Hi Joey,
What do you think about CSS classes for links to display link with icon?
You probably know that there are wikis with that feature, for example
Moin Moin.
Here is a piece of `common.css` file grabbed from <http://wiki.openwrt.org>
site which is powered by Moin Moin wiki:
a.www:before {content: url(../img/moin-www.png); margin: 0 0.2em;}
a.http:before {content: url(../img/moin-www.png); margin: 0 0.2em;}
a.https:before {content: url(../img/moin-www.png); margin: 0 0.2em;}
a.file:before {content: url(../img/moin-ftp.png); margin: 0 0.2em;}
a.ftp:before {content: url(../img/moin-ftp.png); margin: 0 0.2em;}
a.nntp:before {content: url(../img/moin-news.png); margin: 0 0.2em;}
a.news:before {content: url(../img/moin-news.png); margin: 0 0.2em;}
a.telnet:before {content: url(../img/moin-telnet.png); margin: 0 0.2em;}
a.irc:before {content: url(../img/moin-telnet.png); margin: 0 0.2em;}
a.mailto:before {content: url(../img/moin-email.png); margin: 0 0.2em;}
a.attachment:before {content: url(../img/moin-attach.png); margin: 0 0.2em;}
a.badinterwiki:before {content: url(../img/moin-inter.png); margin: 0 0.2em;}
a.interwiki:before {content: url(../img/moin-inter.png); margin: 0 0.2em;}
You can see that they use a lot of CSS classes for links, but only one CSS class
for external links is enough for me :) Please look at my example:
\[[Foo]] -> <a href="http://www.mywiki.org/foo.html">Foo</a>
\[[Bar|foo/bar]] -> <a href="http://www.mywiki.org/foo/bar.html">Bar</a>
<http://www.gnu.org/> -> <a class="external" href="http://www.gnu.org/">http://www.gnu.org/</a>
[GNU](http://www.gnu.org/) -> <a class="external" href="http://www.gnu.org/">GNU</a>
[RMS](mailto:rms@gnu.org) -> <a href="mailto:rms@gnu.org">RMS</a>
My best regards,
