Question

Is there a TWikiGroup variable, like %WIKINAME% will display your current user: TWikiGuest.

I would like to use such a variable in combination with the SpreadSheetPlugin in order to hide content on a page from all but certain groups.

If there isn't a %TWIKIGROUP%, or something similar, then how could I go about setting up such a thing?

Thanks

Not yet, if I remember correct.

Okay, well if there is a lack of a %TWIKIGROUP% function then prehaps there is a different way to achieve the results I want.

If I use:

%INCLUDE{MyTopic}%

Yes, that partially works, but when a unprivilaged user logs in they get the error message "No permission to view MyTopic". Which is not ideal. Can we suppress this message?

You could try a %SEARCH% to check whether a user is listed in the desired TWiki group topic. Send the output to a SpreadSheetPlugin variable and test it. Not very helpful, if you have recursive group definitions.

Sounds like a good example for a new TWiki tag.

Nice idea Pankaj.

For now I have used the =

Warning: Can't find topic ""."" = statment and set warn to off, which seems to do the trick, but it's not ideal.

If no-one else has any input then I guess we can close this question off as answered.

%GROUPS% is in releases from 4.0.3 onwards, though it has a known problem (will crash TWiki if there are no groups defined); fixed in 4.1)
