Hello org-users,
I know that it is possible to export equations as images if you set the variable
org-export-with-LaTeX-fragments to t, but I prefer to use jsMath
(http://www.math.union.edu/~dpvc/jsMath/) for equation in HTML. The problem is
that when org-export-with-LaTeX-fragments is set to nil org-mode interprets
underlines, hats and Greek letters and replace them in the generated HTML.
I agree that this is nice in most cases, but I need them to be left untouched,
since they will be later interpreted by jsMath when I'm viewing the page in a
browser that supports java-script. Therefore, my "feature request" is disabling
this smart behavior of org-mode when latex fragments are not converted to
images.
I also need to add a line in the HTML header to load the jsMath script, but this is
easily accomplished with the line
#+STYLE: <SCRIPT SRC="../jsMath/easy/load.js"></SCRIPT>
in the org-file header.
Here are some advantages and disadvantages about using jsMath instead of images.
Advantages:
- It's really pretty when you have all the fonts installed and you can zoom
without any loss of quality.
- No need to generate images when exporting
+ When you see the generated HTML page the jsMath script is run each time you
reload the page. Because modern browsers are increasing more and more the
efficiency of the java-script engine this is not a problem even if there are
a lot of equations in the generated page.
+ On the other hand, creating images when exporting can take considerable
time when there are man equations.
Disadvantages
- More difficult to setup
+ you have to install jsMath for authors, since you are creating pages with it.
+ you have to install jsMath for users, that is, install the fonts that will
be used. If this is not done, jsMath will use images for the equations. You
won't need to generate images when exporting, since jsMath already has all
images (it just put the pieces together)
- It is more inconvenient to send the generated HTML page to a friend, since
your friend will need to install the fonts used by jsMath.

Since they are ignored by jsMath I get the correct equations and the only minor annoyance is that the font of the Greek letters is not as nice as if it were replace by jsMath (jsMath fonts are equivalent to latex fonts). If it is something easy to do, an option to also turn-off the replacements of Greek letters by org-mode would be nice, but don't bother if it is to much work. I'll write the instructions of how to use jsMath with org-mode here soon.

You can just use LaTeX conventions and write $\alpha$ instead of the lazy \alpha.

Because the efficiency of the java-script engine in modern browsers are increasing more and more these replacements are usually fast even if there are a lot of equations in the generated page. + On the other hand, creating images when exporting can take considerable time when there are many equations. - Disadvantages :: - It is more difficult to setup + you have to install jsMath for authors, since you are creating pages with it. + you have to install jsMath for users, that is, install the fonts that will be used.

You won't need to generate the images when exporting, since jsMath already has all images (it just put the pieces together) - It is more inconvenient to send the generated HTML page to a friend, since your friend will need to install the fonts used by jsMath. Because we are going to process the latex code with jsMath, the variable org-export-with-LaTeX-fragments must be set to nil and the options : #+OPTIONS: ^:nil : #+OPTIONS: LaTeX:nil must be in the beginning of the org file. These measures are necessary assure that the latex code will be left intact by org-mode. * Download jsMath First we need to download jsMath for authors as explained in http://www.math.union.edu/~dpvc/jsMath/download/jsMath.html. The necessary files are [[http://sourceforge.net/project/showfiles.php?group_id=172663][here]]. Download the latest version of jsMath and also the "jsMath Image Fonts"[fn:1] file. Don't bother with the sprite fonts. * Installation and configuration of jsMath Unpack the jsMath and jsMath-image-fonts archives, and place the fonts folder from the second archive into the jsMath folder from the first archive. That is, the fonts folder should be in the same folder as the jsMath.js file. The main configuration file for jsMath is the easy/load.js script. We need to tell org-mode to include this script in each generated HTML file. Assuming that the jsMath folder is in the same parent folder as the folder containing the .org files, we can just add : #+STYLE: <SCRIPT SRC="../jsMath/easy/load.js"></SCRIPT> to the beginning of each org file. Alternatively, if org-publish is utilized we can put : :style "<link rel=\"stylesheet\" type=\"text/css\" href=\"../stylesheet.css\" />" in the project definition. With that, when the HTML generated by org-mode is viewed in the browser jsMath will replace the equations inside the math delimiters appropriately[fn:2]. By default, jsMath recognizes =\(= and =\)= as math delimiters for inline equations, and =\[= and =\]= (in addition to =$$=) as math delimiters for display equations. To recognize =$= as math delimiters for inline equations change "processSingleDollars:" to 1 in the easy/load.js file. You will probably want to load some additional plugins (for instance, AMSSymbols). In order to do that search for : loadFiles: [], in the easy/load.js file and add each plugin name separated by comma. Here I use : loadFiles: ["extensions/AMSmath.js","extensions/AMSsymbols.js", "extensions/autobold.js", "extensions/eqn-number.js"], The plugins AMSmath and AMSSymbols are self-explanatory and you will need them if you are using symbols or environments provided by AMS such as the symbol =\triangleq=. The plugin eqn-number is really nice. It will number equations that have a label and allow you to reference them later with the ref command. For instance : \[ : \label{a_label} : x=2*y : \] : Bla bla bla from equation \(\ref{a_label}\) will create a numbered equation that can be referred as showed in the example[fn:3]. The reference is a link to the equation. The plugin autobold causes jsMath to use \boldsymbol{...} around mathematics that appears within <B>...</B> tags or has font-weight:bold applied via CSS rule. Look in the extensions folder for other plugins (some of them are loaded automatically by jsMath and it is not necessary to include them in the loadFiles). As last, if the browser freezes when jsMath is being loaded, try disable the autoload feature in the easy/load.js file. * As pretty as it can get jsMath should be working with org-mode by now, but it is using the image fonts and warns the user with a red frame at the top of the page. That means that the "installation for authors" part is done and now we only need to install some .ttf fonts available at the jsMath website. Download the file [[http://www.math.union.edu/~dpvc/jsMath/download/TeX-fonts-linux.tgz][TeX-fonts-linux.tgz]] in the website. and extract the files to ~/.fonts. The package TeX-fonts-linux has the most common ones, but it is also good to install the extra fonts (to see, for instance, the "mathcal" symbols). * Extra fonts Some additional fonts available in the [[http://www.math.union.edu/~dpvc/jsMath/download/extra-fonts/welcome.html][extra fonts]] page are useful. Download the zip file for authors (for instance bbold10.zip) and extract it to the jsMath/fonts folder. Then download the corresponding .ttf file to the ~/.fonts (I prefer the light version because the dark version may be confused with bold). You don't need to install all of the extra fonts. The ones I found useful are bbold10, cmbsy10, cmmib10, msam10 and msbm10[fn:4]. * Footnotes [fn:1] The Image Fonts are the images of each symbol that jsMath uses as a fallback when the user does not have the ttf fonts installed. We will install these fonts later and it would be possible to avoid installing the image fonts, but it requires an additional configuration step. [fn:2] A button "jsMath" should appear at the bottom east of the page. [fn:3] The Math delimiters are necessary to tell jsMath to process the \ref command. [fn:4] Without the extra fonts some symbols won't be showed even if the plugin is loaded, such as the \triangleq symbol.
