I've got what I hope is a quick question.
I'm trying to port an existing command line API to CLAP-rs, and the current implementation uses a sort of state machine as it parses arguments, such that the flags change what they mean depending on their surrounding flags.
A contrived example would be:
./foobar --file test1 --file-type CSV --file test2 --file-type TSV --file test3 --file test4 --file-type XML
where --file-type is optional (defaults to newline deliminated JSON) and modifies the previous --file argument
So the above example would parse
I thought this might be what "groups" would be used for, but that appears to be a different concept.
Is there a good way to map this sort of API into CLAP-rs? If so, could someone point me to the right part of the documentation to look at? I was contemplating using a custom validator, but that seems pretty hacky, and would assume that CLAP-rs always calls validators in left to right order, which I'm not sure is guaranteed.
