gowatch

Go files watcher for Gophers and everyone else.

A tiny Go program that can:

• Run gofmt on saving Go files
• Run a "main" file and restart when it changes.

Install

If you already have your Go workspace and GOPATH set, simply run:

go get -u github.com/sikhapol/gowatch

How to use

Simple

• Run gofmt -w upon saving Go files.
• Run main function when the file is saved.

gowatch

Specify watched directory

gowatch /path/to/watch/

Specify Go file to run

gowatch -r /path/to/main.go

Specify stdin for the run main file

gowatch -i input.txt

Format only

gowatch -n

Delay reporting file change

gowatch -d 5 #seconds

This mean that if a file has changed, gowatch will not take any action if it's changed again within 5 seconds. This is to prevent a loop that cause by gofmt changing the file that cause gowatch to detect change and format the file again and so on. Default is 1 second.

For everything else

gowatch knows if you send input to another command with UNIX pipe. In this case, it will just print the changed file names to stdout which you can then send to another command like xargs to further do anything interesting.

gowatch | xargs cat
