# Contributing
Contributions are always welcome, no matter how large or small. Before
contributing, please read the
[code of conduct](https://github.com/babel/babel/blob/master/CODE_OF_CONDUCT.md).
## Developing
> Note: Babel moves fast. Only the latest release is guaranteed to build correctly.
> Older releases are not officially supported. If you attempt to build them, do that at your own risk.
#### Setup
```sh
$ git clone https://github.com/babel/babel
$ cd babel
$ make bootstrap
```
Then you can either run:
```sh
$ make build-core
```
to build Babel **once** or:
```sh
$ make watch-core
```
to have Babel build itself then incrementally build files on change.
#### Running tests
You can run tests via:
```sh
$ make test
```
This is mostly overkill and you can limit the tests to a select few by directly
running them with `mocha`:
```sh
$ mocha test/core/transformation.js
```
Use mocha's `--grep` option to run a subset of tests by name:
```sh
$ mocha test/core/transformation.js --grep es7
```
If you don't have `mocha` installed globally, you can still use it from Babel's
dependencies in `node_modules`, but make sure `node_modules/.bin` is added to
your [`$PATH`](http://unix.stackexchange.com/questions/26047/how-to-correctly-add-a-path-to-path) environment variable.
#### Workflow
* Fork the repository
* Clone your fork and change directory to it (`git clone git@github.com:yourUserName/babel.git && cd babel`)
* Install the project dependencies (`make bootstrap`)
* Link your forked clone (`npm link`)
* Develop your changes ensuring you're fetching updates from upstream often
* Ensure the test are passing (`make test`)
* Create new pull request explaining your proposed change or reference an issue in your commit message
#### Dependencies
+ [ast-types](http://ghub.io/ast-types) This is required to monkeypatch regenerators AST definitions. Could be improved in the future.
+ [chalk](http://ghub.io/chalk) This is used for terminal color highlighting for syntax errors.
+ [convert-source-map](http://ghub.io/convert-source-map) Turns a source map object into a comment etc.
+ [core-js](http://ghub.io/core-js) Used for the polyfill.
+ [debug](http://ghub.io/debug) Used to output debugging information when NODE_DEBUG is set to babel.
+ [detect-indent](http://ghub.io/detect-indent) This is used in the code generator so it can infer indentation.
+ [estraverse](http://ghub.io/estraverse) The only method on this is attachComments. I'd like to implement our own comment attachment algorithm eventually though.
+ [esutils](http://ghub.io/esutils) Various ES related utilities. Check whether something is a keyword etc.
+ [fs-readdir-recursive](http://ghub.io/fs-readdir-recursive) Recursively search a directory for.
+ [globals](http://ghub.io/globals) A list of JavaScript global variables. This is used by the scope tracking to check for colliding variables.
+ [is-integer](http://ghub.io/is-integer) Checks if something is an integer.
+ [js-tokens](http://ghub.io/js-tokens) This is used to get tokens for syntax error highlighting.
+ [line-numbers](http://ghub.io/line-numbers) Used to produce the code frames in syntax errors.
+ [lodash](http://ghub.io/lodash) Used for various utilities.
+ [minimatch](http://ghub.io/minimatch) This is used to match glob-style ignore/only filters.
+ [output-file-sync](http://ghub.io/output-file-sync) Synchronously writes a file and create its ancestor directories if needed.
+ [path-is-absolute](http://ghub.io/path-is-absolute) Checks if a path is absolute. C:\foo and \foo are considered absolute.
+ [regenerator](http://ghub.io/regenerator) This is used to transform generators/async functions.
+ [regexpu](http://ghub.io/regexpu) Used to transform unicode regex patterns.
+ [repeating](http://ghub.io/repeating) Repeats a string.
+ [shebang-regex](http://ghub.io/shebang-regex) Literally just a regex that matches shebangs.
+ [slash](http://ghub.io/slash) Normalises path separators.
+ [source-map](http://ghub.io/source-map) Generates sourcemaps.
+ [source-map-support](http://ghub.io/source-map-support) Adds source map support to babel-node/babel/register.
+ [strip-json-comments](http://ghub.io/strip-json-comments) Remove comments from a JSON string. This is used for .babelrc files.
+ [to-fast-properties](http://ghub.io/to-fast-properties) A V8 trick to put an object into fast properties mode.
+ [trim-right](http://ghub.io/trim-right) Trims the rightside whitespace.
+ [path-exists](https://www.npmjs.com/package/path-exists) Checks if a path exists. (replaces the deprecated `fs.exists` methods)
+ [home-or-tmp](https://github.com/sindresorhus/home-or-tmp) Gets the user home directory with fallback to the system temporary directory. This is used to resolve the babel-node/babel/register cache.
+ [resolve](https://www.npmjs.com/package/resolve) Implements the [`require.resolve()` algorithm](http://nodejs.org/docs/v0.12.0/api/all.html#all_require_resolve) such that we can `require.resolve()` on behalf of a file asynchronously and synchronously.
#### Code Standards
* **General**
* Max of five arguments for functions
* Max depth of four nested blocks
* 2-spaced soft tabs
* **Naming**
* CamelCase all class names
* camelBack all variable names
* **Spacing**
* Spaces after all keywords
* Spaces before all left curly braces
* **Comments**
* Use JSDoc-style comments for methods
* Single-line comments for ambiguous code
* **Quotes**
* Always use double quotes
* Only use single quotes when the string contains a double quote
* **Declaration**
* No unused variables
* No pollution of global variables and prototypes
#### Internals
Please see [`/doc`](/doc) for internals documentation relevant to developing babel.

# Properties of nodes
These are properties babel stores in AST node objects for internal use, as opposed to properties that are part of the AST spec ([ESTree](https://github.com/estree/estree) at the time of this writing).
## `_blockHoist`
`node._blockHoist != null` triggers the [block-hoist transformer](/src/babel/transformation/transformers/internal/block-hoist.js). Value should be `true` or an integer in the range `0..3`. `true` is equivalent to `2`. The value indicates whether the node should be hoisted and to what degree. See the source code for more detailed information.
## `_paths`
Stores a representation of a node's position in the tree and relationship to other nodes.
## `shadow`
A truthy value on a function node triggers the [shadow-functions transformer](/src/babel/transformation/transformers/internal/shadow-functions.js), which transforms the node so that it references (or inherits) `arguments` and the `this` context from the parent scope. It is invoked for arrow functions, for example.

## Welcome to the Babel Codebase
Babel is broken down into three parts:
- Parsing
- [Transformation](babel/transformation/)
- [Generation](babel/generation/)
**Parsing** is the process of turning a piece of code into an [ESTree spec](https://github.com/estree/estree) compatible AST (Abstract
Syntax Tree) which is a tree-like object of nodes that _describes_ the code.
This makes it easier to transform the code over direct string manpulation.
**Transformation** is the process of taking an AST and manipulating it into
a new one. For example, Babel might take an ES2015 ArrowFunction and transform
it into a normal Function which will work in ES5 environments.
**Generation** is the process of turning an AST back into code. After Babel is
done transforming the AST, the generation takes over to return normal code.
---
Babel's parsing step is done by [Acorn](https://github.com/marijnh/acorn). However, because Babel is implementing
future standards it maintains a [fork of Acorn](acorn/) in order to do it's job. You can
see that fork in the "acorn" folder.
The transformation and generation steps are both handled inside of the Babel
codebase itself, which is in the "babel" folder here.

// A recursive descent parser operates by defining functions for all
// syntactic elements, and recursively calling those, each function
// advancing the input stream and returning an AST node. Precedence
// of constructs (for example, the fact that `!x[1]` means `!(x[1])`
// instead of `(!x)[1]` is handled by the fact that the parser
// function that parses unary prefix operators is called first, and
// in turn calls the function that parses `[]` subscripts — that
// way, it'll receive the node for `x[1]` already parsed, and wraps
// *that* in the unary operator node.
//
// Acorn uses an [operator precedence parser][opp] to handle binary
// operator precedence, because it is much more compact than using
// the technique outlined above, which uses different, nesting
// functions to specify precedence, for all of the ten binary
// precedence levels that JavaScript defines.

## Diving into Babel
If you look around in the various directories in here you'll find some details
about the organization of the Babel codebase.

## API
In this directory you'll find all the public interfaces to using Babel for both
node and the browser.
### Node
There are two ways people use Babel within Node, they either are manipulating
strings of code with `babel.transform` or `babel.parse`, they also might be
running their code through Babel before execution via `register` or `polyfill`.
### Browser
Usage of Babel in the browser is extremely uncommon and in most cases
considered A Bad Idea™. However it works by loading `<script>`'s with XHR,
transforming them and then executing them. These `<script>`'s need to have a
`type` of "text/ecmascript-6", "text/babel", or "module" ("text/6to5" exists as
well for legacy reasons).
