将 LaTeX 转换成 MathJax

hbghlyj

tex.stackexchange.com/questions/68916/convert … atex-to-mathjax-html
在命令行执行
make4ht filename.tex "mathjax"
发现有一些不足之处:
tikzcd没有转换成svg,而mathjax也不支持...
解决办法...再执行一次,不加"mathjax"这个参数,将得到的svg图逐个手动插入html
tikz画的图里面的\hyperlink转换后丢失
解决办法...在svg代码中逐个手动插入链接
mathjax不支持intertext见github.com/mathjax/MathJax/issues/736
解决办法:手动逐个将\intertext{TEXT}换成\end{xxx} TEXT \begin{xxx}
脚注会放到不同的文件里
解决办法:用脚本批量合并它们
github.com/michal-h21/make4ht
make4ht -u -f html5+mjcli filename.tex "mathjax" "fn-in"
使用"fn-in"这样就可以把脚注放到同一个html文件里了

MathJax does NOT implement \lefteqn But you could define your own version

1. \def\lefteqn#1{\rlap{\displaystyle{#1}}}

Copy the Code

latexref.xyz/eqnarray.html
webhome.phy.duke.edu/~rgb/General/latex/lefteqn.html
eqnarray 环境提供了 \lefteqn 命令，可以在公式的等号左边部分过长时使用。示例：

1. \begin{eqnarray*}
2.     \lefteqn{a + b + c + d + e + f + g + h} \\
3.     & = & i + j + k + l + m \\
4.     & = & n + o + p + q + r + s
5. \end{eqnarray*}
7. \begin{eqnarray*}
8.     \lefteqn{a + b + c + d + e + f + g + h} \\
9.     & = & i + j
10. \end{eqnarray*}

Copy the Code

输出：

等号右边部分过短时公式可能不会居中。

How to use textup with MathJax?

1. \let\textup\textrm

Copy the Code

\textnormal command is not supported
Note that \textrm is defined in MathJax as a macro, and it calls on \text internally.
The \textnormal→\textrm does not make much sense for the reasons that \textnormal is more like \text in matching the "surrounding environment" in MathJax.

1. \let\textnormal\textrm

Copy the Code

using Big operator with Times does not work

1. \def\bigtimes{\mathop{\vcenter{\huge\times}}}

Copy the Code

Mathjax does not recognize \prescript
MathML has a prescripts mechanism using <mmultiscripts> and <mprescripts> so in MathJaX you also have the possibility of directly accessing those rather than relying on conversion from some "standard" LaTeX package markup. You can generate any MatHML element from the TeX MathJax syntax using \mmlToken
make \sideset more strict

1. \newcommand{\sideset}[3]{\mathop{\vphantom{#3}}\nolimits#1\!#3\nolimits#2}

Copy the Code

simple stmaryrd extension

1. \def\mapsfrom{\mathrel{\unicode{8612}}}

Macro: arc symbol under, over

1. \overset{\mmlToken{mo}{&#x23DC;}}{XYZ}
2. \underset{\mmlToken{mo}{&#x23DD;}}{XYZ}

Copy the Code

左括弧$\lparen$的代码是\lparen
左竖杠$\lvert$的代码是\lvert
左双竖杠$\lVert$的代码是\lVert
左方括号$\lbrack$的代码是\lbrack
左花括号$\lbrace$的代码是\lbrace
左尖括号$\langle$的代码是\langle
左地板号$\lfloor$的代码是\lfloor
左天花板$\lceil$的代码是\lceil
左胡须号$\lmoustache$的代码是\lmoustache
要打出右括号统一把 l 改为 r 即可
$\left<1\over2\right>$的代码是\left<1\over2\right>
$\left/1\over2\right/$的代码是\left/1\over2\right/
还可以用\DeclarePairedDelimiter、\DeclarePairedDelimiterX、\DeclarePairedDelimiterXPP自定义
其中mathtools extension定义了\lparen
Easily change behavior of \DeclarePairedDelimiter

把latex转换成html啊,然后就可以发布到网上
