Using rails, there are certain folders that require a restart such as anything in config. Also, when developing engines, we ran into some reloading dependency issues which seemed difficult to debug. We decided that a low-memory daemon which restarts whenever certain files are changed would be a good way to manage this issue. This simple script will watch your rails application directory for changes in:
If changes on these paths are detected, the passenger server will be restarted with the command
touch /tmp/restart.txt. You may want to use this script if you are developing plugins or just get tired of restarting when changing initializers or routes.
ruby lib/smart_reloader/daemon.rb PATH_TO_RAILS_APP OPTIONS_LIST
the default options are -l and -c
ruby lib/smart_reloader/daemon.rb ~/apps/my_app -l -c -g
If you are using mac os x, it will smartly observe FSEvent to prevent the need for file polling. If on a linux distribution it will fall back to file polling. If there is a hook on linux, we would like a patch. On mac the notifications will be using growl and growlnotify. If not, the notifications will be directed to stdout.
- Unix-based system (fails on windows)
- Mac OS X >= 10.5 (for FSEvent instead of filesystem polling)
- Growl and growlnotify (only if on mac)
Thanks to Sven Schwyn for the fsevent handling he created for his awesome project autotest-mac. Thanks to autotest for giving us the inspiration to create this daemon.
