MathJax v3 Developers Tools

Some developers tools for testing local MathJax v3 code base.

General setup

To run most scripts in the tools you need to connect to your current version of MathJax3. Assuming that MathJax3 sources are at <MJ3-PATH> you need to link in the JavaScript sources there:

ln -s <MJ3-PATH> mathjax3

For the remainder we assume that this symlink has been set.

Getting the Lab to work

You need to install the MathJax context menu first:

nmp install mj-context-menu

Create a symbolic link for the context menu. MathJax expects it to be in parallel to its code.

ln -s node_modules/mj-context-menu

Then run the lab by loading v3-lab.html in your webbrowser via a local webserver. E.g., create a symbolic link

sudo ln -s <MathJax-dev-PATH> /var/www/html/

Run the lab on localhost using the URL

http://localhost/MathJax-dev/v3-lab.html

Or alternatively serve directly from the directory, i.e., by running a python server:

python -m SimpleHTTPServer 8000

and then run the lab at the following URL

http://localhost:8000/v3-lab.html

Running Samples

Samples are small scripts to test various MathJax features or to use MathJax directly for a specific purpose. They are particularly useful to work with local MathJax variants or test changes to the code base directly. Samples can be run using node or in a browser.

Running Samples in Node

Samples are run in node using the esm package on load. You need to first install esm by

npm install esm

The general command to run scripts is then:

node -r esm samples/<SCRIPT>.js <INPUT>

As example consider the script to parse LaTeX expressions into MathML:

node -r esm samples/tex2mml.js x^2

<math display="block">
  <msup>
    <mi>x</mi>
    <mn>2</mn>
  </msup>
</math>

Running Samples in a Browser

Samples can be run in the browser using the load.html page. This either loads the main.js file or the particular sample file given in the parameters. For example, running

http://localhost/v3-dev/load.html?samples/asciimath-document.js

will give you a rendered page of AsciiMath expressions in the browser. Note, that the output will also be displayed on the console. In fact, many scripts will only produce console output. For example, the URL:

http://localhost/v3-dev/load.html?samples/tex2mml.js&x^2

will print the corresponding MathML expression in the console:

<math display="block">
  <msup>
    <mi>x</mi>
    <mn>2</mn>
  </msup>
</math>

Scripts

Sample names should be self-explanatory.

samples/asciimath-document.js
samples/asciimath-json.js
samples/asciimath2mml-component.js
samples/asciimath2mml.js
samples/asyncLoad.js
samples/bits.js
samples/css.js
samples/find-asciimath.js
samples/find-mml.js
samples/find-strings.js
samples/find-tex-dollars.js
samples/find-tex.js
samples/html-full.js
samples/mfenced.js
samples/mml-bbox.js
samples/mml-nodes.js
samples/mml2html.js
samples/mml2svg.js
samples/notagids.js
samples/tag-format.js
samples/tex-document.js
samples/tex-json.js
samples/tex-multi-document.js
samples/tex-nodes.js
samples/tex-string.js
samples/tex2html.js
samples/tex2mml-component.js
samples/tex2mml-require.js
samples/tex2mml-speech.js
samples/tex2mml.js

The following two scripts need jsdom package for testing:

samples/test-adaptor.js
samples/test-styles.js
