Fresh is a command line tool that builds and (re)starts your web application everytime you save a Go or template file.
If the web framework you are using supports the Fresh runner, it will show build errors on your browser.
It currently works with Traffic, Martini and gocraft/web.
go get github.com/pilu/fresh
cd /path/to/myapp
Start fresh:
fresh
Fresh will watch for file events, and every time you create/modify/delete a file it will build and restart the application.
If go build returns an error, it will log it in the tmp folder.
Traffic already has a middleware that shows the content of that file if it is present. This middleware is automatically added if you run a Traffic web app in dev mode with Fresh.
Check the _examples folder if you want to use it with Martini or Gocraft Web.
It's possible to forward app arguments with -a "-arg 1 -arg 2"
fresh uses ./runner.conf for configuration by default, but you may specify an alternative config filepath using -c:
fresh -c other_runner.conf

root: .
tmp_path: ./tmp

no_rebuild_ext: .tpl, .tmpl, .html

build_delay: 600
