*
|

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