module Gennifer

TODO: write a lot richer default recipe (at least it should support more file extension names) TODO: better advide when gennifer is installed but there is no settings file (or the settings files is not in the correct format) TODO: show help text or show better instructions (instead of ‘recipe not found“) when gen is run but no recipe is matached. (presumably this is the case of typo or wrong syntax) TODO: consider adding convention such as underscore before project type TODO: make the arguments available to the receipe as a hash. So that one can use erb to get the argument and generate more complicated files. TODO: better ”bin recipe“, moving the file to bin folder after create mey not be the best solution because it handle duplicate files poorly (or I can improve the afterrecipe to take into accoount those situation, or may a helper method)
