Tex or mathml to Alttext

[Sri Krishnan]

Hi all,

I am trying to generate TeX to mathml and Alt text using "MathJax-demos-node". I configured and installed all the dependencies. I run the following command in CMD. MathML produces correctly. But Alt-text not generated. I have tried all the possibilities by googling it, but no success.

i encountered following errors:

Unable to load locale: base
Unable to load locale: en
Something went wrong computing speech.

Can any one help me in this regard?

C:\MathJax-demos-node\speech>node -r esm tex2mml "a^2+b^2"
Unable to load locale: base
Unable to load locale: en
Something went wrong computing speech.
<math xmlns="http://www.w3.org/1998/Math/MathML" display="block" data-semantic-speech="">
  <msup>
    <mi>a</mi>
    <mn>2</mn>
  </msup>
  <mo>+</mo>
  <msup>
    <mi>b</mi>
    <mn>2</mn>
  </msup>
</math>

The speech-rule-engine component for MathJax is getting the path to its json files wrong when run in Windows, due to Window's use of "\" for directory separator rather than the unix "/" separator.  If you edit the node_modules/mathjax-full/components/src/a11y/sre/sre_config.js file and change line 15 from

        path + '/base.json').replace(/\/base\.json$/, '');

to 

        path + '/base.json').replace(/\\base\.json$/, '');

(changing "\/" to "\\" in the replacement pattern) and that should take care of it for you.
