The tex2jax Preprocessor doesn't work!

ystreibel commented 6 years ago

Hi, this is the configuration and the test that I try to do but doesn't work for me.

const mathjaxNode = require('mathjax-node');
mathjaxNode.config({MathJax: {tex2jax: {inlineMath: [ ['$','$'], ['\\(','\\)'] ],processEscapes: true}}});

mathjaxNode.typeset({
                                    math: ''$ d = a \left( \eta _0 \right) \Delta \eta $'',
                                    format: "inline-TeX",
                                    svg: true,
                                    html: true
                                }, (data) => {
                if (!data.errors) {
                    label.displayLabel = data.html;
                    label.image = {
                        data: 'data:image/svg+xml;base64,' + Buffer.from(data.svg).toString('base64'),
                        contentType: 'image/svg+xml'
                    };
                }

And the result is for svg : $2Gmrc2$

Delimiter $ is not remove after the typeset.

What can I do to remove delimiter? Could I need to contribute for this project?

Mathjax-node expects a single expression without delimiters. You will need to remove them yourself beforehand.

But what about the MathJax configuration ?

mathjaxNode.config({MathJax: {tex2jax: {inlineMath: [ ['$','$'], ['\$','\$'] ],processEscapes: true}}});

But what about the MathJax configuration ?

It is ignored.

Ok! So, could you add this in a feature request?

Maybe fix the readme.md that say:

MathJax: { } // standard MathJax configuration options, see https://docs.mathjax.org for more detail.

because the project doesn't support all the MathJax features.
