LaTeX to WordPress

Phillip Lord

This post describes the process of posting to WordPress from a LaTeX source file, using tools generated as part of the Knowledgeblog project.

1 Introduction

About a month ago, we managed to get funding from JISC for knowledgeblog; the idea is to turn a blog platform from something for light commentary into a framework for serious scientific publication. One of the key requirements for this is to fit in with peoples existing working practices; and for this, we need a good document creation environment. This means word and latex. I’ve been working mostly on the latter, and this post is the first outcome. It’s generated totally automatically from latex. This is an advance on my paper on realism which was semi-automatically converted, with some hand editing of the HTML.

At the moment, the tool-chain is a little bit clunky, but it will improve! This is not meant to be an annoucement that all is ready, just an early alpha release and proof-of-principle.

2 Implementation

The implementation of these tool-chain uses three pieces of software:


This package, that I have written, uses plasTeX to parse and render the latex into HTML. Most of the work is being performed by plasTeX out-of-the-box, although using a non-default configuration. Math-mode is being treated separately however, rather than using plasTeXs default image rendering approach.


blogpost is being used to actually post the generated HTML onto the web. The HTML can also be cut-and-paste directly into wordpress, but blogpost is easier for me, as its the usual tool I use anyway (normally over asciidoc source). Blogpost is unmodified.


This is a wordpress plugin, that I have written, which uses MathJax to render math-mode from the original latex in the browser. The plugin just injects the mathjax javascript headers into a post on-demand (i.e. only on posts with math-mode in them).

Currently, this is all held together with some dodgy makefiles; this will be improved in time.

The first and last of these tools are available from knowledgeblog. I’ve tested them on Ubuntu 10.04 and they are in alpha. Comments are welcome, to knowledgeblog-discuss.

3 Key Features

At the moment, I haven’t fully explored all the features of LaTeX that are well supported. However, all the structural elements (sections, lists), bibliographies, links via the hyperref package all seem to work well.

The math mode rendering works well. I’ve been using one famous equation: \(E=mc^2\), as my main test. But more complex examples work also. This is from mathjax:\(J_\alpha (x) = \sum _{m=0}^\infty \frac{(-1)^ m}{m! \, \Gamma (m + \alpha + 1)}{\left({\frac{x}{2}}\right)}^{2 m + \alpha }\).

I’ve made a few tweaks to this also for common idioms. So the lesser than symbol is written in mathmode in latex but rendered directly in HTML: <.

4 Future Work

There are many things left to do yet. The process needs to made smooother, with a single tool to hook the current tool-chain together; it would be good to attach a PDF generated from the latex also. Currently, titles are set independently (which is why this post appears to have two titles). The mathjax plugin needs configuration options (it overwrites wp-latex functionality at the moment). And there is significant testing to do to see what advanced features (figures critically!) work and don’t work. Still, it’s good to see that most of the tools that I needed to get this work already existed. With luck, most of the other tools we need will be as good.
