Easy WP LaTeX

Easy WP LaTeX provides a very easy way to display equations or mathematical formulas (typed in as TeX or LaTeX code) in your posts. It lets you customize colors and sizes of your equations to match your blog theme.

Live Demo

If you would like to see the plugin action, visit this physics post. You can even play with its admin interface at the live demo site.

Most LaTeX/equation plugins I have seen suffer from a few drawbacks.

  1. They require installations of TeX or other packages on your server.
  2. They are fairly inflexible in terms of colors of text and background.
  3. Each time you switch your theme, you have to re-configure your color scheme.
  4. They may not let you choose how to input LaTeX code. ([math]...[/math] or $$...$$) without editing the plugin code.

My plugin aims to be flexible, and easy to install (no geeky code editing etc.). It is now available in your own language using machine translation curtsey of Google and Microsoft.

Pro Version

This release is the freely distributed version of Easy WP LaTeX. It is fully functional. But the Pro Version gives you more features and benefits.

  1. In the Pro version, the plugin caches the formula images so that your pages load faster.
  2. You also get an option to align the formula image with respect to the text around it by tweaking the vertical alignment of your equations.

New features and bug fixes will first appear in the Pro version before being ported to this freely distributed edition.

Alternatives

  1. Latex for WordPess by zhiqiang, on which this plugin is based, has caching and JS based image generation. But it lacks intuitive color matching and theme-dependent settings.
  2. JetPack also lets you insert LaTeX formulas, again color matching is not easy.

Installation

Searching

The easiest way to install this plugin is to use the WordPress Admin interface. Go to your admin dashboard, find the "Plugins" menu, and click on "Add New". Search for this plugin and click on "Install Now" and follow the WordPress instructions.

Uploading

If you want to download it and manually install, you can again use the WordPress dashboard interface. First download the plugin zip file to your local computer. Then go to your admin dashboard, find the "Plugins" menu, and click on "Add New". After clicking on the "Add New" menu item as above, click on "Upload" (below the title "Install Plugins" near the top). Browse for your downloaded zip file, upload it and activate the plugin.

To install the professional version of the plugin, please deactivage the Lite version (if any) first. Then upload the zip file that you download after your purchase using the WordPress admin interface shown below.

[install]

The plugin is updated also by following the same process, preferably from the plugin Admin page where you will see a file-upload form when an update is ready. The first update for your purchased plugin is always free.

Frequently Asked Questions

How come there is not a single frequently asked question?

Two possible reasons.

  1. Easy WP LaTeX is so simple and straight-forward that no question could be thought of.
  2. More likely, the plugin is too new for any questions.
