The IkiWiki::pagetitle function does not respect title changes via meta.title. It really should, so that links rendered with htmllink get the proper title in the link text.

It is possible to set a Page-Title in the meta-plugin, but that one isn't
reused in parentlinks. This [[patch]] may fix it.
A few quick notes about it:
- Using inline would avoid the redefinition + code duplication.
- A few plugins would need to be upgraded.
- It may be necessary to adapt the testsuite in
t/pagetitle.t, as well.

It was actually more complicated than expected. A working prototype is
now in my meta branch, see my userpage for the up-to-date url.
Thus tagging [[patch]]. --[[intrigeri]]
Joey, please consider merging my meta branch. --[[intrigeri]]
So, looking at your meta branch: --[[Joey]]
- Inter-page dependencies. If page A links to page B, and page B currently
has no title, then A will display the link as "B". Now page B is modified
and a title is added. Nothing updates "A".
The added overhead of rebuilding every page that links to B when B is
changed (as the
postscan hook of the po plugin does) is IMHO a killer.
That could be hundreds or thousands of pages, making interactive editing
way slow. This is probably the main reason I had not attempted this whole
thing myself. IMHO this calls for some kind of intellegent dependency
handler that can detect when B's title has changed and only rebuild pages
that link to B in that case.
- Looks like some plugins that use
pagetitle to format it for display
were not changed to use nicepagetitle (for example, rename).
But most of those callers intend to display the page name
as a title, but including the parent directories in the path. (Ie,
"renaming foo/page title to bar/page title" --
you want to know it's moved from foo to bar.) nicepagetitle does not
allow doing that since it always takes the basename.
- I don't like the name
nicepagetitle. It's not very descriptive, is it?
And it seems very confusing to choose whether to use the "nice" or original
version. My hope is that adding a second function is unnecessary.
As I understand it, you added a new function for two reasons:
-
It needs the full page name, not basename.
-
titlepage(pagetitle($page)) reversability.
-
If you look at all the callers
Of pagetitle most of them pass a complete page name, not just the
basename. In most cases pagetitle is used to display the full name
of the page, including any subdirectory it's in. So why not just make
it consitently be given the full name of the page, with another argument
specifying if we want to get back just the base name.
-
I can't find any code that actually uses the reversability like that.
The value passed to titlepage always comes from some external
source. Unless I missed one.
- The use of
File::Spec->rel2abs is a bit scary.
- Does it really make sense to call
pagetitle on the meta title
in meta's nicepagetitle? What if the meta title is something like
"foo_bar" -- that would be changed to "foo bar".
- parentlinks is changed to use
nicepagetitle(bestlink($page, $path)).
Won't bestlink return "" if the parent page in question does not exist?
backlinks() is changed to add an additional title field
to the hash returned, but AFAICS this is not used in the template.- Shouldn't
Render.pm use nicepagetitle when getting the title for the
page template? Then meta would not need to override the title in the
pagetemplate hook. (Although this would eliminate handling of
title_overridden -- but that is little used and would not catch
all the other ways titles can be overridden with this patch anyway.)
I'm not a reviewer or anything, but can I chime in on changes to pagetitle?
I don't think having meta-titles in wikilinks and the parentlinks path by
default is necessarily a good thing. I don't consider the meta-title of a page
as used in <title> to be the same thing as the short title you
want in those contexts - IMO, the meta-title is the "formal" title of the page,
enough to identify it with no other context, and frequently too long to be used
as a link title or a parentlink, whereas the parentlinks title in particular
should be some abbreviated form that's enough to identify it in context.
tbm expressed a similar opinion when I was discussing
ikiwiki with him at the weekend.
Having a \[[!meta abbrev="..."]] that took precedence over title
in such contexts might be a good way to fix this? Or if your preference goes
the other way, perhaps a \[[!meta longtitle=""]] could take precedence
when generating the <title> and the title that comes after the parentlinks.
