I've added this for 2.2.121 (you can get the pre-release as a ZIP file
or from Subversion here:
https://www.pmwiki.org/wiki/PmWiki/Subversion
Only pmwiki.php was modified for this feature since 2.2.120.
The documentation for this is here:
https://www.pmwiki.org/wiki/PmWiki/PageTextVariables#default
Note that it doesn't distinguish "var not defined in page" from "user
has no permissions for page". But if you *know* that a specific variable
*is* defined in a specific protected page and it looks like unset, then
the user doesn't have read permissions.
For example, in config.php:
$DefaultUnsetPageTextVars['AdminTasks'] =
'[[SiteAdmin.Tasks?action=login|login to see your tasks]]';
then e.g. in Site.SideBar:
{SiteAdmin.Tasks$:AdminTasks}
With earlier PmWiki versions you could use a conditional:
(:if auth read SiteAdmin.Tasks:)
{SiteAdmin.Tasks$:AdminTasks}
(:else:)
[[SiteAdmin.Tasks?action=login|login to see your tasks]]
(:ifend:)
If the value is a single line without quotes, you could alternatively
use:
(:if equal "" "{SiteAdmin.Tasks$:AdminTasks}":)
(no permissions)
(:ifend:)

Is there a way to have a "default" markup for an unknown or empty page
text variable?
Specifically, might be nice for "something" to show up for a PTV for
which somebody can't access because of permissions, but I'm ok with
some sort of general case. Possible?
I'm ok with enabling such via special per group/page php.
But doesn't seem possible at all today? Like a
PCache[pagename]["=p_<whatever>] default set in PageTextVar even for
situations where the PCache can't be fetched due to permissions.
Something like that.
