here's an example directive declared with a Directive Definition Object:\n *\n * ```js\n * var myModule = angular.module(...);\n *\n * myModule.directive('directiveName', function factory(injectables) {\n * var directiveDefinitionObject = {\n * priority: 0,\n * template: '
', // or // function(tElement, tAttrs) { ... },\n * // or\n * // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },\n * transclude: false,\n * restrict: 'A',\n * templateNamespace: 'html',\n * scope: false,\n * controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },\n * controllerAs: 'stringAlias',\n * require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],\n * compile: function compile(tElement, tAttrs, transclude) {\n * return {\n * pre: function preLink(scope, iElement, iAttrs, controller) { ... },\n * post: function postLink(scope, iElement, iAttrs, controller) { ... }\n * }\n * // or\n * // return function postLink( ... ) { ... }\n * },\n * // or\n * // link: {\n * // pre: function preLink(scope, iElement, iAttrs, controller) { ... },\n * // post: function postLink(scope, iElement, iAttrs, controller) { ... }\n * // }\n * // or\n * // link: function postLink( ... ) { ... }\n * };\n * return directiveDefinitionObject;\n * });\n * ```\n *\n *
\n * **Note:** Any unspecified options will use the default value. You can see the default values below.\n *
\n *\n * Therefore the above can be simplified as:\n *\n * ```js\n * var myModule = angular.module(...);\n *\n * myModule.directive('directiveName', function factory(injectables) {\n * var directiveDefinitionObject = {\n * link: function postLink(scope, iElement, iAttrs) { ... }\n * };\n * return directiveDefinitionObject;\n * // or\n * // return function postLink(scope, iElement, iAttrs) { ... }\n * });\n * ```\n *\n *\n *\n * ### Directive Definition Object\n *\n * The directive definition object provides instructions to the {@link ng.$compile\n * compiler}. The attributes are:\n *\n * #### `multiElement`\n * When this property is set to true, the HTML compiler will collect DOM nodes between\n * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them\n * together as the directive elements. It is recommended that this feature be used on directives\n * which are not strictly behavioural (such as {@link ngClick}), and which\n * do not manipulate or replace child nodes (such as {@link ngInclude}).\n *\n * #### `priority`\n * When there are multiple directives defined on a single DOM element, sometimes it\n * is necessary to specify the order in which the directives are applied. The `priority` is used\n * to sort the directives before their `compile` functions get called. Priority is defined as a\n * number. Directives with greater numerical `priority` are compiled first. Pre-link functions\n * are also run in priority order, but post-link functions are run in reverse order. The order\n * of directives with the same priority is undefined. The default priority is `0`.\n *\n * #### `terminal`\n * If set to true then the current `priority` will be the last set of directives\n * which will execute (any directives at the current priority will still execute\n * as the order of execution on same `priority` is undefined). Note that expressions\n * and other directives used in the directive's template will also be excluded from execution.\n *\n * #### `scope`\n * **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the\n * same element request a new scope, only one new scope is created. The new scope rule does not\n * apply for the root of the template since the root of the template always gets a new scope.\n *\n * **If set to `{}` (object hash),** then a new \"isolate\" scope is created. The 'isolate' scope differs from\n * normal scope in that it does not prototypically inherit from the parent scope. This is useful\n * when creating reusable components, which should not accidentally read or modify data in the\n * parent scope.\n *\n * The 'isolate' scope takes an object hash which defines a set of local scope properties\n * derived from the parent scope. These local properties are useful for aliasing values for\n * templates. Locals definition is a hash of local scope property to its source:\n *\n * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is\n * always a string since DOM attributes are strings. If no `attr` name is specified then the\n * attribute name is assumed to be the same as the local name.\n * Given `` and widget definition\n * of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect\n * the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the\n * `localName` property on the widget scope. The `name` is read from the parent scope (not\n * component scope).\n *\n * * `=` or `=attr` - set up bi-directional binding between a local scope property and the\n * parent scope property of name defined via the value of the `attr` attribute. If no `attr`\n * name is specified then the attribute name is assumed to be the same as the local name.\n * Given `` and widget definition of\n * `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the\n * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected\n * in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent\n * scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You\n * can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. If\n * you want to shallow watch for changes (i.e. $watchCollection instead of $watch) you can use\n * `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional).\n *\n * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.\n * If no `attr` name is specified then the attribute name is assumed to be the same as the\n * local name. Given `` and widget definition of\n * `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to\n * a function wrapper for the `count = count + value` expression. Often it's desirable to\n * pass data from the isolated scope via an expression to the parent scope, this can be\n * done by passing a map of local variable names and values into the expression wrapper fn.\n * For example, if the expression is `increment(amount)` then we can specify the amount value\n * by calling the `localFn` as `localFn({amount: 22})`.\n *\n *\n * #### `bindToController`\n * When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController: true` will\n * allow a component to have its properties bound to the controller, rather than to scope. When the controller\n * is instantiated, the initial values of the isolate scope bindings are already available.\n *\n * #### `controller`\n * Controller constructor function. The controller is instantiated before the\n * pre-linking phase and it is shared with other directives (see\n * `require` attribute). This allows the directives to communicate with each other and augment\n * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:\n *\n * * `$scope` - Current scope associated with the element\n * * `$element` - Current element\n * * `$attrs` - Current attributes object for the element\n * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:\n * `function([scope], cloneLinkingFn, futureParentElement)`.\n * * `scope`: optional argument to override the scope.\n * * `cloneLinkingFn`: optional argument to create clones of the original transcluded content.\n * * `futureParentElement`:\n * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.\n * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.\n * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)\n * and when the `cloneLinkinFn` is passed,\n * as those elements need to created and cloned in a special way when they are defined outside their\n * usual containers (e.g. like ``).\n * * See also the `directive.templateNamespace` property.\n *\n *\n * #### `require`\n * Require another directive and inject its controller as the fourth argument to the linking function. The\n * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the\n * injected argument will be an array in corresponding order. If no such directive can be\n * found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with:\n *\n * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.\n * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.\n * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.\n * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.\n * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass\n * `null` to the `link` fn if not found.\n * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass\n * `null` to the `link` fn if not found.\n *\n *\n * #### `controllerAs`\n * Controller alias at the directive scope. An alias for the controller so it\n * can be referenced at the directive template. The directive needs to define a scope for this\n * configuration to be used. Useful in the case when directive is used as component.\n *\n *\n * #### `restrict`\n * String of subset of `EACM` which restricts the directive to a specific directive\n * declaration style. If omitted, the defaults (elements and attributes) are used.\n *\n * * `E` - Element name (default): ``\n * * `A` - Attribute (default): `
`\n * * `C` - Class: `
`\n * * `M` - Comment: ``\n *\n *\n * #### `templateNamespace`\n * String representing the document type used by the markup in the template.\n * AngularJS needs this information as those elements need to be created and cloned\n * in a special way when they are defined outside their usual containers like `` and ``.\n *\n * * `html` - All root nodes in the template are HTML. Root nodes may also be\n * top-level elements such as `` or ``.\n * * `svg` - The root nodes in the template are SVG elements (excluding ``).\n * * `math` - The root nodes in the template are MathML elements (excluding ``).\n *\n * If no `templateNamespace` is specified, then the namespace is considered to be `html`.\n *\n * #### `template`\n * HTML markup that may:\n * * Replace the contents of the directive's element (default).\n * * Replace the directive's element itself (if `replace` is true - DEPRECATED).\n * * Wrap the contents of the directive's element (if `transclude` is true).\n *\n * Value may be:\n *\n * * A string. For example `
{{delete_str}}
`.\n * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`\n * function api below) and returns a string value.\n *\n *\n * #### `templateUrl`\n * This is similar to `template` but the template is loaded from the specified URL, asynchronously.\n *\n * Because template loading is asynchronous the compiler will suspend compilation of directives on that element\n * for later when the template has been resolved. In the meantime it will continue to compile and link\n * sibling and parent elements as though this element had not contained any directives.\n *\n * The compiler does not suspend the entire compilation to wait for templates to be loaded because this\n * would result in the whole app \"stalling\" until all templates are loaded asynchronously - even in the\n * case when only one deeply nested directive has `templateUrl`.\n *\n * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}\n *\n * You can specify `templateUrl` as a string representing the URL or as a function which takes two\n * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns\n * a string value representing the url. In either case, the template URL is passed through {@link\n * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.\n *\n *\n * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)\n * specify what the template should replace. Defaults to `false`.\n *\n * * `true` - the template will replace the directive's element.\n * * `false` - the template will replace the contents of the directive's element.\n *\n * The replacement process migrates all of the attributes / classes from the old element to the new\n * one. See the {@link guide/directive#template-expanding-directive\n * Directives Guide} for an example.\n *\n * There are very few scenarios where element replacement is required for the application function,\n * the main one being reusable custom components that are used within SVG contexts\n * (because SVG doesn't work with custom elements in the DOM tree).\n *\n * #### `transclude`\n * Extract the contents of the element where the directive appears and make it available to the directive.\n * The contents are compiled and provided to the directive as a **transclusion function**. See the\n * {@link $compile#transclusion Transclusion} section below.\n *\n * There are two kinds of transclusion depending upon whether you want to transclude just the contents of the\n * directive's element or the entire element:\n *\n * * `true` - transclude the content (i.e. the child nodes) of the directive's element.\n * * `'element'` - transclude the whole of the directive's element including any directives on this\n * element that defined at a lower priority than this directive. When used, the `template`\n * property is ignored.\n *\n *\n * #### `compile`\n *\n * ```js\n * function compile(tElement, tAttrs, transclude) { ... }\n * ```\n *\n * The compile function deals with transforming the template DOM. Since most directives do not do\n * template transformation, it is not used often. The compile function takes the following arguments:\n *\n * * `tElement` - template element - The element where the directive has been declared. It is\n * safe to do template transformation on the element and child elements only.\n *\n * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared\n * between all directive compile functions.\n *\n * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`\n *\n *
\n * **Note:** The template instance and the link instance may be different objects if the template has\n * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that\n * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration\n * should be done in a linking function rather than in a compile function.\n *
\n\n *
\n * **Note:** The compile function cannot handle directives that recursively use themselves in their\n * own templates or compile functions. Compiling these directives results in an infinite loop and a\n * stack overflow errors.\n *\n * This can be avoided by manually using $compile in the postLink function to imperatively compile\n * a directive's template instead of relying on automatic template compilation via `template` or\n * `templateUrl` declaration or manual compilation inside the compile function.\n *
\n *\n *
\n * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it\n * e.g. does not know about the right outer scope. Please use the transclude function that is passed\n * to the link function instead.\n *
\n\n * A compile function can have a return value which can be either a function or an object.\n *\n * * returning a (post-link) function - is equivalent to registering the linking function via the\n * `link` property of the config object when the compile function is empty.\n *\n * * returning an object with function(s) registered via `pre` and `post` properties - allows you to\n * control when a linking function should be called during the linking phase. See info about\n * pre-linking and post-linking functions below.\n *\n *\n * #### `link`\n * This property is used only if the `compile` property is not defined.\n *\n * ```js\n * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }\n * ```\n *\n * The link function is responsible for registering DOM listeners as well as updating the DOM. It is\n * executed after the template has been cloned. This is where most of the directive logic will be\n * put.\n *\n * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the\n * directive for registering {@link ng.$rootScope.Scope#$watch watches}.\n *\n * * `iElement` - instance element - The element where the directive is to be used. It is safe to\n * manipulate the children of the element only in `postLink` function since the children have\n * already been linked.\n *\n * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared\n * between all directive linking functions.\n *\n * * `controller` - a controller instance - A controller instance if at least one directive on the\n * element defines a controller. The controller is shared among all the directives, which allows\n * the directives to use the controllers as a communication channel.\n *\n * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.\n * This is the same as the `$transclude`\n * parameter of directive controllers, see there for details.\n * `function([scope], cloneLinkingFn, futureParentElement)`.\n *\n * #### Pre-linking function\n *\n * Executed before the child elements are linked. Not safe to do DOM transformation since the\n * compiler linking function will fail to locate the correct elements for linking.\n *\n * #### Post-linking function\n *\n * Executed after the child elements are linked.\n *\n * Note that child elements that contain `templateUrl` directives will not have been compiled\n * and linked since they are waiting for their template to load asynchronously and their own\n * compilation and linking has been suspended until that occurs.\n *\n * It is safe to do DOM transformation in the post-linking function on elements that are not waiting\n * for their async templates to be resolved.\n *\n *\n * ### Transclusion\n *\n * Transclusion is the process of extracting a collection of DOM element from one part of the DOM and\n * copying them to another part of the DOM, while maintaining their connection to the original AngularJS\n * scope from where they were taken.\n *\n * Transclusion is used (often with {@link ngTransclude}) to insert the\n * original contents of a directive's element into a specified place in the template of the directive.\n * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded\n * content has access to the properties on the scope from which it was taken, even if the directive\n * has isolated scope.\n * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.\n *\n * This makes it possible for the widget to have private state for its template, while the transcluded\n * content has access to its originating scope.\n *\n *
\n * **Note:** When testing an element transclude directive you must not place the directive at the root of the\n * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives\n * Testing Transclusion Directives}.\n *
\n *\n * #### Transclusion Functions\n *\n * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion\n * function** to the directive's `link` function and `controller`. This transclusion function is a special\n * **linking function** that will return the compiled contents linked to a new transclusion scope.\n *\n *
\n * If you are just using {@link ngTransclude} then you don't need to worry about this function, since\n * ngTransclude will deal with it for us.\n *
\n *\n * If you want to manually control the insertion and removal of the transcluded content in your directive\n * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery\n * object that contains the compiled DOM, which is linked to the correct transclusion scope.\n *\n * When you call a transclusion function you can pass in a **clone attach function**. This function accepts\n * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded\n * content and the `scope` is the newly created transclusion scope, to which the clone is bound.\n *\n *
\n * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a translude function\n * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.\n *
\n *\n * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone\n * attach function**:\n *\n * ```js\n * var transcludedContent, transclusionScope;\n *\n * $transclude(function(clone, scope) {\n * element.append(clone);\n * transcludedContent = clone;\n * transclusionScope = scope;\n * });\n * ```\n *\n * Later, if you want to remove the transcluded content from your DOM then you should also destroy the\n * associated transclusion scope:\n *\n * ```js\n * transcludedContent.remove();\n * transclusionScope.$destroy();\n * ```\n *\n *
\n * **Best Practice**: if you intend to add and remove transcluded content manually in your directive\n * (by calling the transclude function to get the DOM and and calling `element.remove()` to remove it),\n * then you are also responsible for calling `$destroy` on the transclusion scope.\n *
\n *\n * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}\n * automatically destroy their transluded clones as necessary so you do not need to worry about this if\n * you are simply using {@link ngTransclude} to inject the transclusion into your directive.\n *\n *\n * #### Transclusion Scopes\n *\n * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion\n * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed\n * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it\n * was taken.\n *\n * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look\n * like this:\n *\n * ```html\n *
\n *
\n *
\n *
\n *
\n *
\n * ```\n *\n * The `$parent` scope hierarchy will look like this:\n *\n * ```\n * - $rootScope\n * - isolate\n * - transclusion\n * ```\n *\n * but the scopes will inherit prototypically from different scopes to their `$parent`.\n *\n * ```\n * - $rootScope\n * - transclusion\n * - isolate\n * ```\n *\n *\n * ### Attributes\n *\n * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the\n * `link()` or `compile()` functions. It has a variety of uses.\n *\n * accessing *Normalized attribute names:*\n * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.\n * the attributes object allows for normalized access to\n * the attributes.\n *\n * * *Directive inter-communication:* All directives share the same instance of the attributes\n * object which allows the directives to use the attributes object as inter directive\n * communication.\n *\n * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object\n * allowing other directives to read the interpolated value.\n *\n * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes\n * that contain interpolation (e.g. `src=\"{{bar}}\"`). Not only is this very efficient but it's also\n * the only way to easily get the actual value because during the linking phase the interpolation\n * hasn't been evaluated yet and so the value is at this time set to `undefined`.\n *\n * ```js\n * function linkingFn(scope, elm, attrs, ctrl) {\n * // get the attribute value\n * console.log(attrs.ngModel);\n *\n * // change the attribute\n * attrs.$set('ngModel', 'new value');\n *\n * // observe changes to interpolated attribute\n * attrs.$observe('ngModel', function(value) {\n * console.log('ngModel has changed value to ' + value);\n * });\n * }\n * ```\n *\n * ## Example\n *\n *
\n * **Note**: Typically directives are registered with `module.directive`. The example below is\n * to illustrate how `$compile` works.\n *
\n *\n \n \n \n
\n
\n
\n
\n
\n \n \n it('should auto compile', function() {\n var textarea = $('textarea');\n var output = $('div[compile]');\n // The initial state reads 'Hello Angular'.\n expect(output.getText()).toBe('Hello Angular');\n textarea.clear();\n textarea.sendKeys('{{name}}!');\n expect(output.getText()).toBe('Angular!');\n });\n \n \n\n *\n *\n * @param {string|DOMElement} element Element or HTML string to compile into a template function.\n * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.\n *\n *
\n * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it\n * e.g. will not use the right outer scope. Please pass the transclude function as a\n * `parentBoundTranscludeFn` to the link function instead.\n *
\n *\n * @param {number} maxPriority only apply directives lower than given priority (Only effects the\n * root element(s), not their children)\n * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template\n * (a DOM element/tree) to a scope. Where:\n *\n * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.\n * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the\n * `template` and call the `cloneAttachFn` function allowing the caller to attach the\n * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is\n * called as:
`cloneAttachFn(clonedElement, scope)` where:\n *\n * * `clonedElement` - is a clone of the original `element` passed into the compiler.\n * * `scope` - is the current scope with which the linking function is working with.\n *\n * * `options` - An optional object hash with linking options. If `options` is provided, then the following\n * keys may be used to control linking behavior:\n *\n * * `parentBoundTranscludeFn` - the transclude function made available to\n * directives; if given, it will be passed through to the link functions of\n * directives found in `element` during compilation.\n * * `transcludeControllers` - an object hash with keys that map controller names\n * to controller instances; if given, it will make the controllers\n * available to directives.\n * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add\n * the cloned elements; only needed for transcludes that are allowed to contain non html\n * elements (e.g. SVG elements). See also the directive.controller property.\n *\n * Calling the linking function returns the element of the template. It is either the original\n * element passed in, or the clone of the element if the `cloneAttachFn` is provided.\n *\n * After linking the view is not updated until after a call to $digest which typically is done by\n * Angular automatically.\n *\n * If you need access to the bound view, there are two ways to do it:\n *\n * - If you are not asking the linking function to clone the template, create the DOM element(s)\n * before you send them to the compiler and keep this reference around.\n * ```js\n * var element = $compile('

{{total}}

')(scope);\n * ```\n *\n * - if on the other hand, you need the element to be cloned, the view reference from the original\n * example would not point to the clone, but rather to the original template that was cloned.

While for simple usage patterns this doesn't matter much, for advanced usage\n * it is important to familiarize yourself with these APIs and the guarantees they provide.\n *\n *\n * ## General usage\n * The `$http` service is a function which takes a single argument — a configuration object —\n * that is used to generate an HTTP request and returns a {@link ng.$q promise}\n * with two $http specific methods: `success` and `error`.\n *\n * ```js\n * // Simple GET request example :\n * $http.get('/someUrl').\n * success(function(data, status, headers, config) {\n * // this callback will be called asynchronously\n * // when the response is available\n * }).\n * error(function(data, status, headers, config) {\n * // called asynchronously if an error occurs\n * // or server returns response with an error status.\n * });\n * ```\n *\n * ```js\n * // Simple POST request example (passing data) :\n * $http.post('/someUrl', {msg:'hello word!'}).\n * success(function(data, status, headers, config) {\n * // this callback will be called asynchronously\n * // when the response is available\n * }).\n * error(function(data, status, headers, config) {\n * // called asynchronously if an error occurs\n * // or server returns response with an error status.\n * });\n * ```\n *\n *\n * Since the returned value of calling the $http function is a `promise`, you can also use\n * the `then` method to register callbacks, and these callbacks will receive a single argument –\n * an object representing the response. See the API signature and type info below for more\n * details.\n *\n * A response status code between 200 and 299 is considered a success status and\n * will result in the success callback being called. Note that if the response is a redirect,\n * XMLHttpRequest will transparently follow it, meaning that the error callback will not be\n * called for such responses.\n *\n * ## Writing Unit Tests that use $http\n * When unit testing (using {@link ngMock ngMock}), it is necessary to call\n * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending\n * request using trained responses.\n *\n * ```\n * $httpBackend.expectGET(...);\n * $http.get(...);\n * $httpBackend.flush();\n * ```\n *\n * ## Shortcut methods\n *\n * Shortcut methods are also available. All shortcut methods require passing in the URL, and\n * request data must be passed in for POST/PUT requests.\n *\n * ```js\n * $http.get('/someUrl').success(successCallback);\n * $http.post('/someUrl', data).success(successCallback);\n * ```\n *\n * Complete list of shortcut methods:\n *\n * - {@link ng.$http#get $http.get}\n * - {@link ng.$http#head $http.head}\n * - {@link ng.$http#post $http.post}\n * - {@link ng.$http#put $http.put}\n * - {@link ng.$http#delete $http.delete}\n * - {@link ng.$http#jsonp $http.jsonp}\n * - {@link ng.$http#patch $http.patch}\n *\n *\n * ## Setting HTTP Headers\n *\n * The $http service will automatically add certain HTTP headers to all requests. These defaults\n * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration\n * object, which currently contains this default configuration:\n *\n * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):\n * - `Accept: application/json, text/plain, * / *`\n * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)\n * - `Content-Type: application/json`\n * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)\n * - `Content-Type: application/json`\n *\n * To add or overwrite these defaults, simply add or remove a property from these configuration\n * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object\n * with the lowercased HTTP method name as the key, e.g.\n * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }.\n *\n * The defaults can also be set at runtime via the `$http.defaults` object in the same\n * fashion. For example:\n *\n * ```\n * module.run(function($http) {\n * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'\n * });\n * ```\n *\n * In addition, you can supply a `headers` property in the config object passed when\n * calling `$http(config)`, which overrides the defaults without changing them globally.\n *\n * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,\n * Use the `headers` property, setting the desired header to `undefined`. For example:\n *\n * ```js\n * var req = {\n * method: 'POST',\n * url: 'http://example.com',\n * headers: {\n * 'Content-Type': undefined\n * },\n * data: { test: 'test' },\n * }\n *\n * $http(req).success(function(){...}).error(function(){...});\n * ```\n *\n * ## Transforming Requests and Responses\n *\n * Both requests and responses can be transformed using transformation functions: `transformRequest`\n * and `transformResponse`. These properties can be a single function that returns\n * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,\n * which allows you to `push` or `unshift` a new transformation function into the transformation chain.\n *\n * ### Default Transformations\n *\n * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and\n * `defaults.transformResponse` properties. If a request does not provide its own transformations\n * then these will be applied.\n *\n * You can augment or replace the default transformations by modifying these properties by adding to or\n * replacing the array.\n *\n * Angular provides the following default transformations:\n *\n * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):\n *\n * - If the `data` property of the request configuration object contains an object, serialize it\n * into JSON format.\n *\n * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):\n *\n * - If XSRF prefix is detected, strip it (see Security Considerations section below).\n * - If JSON response is detected, deserialize it using a JSON parser.\n *\n *\n * ### Overriding the Default Transformations Per Request\n *\n * If you wish override the request/response transformations only for a single request then provide\n * `transformRequest` and/or `transformResponse` properties on the configuration object passed\n * into `$http`.\n *\n * Note that if you provide these properties on the config object the default transformations will be\n * overwritten. If you wish to augment the default transformations then you must include them in your\n * local transformation array.\n *\n * The following code demonstrates adding a new response transformation to be run after the default response\n * transformations have been run.\n *\n * ```js\n * function appendTransform(defaults, transform) {\n *\n * // We can't guarantee that the default transformation is an array\n * defaults = angular.isArray(defaults) ? defaults : [defaults];\n *\n * // Append the new transformation to the defaults\n * return defaults.concat(transform);\n * }\n *\n * $http({\n * url: '...',\n * method: 'GET',\n * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {\n * return doTransform(value);\n * })\n * });\n * ```\n *\n *\n * ## Caching\n *\n * To enable caching, set the request configuration `cache` property to `true` (to use default\n * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).\n * When the cache is enabled, `$http` stores the response from the server in the specified\n * cache. The next time the same request is made, the response is served from the cache without\n * sending a request to the server.\n *\n * Note that even if the response is served from cache, delivery of the data is asynchronous in\n * the same way that real requests are.\n *\n * If there are multiple GET requests for the same URL that should be cached using the same\n * cache, but the cache is not populated yet, only one request to the server will be made and\n * the remaining requests will be fulfilled using the response from the first request.\n *\n * You can change the default cache to a new object (built with\n * {@link ng.$cacheFactory `$cacheFactory`}) by updating the\n * {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set\n * their `cache` property to `true` will now use this cache object.\n *\n * If you set the default cache to `false` then only requests that specify their own custom\n * cache object will be cached.\n *\n * ## Interceptors\n *\n * Before you start creating interceptors, be sure to understand the\n * {@link ng.$q $q and deferred/promise APIs}.\n *\n * For purposes of global error handling, authentication, or any kind of synchronous or\n * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be\n * able to intercept requests before they are handed to the server and\n * responses before they are handed over to the application code that\n * initiated these requests. The interceptors leverage the {@link ng.$q\n * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.\n *\n * The interceptors are service factories that are registered with the `$httpProvider` by\n * adding them to the `$httpProvider.interceptors` array. The factory is called and\n * injected with dependencies (if specified) and returns the interceptor.\n *\n * There are two kinds of interceptors (and two kinds of rejection interceptors):\n *\n * * `request`: interceptors get called with a http `config` object. The function is free to\n * modify the `config` object or create a new one. The function needs to return the `config`\n * object directly, or a promise containing the `config` or a new `config` object.\n * * `requestError`: interceptor gets called when a previous interceptor threw an error or\n * resolved with a rejection.\n * * `response`: interceptors get called with http `response` object. The function is free to\n * modify the `response` object or create a new one. The function needs to return the `response`\n * object directly, or as a promise containing the `response` or a new `response` object.\n * * `responseError`: interceptor gets called when a previous interceptor threw an error or\n * resolved with a rejection.\n *\n *\n * ```js\n * // register the interceptor as a service\n * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {\n * return {\n * // optional method\n * 'request': function(config) {\n * // do something on success\n * return config;\n * },\n *\n * // optional method\n * 'requestError': function(rejection) {\n * // do something on error\n * if (canRecover(rejection)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(rejection);\n * },\n *\n *\n *\n * // optional method\n * 'response': function(response) {\n * // do something on success\n * return response;\n * },\n *\n * // optional method\n * 'responseError': function(rejection) {\n * // do something on error\n * if (canRecover(rejection)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(rejection);\n * }\n * };\n * });\n *\n * $httpProvider.interceptors.push('myHttpInterceptor');\n *\n *\n * // alternatively, register the interceptor via an anonymous factory\n * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {\n * return {\n * 'request': function(config) {\n * // same as above\n * },\n *\n * 'response': function(response) {\n * // same as above\n * }\n * };\n * });\n * ```\n *\n * ## Security Considerations\n *\n * When designing web applications, consider security threats from:\n *\n * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)\n *\n * Both server and the client must cooperate in order to eliminate these threats. Angular comes\n * pre-configured with strategies that address these issues, but for this to work backend server\n * cooperation is required.\n *\n * ### JSON Vulnerability Protection\n *\n * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n * allows third party website to turn your JSON resource URL into\n * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To\n * counter this your server can prefix all JSON requests with following string `\")]}',\\n\"`.\n * Angular will automatically strip the prefix before processing it as JSON.\n *\n * For example if your server needs to return:\n * ```js\n * ['one','two']\n * ```\n *\n * which is vulnerable to attack, your server can return:\n * ```js\n * )]}',\n * ['one','two']\n * ```\n *\n * Angular will strip the prefix, before processing the JSON.\n *\n *\n * ### Cross Site Request Forgery (XSRF) Protection\n *\n * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which\n * an unauthorized site can gain your user's private data. Angular provides a mechanism\n * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie\n * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only\n * JavaScript that runs on your domain could read the cookie, your server can be assured that\n * the XHR came from JavaScript running on your domain. The header will not be set for\n * cross-domain requests.\n *\n * To take advantage of this, your server needs to set a token in a JavaScript readable session\n * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the\n * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure\n * that only JavaScript running on your domain could have sent the request. The token must be\n * unique for each user and must be verifiable by the server (to prevent the JavaScript from\n * making up its own tokens). We recommend that the token is a digest of your site's\n * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))\n * for added security.\n *\n * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName\n * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,\n * or the per-request config object.\n *\n *\n * @param {object} config Object describing the request to be made and how it should be\n * processed. The object has following properties:\n *\n * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)\n * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.\n * - **params** – `{Object.}` – Map of strings or objects which will be turned\n * to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be\n * JSONified.\n * - **data** – `{string|Object}` – Data to be sent as the request message data.\n * - **headers** – `{Object}` – Map of strings or functions which return strings representing\n * HTTP headers to send to the server. If the return value of a function is null, the\n * header will not be sent.\n * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.\n * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.\n * - **transformRequest** –\n * `{function(data, headersGetter)|Array.}` –\n * transform function or an array of such functions. The transform function takes the http\n * request body and headers and returns its transformed (typically serialized) version.\n * See {@link ng.$http#overriding-the-default-transformations-per-request\n * Overriding the Default Transformations}\n * - **transformResponse** –\n * `{function(data, headersGetter, status)|Array.}` –\n * transform function or an array of such functions. The transform function takes the http\n * response body, headers and status and returns its transformed (typically deserialized) version.\n * See {@link ng.$http#overriding-the-default-transformations-per-request\n * Overriding the Default Transformations}\n * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the\n * GET request, otherwise if a cache instance built with\n * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for\n * caching.\n * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}\n * that should abort the request when resolved.\n * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the\n * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)\n * for more information.\n * - **responseType** - `{string}` - see\n * [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).\n *\n * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the\n * standard `then` method and two http specific methods: `success` and `error`. The `then`\n * method takes two arguments a success and an error callback which will be called with a\n * response object. The `success` and `error` methods take a single argument - a function that\n * will be called when the request succeeds or fails respectively. The arguments passed into\n * these functions are destructured representation of the response object passed into the\n * `then` method. The response object has these properties:\n *\n * - **data** – `{string|Object}` – The response body transformed with the transform\n * functions.\n * - **status** – `{number}` – HTTP status code of the response.\n * - **headers** – `{function([headerName])}` – Header getter function.\n * - **config** – `{Object}` – The configuration object that was used to generate the request.\n * - **statusText** – `{string}` – HTTP status text of the response.\n *\n * @property {Array.} pendingRequests Array of config objects for currently pending\n * requests. This is primarily meant to be used for debugging purposes.\n *\n *\n * @example\n\n\n

So, for HTML elements interpolated\n * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter\n * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,\n * this is typically useful only when user-data is used in rendering a template from the server, or\n * when otherwise untrusted data is used by a directive.\n *\n * \n * \n *

This is similar to the native Promise implementation from ES6 Harmony,\n * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).\n *\n * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are\n * available yet.\n *\n * It can be used like so:\n *\n * ```js\n * // for the purpose of this example let's assume that variables `$q` and `okToGreet`\n * // are available in the current lexical scope (they could have been injected or passed in).\n *\n * function asyncGreet(name) {\n * // perform some asynchronous operation, resolve or reject the promise when appropriate.\n * return $q(function(resolve, reject) {\n * setTimeout(function() {\n * if (okToGreet(name)) {\n * resolve('Hello, ' + name + '!');\n * } else {\n * reject('Greeting ' + name + ' is not allowed.');\n * }\n * }, 1000);\n * });\n * }\n *\n * var promise = asyncGreet('Robin Hood');\n * promise.then(function(greeting) {\n * alert('Success: ' + greeting);\n * }, function(reason) {\n * alert('Failed: ' + reason);\n * });\n * ```\n *\n * Note: progress/notify callbacks are not currently supported via the ES6-style interface.\n *\n * However, the more traditional CommonJS-style usage is still available, and documented below.\n *\n * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an\n * interface for interacting with an object that represents the result of an action that is\n * performed asynchronously, and may or may not be finished at any given point in time.\n *\n * From the perspective of dealing with error handling, deferred and promise APIs are to\n * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.\n *\n * ```js\n * // for the purpose of this example let's assume that variables `$q` and `okToGreet`\n * // are available in the current lexical scope (they could have been injected or passed in).\n *\n * function asyncGreet(name) {\n * var deferred = $q.defer();\n *\n * setTimeout(function() {\n * deferred.notify('About to greet ' + name + '.');\n *\n * if (okToGreet(name)) {\n * deferred.resolve('Hello, ' + name + '!');\n * } else {\n * deferred.reject('Greeting ' + name + ' is not allowed.');\n * }\n * }, 1000);\n *\n * return deferred.promise;\n * }\n *\n * var promise = asyncGreet('Robin Hood');\n * promise.then(function(greeting) {\n * alert('Success: ' + greeting);\n * }, function(reason) {\n * alert('Failed: ' + reason);\n * }, function(update) {\n * alert('Got notification: ' + update);\n * });\n * ```\n *\n * At first it might not be obvious why this extra complexity is worth the trouble. The payoff\n * comes in the way of guarantees that promise and deferred APIs make, see\n * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.\n *\n * Additionally the promise api allows for composition that is very hard to do with the\n * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.\n * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the\n * section on serial or parallel joining of promises.\n *\n * # The Deferred API\n *\n * A new instance of deferred is constructed by calling `$q.defer()`.\n *\n * The purpose of the deferred object is to expose the associated Promise instance as well as APIs\n * that can be used for signaling the successful or unsuccessful completion, as well as the status\n * of the task.\n *\n * **Methods**\n *\n * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection\n * constructed via `$q.reject`, the promise will be rejected instead.\n * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to\n * resolving it with a rejection constructed via `$q.reject`.\n * - `notify(value)` - provides updates on the status of the promise's execution. This may be called\n * multiple times before the promise is either resolved or rejected.\n *\n * **Properties**\n *\n * - promise – `{Promise}` – promise object associated with this deferred.\n *\n *\n * # The Promise API\n *\n * A new promise instance is created when a deferred instance is created and can be retrieved by\n * calling `deferred.promise`.\n *\n * The purpose of the promise object is to allow for interested parties to get access to the result\n * of the deferred task when it completes.\n *\n * **Methods**\n *\n * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or\n * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously\n * as soon as the result is available. The callbacks are called with a single argument: the result\n * or rejection reason. Additionally, the notify callback may be called zero or more times to\n * provide a progress indication, before the promise is resolved or rejected.\n *\n * This method *returns a new promise* which is resolved or rejected via the return value of the\n * `successCallback`, `errorCallback`. It also notifies via the return value of the\n * `notifyCallback` method. The promise cannot be resolved or rejected from the notifyCallback\n * method.\n *\n * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`\n *\n * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,\n * but to do so without modifying the final value. This is useful to release resources or do some\n * clean-up that needs to be done whether the promise was rejected or resolved. See the [full\n * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for\n * more information.\n *\n * # Chaining promises\n *\n * Because calling the `then` method of a promise returns a new derived promise, it is easily\n * possible to create a chain of promises:\n *\n * ```js\n * promiseB = promiseA.then(function(result) {\n * return result + 1;\n * });\n *\n * // promiseB will be resolved immediately after promiseA is resolved and its value\n * // will be the result of promiseA incremented by 1\n * ```\n *\n * It is possible to create chains of any length and since a promise can be resolved with another\n * promise (which will defer its resolution further), it is possible to pause/defer resolution of\n * the promises at any point in the chain. This makes it possible to implement powerful APIs like\n * $http's response interceptors.\n *\n *\n * # Differences between Kris Kowal's Q and $q\n *\n * There are two main differences:\n *\n * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation\n * mechanism in angular, which means faster propagation of resolution or rejection into your\n * models and avoiding unnecessary browser repaints, which would result in flickering UI.\n * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains\n * all the important functionality needed for common async tasks.\n *\n * # Testing\n *\n * ```js\n * it('should simulate promise', inject(function($q, $rootScope) {\n * var deferred = $q.defer();\n * var promise = deferred.promise;\n * var resolvedValue;\n *\n * promise.then(function(value) { resolvedValue = value; });\n * expect(resolvedValue).toBeUndefined();\n *\n * // Simulate resolving of promise\n * deferred.resolve(123);\n * // Note that the 'then' function does not get called synchronously.\n * // This is because we want the promise API to always be async, whether or not\n * // it got called synchronously or asynchronously.\n * expect(resolvedValue).toBeUndefined();\n *\n * // Propagate promise resolution to 'then' functions using $apply().\n * $rootScope.$apply();\n * expect(resolvedValue).toEqual(123);\n * }));\n * ```\n *\n * @param {function(function, function)} resolver Function which is responsible for resolving or\n * rejecting the newly created promise.

One example of\n * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer\n * to these contexts as privileged or SCE contexts.\n *\n * As of version 1.2, Angular ships with SCE enabled by default.\n *\n * Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow\n * one to execute arbitrary javascript by the use of the expression() syntax. Refer\n * to learn more about them.\n * You can ensure your document is in standards mode and not quirks mode by adding ``\n * to the top of your HTML document.\n *\n * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for\n * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.\n *\n * Here's an example of a binding in a privileged context:\n *\n * ```\n * \n *
\n * ```\n *\n * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE\n * disabled, this application allows the user to render arbitrary HTML into the DIV.\n * In a more realistic example, one may be rendering user comments, blog articles, etc. via\n * bindings. (HTML is just one example of a context where rendering user controlled input creates\n * security vulnerabilities.)\n *\n * For the case of HTML, you might use a library, either on the client side, or on the server side,\n * to sanitize unsafe HTML before binding to the value and rendering it in the document.\n *\n * How would you ensure that every place that used these types of bindings was bound to a value that\n * was sanitized by your library (or returned as safe for rendering by your server?) How can you\n * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some\n * properties/fields and forgot to update the binding to the sanitized value?\n *\n * To be secure by default, you want to ensure that any such bindings are disallowed unless you can\n * determine that something explicitly says it's safe to use a value for binding in that\n * context. You can then audit your code (a simple grep would do) to ensure that this is only done\n * for those values that you can easily tell are safe - because they were received from your server,\n * sanitized by your library, etc. You can organize your codebase to help with this - perhaps\n * allowing only the files in a specific directory to do this. Ensuring that the internal API\n * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.\n *\n * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}\n * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to\n * obtain values that will be accepted by SCE / privileged contexts.\n *\n *\n * ## How does it work?\n *\n * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted\n * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link\n * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the\n * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.\n *\n * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link\n * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly\n * simplified):\n *\n * ```\n * var ngBindHtmlDirective = ['$sce', function($sce) {\n * return function(scope, element, attr) {\n * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {\n * element.html(value || '');\n * });\n * };\n * }];\n * ```\n *\n * ## Impact on loading templates\n *\n * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as\n * `templateUrl`'s specified by {@link guide/directive directives}.\n *\n * By default, Angular only loads templates from the same domain and protocol as the application\n * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl\n * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or\n * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist\n * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.\n *\n * *Please note*:\n * The browser's\n * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)\n * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)\n * policy apply in addition to this and may further restrict whether the template is successfully\n * loaded. This means that without the right CORS policy, loading templates from a different domain\n * won't work on all browsers. Also, loading templates from `file://` URL does not work on some\n * browsers.\n *\n * ## This feels like too much overhead\n *\n * It's important to remember that SCE only applies to interpolation expressions.\n *\n * If your expressions are constant literals, they're automatically trusted and you don't need to\n * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.\n * `
implicitly trusted'\">
`) just works.\n *\n * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them\n * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.\n *\n * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load\n * templates in `ng-include` from your application's domain without having to even know about SCE.\n * It blocks loading templates from other domains or loading templates over http from an https\n * served document. You can change these by setting your own custom {@link\n * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link\n * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.\n *\n * This significantly reduces the overhead. It is far easier to pay the small overhead and have an\n * application that's secure and can be audited to verify that with much more ease than bolting\n * security onto an application later.\n *\n * \n * ## What trusted context types are supported?\n *\n * | Context | Notes |\n * |---------------------|----------------|\n * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |\n * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |\n * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |\n * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |\n *\n * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} \n *\n * Each element in these arrays must be one of the following:\n *\n * - **'self'**\n * - The special **string**, `'self'`, can be used to match against all URLs of the **same\n * domain** as the application document using the **same protocol**.\n * - **String** (except the special value `'self'`)\n * - The string is matched against the full *normalized / absolute URL* of the resource\n * being tested (substring matches are not good enough.)\n * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters\n * match themselves.\n * - `*`: matches zero or more occurrences of any character other than one of the following 6\n * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'. It's a useful wildcard for use\n * in a whitelist.\n * - `**`: matches zero or more occurrences of *any* character. As such, it's not\n * not appropriate to use in for a scheme, domain, etc. as it would match too much. (e.g.\n * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might\n * not have been the intention.) Its usage at the very end of the path is ok. (e.g.\n * http://foo.example.com/templates/**).\n * - **RegExp** (*see caveat below*)\n * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax\n * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to\n * accidentally introduce a bug when one updates a complex expression (imho, all regexes should\n * have good test coverage.). For instance, the use of `.` in the regex is correct only in a\n * small number of cases. A `.` character in the regex used when matching the scheme or a\n * subdomain could be matched against a `:` or literal `.` that was likely not intended. It\n * is highly recommended to use the string patterns and only fall back to regular expressions\n * if they as a last resort.\n * - The regular expression must be an instance of RegExp (i.e. not a string.) It is\n * matched against the **entire** *normalized / absolute URL* of the resource being tested\n * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags\n * present on the RegExp (such as multiline, global, ignoreCase) are ignored.\n * - If you are generating your JavaScript from some other templating engine (not\n * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),\n * remember to escape your regular expression (and be aware that you might need more than\n * one level of escaping depending on your templating engine and the way you interpolated\n * the value.) Do make use of your platform's escaping mechanism as it might be good\n * enough before coding your own. e.g. Ruby has\n * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)\n * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).\n * Javascript lacks a similar built in function for escaping. Take a look at Google\n * Closure library's [goog.string.regExpEscape(s)](\n * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).\n *\n * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.\n *\n * ## Show me an example using SCE.\n *\n * \n * \n *

It might make sense to disable SCE\n * for cases where you have a lot of existing code that was written before SCE was introduced and\n * you're migrating them a module at a time.\n *\n * That said, here's how you can completely disable SCE:\n *\n * ```\n * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {\n * // Completely disable SCE. For demonstration purposes only!\n * // Do not use in new projects.\n * $sceProvider.enabled(false);\n * });\n * ```\n *\n */\n/* jshint maxlen: 100 */\n\nfunction $SceProvider() {\n var enabled = true;\n\n /**\n * @ngdoc method\n * @name $sceProvider#enabled\n * @kind function\n *\n * @param {boolean=} value If provided, then enables/disables SCE.\n * @return {boolean} true if SCE is enabled, false otherwise.\n *\n * @description\n * Enables/disables SCE and returns the current value.\n */\n this.enabled = function(value) {\n if (arguments.length) {\n enabled = !!value;\n }\n return enabled;\n };\n\n\n /* Design notes on the default implementation for SCE.\n *\n * The API contract for the SCE delegate\n * -------------------------------------\n * The SCE delegate object must provide the following 3 methods:\n *\n * - trustAs(contextEnum, value)\n * This method is used to tell the SCE service that the provided value is OK to use in the\n * contexts specified by contextEnum. It must return an object that will be accepted by\n * getTrusted() for a compatible contextEnum and return this value.\n *\n * - valueOf(value)\n * For values that were not produced by trustAs(), return them as is. For values that were\n * produced by trustAs(), return the corresponding input value to trustAs. Basically, if\n * trustAs is wrapping the given values into some type, this operation unwraps it when given\n * such a value.\n *\n * - getTrusted(contextEnum, value)\n * This function should return the a value that is safe to use in the context specified by\n * contextEnum or throw and exception otherwise.\n *\n * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be\n * opaque or wrapped in some holder object. That happens to be an implementation detail. For\n * instance, an implementation could maintain a registry of all trusted objects by context. In\n * such a case, trustAs() would return the same object that was passed in. getTrusted() would\n * return the same object passed in if it was found in the registry under a compatible context or\n * throw an exception otherwise. An implementation might only wrap values some of the time based\n * on some criteria. getTrusted() might return a value and not throw an exception for special\n * constants or objects even if not wrapped. All such implementations fulfill this contract.\n *\n *\n * A note on the inheritance model for SCE contexts\n * ------------------------------------------------\n * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This\n * is purely an implementation details.\n *\n * The contract is simply this:\n *\n * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)\n * will also succeed.\n *\n * Inheritance happens to capture this in a natural way. In some future, we\n * may not use inheritance anymore. That is OK because no code outside of\n * sce.js and sceSpecs.js would need to be aware of this detail.\n */\n\n this.$get = ['$parse', '$sceDelegate', function(\n $parse, $sceDelegate) {\n // Prereq: Ensure that we're not running in IE<11 quirks mode.

Normalizing means that a relative\n * URL will be resolved into an absolute URL in the context of the application document.\n * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related\n * properties are all populated to reflect the normalized URL. This approach has wide\n * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See\n * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n *\n * Implementation Notes for IE\n * ---------------------------\n * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other\n * browsers. However, the parsed components will not be set if the URL assigned did not specify\n * them. (e.g. if you assign a.href = \"foo\", then a.protocol, a.host, etc. will be empty.) We\n * work around that by performing the parsing in a 2nd step by taking a previously normalized\n * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the\n * properties such as protocol, hostname, port, etc.\n *\n * IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one\n * uses the inner HTML approach to assign the URL as part of an HTML snippet -\n * http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL.\n * Unfortunately, setting img[src] to something like \"javascript:foo\" on IE throws an exception.\n * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that\n * method and IE < 8 is unsupported.\n *\n * References:\n * http://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement\n * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n * http://url.spec.whatwg.org/#urlutils\n * https://github.com/angular/angular.js/pull/2902\n * http://james.padolsey.com/javascript/parsing-urls-with-the-dom/\n *\n * @kind function\n * @param {string} url The URL to be parsed.\n * @description Normalizes and parses a URL.\n * @returns {object} Returns the normalized URL as a dictionary.\n *\n * | member name | Description |\n * |---------------|----------------|\n * | href | A normalized version of the provided URL if it was not an absolute URL |\n * | protocol | The protocol including the trailing colon |\n * | host | The host and port (if the port is non-default) of the normalizedUrl |\n * | search | The search params, minus the question mark |\n * | hash | The hash string, minus the hash symbol\n * | hostname | The hostname\n * | port | The port, without \":\"\n * | pathname | The pathname, beginning with \"/\"\n *\n */\nfunction urlResolve(url) {\n var href = url;\n\n if (msie) {\n // Normalize before parse.

Instead some javascript logic should be triggered\n * to handle the form submission in an application-specific way.\n *\n * For this reason, Angular prevents the default action (form submission to the server) unless the\n * `` element has an `action` attribute specified.\n *\n * You can use one of the following two ways to specify what javascript method should be called when\n * a form is submitted:\n *\n * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element\n * - {@link ng.directive:ngClick ngClick} directive on the first\n * button or input field of type submit (input[type=submit])\n *\n * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}\n * or {@link ng.directive:ngClick ngClick} directives.\n * This is because of the following form submission rules in the HTML specification:\n *\n * - If a form has only one input field then hitting enter in this field triggers form submit\n * (`ngSubmit`)\n * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter\n * doesn't trigger submit\n * - if a form has one or more input fields and one or more buttons or input[type=submit] then\n * hitting enter in any of the input fields will trigger the click handler on the *first* button or\n * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)\n *\n * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is\n * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n * to have access to the updated model.\n *\n * ## Animation Hooks\n *\n * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.\n * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any\n * other validations that are performed within the form. Animations in ngForm are similar to how\n * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well\n * as JS animations.\n *\n * The following example shows a simple way to utilize CSS transitions to style a form element\n * that has been rendered as invalid after it has been validated:\n *\n * 
\n * //be sure to include ngAnimate as a module to hook into more\n * //advanced animations\n * .my-form {\n *   transition:0.5s linear all;\n *   background: white;\n * }\n * .my-form.ng-invalid {\n *   background: red;\n *   color:white;\n * }\n *
\n *\n * @example\n \n \n \n \n \n userType: \n Required!
\n userType = {{userType}}
\n myForm.input.$valid = {{myForm.input.$valid}}
\n myForm.input.$error = {{myForm.input.$error}}
\n myForm.$valid = {{myForm.$valid}}
\n myForm.$error.required = {{!!myForm.$error.required}}
\n \n \n \n it('should initialize to model', function() {\n var userType = element(by.binding('userType'));\n var valid = element(by.binding('myForm.input.$valid'));\n\n expect(userType.getText()).toContain('guest');\n expect(valid.getText()).toContain('true');\n });\n\n it('should be invalid if empty', function() {\n var userType = element(by.binding('userType'));\n var valid = element(by.binding('myForm.input.$valid'));\n var userInput = element(by.model('userType'));\n\n userInput.clear();\n userInput.sendKeys('');\n\n expect(userType.getText()).toEqual('userType =');\n expect(valid.getText()).toContain('false');\n });\n \n

\n *\n * @param {string} ngModel Assignable angular expression to data-bind to.\n * @param {string=} name Property name of the form under which the control is published.\n * @param {string=} required Sets `required` validation error key if the value is not entered.\n * @param {boolean=} ngRequired Sets `required` attribute if set to true\n * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than\n * minlength.\n * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than\n * maxlength. Setting the attribute to a negative or non-numeric value, allows view values of any\n * length.\n * @param {string=} ngPattern Sets `pattern` validation error key if the value does not match the\n * RegExp pattern expression. Expected value is `/regexp/` for inline patterns or `regexp` for\n * patterns defined as scope expressions.\n * @param {string=} ngChange Angular expression to be executed when input changes due to user\n * interaction with the input element.\n * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.\n * This parameter is ignored for input[type=password] controls, which will never trim the\n * input.\n *\n * @example\n \n \n \n
