julia-lsp

Julia language server plugin for Claude Code, powered by LanguageServer.jl.

Gives Claude Code real-time code intelligence for Julia projects: diagnostics, go-to-definition, find references, hover info, and more.

Prerequisites

Install LanguageServer.jl in your Julia environment. It's recommended to install this in your global Julia environment (e.g. @v1.12).

using Pkg; Pkg.add("LanguageServer")

Usage

claude --plugin-dir /path/to/this/repo

The first LSP request in a session may take 30-60 seconds while Julia JIT-compiles LanguageServer.jl. Subsequent requests are fast.

Configuration

The plugin is configured in .claude-plugin/plugin.json. The startupTimeout is set to 120 seconds to accommodate Julia's JIT compilation. You can adjust this if needed.
