Enabling dollar delimiter for inline math

[za...@klacto.net]

Hi,

My pages use MathJax by means of the scripts line

<script type="text/javascript"
src="/static/mathjax/MathJax.js?config=TeX-AMS_HTML"></
script>

Wishing to enable dollar delimiters for inline math mode, I have tried
to modify the file MathJax/config/TeX-AMS_HTML.js by changing the line
that starts

MathJax.Extension.tex2jax={version:"1.1.3",config:{inlineMath:[["\\
(","\\)"]],displayMath: (etc.)

into

MathJax.Extension.tex2jax={version:"1.1.3",config:{inlineMath:
[['$','$'],["\\(","\\)"]],displayMath: (etc.)

but I still see no effect ("$f$" gets rendered simply as itself).

What am I doing wrong?

Please read the documentation at http://docs.mathjax.org/en/latest/tex.html#tex-and-latex-math-delimiters for how to do that.

You should not edit the config files that MathJax ships with. (But you can writer your own or modify a copy.)

Thanks Peter. Actually what I did was working, I had only neglected to
clear my browser's cache.

I had also read the doc you suggest, (although in the version
http://docs.mathjax.org/en/v1.1-latest/tex.html), and I wholeheartedly
agree with you for preferring to have a personal configuration file,
rather than edit the file shipped by MathJax. However, I don't know
how to include a personal configuration without editing TeX-
AMS_HTML.js. In fact, I saw that default.js has a hook for that:

MathJax.Hub.Config({

//
// A comma-separated list of configuration files to load
// when MathJax starts up. E.g., to define local macros, etc.
// The default directory is the MathJax/config directory.
//
// Example: config: ["local/local.js"],
// Example: config: ["local/local.js","MMLtoHTML.js"],
//
config: [],

but I found no such provision in TeX-AMS_HTML.js. How am I to proceed?
Does this mean that I should make my own config file and have *that*
include TeX-AMS_HTML.js?

Thanks again,
Francois Z.

ah, glad it worked out. 

If you the TeX-AMS_HTML basically serves your purpose (input-output-wise), then just put your personal configuration (delimiters, TeX-macros etc) in a separate file.

MathJax can load multiple configuration files. The instructions at http://docs.mathjax.org/en/latest/configuration.html#using-a-local-configuration-file-with-the-cdn work also with any other installation of MathJax (not just with the CDN).

Hope this helps.

Peter.

Some confusion is possible over the interaction between invoking a
default configuration and configuration lines added to change tokens
and the like. The examples all suggest that a line like
inlineMath: [['$','$'], ['\\(','\\)']],
will replace in toto all prior inlineMath statements for tex2jax, for
example, but I don't think this is expressed in so many words. In
other words, if you want to add @i to the list of tokens employed, you
have to list all the token you wish to use in the inlineMath
configuration statement, not just the tokens you wish to add.

Also, I noticed that the asciimath2jax parameters are not parallel to
delimiters for tex2jax in that the former requires a 'delimiter'
statement and then allows for inlineMath or displayMath statements,
while the latter omits the 'delimiter' statement. Why wouldn't these
use parallel structures?

AsciiMath doesn't distinguish between in-line and display math (it
only has one mode). So rather than have separate inlineMath and
displayMath delimiter arrays, it just has a "delimiter" array. But I
do see that the example in the documentation is in error (it shows
inlineMath rather than delimiters). That should be fixed.

Many thanks for the reference, Peter. That taught me about the in-line
configuration option, which turned out to be the most convenient for
my purposes.

No problem at all. Glad the documentation could help out.
