Some SVG optimization based on Node's SVGO

SvgOptimizer

Some small optimizations for SVG files.

Installation

Add this line to your application's Gemfile:

gem 'svg_optimizer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install svg_optimizer

Usage

# Optimize an existing String.
xml = File.read("file.svg")
optimized = SvgOptimizer.optimize(xml)

# Optimize a file - it will override the original file.
SvgOptimizer.optimize_file("file.svg")

# Optimize a file - it saves a copy to "optimized/file.svg".
SvgOptimizer.optimize_file("file.svg", "optimized/file.svg")

You can specify the plugins you want to enable. The method signature is:

SvgOptimizer.optimize(xml, plugins)
SvgOptimizer.optimize_file(input, output, plugins)

where plugins is an array of classes that implement the following contract:

class MyPlugin < SvgOptimizer::Plugins::Base
  def process
    xml.xpath("//comment()").remove
  end
end

The default list of plugins is stored at SvgOptimizer::DEFAULT_PLUGINS. To use your new plugin, just do something like this:

SvgOptimizer.optimize(xml, SvgOptimizer::DEFAULT_PLUGINS + [MyPlugin])
