A memory-bounded LSP server for Go, built for large monorepos.

golance keeps its resident memory independent of workspace size. It indexes the whole workspace once, persists the analysis to disk (content-hash keyed, so editor restarts never re-index), and answers cross-reference queries by reading the on-disk index on demand. While you edit, only the package you are editing is type-checked, with dependencies resolved from export data.

Inspired by rust-glancer's frozen-analysis design, reusing Go's own go/parser + go/types for correctness. Successor to gopls-lazy.

Status: under active development, not yet usable. See plan-feat-v0.1.md.

CI runs golangci-lint run ./... via .github/workflows/lint.yaml (golangci-lint latest, config in .golangci.yaml). To reproduce that locally:

make lint-local

If your go in PATH is a non-release build (e.g. a go1.27-devel custom toolchain), plain golangci-lint run ./... can fail with context loading failed: no go files to analyze, because golangci-lint shells out to go list -json to load packages and that call breaks on devel builds. make lint-local points GOROOT/PATH at a stock SDK for the lint run while leaving your default go untouched. It prefers the toolchain the go command already downloaded for go.mod's go directive (present in the module cache after any build, no network needed) and falls back to installing one through golang.org/dl. See the lint-local target in the Makefile for details.
