Convert MathSpan to MathML using e.g. camoy/amath or gjtorikian/mtex2MML

[aslakr]

For html (and odf and epub) it would be nice to be able to produce MathML as mentioned in fletcher/peg-multimarkdown#39

I.e. as an option, instead of wrapping TeX math for MathJax in

MultiMarkdown-5/src/html.c

Lines 334 to 352 in f2a0b9c

	case MATHSPAN:
	temp = strdup(n->str);
	if (temp[0] == '$') {
	temp[strlen(temp)-1] = '\0';
	if (temp[1] == '$') {
	temp[strlen(temp)-1] = '\0';
	g_string_append_printf(out, "<span class=\"math\">\\[%s\\]</span>",&temp[2]);
	} else {
	g_string_append_printf(out, "<span class=\"math\">\\(%s\\)</span>",&temp[1]);
	}
	} else if (temp[strlen(temp) - 1] == ']') {
	temp[strlen(temp) - 3] = '\0';
	g_string_append_printf(out, "<span class=\"math\">%s\\]</span>",temp);
	} else {
	temp[strlen(temp) - 3] = '\0';
	g_string_append_printf(out, "<span class=\"math\">%s\\)</span>",temp);
	}
	free(temp);
	break;

convert this to MathML.

In the original issue blahtex is mentioned, but doesn’t seem very active.

One very simple alternative might be to use amath, a peg-based AsciiMath to MathML converter. It’s only AsciiMath, so it might not be a good alternative for text that are based on TeX-like syntax, but the amath c/peg-code seem rather readable.

mtex2MML, which is a active fork of itex2MML, might be another alternative. It tries to be compatible with MathJax.

I'm open to including a TeX -> MathML converter if there is something reasonable to use. I'll take a look at the suggestions you made, but I have some other priorities that I need to finish up first (e.g. getting Composer v3 finished up. ;)
