remember, in order to preview mathjax in a markdown file with kannokanno/previm, we should insert
<script src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-MML-AM_CHTML' async></script>
in the head of ~/.cache/dein/repos/github.com/kannokanno/previm/preview/_/index.html,
and insert
if (needReload && (typeof getContent === 'function') && (typeof getFileType === 'function')) {
var beforePageYOffset = _win.pageYOffset;
_doc.getElementById('preview').innerHTML = transform(getFileType(), getContent());
mermaid.init();
Array.prototype.forEach.call(_doc.querySelectorAll('pre code'), hljs.highlightBlock);
autoScroll('body', beforePageYOffset);
style_header();
>
/* Mathjax Start */
MathJax.Hub.Config({ tex2jax: { inlineMath: [['$','$'], ["\\(","\\)"]] } }); // added1
MathJax.Hub.Queue(["Typeset",MathJax.Hub]); //added2
autoScroll('body');
/* Mathjax End */
}
in the function loadPreview() which is located at ~/.cache/dein/repos/github.com/kannokanno/previm/preview/_/js/previm.js
remind also that we should execute :call dein#recache_runtimepath() to clear the cache (if you use dein)
