Subject: [UNI] Regex Unicode properties check values before checking property names
Download (untitled) / with headers

See test in properties-general.t The test used to pass before, but only because 'space' resolved to Unicode Property 'LF'='space'. Since https://github.com/MoarVM/MoarVM/commit/ 5f1e081bad4a4846f2e7a0681af60450e82155c8 or one the commits right before it, this is broken because space no longer means LF=space. #?rakudo.moar TODO "Possible bug in NQP where <:space> does not match, because it checks property VALUES before checking Bool property names"

say ' ' ~~ /<:space>/; #> Nil Should return spaces instead. Checking this works fine though: ' '.uniprop-bool('space') #> True

Also see this bisectable results: https://gist.github.com/Whateverable/50acf5fe072680085746459f144a106f You can see how with the new commit, 'space' and 'White_Space' now resolve to the same property. Before 'space' resolved to the LF property, and magically worked. When this was fixed and 'space' == 'White_Space', it broke. This bug will be considered close when: use nqp; say nqp::unipropcode('space') == nqp::unipropcode('White_Space') #> True and also must work doing: `' ' ~~ /<:space>/; #> 「 」`
