crun - continuously Compile and Run

Crun is a command line tool that compiles and runs your go code and watches all .go files in the current directory, recompiling and rerunning your code when the files change.

Useful to start webapps and recompiling them each time a file changes. As such it is an alternative to go run server.go, each time terminating the command yourself and doing go run server.go again.

Install

Ensure Go is installed and your GOPATH set.

Install package:

go get github.com/toonketels/crun
