Elixir for Nova

Editor support for Elixir in Nova. This extension adds syntax highlighting for Elixir along with language server support.

Language Server

The extension can run against either of two language servers, selected in the extension settings under Language Server.

ElixirLS (default)

Bundled with the extension — nothing to install.

Expert (experimental)

This extension has experimental support for the new expert-lsp/expert language server.

To use it:

1. Set Language Server to Expert.
2. Either run the Install Expert Language Server command from the Extensions menu to download the matching binary automatically, or set Expert Binary Path to a binary you've installed yourself (e.g. via the releases page or your package manager).

When the Expert path is left empty, the extension auto-detects an expert (or start_expert) executable in common locations including ~/.local/bin, /opt/homebrew/bin, /usr/local/bin, and its own managed install directory.

Issues

This extension is still under active development. Please report problems at the issue tracker.

Change Log

0.6.0 26 May 2026

Improvements:

• Added experimental support for the Expert language server as an alternative to ElixirLS. ElixirLS remains the default. Select Expert in the extension settings to switch, or run the new Install Expert Language Server command from the Extensions menu to download and install the matching binary automatically.
• Language servers are now launched with the workspace directory as their working directory, so tool-version managers like mise and asdf can detect the project's mise.toml / .tool-versions and activate the right Elixir version.

Fixes:

• Stopped re-registering the Find References command and onDidAddTextEditor listener on every language server restart.
• formatOnSave now takes effect immediately instead of requiring a reload.
