Parent: | Generic |
An abstrac class that encapsulates the code specific to the `haml` and `sass` executables.
@param args [Array<String>] The command-line arguments
# File lib/haml/exec.rb, line 116 116: def initialize(args) 117: super 118: @options[:for_engine] = {} 119: end
Processes the options set by the command-line arguments. In particular, sets `@options[:for_engine][:filename]` to the input filename and requires the appropriate file.
This is meant to be overridden by subclasses so they can run their respective programs.
# File lib/haml/exec.rb, line 191 191: def process_result 192: super 193: @options[:for_engine][:filename] = @options[:filename] if @options[:filename] 194: require File.dirname(__FILE__) + "/../#{@name.downcase}" 195: end
Tells optparse how to parse the arguments available for the `haml` and `sass` executables.
This is meant to be overridden by subclasses so they can add their own options.
