Safari - regular expression

[amilich]

Looks like safari doesn't support lookbehind yet - any alternate regex for the math_inline input rule?

There's actually a simpler regex commented out in the code that avoids using lookbehinds, but you will lose the ability to escape $ symbols with \$.

• Original /(?<!\\)\$(.+)(?<!\\)\$/
• Simplified /\$(.+)\$/

In the future, I'll probably look for a more cross-browser-friendly way to escape.

Thank you! I've actually been testing with /[^\\]?\$([^$\n\\]+)[^\\][\$]/, which seems to work okay, and then adding 1 to start inside replaceRangeWith if the match starts with a space. Probably could be cleaner.
