Excise Build Status Code Climate

This is a simple helper to extract values from a string based on a pattern.

A Ruby port of laktek's extract-values.

Installation

Add this line to your application's Gemfile:

gem 'excise'

And then execute:

$ bundle

Or install it yourself as:

$ gem install excise

Usage

require 'excise'

# Basic use
Excise('About {result_count} results ({load_time} seconds)',
       'About 49,000,000 results (0.15 seconds)')
#=> {:result_count=>"49,000,000", :load_time=>"0.15"}

# Memoize pattern for performance improvement
pattern = Excise.new('[{key}]')
pattern.parse '[value]' #=> {:key=>"value"}
pattern.parse '[other]' #=> {:key=>"other"}
