Compile and reload your package in Go lang

One of the Go lang goodness is the blazing fast compiler (can you hear me Scala? :P), that can give you the productivity of a interpreted language. But to be, productive in the same way, at least building Web services, you need get rid of the recompile and kill/reload cycle for your application.

I tried a couple of utils to do that, and the most simple that it works is rerun You can just clone the repository, do a ‘go install’ and add the binary to your PATH variable.

And now with a simple:

rerun --test

I have my webserver running, and every time that I make a change in the code, the test are passed again, and the server is reload. I know, right now my server It’s very light and It does that in milliseconds, but I’m sure it’s not going to reach the start time of any Java application :)
