I've played a lot with the new command line argument handling. Here's a few thoughts: * I think we should not allow the use of raw handler names (e.g. 'eval') and restrict ourselves to flags. For example, disallow 'eval' and stick to '-e' or '--evaluate'. The raw name introduces ambiguity in parsing the command line, especially since custom commands can be added at will that may conflict and see next item... * The current implementation chooses the single matching handler with the highest priority, but usually command line tools may have multiple non-conflicting flags * The priority concept seems premature. It adds complexity and confusion (the handler for a specific flag is not obvious because it emerges from an interaction of all the handlers). Maybe a registry would be better? A dictionary could just map flags to handlers e.g. -e -> EvalHandler, --evaluate -> EvalHandler, etc. Sean -- View this message in context: http://forum.world.st/Command-Line-Handling-tp4612779.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
