deepseekcode

LSP Client

deepseekcode integrates with Language Server Protocol (LSP) servers to provide IDE-like code intelligence from the terminal.

Supported Languages

Language	Server	Detection File
Go	gopls	go.mod
Rust	rust-analyzer	Cargo.toml
TypeScript/JavaScript	typescript-language-server	tsconfig.json
Python	pylsp	pyproject.toml or requirements.txt

How It Works

1. On startup, deepseekcode scans the project directory for language detection files.
2. For each detected language, it spawns the corresponding LSP server via stdio.
3. The lsp tool is registered and can be called by the model or via slash commands.

The lsp Tool

Parameters:

• action (required): One of hover, definition, references, diagnostics
• file (required): File path to query
• line (optional): 1-indexed line number (for hover, definition, references)
• character (optional): 1-indexed character offset (for hover, definition, references)

Actions

hover — Show type information and documentation at a position. definition — Find where the symbol at a position is defined. references — Find all references to the symbol at a position. diagnostics — Show compiler/linter errors and warnings for a file.

Requirements

• The LSP server binary must be installed and in PATH.
• Install with:
  • go install golang.org/x/tools/gopls@latest
  • rustup component add rust-analyzer
  • npm install -g typescript-language-server typescript
  • pip install python-lsp-server

Doctor Check

Run dsc doctor to see which LSP servers are detected for the current project:

deepseekcode doctor
──────────────────────────────────────────────────
  ✓ lsp                 available: gopls

If no language servers are detected, the check shows:

  ✓ lsp                 no language servers detected for this project
