***********************
|
||
|
|
The TeX input processor
|
||
|
|
***********************
|
||
|
|
|
||
|
|
The options below control the operation of the TeX input processor
|
||
|
|
that is run when you include ``"input/TeX"`` in the `jax` array of
|
||
|
|
your configuration. They are listed with their default values. To
|
||
|
|
set any of these options, include a ``TeX`` section in your
|
||
|
|
:meth:`MathJax.Hub.Config()` call. For example
|
||
|
|
|
||
|
|
.. code-block:: javascript
|
||
|
|
|
||
|
|
MathJax.Hub.Config({
|
||
|
|
TeX: {
|
||
|
|
Macros: {
|
||
|
|
RR: '{\\bf R}',
|
||
|
|
bold: ['{\\bf #1}', 1]
|
||
|
|
}
|
||
|
|
}
|
||
|
|
});
|
||
|
|
|
||
|
|
would set the ``Macros`` configuration option to cause two new macros
|
||
|
|
to be defined within the TeX input processor.
|
||
|
|
|
||
|
|
.. describe:: TagSide: "right"
|
||
|
|
|
||
|
|
This specifies the side on which ``\tag{}`` macros will place the
|
||
|
|
tags. Set it to ``"left"`` to place the tags on the left-hand side.
|
||
|
|
|
||
|
|
.. describe:: TagIndent: ".8em"
|
||
|
|
|
||
|
|
This is the amount of indentation (from the right or left) for the
|
||
|
|
tags produced by the ``\tag{}`` macro.
|
||
|
|
|
||
|
|
.. describe:: MultLineWidth: "85%"
|
||
|
|
|
||
|
|
The width to use for the `multline` environment that is part of
|
||
|
|
the ``AMSmath`` extension. This width gives room for tags at
|
||
|
|
either side of the equation, but if you are displaying mathematics
|
||
|
|
in a small area or a thin column of text, you might need to change
|
||
|
|
the value to leave sufficient margin for tags.
|
||
|
|
|
||
|
|
.. describe:: Macros: {}
|
||
|
|
|
||
|
|
This lists macros to define before the TeX input processor begins.
|
||
|
|
These are name:value pairs where the `name` gives the name of the TeX
|
||
|
|
macro to be defined, and `value` gives the replacement text for the
|
||
|
|
macro. The `value` canbe an array of the form `[value,n]`, where
|
||
|
|
`value` is the replacement text and `n` is the number of parameters
|
||
|
|
for the macro. Note that since the `value` is a javascript string,
|
||
|
|
backslashes in the replacement text must be doubled to prevent them
|
||
|
|
from acting as javascript escape characters.
|
||
|
|
|
||
|
|
For example,
|
||
|
|
|
||
|
|
.. code-block:: javascript
|
||
|
|
|
||
|
|
Macros: {
|
||
|
|
RR: '{\\bf R}',
|
||
|
|
bold: ['{\\bf #1}', 1]
|
||
|
|
}
|
||
|
|
|
||
|
|
would ask the TeX processor to define two new macros: ``\RR``,
|
||
|
|
which produces a bold-face "R", and ``\bold{...}``, which takes one
|
||
|
|
parameter and set it in the bold-face font.
