Simple wrapper for the Ghostscript command

GS Ruby

Simple wrapper for the Ghostscript command – it's assumed that you have the gs command installed.

Note: This was developed against version 9.20 of the Ghostscript command and is a work-in-progress. No doubt there are some issues (perhaps even major ones – namespacing, for instance?).

For more detailed documentation, take a look at the source docs – http://www.rubydoc.info/github/lshepstone/gs-ruby

Installation

Add this line to your application's Gemfile:

gem 'gs-ruby'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gs-ruby

Usage

Typical usage might look like:

GS.run('input.ps', GS::OUTPUT_FILE => 'output.pdf')

Or using a block to work with the command before it's run:

GS.run('input.ps') do |command|
  command.option(GS::OUTPUT_FILE, 'output.pdf')
end

Configuration

Global configuration is possible:

GS.configure do |config|
  # ...
end

Logging

By default all output is logged to $stdout, but the logger can be configured:

# For a single command instance.
GS.run('input.ps') do |command|
  # command.logger =
end

# For all command instances.
GS.configure do |config|
  # config.logger =
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
