NAME

       katex - fast, easy-to-use JavaScript library for TeX math rendering

SYNOPSIS

       cli [options]

OPTIONS

       -V, --version
              output the version number

       -d, --display-mode
              Render math in display mode, which puts the math in display style (so \int and \sum are large, for
              example), and centers the math on the page on its own line.

       -F, --format <type>
              Determines the markup language of the output.

       --leqno
              Render display math in leqno style (left-justified tags).

       --fleqn
              Render display math flush left.

       -t, --no-throw-on-error
              Render  errors  (in  the  color given by --error-color) instead of throwing a ParseError exception
              when encountering an error.

       -c, --error-color <color>
              A color string given in the format 'rgb' or 'rrggbb' (no #). This option determines the  color  of
              errors rendered by the -t option.

       -m, --macro <def>
              Define  custom macro of the form '\foo:expansion' (use multiple -m arguments for multiple macros).
              (default: [])

       --min-rule-thickness <size>
              Specifies a minimum thickness, in ems, for fraction lines, `\sqrt` top lines,  `{array}`  vertical
              lines,  `\hline`,  `\hdashline`,  `\underline`, `\overline`, and the borders of `\fbox`, `\boxed`,
              and `\fcolorbox`.

       -b, --color-is-text-color
              Makes \color behave like LaTeX's 2-argument \textcolor, instead  of  LaTeX's  one-argument  \color
              mode change.

       -S, --strict
              Turn  on  strict  / LaTeX faithfulness mode, which throws an error if the input uses features that
              are not supported by LaTeX.

       -T, --trust
              Trust the input, enabling all HTML features such as \url.

       -s, --max-size <n>
              If non-zero, all user-specified sizes, e.g. in \rule{500em}{500em}, will be capped to maxSize ems.
              Otherwise, elements and spaces can be arbitrarily large

       -e, --max-expand <n>
              Limit the number of macro expansions to the specified  number,  to  prevent  e.g.  infinite  macro
              loops. If set to Infinity, the macro expander will try to fully expand as in LaTeX.

       -f, --macro-file <path>
              Read macro definitions, one per line, from the given file.

       -i, --input <path>
              Read LaTeX input from the given file.

       -o, --output <path>
              Write html output to the given file.

       -h, --help
              display help for command
