ElixirLS is a language server for Elixir implementing the Language Server Protocol, providing IDE features like completion, go-to-definition, formatting, and Dialyzer-based analysis. It also includes a debug adapter implementing the Debug Adapter Protocol for step-through debugging of Elixir projects.

Use cases

• get autocomplete and go-to-definition for Elixir in my editor
• run the Elixir compiler and see errors inline in my IDE
• integrate Dialyzer static analysis into my editor
• debug Elixir applications with breakpoints in VS Code
• format Elixir code automatically on save
• find all references to a function across a Mix project

When to choose

• you write Elixir and want IDE features in any LSP-compatible editor
• you need step-through debugging for Elixir via DAP
• you want incremental Dialyzer analysis and inline warnings

When to avoid

• your editor has no LSP client support
• you only need syntax highlighting without code intelligence
• you work primarily with Erlang rather than Elixir
