  8. *
  9. * This file implements a KaTeX version of mhchem version 3.3.0.
  10. * It is adapted from MathJax/extensions/TeX/mhchem.js
  11. * It differs from the MathJax version as follows:
  12. * 1. The interface is changed so that it can be called from KaTeX, not MathJax.
  13. * 2. \rlap and \llap are replaced with \mathrlap and \mathllap.
  14. * 3. Four lines of code are edited in order to use \raisebox instead of \raise.
  15. * 4. The reaction arrow code is simplified. All reaction arrows are rendered
  16. * using KaTeX extensible arrows instead of building non-extensible arrows.
  17. * 5. \tripledash vertical alignment is slightly adjusted.
  18. *
  19. * This code, as other KaTeX code, is released under the MIT license.
