How to pass arguments to a javascript file

[iwasa183]

I could run a javascript file named 'highcharts-convert.js' which can generate images of charts on server side.
With original phantomjs command, I just run the command lke below:
%phantomjs highcharts-convert.js -infile option.json -outfile chart.png -scale 4 -width 1000 -constr Chart

I just want to do same thing with phantomjs-gem in ruby program, but I can not find a way to pass arguments, e.g., "-infile option.json -outfile chart.png -scale 4 -width 1000 -constr Chart".

Is it possible to pass arguments to the javascript file with phantomjs-gem?

Looks like the PhantomJs#run takes in multiple arguments.

Something like this should work:

Phantomjs.run('highcharts-convert.js', '-infile option.json', '-outfile chart.png', '-scale 4', '-width 1000', '-constr Chart')

I'm sending params to Run as an array of k=v.

options = {
  infile: 'option.json',
  outfile: 'chart.png',
  scale: 4,
  width: 1000,
  constr: 'Chart'
}.collect { |k, v| "#{k}=#{v}" }

Phantomjs.run('highcharts-conver.js', options)

how do you use the options in the Javscript file?

process.argv is making the script freeze when read.

I personally did it like that:

Phantomjs.run("script.js", "arg1", "arg2")

In script.js:

var system = require('system');
var arg1 = system.args[1];
var arg2 = system.args[2];

@nflorentin This looks more reasonable for my script:

opts = [file, opt1, opt2]
Phantomjs.run(*opts)

Thanks
