go-build

Build, archive and release.

Faster incremental Go builds. gocut is a go build -toolexec wrapper that adds symbol-level early cutoff: when a dependency changes but nothing a package uses from it does, it reuses and patches the old compiled archive instead of recompiling. ~2.7× faster rebuilds on large Go apps, plus a hot-reload watcher (air alternative).

Build go from source

Find out why Go rebuilds everything in CI even with GOCACHE restored. Records a go build or go test run with the go command's cache key inputs, compares two runs, and names what changed: checkout path without -trimpath, Go version, -race, -ldflags, cgo settings, GOROOT, build stamps or source files.

some code snippets for learing go

add $(git describe --tag --dirty) to build

Decide whether a Go source file is part of a build, matching go/build's MatchFile: //go:build and // +build lines, header rules, file-name suffixes and implied tags.
