Loading and Configuring MathJax
|
|
*******************************
|
|
|
|
You load MathJax into a web page by including its main JavaScript file
|
|
into the page. That is done via a ``<script>`` tag that links to the
|
|
``MathJax.js`` file. Place the following line in the ``<head>``
|
|
section of your document:
|
|
|
|
.. code-block:: html
|
|
|
|
<script type="text/javascript" src="path-to-MathJax/MathJax.js"></script>
|
|
|
|
where ``path-to-MathJax`` is replaced by the URL of the MathJax
|
|
directory on your server, or (if you are using MathJax locally rather
|
|
than through a server) the location of that directory on your hard
|
|
disk. For example, if the MathJax directory is at the top level of
|
|
your web server's directory hierarchy, you might use
|
|
|
|
.. code-block:: html
|
|
|
|
<script type="text/javascript" src="/MathJax/MathJax.js"></script>
|
|
|
|
to load MathJax.
|
|
|
|
Although it is possible to load MathJax from a site other than your
|
|
own web server, there are issues involved in doing so that you need to
|
|
take into consideration. See the :ref:`Notes About Shared Servers
|
|
<cross-domain-linking>` for more details. Please do **not** link to
|
|
the copy of MathJax at ``www.mathjax.org``, as we do not have the
|
|
resources to act as a web service for all the sites on the web that
|
|
would like to display mathematics. If you are able to run MathJax
|
|
from your own server, please do so (this will probably give you better
|
|
response time in any case).
|
|
|
|
It is best to load MathJax in the document's ``<head>`` block, but it
|
|
is also possible to load MathJax into the ``<body>`` section, if
|
|
needed. If you do this, load it as early as possible, as
|
|
MathJax will begin to load its components as soon as it is included in
|
|
the page, and that will help speed up the processing of the
|
|
mathematics on your page. MathJax does expect there to be a
|
|
``<head>`` section to the document, however, so be sure there is one
|
|
if you are loading MathJax in the ``<body>``.
|
|
|
|
It is also possible to load MathJax dynamically after the page has
|
|
been prepared, for example, via a `GreaseMonkey
|
|
<http://www.greasespot.net/>`_ script, or using a specially prepared
|
|
`bookmarklet <http://en.wikipedia.org/wiki/Bookmarklet>`_. This is an
|
|
advanced topic, however; see :ref:`Loading MathJax Dynamically
|
|
<ajax-mathjax>` for more details.
|
|
|
|
|
|
Configuring MathJax
|
|
===================
|
|
|
|
There are several ways to configure MathJax, but the easiest is to use
|
|
the ``config/MathJax.js`` file that comes with MathJax. See the
|
|
comments in that file, or the :ref:`configuration details
|
|
<configuration>` section, for explanations of the meanings of the various
|
|
configuration options. You can edit the ``config/MathJax.js`` file to
|
|
change any of the settings that you want to customize. When you
|
|
include MathJax in your page via
|
|
|
|
.. code-block:: html
|
|
|
|
<script type="text/javascript" src="path-to-MathJax/MathJax.js"></script>
|
|
|
|
it will load ``config/MathJax.js`` automatically as one of its
|
|
first actions.
|
|
|
|
Alternatively, you can configure MathJax efficiently by calling
|
|
:meth:`MathJax.Hub.Config()` when you include MathJax in your page, as
|
|
follows:
|
|
|
|
.. code-block:: html
|
|
|
|
<script type="text/javascript" src="path-to-MathJax/MathJax.js">
|
|
MathJax.Hub.Config({
|
|
extensions: ["tex2jax.js"],
|
|
jax: ["input/TeX", "output/HTML-CSS"],
|
|
tex2jax: {
|
|
inlineMath: [ ['$','$'], ["\\(","\\)"] ],
|
|
displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
|
|
},
|
|
"HTML-CSS": { availableFonts: ["TeX"] }
|
|
});
|
|
</script>
|
|
|
|
This example includes the ``tex2jax`` preprocessor and configures it
|
|
to use both the standard TeX and LaTeX math delimiters. It uses the
|
|
TeX input processor and the HTML-CSS output processor, and forces the
|
|
HTML-CSS processor to use the TeX fonts rather that other locally
|
|
installed fonts (e.g., :term:`STIX` fonts). See the
|
|
:ref:`configuration options <configuration>` section (or the comments
|
|
in the ``config/MathJax.js`` file) for more information about the
|
|
configuration options that you can include in the
|
|
:meth:`MathJax.Hub.Config()` call. Note that if you configure MathJax
|
|
using this in-line approach, the ``config/MathJax.js`` file is **not**
|
|
loaded.
|
|
|
|
Finally, if you would like to use several different configuration
|
|
files (like ``config/MathJax.js``, but with different settings in each
|
|
one), you can copy ``config/MathJax.js`` to ``config/MathJax-2.js``,
|
|
or some other convenient name, and use
|
|
|
|
.. code-block:: html
|
|
|
|
<script type="text/javascript" src="path-to-MathJax/MathJax.js">
|
|
MathJax.Hub.Config({ config: "MathJax-2.js" });
|
|
</script>
|
|
|
|
to load the alternative configuration file ``config/MathJax-2.js``
|
|
from the MathJax ``config`` directory. In this way, you can have as
|
|
many distinct configuration files as you need.
|
|

|
Common Configurations
|
|
=====================
|
|
|
|
The following examples show configurations that are useful for some
|
|
common situations. This is certainly not an exhaustive list, and
|
|
there are variations possible for any of them. Again, the comments in
|
|
the ``config/MathJax.js`` file can help you decide what settings to
|
|
include, even if you are using the in-line configuration method.
|
|
|
|
The TeX setup
|
|
-------------
|
|
|
|
This example calls the ``tex2jax`` preprocessor to identify
|
|
mathematics in the page by looking for TeX and LaTeX math delimiters.
|
|
It uses ``$...$`` and ``\(...\)`` for in-line mathematics, while
|
|
``$$...$$`` and ``\[...\]`` mark displayed equations. Because dollar
|
|
signs are used to mark mathematics, if you want to produce an actual
|
|
dollar sign in your document, you must "escape" it using a slash:
|
|
``\$``. This configuration also loads the ``AMSmath`` and
|
|
``AMSsymbols`` extensions so that the macros and environments they
|
|
provide are defined for use on the page.
|
|
|
|
.. code-block:: javascript
|
|
|
|
MathJax.Hub.config({
|
|
extensions: ["tex2jax.js","TeX/AMSmath.js","TeX/AMSsymbols.js"],
|
|
jax: ["input/TeX","output/HTML-CSS"],
|
|
tex2jax: {
|
|
inlineMath: [['$','$'],["\\(","\\)"]],
|
|
processEscapes: true,
|
|
},
|
|
});
|
|
|
|
Other extensions that you may consider adding to the `extensions`
|
|
array include: ``TeX/noErrors.js``, which shows the original TeX code
|
|
if an error occurs while processing the mathematics (rather than an
|
|
error message), ``TeX/noUndefined.js``, which shows undefined
|
|
macros names in red (rather than producing an error), and
|
|
``TeX/autobold.js``, which automatically inserts ``\boldsymbol{...}``
|
|
around your mathematics when it appears in a section of your page that
|
|
is in bold. Most of the other TeX extensions are loaded automatically
|
|
when needed, and so do not need to be included explicitly in your
|
|
`extensions` array.
|
|
|
|
See the :ref:`tex2jax configuration <configure-tex2jax>` section for
|
|
other configuration options for the ``tex2jax`` preprocessor, and the
|
|
:ref:`TeX input jax configuration <configure-TeX>` section for options
|
|
that control the TeX input processor.
|
|
|
|
|
|
The MathML setup
|
|
----------------
|
|
|
|
This example calls the ``mml2jax`` preprocessor to identify
|
|
mathematics in the page that is in :term:`MathML` format, which uses
|
|
``<math display="block">`` to indicate displayed equations, and
|
|
``<math display="inline">`` or simply ``<math>`` to mark in-line
|
|
formulas.
|
|
|
|
.. code-block:: javascript
|
|
|
|
MathJax.Hub.config({
|
|
extensions: ["mml2jax.js"],
|
|
jax: ["input/MathML","output/HTML-CSS"]
|
|
});
|
|
|
|
Note that this will work in HTML files, not just XHTML files (MathJax
|
|
works with both), and that the web page need not be served with any
|
|
special MIME-type. Also note that, unless you are using XHTML rather
|
|
than HTML, you should not include a namespace prefix for your
|
|
``<math>`` tags; for example, you should not use ``<m:math>`` except
|
|
in a file where you have tied the ``m`` namespace to the MathML DTD.
|
|
|
|
See the :ref:`mml2jax configuration <configure-mml2jax>` section for
|
|
other configuration options for the ``mml2jax`` preprocessor, and the
|
|
:ref:`MathML input jax configuration <configure-MathML>` section for
|
|
options that control the MathML input processor.
|
|
|
|
|
|
Both TeX and MathML
|
|
-------------------
|
|
|
|
This example provides for both TeX and MathML input in the same file.
|
|
It calls on both the ``tex2jax`` and ``mml2jax`` preprocessors and the
|
|
TeX and MathML input jax to do the job.
|
|
|
|
.. code-block:: javascript
|
|
|
|
MathJax.Hub.config({
|
|
extensions: ["tex2jax.js", "mml2jax.js"],
|
|
jax: ["input/TeX", "input/MathML", "output/HTML-CSS"],
|
|
});
|
|
|
|
Notice that no ``tex2jax`` configuration section is included, so it
|
|
uses its default options (no single dollar signs for in-line math).
|
|
|
|
The majority of the code for the TeX and MathML input processors are
|
|
not loaded until they are actually needed by the mathematics on the
|
|
page, so if this configuration is used on a page that include only
|
|
MathML, the TeX input processor will not be loaded. Thus it is
|
|
reasonably efficient to specify both input processors even if only one
|
|
(or neither one) is used.
|
|
|
|
|
|
TeX input with MathML output
|
|
----------------------------
|
|
|
|
This example configures MathJax to use the ``tex2jax`` preprocessor
|
|
and TeX input processor, but the choice of output format is determined
|
|
by MathJax depending on the capabilities of the users's browser. The
|
|
is performed by the ``MMLorHTML.js`` configuration file that is loaded
|
|
in the `config`` array.
|
|
|
|
.. code-block:: javascript
|
|
|
|
MathJax.Hub.Config({
|
|
config: ["MMLorHTML.js"],
|
|
extensions: ["tex2jax.js"],
|
|
jax: ["input/TeX"]
|
|
});
|
|
|
|
With this setup, Firefox or Internet Explorer with the `MathPlayer
|
|
plugin <http://www.dessci.com/en/products/mathplayer/>`_ installed
|
|
will use the NativeMML output processor, while all other browsers will
|
|
use the HTML-CSS output processor. Since native MathML support is
|
|
faster than MathJax's HTML-CSS processor, this will mean that the web
|
|
pages will display faster for Firefox and IE than they woudl
|
|
otherwise. This speed comes at the cost, however, as you are now
|
|
relying on the native MathML support to render the mathematics, and
|
|
that is outside of MathJax's control. There may be spacing or other
|
|
display differences (compared to MathJax's HTML-CSS output) when the
|
|
NativeMML output processor is used.
|
|
|
|
See :ref:`MathJax Output Formats <output-formats>` for more
|
|
information on the NativeMML and HTML-CSS output processors. See the
|
|
:ref:`MMLorHTML configuration <configure-MMLorHTML>` section for
|
|
details on the options that control the ``MMLorHTML`` configuration.
|
|
|
|
|
|
MathML input and output in all browsers
|
|
---------------------------------------
|
|
|
|
This example configures MathJax to look for MathML within your page,
|
|
and to display it using the browser's native MathML support, if
|
|
possible, or its HTML-CSS output if not.
|
|
|
|
.. code-block:: javascript
|
|
|
|
MathJax.Hub.Config({
|
|
config: ["MMLorHTML.js"],
|
|
extensions: ["mml2jax.js"],
|
|
jax: ["input/MathML"]
|
|
});
|
|
|
|
Using this configuration, MathJax finally makes MathML available in
|
|
all modern browsers.
|
|
|
|
See the :ref:`MMLorHTML configuration <configure-MMLorHTML>` section
|
|
for details on the options that control the ``MMLorHTML``
|
|
configuration file, the :ref:`MathML configuration <configure-MathML>`
|
|
section for the options that control the MathML output processor, and
|
|
the :ref:`mml2jax configuration <configure-mml2jax>` section for the
|
|
options that control the ``mml2jax`` preprocessor.
|
|
|
|

.. _configuration:
|
|
|
|
Configuration Objects
|
|
=====================
|
|
|
|
The various components of MathJax, including its input and output
|
|
processors, its preprocessors, its extensions, and the MathJax core,
|
|
all can be configured through the ``config/MathJax.js`` file, or via a
|
|
:meth:`MathJax.Hub.Config()` call (indeed, if you look closely, you
|
|
will see that ``config/MathJax.js`` is itself one big call to
|
|
:meth:`MathJax.Hub.Config()`). Anything that is in
|
|
``config/MathJax.js`` can be included in-line to configure MathJax.
|
|
|
|
The structure that you pass to :meth:`MathJax.Hub.Config()` is a
|
|
JavaScript object that includes name-value pairs giving the names of
|
|
parameters and their values, with pairs separated by commas. Be
|
|
careful not to include a comma after the last value, however, as some
|
|
browsers (namely Internet Explorer) will fail to process the
|
|
configuration if you do.
|
|
|
|
The MathJax components, like the TeX input processor, have their own
|
|
sections in the configuration object, labeled by the component name,
|
|
and using an configuration object as its value. The object is itself
|
|
a configuration object made up of name-value pairs that give the
|
|
configuration options for the component.
|
|
|
|
For example,
|
|
|
|
.. code-block:: javascript
|
|
|
|
MathJax.Hub.Config({
|
|
showProcessingMessages: false,
|
|
jax: ["input/TeX", "output/HTML-CSS"],
|
|
TeX: {
|
|
TagSide: "left",
|
|
Macros: {
|
|
RR: '{\\bf R}',
|
|
bold: ['{\\bf #1}',1]
|
|
}
|
|
}
|
|
});
|
|
|
|
is a configration that includes two settings for the MathJax Hub (one
|
|
for `showProcessingMessages` and one of the `jax` array), and a
|
|
configuration object for the TeX input processor. The latter includes
|
|
a setting for the TeX input processor's `TagSide` option (to set tags
|
|
on the left rather than the right) and a setting for `Macros`, which
|
|
defines new TeX macros (in this case, two macros, one called ``\RR``
|
|
that produces a bold "R", and one called ``\bold`` that puts is
|
|
argument in bold face).
|
|
|
|
The ``config/MathJax.js`` file is another example that shows nearly
|
|
all the configuration options for all of MathJax's components.
|
|
|
|
|
|
