It may be that I'm simply misunderstanding something, but what is the rationale
tagged() also match normal wikilinks?
It simply hasn't been implemented yet -- see the answer in tag pagespec function. Tags and wikilinks share the same underlying implementation, although ab reasonable expectation is that they are kept separate. --Ivan Z.
The following situation. I have
tagbase => 'tag'. On some pages, scattered
over the whole wiki, I use
[[!tag open_issue_gdb]] to declare that this page
contains information about an open issue with GDB. Then, I have a page
/tag/open_issues_gdb.mdwn that essentially contains
pages="tagged(open_issue_gdb)"]]. So far, so good: this page indeed does list
all pages that are tagged like this. But now, when I add in
/gdb.mdwn a link
to this page, like
[[Open Issues|tag/open_issue_gdb]], then
itself shows up in the map on
tag/open_issues_gdb.mdwn. In my understanding
this is due to the wikilink being equal to a
[[!tag ...]]. What's the
rationale on this, or what am I doing wrong, and how to achieve what I want?
What you are doing "wrong" is putting non-tag pages (i.e.
/tag/open_issues_gdb.mdwn) under your tagbase. The rationale for implementing tag as it has been, I think, is one of simplicity and conciseness. -- Jon
And this is an illustration why a clean work-around (without changing the software) is not possible: while thinking about matching different kinds of links, I thought one could work around the problem by simply explicitly including the kind of the relation into the link target (like the tagbase in tags), and by having a separate page without the "tagbase" to link to when one wants simply to refer to the tag without tagging. But this won't work: one has to at least once refer to the real tag page if one wants to talk about it, and this reference will count as tagging (unwanted). --Ivan Z.
But well, perhaps there is a workaround without introducing different kinds of links. One could modify the tag plugin so that it adds 2 links to a page: for tagging --
tagbase/TAG, and for navigation --
tagdescription/TAG(displayed at the bottom). Then the
tagdescription/TAGpage would hold whatever list one wishes (with
tagged(TAG)in the pagespec), and whenever one wants to merely refer to the tag, one should link to
tagdescription/TAG--this link won't count as tagging. So,
tagbase/TAGwould become completely auxiliary (internal) link targets for ikiwiki, the users would edit or link to only
tagdescription/TAG. --Ivan Z.
