Description   unfold

This module adds Go support, with optional (but recommended) LSP support via gopls.

• Code completion (gocode)
• Documentation lookup (godoc)
• Eldoc support (go-eldoc)
• REPL (gore)
• Syntax-checking (flycheck)
• Auto-formatting on save (gofmt) (requires doom-module::editor format +onsave)
• Code navigation & refactoring (go-guru)
• File templates
• Snippets
• Generate testing code (go-gen-test)
• Code checking (flycheck-golangci-lint)

Module flags

+lsp

Enable LSP support for go-mode. Requires doom-module::tools lsp and a langserver (supports gopls). Highly recommended, as the non-LSP experience is deprecated (and poor).

+tree-sitter

Leverages tree-sitter for better syntax highlighting and structural text editing. Requires doom-module::tools tree-sitter.

Packages

• doom-package:company-go if doom-module::completion company (DEPRECATED)
• doom-package:flycheck-golangci-lint if doom-module::checkers syntax
• doom-package:go-eldoc
• doom-package:go-gen-test
• doom-package:go-guru
• doom-package:go-mode
• doom-package:gorepl-mode
• doom-package:go-tag
