Render LaTeX equations in preview

[mroe]

When inputting the following into a note:
''$2^x$''
I would expect to see a LaTeX formula when previewing, however, this is not the case in my experience.
I have attached my configuration file.

I forgot to include my log and version numbers.
My log is attached; the version of RedNotebook is 1.1.8, and here's the relevant uname info:
Linux 2.6.40.4-5.fc15.x86_64 GNU/Linux

This is expected. You will only see the correct rendering in the rendered latex export (with pdflatex). I will keep this bug open as a wishlist bug.

I have looked into this and mathjax seems to be the best alternative here. However I wouldn't want to distribute mathjax with RedNotebook. Using the remote mathjax installation doesn't work reliably and will of course require an internet connection.

I just tried it and it seems inserting MathML will work, of course it's XML representation isn't exactly concise ;) However you will get a nice preview. Try inserting the following example from wikipedia:

'''
<math mode="display" xmlns="http://www.w3.org/1998/Math/MathML">
  <mrow>
    <mi>x</mi>
    <mo>=</mo>
    <mfrac>
      <mrow>
        <mo form="prefix">&#x2212;<!-- &minus; --></mo>
        <mi>b</mi>
        <mo>&#x00B1;<!-- &PlusMinus; --></mo>
        <msqrt>
          <msup>
            <mi>b</mi>
            <mn>2</mn>
          </msup>
          <mo>&#x2212;<!-- &minus; --></mo>
          <mn>4</mn>
          <mo>&#x2062;<!-- &InvisibleTimes; --></mo>
          <mi>a</mi>
          <mo>&#x2062;<!-- &InvisibleTimes; --></mo>
          <mi>c</mi>
        </msqrt>
      </mrow>
      <mrow>
        <mn>2</mn>
        <mo>&#x2062;<!-- &InvisibleTimes; --></mo>
        <mi>a</mi>
      </mrow>
    </mfrac>
  </mrow>
</math>

Eastern comes early this year ;) Formula support has now been added to the RedNotebook development code. Check it out: https://answers.launchpad.net/rednotebook/+faq/1925 Does it work for you?

Jendrik,
these are great news. Latex-formulae work fine here (Ubuntu 12.04, v.1.4.0 from ppa:rednotebook/stable)!
Thanks a lot.
