[pmwiki-devel] underscores in group names

[Ben Stallings]

Happy New Year, everybody!  Hope you're not down with the stomach flu 
like I have been for the past 3 days.  At least I was able to get out of 
the house today, but a party is out of the question. :-(

Marc brought up an interesting flaw in my DataQuery approach a few days 
ago... it's a common practice to use underscores in the names of 
database tables, for example `demo_table`.  Part of the whole point of 
DataQuery is to use table names as group names, but when you type, for 
instance, [[demo_table.12]] PmWiki creates a link to DemoTable.12 instead.

I see the discussion in Cookbook/AlternateNamingScheme about how to get 
PmWiki to use underscores instead of spaces, but I'm more interested in 
getting it to leave underscores alone... is this just a question of 
adding '_' to $PageNameChars, or does that only affect page names and 
not group names?  Would tampering with $PageNameChars have unfortunate 
consequences for other scripts?

While I'm at it... another problem I've been running into with this 
approach is that table names are rarely capitalized in the CamelCaps 
that PmWiki favors.  I've been circumventing this so far by using 
strtolower() on all names before comparing them, but that's kind of 
shooting from the hip.  Is there a better, more precise way I should 
know about, like perhaps a PmWiki function that's designed for that very 
purpose?

Thanks, and best wishes for a year of health and creativity!  --Ben
