Hi, I strongly feel that the text processing capabilities with java / groovy power at the command line will definitely be a great feature to the groovy language itself.
Hence my below proposal. If it is felt that the proposal is not going to add value to groovy platform, I will be happy to just delete/move this topic away from the active list...
