This looks very interesting, do you have an example implementation with formulae we could see?

RafalR

Instance of Vanilla I created this extension for is private, but effect you can see on the screenshot.
Syntax and rendered images are the same as in Wikipedia.

Example formula could be: [math]\int{\sin{x^\frac{3}{2}}dx}[/math]
And effect:

aerocapture

After installing and enabling this extension, posts with the [math][/math] construct result in the following PHP error message:

Fatal error: Call to undefined function: htmlspecialchars_decode()
in /.../community/extensions/VanillaTeX/default.php on line 26

The path to all texvc files is /extensions/VanillaTeX/texvc/texvc. Any ideas?

Vincent

replace htmlspecialchars_decode() with html_entity_decode()?

aerocapture

Ah, thanks Vincent. Yeah htmlspecialchars_decode() is only supported by PHP5.1+ and my server's running 4.3. Your fix kills the PHP error message, but the [math] constructs still don't convert to LaTeX images (i.e., "Formula rendering error."). I'll see if I can figure out what's going on.

Am I possibly missing things on my server, e.g. dvipng and/or latex? What other dependencies does texvc have?

RafalR

Yes, it has dependencies on dvips, latex and convert (from ImageMagick) (It's in the texvc's README).
According to README from texvc if you want to have non-ASCII unicode chars you need also cjk-latex package in Debian.

Would this basically allow you to embed LaTeX docs in a post? I haven't installed it and tested, but it seems like a neat feature if that is the case.

Hi, I have the same problems as aerocapture and would ask you to give a more detailed installation instruction please. I would really aprreciate it.

Moreover the link to texvc.zip to your(?) site is dead and I´m not sure which files I have to copy from the MediaWiki link.

I would also like to see this extension in use but have the same problems as aerocapture and gebbissimo

Whats happening with this extension? did it die?

Cochise

Like to know is anyone has got this extension working recently. This is a real plus for Vanilla if it was working, and a main reason I would like to use Vanilla on my site.

The link to the texvc.zip is not working anymore, alternatively I found: http://www.s64.xrea.com/texvc.zip

But anyway, I'm still getting "Formula rendering error. Correct the formula and try again." (the formula syntax is correct)
