How do you set slimerjs as the engine for casperjs when using spookyjs?

I'm driving casperjs through spookyjs and I want to use slimerjs, rather than phantomjs, as the engine for casperjs.

When using casperjs you set the engine when calling casperjs from the command line like this:

casperjs *scriptname* --engine=slimerjs

I thought it may be possible to set the engine when configuring casperjs when using spookyjs like this: 

var spooky = new Spooky(
{
  child: {
          transport: 'http'
  },
  casper: {
          logLevel: 'debug',
          verbose: true,
          options: {
            clientScripts: ['public/js/jquery-1.11.1.min.js'],
            engine: 'slimerjs'
          }
  }
},...

But that doesn't work. So how do you use slimerjs as the engine when driving casperjs through spookyjs?

Solution

  • May be this workaround helps. As casperjs is a a python script that sets variables and starts slimmer/phantom, you can just modify the script to make slimmer it's default. Just edit /usr/local/bin/casperjs, and set the engine (around line 86):

    Instead of ENGINE = 'phantomjs' write ENGINE = 'slimerjs'

    Good luck.
