How can I start Hubot using strong-pm?

[bossyang]

Every hubot install has a bin/hubot script to handle starting up the hubot. Currently I use PM2 to manage the server process. Is there anyway porting this to strong-pm?

[sam-github]

strong-pm will run the first found of these: https://github.com/strongloop/strong-supervisor/blob/master/bin/sl-run.txt#L5-L11

Creating a server.js in the root of your package that looked like:

require('./bin/hubot')

would probably work. Test it by running your hubot with slc run . in the root of your package, and see if it runs. If it does, pm can use run it.

[bossyang]

No, it doesn't work.

Have you looked at bin/hubot? Its not javascript, its some kind of shell script, that apparently runs npm install, and then, I assume, runs the actual application main. Shell scripts can't be required by node.

What, exactly, is the main _node javascript_ file for your bot?

[bossyang]

Yes, bin/hubot is a shell script. It runs another shell script via node. The file is generated by hubot yeoman generator. I just put my bot scripts under scripts folder. With PM2, I need set interpreter to bash.

bin/hubot

#!/bin/sh

set -e

npm install
export PATH="node_modules/.bin:node_modules/hubot/node_modules/.bin:$PATH"

exec node_modules/.bin/hubot --name "jbot" "$@"

node_modules/hubot/bin/hubot

#!/usr/bin/env coffee
# vim:ft=coffee ts=2 sw=2 et :
# -*- mode:coffee -*-

Hubot    = require '..'

Fs       = require 'fs'
OptParse = require 'optparse'
Path     = require 'path'

[sam-github]

strong-pm injects instrumentation into node before passing control to your javascript: it must run javascript, not bash.

If you have a js file you can run as your main, you can use strong-pm, but if your node app only runs with a shell script wrapper, I don't thin pm will work for you.

@sam-github Thanks.
