# node-supervisor

A little supervisor script for nodejs. It runs your program, and
watches for code changes, so you can have hot-code reloading-ish
behavior, without worrying about memory leaks and making sure you
clean up all the inter-module references, and without a whole new
`require` system.

## node-supervisor -?


    Node Supervisor is used to restart programs when they crash.
    It can also be used to restart programs when a *.js file changes.

    Usage:
      supervisor [options] <program>
      supervisor [options] -- <program> [args ...]

    Required:
      <program>
        The program to run.

    Options:
      -w|--watch <watchItems>
        A comma-delimited list of folders or js files to watch for changes.
        When a change to a js file occurs, reload the program
        Default is '.'

      -i|--ignore <ignoreItems>
        A comma-delimited list of folders to ignore for changes.
        No default

      --ignore-symlinks
        Ignore symlinks :)
        
      -s|--timestamp
        Log timestamp after each run.
        Make it easy to tell when the task last ran.
        
      -p|--poll-interval <milliseconds>
        How often to poll watched files for changes.
        Defaults to Node default.

      -e|--extensions <extensions>
        A comma-delimited list of file extensions to watch for changes.
        Default is 'node,js' (or when CoffeeScript, 'node,js,coffee,litcoffee').

      -x|--exec <executable>
        The executable that runs the specified program.
        Default is 'node'

      -pid|--save-pid <path>
        Save supervisor's process id to a file at the given path.

      --debug[=port]
        Start node with --debug flag.

      --debug-brk[=port]
        Start node with --debug-brk flag.

      --harmony
        Start node with --harmony flag.

      --inspect
        Start node with --inspect flag.

      -n|--no-restart-on error|exit|success
        Don't automatically restart the supervised program if it ends.
        Supervisor will wait for a change in the source files.
        If "error", an exit code of 0 will still restart.
        If "exit", no restart regardless of exit code.
        If "success", no restart only if exit code is 0.

    -t|--non-interactive
        Dissable interactive capacity
        With this option, supervisor won't listen to stdin

      --force-watch
        Use fs.watch instead of fs.watchFile.
        This may be useful if you see a high cpu load on a windows machine.

	  -k|--instant-kill
	    Instantly kills the server process, instead of gracefully shutting down the server.
		This can be useful when the node app has events attached to SIGTERM or SIGINT so as to do a graceful shutdown before the process exits.
		
     -RV|--restart-verbose
        Logs the file(s) that caused supervisor to restart

      -h|--help|-?
        Display these usage instructions.

      -q|--quiet
        Suppress DEBUG messages


    Options available after start:
      rs - restart process. Useful when you want to restart your program even
           if no file has changed.


    Examples:
      supervisor myapp.js
      supervisor myapp.coffee
      supervisor -w scripts -e myext -x myrunner myapp
      supervisor -w lib,server.js,config.js server.js
      supervisor -- server.js -h host -p port


In order to not watch for file changes, use "-i .".

## Simple Install

Just run:

    npm install supervisor -g

## Fancy Install
