non-equations

[shashi]

trying to use this in Escher and running into problems because of the surrounding $s. Some parsers don't like it:

Uncaught ParseError: KaTeX parse error: Unexpected character: '$' at position 0: ̲$a+b=c$

What's the best way to work around this? The dirty way is to remove the extra $s, the nice way I think maybe is to have both LaTeXEquation and LaTeXString types.

Which parser accepts LaTeX equations but not dollar signs?

You could always strip off the $ characters when you pass it to such a parser. That seems just as easy as having a second type. Easier, because you can still use the L"..." prefix.

Yeah, I think that's what we'll do, thanks. Should it strip out $s at the end or all $s (not sure if there's any use for that in LaTeX equations)?

Looks like KaTeX only accepts equation inputs, so doesn't need $s.

If it only accepts equation inputs, all of the strings should start and end with $ and so you should just strip out the beginning and ending $ (and throw an error if the beginning and ending characters are not $). Potentially a LaTeX equation could contain a literal \$, so you wouldn't want to strip out every $.

Ok, thanks!

Maybe it is useful to have an equationstring(s::LaTeXString) function in LaTeXString that does this? A PR would be welcome.
