About:
Crystalline is a Language Server Protocol (LSP) implementation specifically designed for the Crystal programming language. It provides IDE features like code completion, go-to-definition, and real-time error checking. This tool enhances the development workflow by integrating Crystal's powerful type system directly into editors like VS Code and Neovim.
Key Features:
  • Full Language Server Protocol compliance
  • Real-time type checking and error detection
  • Code navigation (go-to-definition, find references)
  • Intelligent auto-completion and formatting
Use Cases:
  • Developing Crystal applications in VS Code or Neovim
  • Enabling IDE features for Crystal projects
  • Automated code analysis during development
Alternatives:
  • crystal tool format – Built-in tool only handles formatting, whereas Crystalline provides full IDE integration
  • scry – Older LSP implementation; Crystalline is more actively maintained and feature-rich
