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 build -o example.exe . == ./example.exe"
Note: directly using watchrun go run main.go, doesn't kill the compiled program automatically, which may cause problems, if you have a server listening.
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 build -o example.exe . == ./example.exe"
$ watchrun -monitor main.go "go build -o example.exe . == ./example.exe"
You can run multiple commands in succession with == (instead of the usual &&). For example:
$ watchrun go build -i . == myproject
Usage of watchrun:
-ignore string
ignore files/folders that match these globs (default "~*;.*;*~;*.exe")
-interval duration
interval to wait between monitoring (default 300ms)
-monitor string
files/folders/globs to monitor (default ".")
-recurse
when watching a folder should recurse (default true)
-verbose
verbose output
