سؤال

I'm trying to use pandoc to produce a html slideshow from a markdown file with some latex in it.

The file is here at github.

If I run the following pandoc command:

pandoc -s -t s5 --mathjax apresentacao.md -o index.html

The math is perfectly displayed by MathJax, but I only get a webpage with all the slides and no slideshow functionality.

If I run the follwing command:

pandoc -s --self-contained -t s5 --mathjax apresentacao.md -o index.html

I get a perfectly alright presentation, but MathJax fails to load. The resulting html file is (undestandably) full of binaries in it, for the images and javascript libraries that are loaded. But it seems to fail to incorporate MathJax correctly.

Do you guys had this issue? Are there any easy way to fix this?

I'm using the following pandoc version:

$ pandoc --version

المحلول

It's a known issue: --mathjax doesn't work well with --self-contained. I haven't studied it enough to come up with a fix yet, but suggestions welcome.

I just wrote a python script to compile markdown file into a standalone (requires internet connection) html file with mathjax support:

#!/usr/bin/env python
'''
pandoc_compile.py

Usage:
pandoc_compile.py markdown_file template_file
'''
import subprocess, re, sys, os

print("Compiling Markdown file: "+sys.argv[1])
print("Using template: "+sys.argv[2])
print("Output file: "+sys.argv[1]+".html")
pandoc_result = subprocess.Popen(['pandoc','--mathjax',sys.argv[1]], stdout=subprocess.PIPE).stdout.read()
with open(sys.argv[2]) as f: template = f.read()
final_result = re.sub('{{pandoc_output}}', pandoc_result, template)
with open(sys.argv[1]+".html", "w") as f: f.write(final_result)

It compiles markdown with pandoc and then places the result in the following html template.

<html>

<head>
<script type="text/javascript"
  src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>
</head>

<body>

{{pandoc_output}}

</body>
