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.
