I need to know what's PandocRuby's path to pandoc

[jmuheim]

Hello

On my production server, the most current pandoc version is not the one in the standard path $ pandoc, but in $ /home/www-data/.local/bin/pandoc.

I managed to set PandocRuby to look at the correct place by setting it like so:

PandocRuby.pandoc_path = '/home/www-data/.local/bin/pandoc'

As I need to do some other stuff in my Rails app using Pandoc, I hoped that I could simply do something like this:

def pandoc_version
  matches = `#{PandocRuby.pandoc_path} -v`.match /\bpandoc ((\.?\d+)+)\b/
  pandoc_version = matches[1].to_f
end

But this results in:

undefined method `pandoc_path' for PandocRuby:Class

I managed to work around this now using a global variable:

PANDOC_PATH = '/home/www-data/.local/bin/pandoc'
PandocRuby.pandoc_path = PANDOC_PATH

So I can do:

def pandoc_version
  matches = `#{PANDOC_PATH} -v`.match /\bpandoc ((\.?\d+)+)\b/
  pandoc_version = matches[1].to_f
end

But I'm pretty sure there's an easier way to do this, right?
