Excise

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
pattern_text = 'About {result_count} results'
Excise(pattern_text, 'About 49,000 results') #=> {:result_count=>"49,000"}

# Memoize pattern for performance improvement
pattern = Excise.new(pattern_text)
pattern.parse 'About 49,000,000 results' #=> {:result_count=>"49,000,000"}
pattern.parse 'About 1,000 results' #=> {:result_count=>"1,000"}
