[Gretl-devel] Re: tobit's --quiet flag to quite guiet

So, the question is: shall we leave current behavior or make 'tobit --quiet' really quiet? If the later, I wrote a simple patch which suppress any messages (attached). Another possibility would be adding '--silent' flag, which I could do either? Personally I think that choosing "quiet" doesn't mean that I don't want to see warning messages, so the current behavior is OK. "silent" could be a possibility, but then I think we would have to do it for all estimators, not just for tobit out of coincidence. Right now I think the guideline is more or less that "silent" exists for tests and for system estimation (where even quiet prints a little bit of regular output). I believe there's a workaround to really suppress all output: Wrap it in an "outfile" block: string temp outfile --buffer=temp tobit ... outfile end And simply discard the string. Admittedly not very elegant...
