Goup

Watches and restarts go applications on source code changes.

go get github.com/DATA-DOG/goup

Main features:

  • just run goup where your main package is.
  • forwards stdin and all command line arguments.
  • goup itself has no options.
  • does not use go build but rather go install which increases restart performance dramatically.
  • can watch applications outside $GOPATH run it like GOBIN=$GOPATH/bin goup -my-cmd-option args < stdin or export $GOBIN
  • tracks all dependent non $GOROOT packages, including all in $GOPATH, except in vendor directories.
  • restarts only if go install was successful, so you do not have failed state.
  • is about 200 loc simple to copy and adapt to your custom needs.
