Since getting my Forgeojo dev environment running I've begun poking around the issue backlog and learning my way around the code, looking for the stepping stones to becoming a contributor. One important early milestone was to get the Golang LSP running in Helix.
You can always check if Helix's LSP integration for a given language is ready by
using hx --health.
$ hx --health go Configured language servers: ✘ gopls: 'gopls' not found in $PATH ✘ golangci-lint-lsp: 'golangci-lint-langserver' not found in $PATH Configured debug adapter: ✘ 'dlv' not found in $PATH Configured formatter: None Tree-sitter parser: ✓ Highlight queries: ✓ Textobject queries: ✓ Indent queries: ✓
Those ✘ symbols are bad news! Installing those missing tools looked like this.
go install golang.org/x/tools/gopls@latest go install github.com/nametake/golangci-lint-langserver@latest go install github.com/go-delve/delve/cmd/dlv@latest brew install golangci-lint
That last brew install there is good to know about. You'll get ✓✓✓ from
hx --health without it, but linting won't actually work, and instead there's
an error about exec: "golangci-lint": executable not found in $PATH.
Then there was one last little trick necessary. Those things that go install
downloaded live in ~/go/bin, which isn't in $PATH. I threw a Fish plugin at
the problem, like this.
fisher install halostatue/fish-go@v2
After that, I had ✓ across the board.
$ hx --health go Configured language servers: ✓ gopls: /Users/henrycatalinismith/go/bin/gopls ✓ golangci-lint-lsp: /Users/henrycatalinismith/go/bin/golangci-lint-langserver Configured debug adapter: ✓ /Users/henrycatalinismith/go/bin/dlv Configured formatter: None Tree-sitter parser: ✓ Highlight queries: ✓ Textobject queries: ✓ Indent queries: ✓
Here's Helix in action with the tooling integrated, successfully detecting a linter error resulting from an unused variable.
