Elixir is a dynamic, functional language designed for building scalable and maintainable applications.
For more about Elixir, installation and documentation,check Elixir's website.
All security releases [will be tagged with

All interactions in our official communication channels follow our Code of Conduct.
For the many different ways to install Elixir,see our installation instructions on the website. To compile from source, you can follow the steps below.
First, install Erlang. Then clone this repository to your machine, compile and test it:
git clone https://github.com/elixir-lang/elixir.git cd elixir make clean test
Note: if you are running on Windows,this article includes important notes for compiling Elixir from source on Windows.
If Elixir fails to build (specifically when pulling in a new version via
), be sure to remove any previous build artifacts by running
If tests pass, you can use Interactive Elixir by running
in your terminal.
However, if tests fail, it is likely that you have an outdated Erlang/OTP version (Elixir requires Erlang/OTP 21.0 or later). You can check your Erlang/OTP version by calling
in the command line. You will see some information similar to:
Erlang/OTP 21 [erts-9.0] [smp:2:2] [async-threads:10] [kernel-poll:false]
If you have properly set up your dependencies and tests still fail, you may want to open up a bug report, as explained next.
For proposing new features, please start a discussion in theElixir Core mailing list. Keep in mind that it is your responsibility to argue and explain why a feature is useful and how it will impact the codebase and the community.
Once a proposal is accepted, it will be added to the issue tracker. The issue tracker focuses on actionable items and it holds a list of upcoming enhancements and pending bugs. All entries in the tracker are tagged for clarity and to ease collaboration.
Features and bug fixes that have already been merged and will be included in the next release are marked as "closed" in the issue tracker and are added to the changelog.
We welcome everyone to contribute to Elixir. To do so, there are a few things you need to know about the code. First, Elixir code is divided in applications inside the
You can run all tests in the root directory with
and you can also run tests for a specific framework
, for example,
. If you just changed something in the Elixir's standard library, you can run only that portion through
If you are changing just one file, you can choose to compile and run tests only for that particular file for fast development cycles. For example, if you are changing the String module, you can compile it and run its tests as:
bin/elixirc lib/elixir/lib/string.ex -o lib/elixir/ebin bin/elixir lib/elixir/test/elixir/string\_test.exs
To recompile (including Erlang modules):
After your changes are done, please remember to run
to guarantee all files are properly formatted and then run the full suite with
If your contribution fails during the bootstrapping of the language, you can rebuild the language from scratch with:
make clean\_elixir compile
Similarly, if you can't get Elixir to compile or the tests to pass after updating an existing checkout, run
make clean compile
With tests running and passing, you are ready to contribute to Elixir andsend a pull request. We have saved some excellent pull requests we have received in the past in case you are looking for some examples:
Once a pull request is sent, the Elixir team will review your changes. We outline our process below to clarify the roles of everyone involved.
All pull requests must be approved by two committers before being merged into the repository. If any changes are necessary, the team will leave appropriate comments requesting changes to the code. Unfortunately we cannot guarantee a pull request will be merged, even when modifications are requested, as the Elixir team will re-evaluate the contribution as it changes.
Committers may also push style changes directly to your branch. If you would rather manage all changes yourself, you can disable "Allow edits from maintainers" feature when submitting your pull request.
The Elixir team may optionally assign someone to review a pull request. If someone is assigned, they must explicitly approve the code before another team member can merge it.
When the review finishes, your pull request will be squashed and merged into the repository. If you have carefully organized your commits and believe they should be merged without squashing, please mention it in a comment.
Building the documentation requires ExDocto be installed and built alongside Elixir:
# After cloning and compiling Elixir, in its parent directory: git clone git://github.com/elixir-lang/ex\_doc.git cd ex\_doc && ../elixir/bin/mix do deps.get, compile
Now go back to Elixir's root directory and run:
make docs # to generate HTML pages make docs DOCS\_FORMAT=epub # to generate EPUB documents
This will produce documentation sets for
directory. If you are planning to contribute documentation,please check our best practices for writing documentation.
