Background

Claude Code v2.0.76 has a bug (#13952) where LSP servers from plugins fail to load. The initialize function in the LSP server manager is empty and does nothing.

This repository provides:

1. A patch script to fix the LSP loading bug
2. A plugin marketplace with custom plugins (starting with Crystal language support)

Install

LSP Patch

git clone https://github.com/watzon/claude-code
cd claude-code
chmod +x lsp-patch.sh
./lsp-patch.sh

Plugin Marketplace

Add to your Claude Code settings (~/.claude/settings.json):

{
  "pluginMarketplaces": [
    "https://github.com/watzon/claude-code"
  ]
}

Then install plugins:

/plugin install crystal-lsp@watzon-marketplace

Usage

LSP Patch

# Check if patch is needed/applied
./lsp-patch.sh --check

# Apply the patch
./lsp-patch.sh

# Restore original (if needed)
./lsp-patch.sh --restore

The script auto-detects Claude Code installations:

• Bun global (~/.bun/install/global/...)
• Native (~/.claude/local/...)
• npm global (/usr/local/lib/node_modules/...)
• fnm/nvm managed Node versions

Note: The patch is overwritten when Claude Code updates. Re-run after updates if LSP stops working.

Plugin Marketplace

After adding the marketplace to settings, use /plugin in Claude Code to browse and install plugins.
