Springer et al,
Forgive me for repeating myself, although a lot of interesting ideas, I
believe these to be *non-problems.*
A simple solution is available here. an Example would be an alternate
button to simple permalinks, I think someone else used a share icon. When
clicking this on a given tiddler, it would assign a next number to a field
in the tiddler (basically issuing a unique value field - not a UID or
serial or GUID) then use this field/number to uniquely identify the tiddler
shared, so it does not matter if it's title is renamed. Then generate a url
that instead searches for any (but only one) tiddler with that field value.
If *anyone asks* I will build this share button soon.
That is if someone wants to publish a robust permalink for a tiddler who's
title may change they use a built for purpose alternative to permalinks.
Perhaps the existing name permalinks is misleading, perhaps they should be
impermalinks.
Here is a working example
a tiddler with the "permalink" field=1
the url wiki-url.html#:[permalink[1]]
In the wiki <a href="wiki-url.html#:[permalink[1]]">Open target</a> this
can be dragged to bookmarks/favourites
However I personally choose my tiddler names well enough when needed so
they need not change in future, and if I am publishing a link somewhere it
is to access specific content. the link has a purpose, and once someone has
the link the purpose is fixed in time and should always honour its original
share.
A version of the above method where the link filter
is [has[permalink]last[]] will always link to the largest permalink value,
so one is sharing a link to the latest permalink tiddler or post.
Another supportive trick is to hide the field from the editor with a
tiddler of the form $:/config/EditTemplateFields/Visibility/fieldname
eg $:/config/EditTemplateFields/Visibility/permalink with a value of hide
thus once set you have to go out of your way to alter the permalink value,
that is its more permanent.
Further developments (optional reading)
- Since the addition of the unused title operator, it is possible (more
to the point easier) to use this to generate a unique and incremented
tiddler title and serial number.
- Rather than shadow tiddlers I am using this not only to generate a
tiddler Serial Number (TSN) but a "ghost tiddler" that follows any tiddler
and provides a way to save metadata for any tiddler or field there in
(regardless of the title)
- My only issues left are
- Finding a way to generate/assign such TSN and Ghost tiddler in bulk.
- rebuild a parallel solution - system serial number, to assign a
serial number to core and shadow tiddlers without touching them
- Actually I have found you need only assign serial number where to need
them, say for these permalinks or compound tiddlers, that is with
subtiddlers that use the serial number for the parent rather than the title
or a tag.
Regards
Tones
