As documented in [[plugins/write]], the current renamepage hook is
heavily oriented towards updating links in pages' content: it is run
once per page linking to the renamed page.
That's fine, but it can't be used to trigger more general actions on
page rename. E.g. it won't be run at all if the page being renamed is
an orphan one.
This is a real issue for the [[plugins/contrib/po]] development: what
I'm about to achieve is:
- when a master page is renamed, the plugin takes notice of it (using
the
rename hook), and later renames the translation pages
accordingly (in the change hook)
- when a master page is deleted, the plugin deletes its translations
(using the
delete hook)
With the current renamepage hook behavior, combining these two goals
has an annoying drawback: a plugin can't notice an orphan master page
has been renamed, so instead of renaming (and preserving) its
translations, it considers the oldpage as deleted, and deletes its
translations. Game over.
It may seem like a corner case, but I want to be very careful when
deleting files automatically in srcdir, which is not always under
version control.
As a sad workaround, I can still disable any deletion in srcdir
when it is not under version control. But I think ikiwiki deserves
a global renamepage hook that would be run once per rename
operation.
My proposal is thus:
- keep the documented
renamepage hook as it is
- use something inspired by the trick
preprocess uses: when hook
is passed an optional "global" parameter, set to a true value, the
declared renamepage hook is run once per rename operation, and is
passed named parameters: src, srcfile, dest and destfile.
I'm of course volunteering to implement this, or anything related that
would solve my problem. Hmmm? --[[intrigeri]]
I think it would be better to have a different hook that is called for
renames, since the two hook actions are very different (unlike the
preprocess hook, which does a very similar thing in scan mode).
Just calling it rename seems like a reasonable name, by analogy with
the delete and change hooks.
It might make sense to rename renamepage to renamelink to make it
clearer what it does. (I'm not very worried about this breaking things, at
this point.) --[[Joey]]
In my po branch, I renamed renamepage to renamelink, and
created a rename hook that is passed a reference to @torename.
--[[intrigeri]]
As Joey highlights it on [[plugins/contrib/po]], it's too late to
merge such a change, as the 3.x plugin API is released and should
not be broken. I'm thus proposing to keep the existing
renamepage as it is, and call rename the global hook I need.
