To select a set of pages, such as pages that are locked, pages
|
|
whose commit emails you want subscribe to, or pages to combine into a
|
|
blog, the wiki uses a PageSpec. This is an expression that matches
|
|
a set of pages.
|
|
|
|
The simplest PageSpec is a simple list of pages. For example, this matches
|
|
any of the three listed pages:
|
|
|
|
foo or bar or baz
|
|
|
|
More often you will want to match any pages that have a particular thing in
|
|
their name. You can do this using a glob pattern. "`*`" stands for any part
|
|
of a page name, and "`?`" for any single letter of a page name. So this
|
|
matches all pages about music, and any [[SubPage]]s of the SandBox, but does
|
|
not match the SandBox itself:
|
|
|
|
*music* or SandBox/*
|
|
|
|
You can also prefix an item with "`!`" to skip pages that match it. So to
|
|
match all pages except for Discussion pages and the SandBox:
|
|
|
|
* and !SandBox and !*/Discussion
|
|
|
|
Some more elaborate limits can be added to what matches using these functions:
|
|
|
|
* "`link(page)`" - match only pages that link to a given page (or glob)
|
|
* "`tagged(tag)`" - match pages that are tagged or link to the given tag (or glob)
|
|
* "`backlink(page)`" - match only pages that a given page links to
|
|
* "`creation_month(month)`" - match only pages created on the given month
|
|
* "`creation_day(mday)`" - or day of the month
|
|
* "`creation_year(year)`" - or year
|
|
* "`created_after(page)`" - match only pages created after the given page
|
|
was created
|
|
* "`created_before(page)`" - match only pages created before the given page
|
|
was created
|
|
* "`glob(someglob)`" - match pages that match the given glob. Just writing
|
|
the glob by itself is actually a shorthand for this function.
|
|
* "`internal(glob)`" - like `glob()`, but matches even internal-use
|
|
pages that globs do not usually match.
|
|
* "`title(glob)`", "`author(glob)`", "`authorurl(glob)`",
|
|
"`license(glob)`", "`copyright(glob)`" - match pages that have the given
|
|
metadata, matching the specified glob.
|
|
* "`user(username)`" - tests whether a modification is being made by a
|
|
user with the specified username. If openid is enabled, an openid can also
|
|
be put here.
|
|
* "`admin()`" - tests whether a modification is being made by one of the
|
|
wiki admins.
|
|
* "`ip(address)`" - tests whether a modification is being made from the
|
|
specified IP address.
|
|
* "`postcomment(glob)`" - matches only when comments are being
|
|
posted to a page matching the specified glob
|
|
|
|
For example, to match all pages in a blog that link to the page about music
|
|
and were written in 2005:
|
|
|
|
blog/* and link(music) and creation_year(2005)
|
|
|
|
Note the use of "and" in the above example, that means that only pages that
|
|
match each of the three expressions match the whole. Use "and" when you
|
|
want to combine expression like that; "or" when it's enough for a page to
|
|
match one expression. Note that it doesn't make sense to say "index and
|
|
SandBox", since no page can match both expressions.
|
|
|
|
More complex expressions can also be created, by using parentheses for
|
|
grouping. For example, to match pages in a blog that are tagged with either
|
|
of two tags, use:
|
|
|
|
blog/* and (tagged(foo) or tagged(bar))
|
|
|
|
Note that page names in PageSpecs are matched against the absolute
|
|
filenames of the pages in the wiki, so a pagespec "foo" used on page
|
|
"a/b" will not match a page named "a/foo" or "a/b/foo". To match
|
|
relative to the directory of the page containing the pagespec, you can
|
|
use "./". For example, "./foo" on page "a/b" matches page "a/foo".
