Usage:
$ reloader.sh [-e pat] [-d dir] [-h] buildcmd [runcmd]
By default it watches for file system events in the current working
directory. `buildcmd` is the command you want to run (i.e., re-run) each time
a change is detected. `runcmd` is an optional second command to run after the
`buildcmd` completes successfully, for example, compiling a binary and then
running it as a server process.
Options:
-e pat exclude path matching this regex pattern from watch detection
-d dir watch this directory only
Options -e and -d can be given multiple times.
Installation:
Copy it to your $PATH. The file change monitor fswatch[1] is a dependency.
Examples:
