latex-lsp

LaTeX and BibTeX code intelligence for Claude Code, powered by the texlab language server.

Overview

latex-lsp provides LaTeX and BibTeX language support for Claude Code. It integrates the texlab language server as a Claude Code plugin, enabling code intelligence, diagnostics, and completion directly on LaTeX and BibTeX files.

Features

Language Intelligence

• Completion: commands, citations, labels, and cross-references
• Navigation: go-to-definition, find references, and hover documentation
• Symbols: document outline and workspace-wide symbol search

Diagnostics

• Real-time checks: undefined references, unused BibTeX entries, and syntax errors

Build Integration

• Compile support: texlab coordinates with latexmk / pdflatex for building and error reporting
