Jex - supported Latex

by David K. Levine

Jex expects latex fragments enclosed in brackets {} and treats $'s as \$'s

Macros that do not exist in standard Latex; Jex will always try to convert these to equivalent Latex macros before writing, so these should not ordinarily occur in Jex output

\leftgroup{} \rightgroup{} - groups of fence delimiters, for example \leftgroup{[} is equivalent to \left[

\overset{}{} - groups of embellishments set above, for example \overset{-}{a} is equivalent to \overline a

\underset{}{} - groups of embellishments set below, for example \underset{-}{a} is equivalent to \underline a

{} \overgroup{}{} - groups of horizontal division style delimiters, for example {a} \overgroup{-} {b} is equivalent to a \over b

\unicode{c-style-hex-string} - the unicode character refered to by hex-string

Treatment of functions

functions such as \log \sin and so forth are converted by Jex to \mathrm{log} \mathrm{sin}

Latex constructs supported in Jex

No non-mathematical constructs are supported, and support for some symbols is not yet implemented. When macros unknown to it are encountered, Jex will try to ignore them.

Supported

        \begin{align} \end{align}
        \begin{array} \end{array}
        &
        \\ recognized as an array delimiter, but comments are not supported
        \mathrm{}
        \, \: \; negative spaces are neither recognized nor implemented
        \left[{( \right]})
        \root[]{} recognized by the parser but not currently implemented in Jex
        \over
        superscripts and subscripts
        upper and lower case greek alphabet
        named functions
        embellishments both narrow and wide and underline
        all the symbols I know about except those listed below

Not Supported

        under and overbraces
        \frac
        \begin{math} \begin{display} \begin{equation} and the corresponding \end and the abbreviations \( \[
            these are essentially meaningless in Jex but the parser needs to do a better job of ignoring them
