# Rake output customization example | |
# | |
# Rake has two sources of output: | |
# * Rake::FileUtilsExt::rake_output_message | |
# * FileUtils::fu_output_message | |
# | |
# We can customize Rake output by monkey patching these methods. This example | |
# monkey patches these methods to pass the message to our transform_message | |
# method then passing the output to the original output method. | |
def transform_message(*args) | |
prefix = 'rake: ' | |
"\e[%dm%s%s\e[0m" % [1, prefix, args.join(' ')] | |
end | |
