I’ve always used asdf to manage Elixir versions, and I’ve also had a persistent need to run projects or experiments with the latest code from the Elixir repo (main branch). Installing the main branch is quite simple:
- Clone the Elixir code and build it locally:
git clone https://github.com/elixir-lang/elixir.git /path/to/elixir cd /path/to/elixir && make
- Create a symlink in the asdf installs directory and switch to the main version:
ln -s /path/to/elixir ~/.asdf/installs/elixir/main asdf reshim elixir main asdf shell elixir main | asdf global elixir main
$ asdf list elixir 1.15.7-otp-26 1.16.0-otp-26 *main
- Daily update:
cd /path/to/elixir && git pull && make
You can write the above update commands to a script and run it periodically to ensure you’re always using the latest version of the main branch.
- If running make directly throws compilation errors, you need to delete the previous build artifacts before rebuilding:
cd /path/to/elixir make clean && make
- Using the main branch can be somewhat unstable as it’s still under development.
