Managing Elixir's main branch with asdf

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:

  1. Clone the Elixir code and build it locally:
    git clone /path/to/elixir
    cd /path/to/elixir && make
  2. 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
  3. Verify:
    $ asdf list elixir
  4. 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.
