| 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 176
176: def initialize(args)
177: super
178: @options[:for_engine] = {}
179: 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 250
250: def process_result
251: super
252: @options[:for_engine][:filename] = @options[:filename] if @options[:filename]
253: require File.dirname(__FILE__) + "/../#{@name.downcase}"
254: 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.
@param opts [OptionParser]
# File lib/haml/exec.rb, line 190

191: opts.banner = "Usage: \#{@name.downcase} [options] [INPUT] [OUTPUT]\n\nDescription:\n Uses the \#{@name} engine to parse the specified template\n and outputs the result to the specified file.\n\nOptions:\n"
