Compile and run your app during development time. Gowatch will automatically build and restart your app on compile and app exit, giving you hot reload like behavior during your dev session.
I wrote this to make things easier on me when I'm iterating and learning to golang, so its pretty bare bones and simplistic.
The file watching is done using fsnotify.
Simply go to your desired directory (for example, $GOPATH/src/myBadassGoProject) and run the following:
gowatch [options] Note: the option that is set on each argument below is the current default if not passed.
-args=""CLI arguments passed to the app
-ignore=[] A comma delimited list of globs for the file watcher to ignore, right now its more like a file extension glob since that's all I really use it for (ie *.html or *.css)
-onexit=true If the app should restart on exit, regardless of exit code
-onerror=true If the app should restart on lint/test/build/non-zero exit code
-wait=1s How long to wait before starting up the build after an exit.
-test=false Should tests be run on reload
-lint=true Should the source be linted on reload
-h|-help Display these usage instructions.
-debug=false Shows debug output, for development use
The linter will not stop the app from running if the lint error has a low confidence value (e.g. for missing package level comments).
Process signals (Interrupt, Kill) are not passed to the child process, I ran into a lot of issues with this but I might figure it out in the near future.
I have not had the chance to test this with multi level packages (e.g. database/sql/driver or net/http) at the moment.
