just to make sure.
I understand about the backslashes and special PmWiki variable $FullName
^ ^ ^
uses double quotes with backslash $Special_PmWiki_variable($FullName)
is the same as
^ ^ ^
uses single quote nobackslash $Special_PmWiki_variable($FullName)
Is there any reason to use one and not the other?
But I don't understand how ("$FarmD and ('$FarmD are, or are not, the same
$WikiLibDirs = array(&$WikiDir,
1) new PageStore("$FarmD/wiki.d/\$FullName"),
2) new PageStore("$FarmD/shared.d/\$FullName"),
3) new PageStore('$FarmD/wikilib.d/$FullName'));
Shouldn't line 3) be
3) new PageStore("$FarmD/wikilib.d/\$FullName"));
I know... Confusing as heck
