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
+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
* and !SandBox and !*/Discussion
-It's also possible to match pages that link to a given page, by writing
-"`link(page)`". Or, match pages that a given page links to, by
-writing "`backlink(page)`". Or match pages created in a given month, year,
-or day of the month by writing "`creation_month(month)`",
-"`creation_year(year)`" or "`creation_day(mday)`".
+Some more elaborate limits can be added to what matches using any of these
+functions:
-For example, to match all pages in a blog that link to the page about music
-and were written on Mondays in 2005:
+* "`link(page)`" - match only pages that link to a given page
+* "`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
- blog/* and link(music) and creation_year(2005) and creation_day(0)
+For example, to match all pages in a blog that link to the page about music
+and were written in 2005:
-Matches can also be used to limit matching to pages created before or after
-a given date.
+ blog/* and link(music) and creation_year(2005)
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
blog/* and (link(tag/foo) or link(tag/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".
