lsp-gateway/config.yaml

Local LSP gateway for development - HTTP JSON-RPC and MCP server for 4 languages

# Default Configuration for LSP Gateway
# Simplified CLI with basic LSP server integration for all supported languages

servers:
  # Go Language Server
  go:
    command: "gopls"
    args: ["serve"]
    working_dir: ""
    initialization_options: {}

  # Python Language Server  
  python:
    command: "pylsp"
    args: []
    working_dir: ""
    initialization_options: {}

  # JavaScript Language Server
  javascript:
    command: "typescript-language-server"
    args: ["--stdio"]
    working_dir: ""
    initialization_options: {}

  # TypeScript Language Server
  typescript:
    command: "typescript-language-server"
    args: ["--stdio"]
    working_dir: ""
    initialization_options: {}

  # Java Language Server
  java:
    command: "jdtls"
    args: []
    working_dir: ""
    initialization_options: {}

# Unified Cache Configuration (Enabled by default)  
# Standard production settings with simple units for improved performance
cache:
  enabled: true                               # Enabled by default for improved performance
  storage_path: ".lsp-gateway/cache"          # Cache storage directory (relative to project root)
  max_memory_mb: 256                          # Memory limit in MB (simple units)
  ttl_hours: 24                               # Cache time-to-live in hours (simple units - 24h for daily dev workflow)
  languages: ["go", "python", "typescript", "java"]  # Languages to cache
  background_index: true                      # Enable background indexing for better performance
  health_check_minutes: 5                     # Health check interval in minutes (simple units)
  eviction_policy: "lru"                      # Cache eviction policy (lru, simple)
  disk_cache: false                           # Enable disk persistence (false for in-memory only)

# Cache Configuration Notes:
#
# 1. Performance & Safety:
#    - Cache is ENABLED by default for improved performance
#    - Set 'enabled: false' to disable if needed
#    - Validates memory limits against system resources
#
# 2. Storage:
#    - storage_path is relative to project root or absolute path
#    - Directory will be created automatically if it doesn't exist
#    - Ensure sufficient disk space for cache storage
#
# 3. Memory Management:
#    - max_memory_mb should be reasonable for your system
#    - System will warn if > 50% of available memory
#    - Consider other applications when setting limits
#
# 4. Performance Tuning:
#    - ttl_hours: 24 hours TTL optimized for daily development workflow (simple units)
#    - background_index: Enable for better responsiveness
#    - health_check_minutes: 5 minutes to monitor cache health periodically (simple units)
#    - eviction_policy: LRU for intelligent cache management
#
# 5. Language Support:
#    - Only supported languages: go, python, javascript, typescript, java
#    - Cache works best with languages that have stable symbol information
#    - Remove languages you don't use to save resources
