1 As documented in [[plugins/write]], the current `renamepage` hook is
2 heavily oriented towards updating links in pages' content: it is run
3 once per page linking to the renamed page.
5 That's fine, but it can't be used to trigger more general actions on
6 page rename. E.g. it won't be run at all if the page being renamed is
9 This is a real issue for the [[plugins/contrib/po]] development: what
10 I'm about to achieve is:
12 - when a master page is renamed, the plugin takes notice of it (using
13 the `rename` hook), and later renames the translation pages
14 accordingly (in the `change` hook)
15 - when a master page is deleted, the plugin deletes its translations
16 (using the `delete` hook)
18 With the current `renamepage` hook behavior, combining these two goals
19 has an annoying drawback: a plugin can't notice an orphan master page
20 has been renamed, so instead of renaming (and preserving) its
21 translations, it considers the oldpage as deleted, and deletes its
22 translations. Game over.
24 It may seem like a corner case, but I want to be very careful when
25 deleting files automatically in `srcdir`, which is not always under
28 As a sad workaround, I can still disable any deletion in `srcdir`
29 when it is not under version control. But I think ikiwiki deserves
30 a global `renamepage` hook that would be run once per rename
35 - keep the documented `renamepage` hook as it is
36 - use something inspired by the trick `preprocess` uses: when `hook`
37 is passed an optional "global" parameter, set to a true value, the
38 declared `renamepage` hook is run once per rename operation, and is
39 passed named parameters: `src`, `srcfile`, `dest` and `destfile`.
41 I'm of course volunteering to implement this, or anything related that
42 would solve my problem. Hmmm? --[[intrigeri]]
