Re: [tap] "ok 1 description" vs "ok 1 - description"

Sorry for the late answer, I seem to be out of sync with the rest of
the world ...

They are created within a heterogeneous environment with Perl
Test::More, Python PyTAP, and "echo/print" from Shell or C.

To process the TAP, however, we use the Perl toolchain around
TAP::Parser.

I see that the dash was meant optional for TAP. Maybe the
optionality of the dash changed in TAP::Parser 3? Admittedly, I
didn't try.

Anyway, the only useful current processing tool is TAP::Parser and
that slurps the dash as part of the description.

So it's probably not the producers like Test::*, PyTAP and
"print" but the history of the *consumer*, i.e. TAP::Parser,
that I'm worrying about.

Someone(tm) (not me, I know, sorry) could try out what happens
around CPAN (as the largest reference test suite) if the grammar is
changed in TAP::Parser.

I see. But wasn't the original plan to write down what the only
existing consumer toolchain aka. TAP::Parser does, because else no
one in the world has a toolchain?


Kind regards,
