itex2MML
-
In itex, inline equations are demarcated by $
$. Display equations are demarcated by $ $ $$ or \[ \]Should the itex2MML define these default delimiters?
-
In itex,
$pin$ is a single token, which is translated into <mi>pin</mi> in MathML.$p i n$ , on the other hand, is three tokens, which is translated into <mi>p</mi><mi>i</mi><mi>n</mi> in MathML. TeX makes no distinction between these two.The itex2MML extension must override MathJax.InputJax.TeX to treat multiple letters as a single variable.

It is possible (though probably not recommended) to insert MathML markup inside itex equations. So "<" and ">" are significant. To obtain a less-than or greater-than sign, you should use \lt or \gt, respectively.
MathJax supports \lt or \gt. It does not seem worth allowing MathML in TeX.
\begin{svg} ... \end{svg} allows you to embed snippets of SVG in itex equations. To assist in Instiki's LaTeX export feature, you can also include a graphicx command: \begin{svg} ... \end{svg} \includegraphics[width=...]{foo} where foo.pdf is a file containing a PDF version of the graphic. In itex, the \includegraphics command is defined as a NOOP, and the SVG is embedded in the MathML output. In Instiki's LaTeX export, the opposite is true: the svg environment is a NOOP, and the \includegraphics command is included in the output.
The itex2MML extension can define \includegraphics as a NOOP. Including SVG inside the TeX source might be a more difficult, cf for example the issue with \verb. For example, with itex2MML \begin{svg} <svg><text>\end{svg}</text> \end{svg} is an error and \begin{svg} <svg><text>\end{svg</text> \end{svg} generates invalid markup.
The itex2MML extension should implement the following array options:
\array
\arrayopts
\collayout (=\colalign),
\rowalign,
\align,
\eqcols,
\eqrows,
\collines,
\rowlines,
\frame,
\padding
\rowopts
\colalign,
\rowalign
\cellopts
\colalign,
\rowalign,
\rowspan,
\colspan
Missing commands: \Alpha, \Beta, \Zeta, \Eta, \Iota, \Kappa, \Mu, \Nu, \Pho, \Tau, \Upsi
All commands are supported.
Missing commands: \embedsin, \to, \nearr, \nwarr, \searr, \swarr, \neArrow \nwArrow \seArrow \swArrow, \darr, \uparr, \downuparrow \leftsquigarrow, \curvearrowbotright, \righttoleftarrow, \lefttorightarrow
\xrightarrow and \xmapsto are supported by the extpfeil extension. The itex2MML extension can implement other commands similarly.
Missing commands: \lang and \rang
Missing commands:
\bottom \minusb \plusb \timesb \intersection \union \VDash \nequiv \notni \invamp \Del \odash \Perp \sslash \nsubset \nsupset \qed \coloneqq \Coloneqq \coloneq \Coloneq \eqqcolon \Eqqcolon \eqcolon \Eqcolon \colonapprox \Colonapprox \colonsim \Colonsim \dblcolon
In keeping with AMSLaTeX, rather than MathML's conventions, \smallsetminus is designated as a small (non-stretchy) reverse solidus, \backslash is a reverse solidus. \setminus is stretchy.
The itex2MML extension should modify the MathJax's default behavior.
Missing command: \infinity
Missing command: \udots
Missing commands: \Union, \Intersection, \Oplus, \Otimes, \bigsqcap, \biginterleave, \Wedge, \Vee, \coproduct
Missing commands: \textsize, \scriptscriptsize, \mathfr
Missing commands: \medspace, \thickspace, \negspace, \mathrlap, \mathllap, \mathclap
Missing commands: \closure, \widebar, \widevec, \widecheck, \slash
Missing commands: \underoverset, \tensor, \multiscripts, \mathraisebox
itex2MML does its best to intelligently parse what's a number and what's not. Unfortunately, conventions for things like decimal markers are very culture-dependent, and incompatibly-so. If you don't like the way itex2MML parses the would-be numbers in your input, you can force it to interpret a certain string as a number, using the \itexnum{} command.
The extension should modify the number parsing and add the \itexnum command.
\color is already supported with the color extension. Missing command: \bgcolor
Missing commands: \statusline, \tooltip.
\toggle is implemented differently (as a 2-parameters command).
