We have several jira issues related to gfsh parsing (GEODE-1598, GEODE-1912). After spending some time understanding how the parsing works, I found out we have three components intertwined together all trying to do parsing: Gfsh, JoptSimple and Spring Shell. I started an experiment by getting rid of Gfsh and JoptSimple parsing and only using Spring Shell. The outcome is I am able to maintain the current parsing and tabbing completion capabilities (and fix a few bugs) by removing 40+ files. The only difference I see so far lies in the help and hint messages. It seems the main reason we are using these home backed Gfsh parsing is to provide more readable help messages. Below are the differences:
Using Spring Shell's provided help: Using Gfsh Parsing with JoptSimple: I do like the outcome of the latter, but added complexity of the code is too expensive to bear. So I am asking the community how important it is to maintain the current style of help? Can we do with the cheaper way by just using whatever provided by the libraries? -- Cheers Jinmei
