Jetbrains Elixir Today

While Elixir LS in VS Code is excellent, JetBrains Elixir offers a different, often more thorough experience. JetBrains Elixir VS Code + ElixirLS Deep indexing for fast search/nav Good, but can be slow on large projects Refactoring Advanced, safe automated refactoring Basic, mostly via LSP Debugging Strong, graphical debugger Very good, but setup can be complex Memory Usage Higher (JVM based) Cost Paid (Ultimate) or Free (Community) Conclusion

JetBrains IDEs, such as , are known for their deep understanding of code structure. When applied to Elixir, this means going beyond simple syntax highlighting. jetbrains elixir

| Feature | IntelliJ Elixir (v2023.3+) | VS Code + ElixirLS (v0.14) | |---------|----------------------------|----------------------------| | | Contextual, includes local/calls/macros | Comparable, uses Elixir’s code:get_env | | Go to definition | Works for most functions, fails on dynamic dispatch | Similar, but macro expansion via --trace | | Find usages | Excellent, includes usages across umbrella apps | Good, but slower in large repos | | Refactoring | Rename, extract function, inline variable – safe rename works across modules | Very limited (only rename via LSP, no extract) | | Structural Search & Replace | Yes (IntelliJ ultimate feature) – search AST patterns | No | | Quick fixes | Add missing alias, import, generate defimpl | Add alias, generate callback stubs | | Debugging | Works but requires setup; variable inspection can be flaky | ElixirLS debugger via elixir-ls/debugger – more stable | | Performance (large project) | Heavy memory (~2-3GB); indexing can stall | Lighter; incremental updates faster | | Price | Free plugin (IntelliJ Community Edition works) | Free (VS Code free) | Run ExUnit tests directly from the editor, with
