Conversion to slide not taking extensions into account

[hugues-talbot]

Hello,

I cannot make use of both reveal.js slides and latex notebook extensions. In the slides, I simply get the unconverted code (see screenshot).

In other words, a command like

jupyter nbconvert --to slides_with_lenvs

is mssing.

This is a good idea for improvement and should be easy.
For now, you can try to

• locate the templates associated with the latex_envs package; in my system they are located in /usr/local/lib/python3.5/site-packages/latex_envs/templates; but this depends on the system you use and the way you installed the package (as a system or user package)
• edit the template latex_envs.tpl and replace {%- extends 'full.tpl' -%}(first line) by {%- extends 'slides_reveal.tpl' -%}

AhAh. No. Not that easy. :-(
There is a dedicated exporter for slides, which adds data to the notebook itself before conversion; so one has to keep all that in a special preprocessor. I write this in my todo...

If you are really in a hurry, you can (probably) convert to slides, and then add latex_envs support by hands.
Add this at the beginning

<!-- javascript from CDN for conversion -->
  <script src="https://cdnjs.cloudflare.com/ajax/libs/marked/0.3.5/marked.js"></script>

<script type="text/x-mathjax-config">
// make sure that equations numbers are enabled
MathJax.Hub.Config({ TeX: { equationNumbers: {
    autoNumber: "AMS", // All AMS equations are numbered
    useLabelIds: true, // labels as ids
    // format the equation number - uses an offset eqNumInitial (default 0)
    formatNumber: function (n) {return String(Number(n)+Number(1)-1)} 
    } } 
});
</script>

and this at the end of the head (before </head>)

Export to slides using

jupyter nbconvert --to slides_with_lenvs FILE.ipynb

is available in version 1.4.3 at Pypi of in this repo. Enjoy.

Hello JFB As stated, this works well. This yields a single HTML page with the correct equations, numberings, etc. Very useful ! However it does not work with reveal.js jupyter nbconvert --to slides_with_lenvs Perceptron.ipynb --post serve Yields (see screenshot). [Math Processing Error] \newcommand{\M}[1]{\mathbf{#1}} Any idea ? Thanks again.

There is no screenshot.

Anyway this is probably unrelated to latex_envs. It means that your mathjax processor fails somewhere; because of your browser, your internet connexion or of cache issues. Try to clear the cache (press shift while reloading; or use your browser preferences).

OK it might indeed be a browser issue indeed because with the fixed HTML version (without the reveal.js script) I sometime get the error, sometime not.

It works well in Firefox & Chrome after restarting the browsers. Thanks !
