tex2jax, $ delimiters might ignore escaped \$

[pkra]

Via the AMS. With processEscapes:true, e.g., this

<p> \$1 -- \$2 -- \$3 -- $4 -- \$5 -- \$6</p>

is turned into

<p> $1 -- $2 -- $3 -- $4 -- \$5 -- \$6</p>

I'm guessing tex2jax starts lookin for another $ to match $4, reaches the end of the text node, realizes it can stop and never goes back to convert the escaped \$.

Would you consider this a bug?

Yes, that is what is happening. I guess it probably should be considered a bug.

This can be resolved by changing line 169 to

      if (this.search.matched) {
        element = this.encloseMath(element);
      } else if (!this.search.start) {
        element = this.scanText(this.search.open, this.search.opos + this.search.olen);
      }

while adding a parameter pos to the scanText() method, and changing line 163 to

      this.pattern.lastIndex = pos || 0;

The corresponding lines in asciimath2jax.js also should be changed.

Thanks, Davide.

No problem. It looks like I will be putting together a 2.7.4 release (for within the next two weeks). If you have anything else in the hopper that you haven't reported, let me know.
