gow

gow [flags] command [args]

gow ("go watch") is invoked exactly like go, but additionally watches the Go source tree and reruns the given command whenever a watched file changes. It wraps go run, go test, go build, and other subcommands transparently, ignoring non-Go files by default.It uses a recursive, event-driven watcher (no polling) so restarts are near-instant, clears leftover output between runs, and supports hotkeys such as ctrl+r to force a restart.

COMMAND

Any go subcommand to wrap and re-run (run, test, build, vet, ...).

Clear the terminal before each restart.

File extensions to watch. Default: go.

Verbose output, printing what triggered each restart.

Display help information.

Development tool only; not intended for production process supervision. Watches recursively from the current directory by default.

gow was created by Nelo Mitranim as a lightweight replacement for his earlier gorun tool, adding a better file watcher and hotkey support for Go development workflows.
