[pmwiki-users] deleted pages in pagelists

When a page is deleted it's, well, um, deleted. It's not meant to be viewed
within pmwiki anymore. It's kept around in that *,del-timestamp form so
that an *administrator* can go behind the scenes (either ftp or command
line) and rename it to undelete it. So I don't believe the capabilities you
are looking for exist - deleted files are meant to be inaccessible by
You may find a single place in the source (or a few) where it can be changed
to allow them to be viewed, but more likely you'll have to write a recipe
(or find one) that allows you to view and undelete deleted pages. (Note
that changing core source is frowned on because of the difficulty it
presents when you upgrade.) If you really need true browse/view/edit
privilege on deleted pages then you could theoretically write a different
pagestore class but you've got some relatively insurmountable obstacles in
doing that (if the same page was created and deleted and created and deleted
then you have 2 of the same page out there in the deleted form, each with a
different timestamp - which one would you choose?). It also seems somewhat
strange to give that kind of capability to "deleted" pages -- but you know
your functional specs.
Reading a page "from scratch" is not that difficult (see the read() function
within the pagestore class). You could set up some kind of markup or
?action=readdeleted or something like that which would read a given file on
disk and display the contents on a page. I can foresee your cookbook (that
already returns a list of filenames) returning them in a form something like
Page.X is pretty unimportant - whatever is there will probably just be
ignored as long as the action is readdeleted. Or, if you don't like setting
up a new ?action= then you could have some special markup on Page.X which
would look at the $_GET['pn'] and replace with the contents of the deleted
page. (Note that you have a bit of processing on the contents of the page
after you fread() or fgets() it, notably finding the line that starts with
text= and then doing a search/replace of %0a with carriage returns -- it's
actually a bit more complicated than that, but that's the basics - see
PageStore.read() for how it's meant to be done).
Looking at it from another perspective you could override the delete
capabilities (by extending the pagestore class with an override delete()
function) so that instead of deleting the page (which actually renames it to
group.page,del-timestamp) you would rename it and put it some group (like
"Deleted"). Thus when you "deleted" the page Hello.World it would be moved
to Deleted.Hello-World or something like that. Then you don't have to do
anything else except to exclude pages from the Deleted group in typical
pagelists and handle everything else in absolutely standard, vanilla pmwiki.
This is a much more elegant solution, but unfortunately it leaves any
already deleted files inaccessible - it only helps for pages that are
deleted after the change is made.
Long answer to a short question - I hope that helps get you started in the

this doesn't work.
Isn't there somewhere in the source code a pattern that excludes all files
named ".*?,del-.*" from the pagelists ?
