-I like the idea of [[integrated issue tracking with ikiwiki]], and I do so on several wikis. However, as far as I can tell, ikiwiki has no functionality which can represent dependencies between bugs and allow pagespecs to select based on dependencies. For instance, I can't write a pagespec which selects all bugs with no dependencies on bugs not marked as done. --[[JoshTriplett]]

+
+Okie - I've had a quick attempt at this. Initial patch attached. This one doesn't quite work.
+And there is still a lot of debugging stuff in there.
+
+At the moment I've added a new preprocessor plugin, `definepagespec`, which is like
+shortcut for pagespecs. To reference a named pagespec, use `~` like this:
+
+ [ [!definepagespec name="bugs" spec="bugs/* and !*/Discussion"]]
+ [ [!definepagespec name="openbugs" spec="~bugs and !link(done)"]]
+ [ [!definepagespec name="readybugs" spec="~openbugs and !link(~openbugs)"]]
+
+At the moment the problem is in `match_link()` when we're trying to find a sub-page that
+matches the appropriate page spec. There is no good list of pages available to iterate over.
+
+ foreach my $nextpage (keys %IkiWiki::pagesources)
+
+does not give me a good list of pages. I found the same thing when I was working on
+this todo [[todo/Add_a_plugin_to_list_available_pre-processor_commands]].
+
+> I'm not sure why iterating over `%pagesources` wouldn't work here, it's the same method
+> used by anything that needs to match a pagespec against all pages..? --[[Joey]]
+
+>> My uchecked hypothesis is that %pagesources is created after the refresh hook.
+>> I've also been concerned about how globally defined pagespec shortcuts would interact with
+>> the page dependancy system. Your idea of internally defined shortcuts should fix that. -- [[Will]]
+
+>>> You're correct, the refresh hook is run very early, before pagesources
+>>> is populated. (It will be partially populated on a refresh, but will
+>>> not be updated to reflect new pages.) Agree that internally defined
+>>> seems the way to go. --[[Joey]]
+
+Immediately below is a patch which seems to basically work. Lots of debugging code is still there
+and it needs a cleanup, but I thought it worth posting at this point. (I was having problems
+with old style glob lists, so i just switched them off for the moment.)
+
+The following three inlines work for me with this patch:
+
+ Bugs:
+
+ [ [!inline pages="define(~bugs, bugs/* and ! */Discussion) and ~bugs" archive="yes"]]
+
+ OpenBugs:
+
+ [ [!inline pages="define(~bugs, bugs/* and ! */Discussion) and define(~openbugs,~bugs and !link(done)) and ~openbugs" archive="yes"]]
+
+ ReadyBugs:
+
+ [ [!inline pages="define(~bugs, bugs/* and ! */Discussion) and define(~openbugs,~bugs and !link(done)) and define(~readybugs,~openbugs and !link(~openbugs)) and ~readybugs" archive="yes"]]
+
+> Nice! Could the specfuncsref be passed in %params? I'd like to avoid
+> needing to change the prototype of every pagespec function, since several
+> plugins define them too. --[[Joey]]
+
+>> Maybe - it needs more thought. I also considered it when I was going though changing all those plugins :).
+>> My concern was that `%params` can contain other user-defined parameters,
+>> e.g. `link(target, otherparameter)`, and that means that the specFuncs could be clobbered by a user (or other
+>> weird security hole). I thought it better to separate it, but I didn't think about it too hard. I might move it to
+>> the first parameter rather than the second. Ikiwiki is my first real perl hacking and I'm still discovering
+>> good ways to write things in perl.
+>>
+>> What do you think is best to do about `is_globlist()`? At the moment it requires that the 'second word', as
+>> delimited by a space and ignoring parens, is 'and' or 'or'. This doesn't hold in the above example pagespecs (so I just hard wired it to 0 to test my patch).
+>> My thought was just to search for 'and' or 'or' as words anywhere in the pagespec. Thoughts?
+
+>> Oh, one more thing. In pagespec_translate (now pagespec_makeperl), there is a part of the regular expression for `# any other text`.
+>> This contained `()`, which has no effect. I replaced that with `\(\)`, but that is a change in the definition of pagespecs unrelated to the
+>> rest of this patch. In a related change, commands were not able to contain `)` in their parameters. I've extended that so the cannot
+>> contain `(` or `)`. -- [[Will]]
+
+>>> Updated patch. Moved the specFuncsRef to the front of the arg list. Still haven't thought through the security implications of
+>>> having it in `%params`. I've also removed all the debugging `print` statements. And I've updated the `is_globlist()` function.
+>>> I think this is ready for people other than me to have a play. It is not well enough tested to commit just yet.
