Watch your files and run your programs.

watchrun is a command-line utility to monitor a directory and run a command when any file in that directory changes. It excludes temporary and hidden files that start with . or ~ or end with ~.

To install from source:

go get github.com/loov/watchrun

Example usage:

$ watchrun go run main.go

Then you can test with:

$ echo package main; main(){ println("hello") } > main.go
$ echo package main; main(){ println("world") } > main.go

You can explicitly specify which folder or file to watch with -monitor:

$ watchrun -monitor ../../ go run main.go
$ watchrun -monitor main.go go run main.go

You can run multiple commands in succession with == (instead of the usual &&). For example:

$ watchrun go build -i . == myproject
