[davido]Does anyone have a copy of 5.8.x running?
[atcroft]davido: AS 5.8.8 on Win7...
[davido]<c>perl -e 'print "Yes\n" if "a" =~ m/\p{ID_Start}/;'
[davido](Just want to know if the property ID_Start was available that far back.
[davido]There's no perluniprops or perlrecharclass for 5.8
[toolic]'Yes' for me
[GotToBTru]'Yes' on 5.8.8 on AIX
[davido]thanks.
[davido]I bet I could look that up somewhere, but some of the POD has been split into other documents in recent years, and I just don't remember where to find it in the old docs.
[davido]http://www.learning-perl.com/2011/07/matching-perl-identifiers-is-a-lot-harder-now/ (Before that I wasn't aware of what properties to use to safely match identifiers)
[davido]And as nick patch points out, that doesn't cover underscore, so it still has to be wrapped in a character class definition.
[RonW]Yikes. that's a lot of regex
[davido]lol.
[RonW]Ok, the conclusion is reasonable
[davido]So matching a package name in isolation should be something like m/\A[\p{ID_Start}_]\p{ID_Continue}?(?:::\p{ID_Continue}+)*\z/
[davido]Oh, change that first ? quantifier to +
[davido]and it might be necessary to have a [\p{ID_Start}_] preceding the final ID_Continue too.
[RonW]Voronich Who's clever plan?
[RonW]The article went on to suggest XID_Start and XID_Continue

↑Previous Hour↑
↓Current Hour↓

[RonW]And yes, after each :: a ID_Start (or XID_Start) will be needed
[Voronich]Project: Complete.
[atcroft]davido: Sorry, that was a "yes" for me as well, AS 5.8.8 on Win7.
[davido]thanks atcroft
