Expert is the official language server implementation for the Elixir programming language.

You can download Expert from the releases page for your operating system and architecture. Put the executable somewhere on your $PATH, like ~/.local/bin/expert

For editor specific installation instructions, please refer to the Installation Instructions

If you want to try out the latest features, you can download a nightly build.

Using the GH CLI, you can run the following command to download the latest nightly build:

gh release download nightly --pattern 'expert_linux_amd64' --repo elixir-lang/expert

Then point your editor to the downloaded binary.

Expert can be built in two ways: building a regular release for your own system(a "plain" release), or building a "burrito" release that works on multiple systems.

To build Expert for your system, run the following command:

just release

You can then point your editor to the start_expert executable in the generated release. You can also run start_expert --help to see available options.

To build Expert using burrito, you need Zig 0.15.2 installed on your system. Later versions will not work.

Then you can run the following command:

just burrito-local

This will build the Expert binary and place it in the apps/expert/burrito_out directory. You can then point your editor to this binary.

You can find more information in the Installation Instructions.
