## What it is
Solargraph is a Ruby language server implementing the Language Server Protocol, providing intellisense, context-aware autocompletion, inline documentation, diagnostics, and type checking. It is distributed as a Ruby gem and integrates with editors like VS Code, Vim, Emacs, Sublime Text, and Eclipse.

## Use cases
- get autocomplete for ruby in vscode
- add intellisense to my ruby editor
- type check ruby code in the editor
- show inline documentation for ruby gems
- lint and diagnose ruby files via lsp
- set up a ruby language server for neovim

## When to choose
- you write Ruby and want IDE-like completion, hover docs, and diagnostics in your editor
- you need an LSP server for Ruby that works across many editors
- you want gem documentation and core Ruby docs integrated with autocomplete

## When to avoid
- you need deep Rails-specific support without adding the separate solargraph-rails plugin
- you need full static type checking comparable to Sorbet or Steep
- your project is not Ruby

## Facets
- artifact type: library
- maturity: active
- function: editor, developer-tools, documentation, linter, type-system
- domain: developer-tools, programming-languages, text-editors
- platform: cross-platform, editor-plugin, cli
- tags: ruby, language-server-protocol, intellisense, autocomplete, static-analysis, lsp
