I do not have a problem with this semtantic gap, I even already used it, similar to what #TODO does. That case for instance happens when Test::Builder toolchains are not available and it is easier to canonically independently generate the OK/NOTOK part and the directives. > Here's what I would like to see. > > 1..5 > ok 1 - some test > ok 2 - another test > skip 3 - skip cuz I said so > skip 4 - skip, skip, baby > ok 5 -final test > > > In other words, you can't introduce ambiguity here. “NOT OK # SKIP” is no ambiguity. It does not conflict with anything else. It is skipped and semantically being “OK”, same as TODO. The interpretation as SKIP by the TAP::Parser/Aggregator should just be handled the same emotionless, statistic way as TODO: just count how many SKIP, and if you like then also how many of them are unexpectedly OK/NOTOK and left the “semantic strangeness” as exercise to the user. I *strongly* vote *against* introducing a new value additionally to OK/NOT_OK. Especially as it doesn't take away the ambiguity of the “NOT OK # SKIP” case and would be an artificial change introduced without real urge from users (others than the “Wizards Of TAP”). I regularly teach TAP to users and the whole point of it's easyness is the fact I can tell: Basically you either report OK or NOT OK (and a plan). That's all. The rest is just sugar. And I would like to keep the basics and the sugar divided as it currently is: basics on the left side, and the more sugar the more on the right. TAP is KISS: Keep It Simple, Stupid; with emphasis on “keep”. For non-Perl, non-Test::Builder toolchains that easiness is vital! > Though this list is for ietf, those who really care about TAP are > hopefully reading this. I do care for TAP. I use it. I teach it. I build infrastructures around it. Perl and non-Perl. In harmony. Quite. I hope that qualifies my comments a bit. :-) Kind regards, Steffen -- Steffen Schwigon <ss5@renormalist.net>
