For example, to limit arbitrary files to 50 kilobytes, but allow
larger mp3 files to be uploaded by joey into a specific directory, and
-check all attachments for virii, something like this could be used:
+check all attachments for viruses, something like this could be used:
virusfree() and ((user(joey) and podcast/*.mp3 and mimetype(audio/mpeg) and maxsize(15mb)) or (!ispage() and maxsize(50kb)))
-The regular [[ikiwiki/PageSpec]] syntax is expanded with thw following
+The regular [[ikiwiki/PageSpec]] syntax is expanded with the following
additional tests:
-* maxsize(size)
-
- Tests whether the attachment is no larger than the specified size.
- The size defaults to being in bytes, but "kb", "mb", "gb" etc can be
- used to specify the units.
+* "`maxsize(size)`" - tests whether the attachment is no larger than the
+ specified size. The size defaults to being in bytes, but "kb", "mb", "gb"
+ etc can be used to specify the units.
-* minsize(size)
-
- Tests whether the attachment is no smaller than the specified size.
-
-* ispage()
+* "`minsize(size)`" - tests whether the attachment is no smaller than the
+ specified size.
- Tests whether the attachment will be treated by ikiwiki as a wiki page.
- (Ie, if it has an extension of ".mdwn", or of any other enabled page
- format).
+* "`ispage()`" - tests whether the attachment will be treated by ikiwiki as a
+ wiki page. (Ie, if it has an extension of ".mdwn", or of any other enabled
+ page format).
So, if you don't want to allow wiki pages to be uploaded as attachments,
use `!ispage()` ; if you only want to allow wiki pages to be uploaded
as attachments, use `ispage()`.
-* user(username)
-
- Tests whether the attachment is being uploaded by a user with the
- specified username. If openid is enabled, an openid can also be put here.
-
-* ip(address)
-
- Tests whether the attacment is being uploaded from the specified IP
- address.
-
-* mimetype(foo/bar)
-
- This checks the MIME type of the attachment. You can include a glob
- in the type, for example `mimetype(image/*)`.
-
-* virusfree()
+* "`mimetype(foo/bar)`" - checks the MIME type of the attachment. You can
+ include a glob in the type, for example `mimetype(image/*)`.
- Checks the attachment with an antiviral program.
+* "`virusfree()`" - checks the attachment with an antiviral program.
