agrbin / svgtex Goto Github PK

The SVG result contains 'use' elements that have duplicate xlink:href elements. That is, using two terminal windows (this is win7)

1. phantomjs.exe main.js
2. wget http://localhost:16000/?q=x+e -O test.svg

The resulting SVG has 'use' elements like this:

<use xlink:href="#MJMATHI-78" x="0" y="0" xlink:href="#MJMATHI-78">

What I did to fix it was to replace line 73 in engine.js, which inserts the attribute, with this conditional block:

  if (uses[k]["href"] === undefined) {
      uses[k].setAttribute("xlink:href", id);
  }

A long math formula, which however would fit well in a single line when rendered, is not rendered and is left as text. This is the example that fails for me:

$\displaystyle \delta \sigma^\prime_e = |\frac{d \sigma^\prime_e}{d \alpha} \cdot \frac{\delta\alpha}{\alpha} \cdot \alpha| = \frac{2}{3} \alpha \frac{\delta\alpha}{\alpha} \alpha = \frac{2}{3} \frac{1}{137.035999084^2} \cdot 1.5\times 10^{-10} = 5.3\times 10^{-15}$

Thanks for this nice piece of software!

This "fix" has caused a major regression and rendered svgtex completely useless on GNU/Linux (Xubuntu LTS 14.04). On all my browsers (Firefox, Chrome, etc.), I now only see one or more horizontal lines instead of any formula. Reverting that commit fixes the problem.

Could you explicitly declare the license (BSD, MIT, Apache, etc...) of this project?

Hello,
Your work is awesome. It works pretty well. However, I suggest, a stand alone version without relying on the http communication would be better. There is no guaranteed that you could set up server port on every machine with your main.js. I also tried to develop a MathJax stand alone component for QT platform. I encountered the problem that in page simple JavaScript were executed. However the screen shot doesn't have rendered math. If you would like to tell me how you solved the rendering issue with MathJax, that would be very helpful. We together make a better one, if you don't mind.

I wrote a proposal to extend Pandoc's (X)HTML writer with support for SvgTex. This would allow to inject SVG math directly into the (X)HTML rendered by Pandoc.

Please, express your support in favour of this proposal over at the pandoc forum!

Hello,

There is no guaranteed that you could set up server port on every machine with your main.js. Plus, your html code rely on the mathjax on cdn.com. It is better to use local MathJax.js.
