Consider the "All files in this package search" on
|
|
<http://packages.debian.org>. The URL for such a search looks like this:
|
|
|
|
http://packages.debian.org/cgi-bin/search_contents.pl?word=packagename&searchmode=filelist&case=insensitive&version=unstable&arch=i386
|
|
|
|
To create a "debfiles" [[shortcut|shortcuts]] that takes a package name, you
|
|
could just hardcode the architecture and distribution:
|
|
|
|
\[[!shortcut name=debfiles url="http://packages.debian.org/cgi-bin/search_contents.pl?word=%s&searchmode=filelist&case=insensitive&version=unstable&arch=i386"]]
|
|
\[[!debfiles ikiwiki]]
|
|
|
|
But what if you could have them as optional parameters instead? The syntax
|
|
for the invocation should look like this:
|
|
|
|
\[[!debfiles ikiwiki dist=testing]]
|
|
|
|
Some possible syntax choices for the shortcut definition:
|
|
|
|
\[[!shortcut name=debfiles url="http://packages.debian.org/cgi-bin/search_contents.pl?word=%s&searchmode=filelist&case=insensitive&version=%(dist)s&arch=%(arch)s" dist="unstable" arch="i386"]]
|
|
\[[!shortcut name=debfiles url="http://packages.debian.org/cgi-bin/search_contents.pl?word=%s&searchmode=filelist&case=insensitive&version=%(dist=unstable)s&arch=%(arch=i386)s"]]
|
|
\[[!shortcut name=debfiles url="http://packages.debian.org/cgi-bin/search_contents.pl?word=%s&searchmode=filelist&case=insensitive&version=%{dist=unstable}&arch=%{arch=i386}"]]
|
|
\[[!shortcut name=debfiles url="http://packages.debian.org/cgi-bin/search_contents.pl?word=$*&searchmode=filelist&case=insensitive&version=${dist=unstable}&arch=${arch=i386}"]]

Well, you can already do this kind of thing with templates. Invocation does
|
|
look different:
|
|
|
|
\[[!template id=debfiles package=ikiwiki dist=testing]]
|

|
|
> 3. I could use ikiwiki syntax in the template, not just HTML and
|
|
