Katex: [auto-render] add an option to ignore \$ outside of latex expressions

Created on 10 Feb 2016 · 14Comments · Source: KaTeX/KaTeX

If it's possible for escaping \$ to normal $, then latex $ (expressions) $ would not be any problem.
I wanted to make my own hack for this, but I'm not used to string so far.
Is there any plan to support dollar sign escaping?

Rendering this text:

I will give you \$2 if you can solve $y = x^2$.

with this delimiter:

{ left: '$', right: '$', display: false }

results in

<#text>I will give you \</#text>
<span>KATEX MATH</span>
<#text>y = x^2</#text>
<#text>$.</#text>

where <#text> denotes a text DOM node.

We already have logic that should skip over backslashes:

Maybe it's not working?

That only works for escaping $ inside of math, but not outside of it. @PaulSohn can you give an example of what you're trying to do?

Agreed, can not write dollar sign outside of math equations...

@PaulSohn can you use different delimiters, e.g. $,$ and \[,\]?

I'm going to close this since it's going to be very difficult to implement something that handles the different behaviors people want. Also, there is a workaround by using different delimiters.

Just a question, How can I make the following string be ignored by katex?

John bought a shirt, a pair of pants, and a pair of shoes, which cost $10, $20, and $30, respectively. What percent of the total expense was spent for the pants?

It is being rendered like this:

There is more than one way to do this. If you are using the KaTeX auto-render extension, then you can delimit your math with $…$ instead of $…$ . Or you can nest the whole phrase in <noscript>…</noscript> tags.

Some markdown parsers only recognize the closing $ as a math delimiter if it is not followed by a number. Sometimes I think we should do that too.

Thanks for replying. I simply replaced my $ with <span>$</span> and this made Katex ignore it. I'm putting it out so that someone else also tries it if they're stuck.

Would be nice for MathJax processEscapes compatibility: http://docs.mathjax.org/en/latest/options/preprocessors/tex2jax.html#configure-tex2jax
