Fuzzy finder

[theonlygusti]

Is it possible to make all option names use a fuzzy finder?

E.g. I define

@Parameter(names = "rename", arity = 2)

private List<String> rename;

And then I'd be able to call the program <main> with all of these command line options

<main> rename potato tomato

<main> ren potato tomato

<main> rme potato tomato

to accomplish the same things.

How would I be able to implement this using JCommander? Is it indeed possible?

Not possible at the moment but it should be pretty easy to add a special fuzzy mode to JCommander. The main difference would be that instead of getting the key from a map, you'd extract all the existing keys and do a substring match on them (assuming that's what you mean by fuzzy).

Not convinced it's really that useful but it can be done in a backward compatible way (you'd have to configure your JCommander object to work in fuzzy mode before parsing), so I'm not opposed to it.

Using the current JCommander, is there an efficient way for me to
implement this in my own project? Or would I have to convert all the
options myself before passing them to JCommander? (Which honestly
almost defeats its purpose :P)

JCommander doesn't have support for plug-ins, so no, short of sending a pull request to modify it, there is no way to add this functionality to it right now.

I've wondered a few times about adding plug-ins to JCommander but this has always struck me as overkill for a simple command line parsing library.

Are plugins really ever overkill though? I think everyone respects
bare-bones but extendable libraries.

I'll look into the code though, it's really something I'd like to be
able to use.
