This is a text filter for gsub chain. You can set or replace as many gsub filters as you like, then run them through a given text.
Add this line to your application's Gemfile:
gem 'gsub_filter'
And then execute:
$ bundle
Or install it yourself as:
$ gem install gsub_filter
require "gsub_filter"
gs = GsubFilter.new("ruby is a fantastic language!\nI love ruby.")
# make each words capitalize
gs.filter(/\w+/) {|md| md.to_s.capitalize }
# add asterisks only to the first 'ruby'
gs.filter(/ruby/i, global:false) { |md| "*#{md.to_s}*" }
# a MatchData object passes to the block as its first parameter
gs.filter(/a(.)/) { |md| "a-#{md[1]}" }
# excecute the above filters with run method
gs.run # => "*Ruby* Is A Fa-nta-stic La-ngua-ge!\nI Love Ruby."
GsubFilter#run can take another text for these filters.
gs.run("hello, world of ruby!") # => "Hello, World Of *Ruby*!"
Each filter can be replaced with GsubFilter#replace.
gs.replace(1, /ruby/i) { |md| "###{md.to_s}##" }
gs.run # => "##Ruby## Is A Fa-nta-stic La-ngua-ge!\nI Love ##Ruby##."
The MatchData object can be stocked through the second parameter of the block, which is accessed with GsubFilter#stocks.
gs.filter(/#(\w+)#/) { |md, stocks| stocks[:lang] << md[1]; "+#{md[1]}+" }
gs.run # => "#+Ruby+# Is A Fa-nta-stic La-ngua-ge!\nI Love #+Ruby+#."
gs.stocks # => {:lang=>["Ruby", "Ruby"]}
