Language Server Protocol

The Bear LSP server provides editor intelligence: autocompletion, diagnostics, go-to-definition, find references, hover info, and more.

# Install the language server
$ git clone --depth=1 https://github.com/bearlanguageorg/bear
$ bear install --lsp

# Or download the latest binary directly
$ curl -sL https://github.com/bearlanguageorg/bear/releases/download/0.0.1-rew1.0/bear-lsp-0.0.1-rew1.0 -o bear-lsp
$ chmod +x bear-lsp
$ ./bear-lsp

Autocomplete

Context-aware suggestions for functions, types, keywords, and imported symbols.

Diagnostics

Real-time error and warning highlighting as you type, with actionable messages.
