Build

To build the distribution repository for the MathJax Accessibility extension, just call grunt with the default task.

npm install --only=dev && grunt

Note that this repository heavily depends on SRE

Build order as implemented in the Gruntfile

• Prep dist folder
• Clone speech-rule-engine
• Install npm dependencies for speech-rule-engine
• Run make mathjax in speech-rule-engine to build an optimized version
• Copy lib/sre_mathjax.js and lib/wgxpath.install.js to dist
• Copy subdirectories from src/mathmaps to dist
• JSON minify json files in mathmaps
• Minify src/mathmaps/mathmaps_ie.js to dist/mathmaps
• Minify extensions/\*.js to destination dist
• Copy invalid_keypress.mp3 and invalid_keypress.ogg to dist
• Clean up: remove speech-rule-engine folder

Generated files

The build process will generate the following files:

• The minified versions of the assistive technology extension files.
• The closure compiled version of the speech rule engine.
• A single file that combines all of the above.
• mathmaps_ie.js: File with JSON objects that is loaded by the speech rule engine if it runs on IE or Edge.
• mathmaps: JSON files that are loaded by the speech rule engine if it runs in any other browser or environment.
• wxpath.install.js: A copy of wicked-good-xpath for use in IE and Edge.
