[ambrus]: was this bug: https://rt.cpan. org/Public/Bug/ Display.html?id= 59814
[Corion]: ambrus: Oh - that one would be much harder to automate... The SYNOPSIS section should mostly be a runnable program IMO, but I write only small snippets in my documentation for single functions/methods, and creating the appropriate environment for ...
[Corion]: ... those in an automated fashion seems somewhat hard to me. Although it should do wonders for the test coverage ;)
[haukex]: Corion: I once wrote an automated thingy for that here
[haukex]: here's the code that uses it
[Corion]: haukex: Hmm - maybe I can reuse that. I see that it uses Pod::Parser, which I think was one of the more fragile parsers. But if I'm statically (re)generating the tests instead of doing that "live" on the client/tester machines, that's a much smaller...
[Corion]: ... problem space than trying to cater to all versions of Pod::Parser(s)
