The goal is to convert a subset (or full set) of Elixir code to JavaScript, providing the ability to write JavaScript in Elixir. This is done by taking the Elixir AST and converting it into JavaScript AST and then to JavaScript code. This is done using the Elixir-ESTree library.

• Elixir
• Node or io.js (only for development)

ElixirScript can be used in the following ways:

• If using as part of a project, you can add the following to your deps

    {:elixir_script, "~> 0.7"}

  From there you can either use the ElixirScript module directly or the mix command, mix ex2js

• CLI Client

  You can download the latest release from the releases page and use the included ex2js escript.

Clone the repo

git clone [email protected]:bryanjos/elixirscript.git

Get dependencies

mix deps.get
npm install

Compile

mix compile

Test

mix test

To build distributable tarball

mix ex2js.dist

`ex2js.tar.gz` will be in the `dist` folder

  usage: ex2js <input> [options]

  <input> path to elixir files or 
          the elixir code string if the -ex flag is used

  options:
  -o  --output [path]   places output at the given path
  -ex --elixir          read input as elixir code string
  -r  --root [path]     root path for standard libs
  -h  --help            this message

#Limitations

The following aren't defined (yet):

• __CALLER__
• __ENV__
• quote
• unquote
• unquote_slicing
• super

A lot of functions in the Kernel module are implemented. The Enum, Atom, List, Tuple, Logger, and Range modules are either fully defined are not complete. The rest still need to be implemented. Some modules like System or File may not be useful or function in the browser and may end up being only useful when using ElixirScript outside of the browser.

Not sure how this would be implemented right now, but looking for ideas.

Only because the translation of else haven't been figured out yet

Currently pattern matching on bitstrings isn't supported, but for every other case that one would use pattern matching, it should work.

There are probably more that I'm forgetting. Check the issues for what's implemented and what still is needed.
