-OTHERLANGUAGES dependencies
----------------------------
+1. updates the POT file and the PO files for the "slave" languages;
+   the updated PO files are then put under version control;
+2. triggers a refresh of the corresponding HTML slave pages.

 
 

-Pages using `OTHERLANGUAGES` must depend on any "master" and "slave"
-pages whose status is being displayed. It will trigger dependency
-loops; how to sort this out?
+Also, when the plugin has just been enabled, or when a page has just
+been declared as being translatable, the needed POT and PO files are
+created, and the PO files are checked into version control.

 
 

-Should pages using the `OTHERLANGUAGES` template loop be declared as
-linking to the same page in other versions? To be rigorous, they
-should, but this may clutter the backlinks.
+Discussion pages
+----------------

 
 

-Automatic PO files update
--------------------------
+Discussion should happen in the language in which the pages are
+written for real, *i.e.* the "master" one. If discussion pages are
+enabled, "slave" pages therefore link to the "master" page's
+discussion page.

-   files must then be put under version control
+One can edit the PO files using ikiwiki's CGI (a message-by-message

-2. triggers a refresh of the corresponding HTML slave pages: this is

+Security checks
+---------------
+
+- Can any sort of directives be put in po files that will
+  cause mischief (ie, include other files, run commands, crash gettext,
+  whatever).
+- Any security issues on running po4a on untrusted content?
+
+gettext/po4a rough corners
+--------------------------
+
+- fix infinite loop when synchronizing two ikiwiki (when checkouts
+  live in different directories): say bla.fr.po has been updated in
+  repo2; pulling repo2 from repo1 seems to trigger a PO update, that
+  changes bla.fr.po in repo1; then pushing repo1 to repo2 triggers
+  a PO update, that changes bla.fr.po in repo2; etc.; fixed in
+  `629968fc89bced6727981c0a1138072631751fee`?
+- new translations created in the web interface must get proper
+  charset/encoding gettext metadata, else the next automatic PO update
+  removes any non-ascii chars; possible solution: put such metadata
+  into the Pot file, and let it propagate; should be fixed in
+  `773de05a7a1ee68d2bed173367cf5e716884945a`, time will tell.

+Misc. improvements
+------------------

 
 

-Also, when the plugin has just been enabled, or when a page
-has just been declared as being translatable:
+### page titles

 
 

-- all the needed POT and PO files are be created
-- **FIXME** the PO files must be checked into version control
+Use nice page titles from meta plugin in links, as inline already
+does. This is actually a duplicate for
+[[bugs/pagetitle_function_does_not_respect_meta_titles]], which might
+be fixed by something like [[todo/using_meta_titles_for_parentlinks]].

 
 

-Security checks:
+### backlinks

 
 

-- `refreshpofiles` uses `system()`, whose args have to be checked more
-  thoroughly to prevent any security issue (command injection, etc.).
-- `refreshpofiles` and `refreshpot` create new files; this may need
-  some checks, e.g. using `IkiWiki::prep_writefile()`
+`po_link_to = negotiated`: if a given translatable `sourcepage.mdwn`
+links to \[[destpage]], `sourcepage.LL.po` also link to \[[destpage]],
+and the latter has the master page *and* all its translations listed
+in the backlinks.
+
+`po_link_to = current`: seems to work nicely
+
+### parentlinks
+
+When `usedirs` is disabled and the home page is translatable, the
+parent link to the wiki home page is broken (`/index.html`).

-Translating online
-------------------
-
-As PO is a wiki page type, we already have an online PO editor, that

-A message-by-message interface could also be implemented at some

-
-Translating offline without VCS access
---------------------------------------
-
-The following workflow should be made possible for translators without
-VCS access who need to edit the PO files in another editor than a web
-browser:
-
-- download the page's PO file
-- use any PO editor to update the translation
-- upload the updated PO file
-
-Implementation note: a generic mechanism to upload a page's source is
-needed: it's only an alternative way to allow saving a the modified
-page's source with the CGI.
-
-### Short-term workflow
-
-A possible workaround is:
-
-- pretend to edit the PO file online
-- copy the PO file content from the textarea
-- cancel the edit
-- paste the content into a local file.
-- edit the local file in any PO editor
-- pretend to edit the PO file online
-- paste the modified local file's content into the edit textarea
-- save
