We should support SVG. In particular:
|
|
|
|
|
|
|
|
|
|
* We could support rendering SVGs to PNGs when compiling the wiki. Not all browsers support SVG yet.
|
|
|
|
|
|
|
|
|
|
* We could support editing SVGs via the web interface. SVG can contain unsafe content such as scripting, so we would need to whitelist safe markup.

I'm allowing for inline SVG on my own installation. I've patched my
|
|
|
|
|
copy of htmlscrubber.pm to allow safe MathML and SVG elements (as
|
2008-03-21 04:06:41 +01:00
|
|
|
implemented in html5lib). <del datetime="2008-03-20T23:04-05:00">Here's a patch
|

|
|

if anyone else is interested.</del>
|

<ins datetime="2008-03-20T23:05-05:00">Actually, that patch wasn't quite
|
|
|
|
|
right. I'll post a new one when it's working properly.</ins> --[[JasonBlevins]]

I'd like to hear what people think about the following:
|
|
|
|
|
|
|
|
|
|
1. Including whitelists of elements and attributes for SVG and MathML in
|
2008-03-21 16:40:33 +01:00
|
|
|
htmlscrubber. See my current [htmlscrubber.pm][] and the [diff][]
|
2008-03-21 16:19:00 +01:00
|
|
|
from the current trunk.
|
|
|
|
|
|
|
|
|
|
2. Creating a whitelist of safe SVG (and maybe even HTML) style
|
|
|
|
|
attributes such as `fill`, `stroke-width`, etc.
|
|
|
|
|
|
|
|
|
|
This is how the [sanitizer][] in html5lib works. It shouldn't be too
|
|
|
|
|
hard to translate the relevant parts to Perl.

Another problem is that [HTML::Scrubber][] converts all tags to lowercase.
|
|
|
|
|
Some SVG elements, such as viewBox, are mixed case. It seems that
|
|
|
|
|
properly handling SVG might require moving to a different sanitizer.
|
|
|
|
|
It seems that [HTML::Sanitizer][] has functions for sanitizing XHTML.
|
|
|
|
|
Any thoughts? --[[JasonBlevins]], March 21, 2008 13:54 EDT
