Content from sites such as YouTube can be embedded into a web page. Maybe
|
|
you want to do this. But you'll find that the [[plugins/htmlscrubber]]
|
|
doesn't let you. It blocks the tags used to embed such content, because
|
|
they can be abused in many evil ways.
|
|
|
|
Some plugins have been written to try to work around this problem, by
|
|
whitelisting the html needed to embed things from a few sites like Google
|
|
maps, calendar, videos, and YouTube. The problem with these plugins is that
|
|
they have to be kept up to date to add new sites, and follow changes to the
|
|
html such sites use for embedding.
|
|
|
|
(Digression: The real problem with the plugins is that they hide the
|
|
underlying trust relationship. If you decide to embed html from a site,
|
|
you'd better trust that site. And if ikiwiki lets you enter such html, it
|
|
needs to trust you.)
|
|
|
|
The [[plugins/htmlscrubber]] offers a different way around this problem.
|
|
You can configure it to skip scrubbing certain pages, so that content from
|
|
elsewhere can be embedded on those pages. Then use [[plugins/lockedit]]
|
|
to limit who can edit those unscrubbed pages.
|
|
|
|
For example, suppose your blog is all under `blog/*`, and you want
|
|
only yourself to be able to post there, and you'd like to be able to embed
|
|
youtube videos etc in your blog. Other users can edit some pages in the
|
|
wiki (Discussion pages, say), but not your blog posts. Then you could configure
|
|
ikiwiki as follows:
|
|
|
|
htmlscrubber_skip => 'blog/* and !*/Discussion',
|
|
locked_pages => '!*/Discussion',
|
|
|
|
More simply, you might want to allow yourself to embed content anywhere
|
|
on the wiki, but scrub content written on Discussion pages:
|
|
|
|
htmlscrubber_skip => '!*/Discussion',
|
|
locked_pages => '!*/Discussion',
|
