in thread [solved] Test question: how to exercise conditional module load?

Thanks! It didn't work quite perfectly as provided, but it was enough info to get me a working solution:

{ local %INC; delete $INC{YAML.pm}; # make sure YAML isn't loaded $INC{'YAML/Syck.pm'} = 1; # fake loading of YAML::Syck sub YAML::Syck::import { die } require My::Module; ok( $INC{'YAML.pm'}, 'YAML loaded when YAML::Syck not present' ); }

Thanks again!

[ambrus]: The main loop for unixish systems is in https://metacpan. org/source/ KARASIK/Prima-1. 49/unix/apc_app.c. It is a hand-rolled select loop, but also always spins at least once every 0.2 seconds for some reason.
[ambrus]: marto: no, not that way. if you just want to test for an existing id attribute, then write *[@id] , or you can match a regexp to the value of that attribute like *[@id=~/something/ ]
[marto]: ambrus, thanks I ended up going with '//*[starts- with(@id, "thread_")]...
[ambrus]: Sometimes it's easier to just match elements in ways other than xpath, like directly with perl code.
