Question

I built this using TopicVarsPlugin:

| *Web* | *VIEW* || *CHANGE* || *RENAME* ||
|  | *DENY* | *ALLOW* | *DENY* | *ALLOW* | *DENY* | *ALLOW* |
%WEBLIST{format="| [[$name.WebHome][$name]] [[$name.WebPreferences][...]] | %$name.WebPreferences.DENYWEBVIEW% | %$name.WebPreferences.ALLOWWEBVIEW% | %$name.WebPreferences.ALLOWWEBCHANGE% | %$name.WebPreferences.DENYWEBCHANGE% | %$name.WebPreferences.DENYWEBRENAME% | %$name.WebPreferences.ALLOWWEBVIEW% |" webs="public"}%

Because this does not work:

%WEBLIST{format="| [[$name.WebHome][$name]] [[$name.WebPreferences][...]] | %VAR{$quotDENYWEBVIEW$quot web=$qname}% |" webs="public"}%

and neither does this:

%WEBLIST{format="| [[$name.WebHome][$name]] [[$name.WebPreferences][...]] | %VAR{"DENYWEBVIEW" web=$qname}% |" webs="public"}%

Clearly it breaks because of the quotes. SEARCH has a cumbersome $quot syntax and AttrsContrib allows different or no quotes at all.

Am I missing something, is it not possible to use the current implementation to do this without the search like the one on SiteMap?

Answer

WEBLIST does not offer the vars SEARCH does (such as $quot and $percnt). That is, you can't use WEBLIST be because you can't delay the evaluation of VAR, which needs to be done for each web.

Use SEARCH instead. There are two ways to get at the variables in the format="" parameter:

1. pattern that extracts the parameter: $pattern(.*?\* Set ALLOWWEBRENAME\s*=([^\n\r]*).*)
2. delayed VAR that executes for each hit: $percntVAR{ \"ALLOWWEBRENAME\" web=\"$web\" }$percnt

This demo example does both, first rows with pattern, last row with VAR:

Thanks Peter.

I can't help but think that the TopicVarsPlugin syntax is much more intuitive, and after that any user would attempt to use WEBLIST. Hell, I gave up - what are newbies going to do?

Any reason why we shouldn't incorporate the TopicVarsPlugin syntax into the core?

Doing a SEARCH for the set command is IMO asking for trouble, whereas the percntVAR is just ugly.

I've published this as TWiki.SitePermissions in the hope that it is useful. This continues the TWiki.org Codev.TopicNamingStandards of naming site-topics Site*.
