missing spec for \href{}{} in latexwalker

[gamboz]

I think the spec for the macro \href might be missing from pylatexenc/latexwalker/_defaultspecs.py The following code gives error: it expects a node with two arguments, but gets a node with empty argnlist.

from pylatexenc.latex2text import LatexNodes2Text
latex = r"\href{a}{b}"
print(LatexNodes2Text().latex_to_text(latex))

Thanks for reporting this. In LaTeX, the URL-related commands (like \href, \url, and \email) parse their URL argument in a special fashion to deactivate any special characters (such as $, _ or ^). So to implement them in pylatexenc requires a little more work to ensure that the URL argument is always parsed verbatim. I'm pretty busy at the moment but I'll try to find some time soon to implement them.

[ suggestion, please feel free to ignore :) ] If you can change the parsing procedure based on the macro name, it might be a good idea also to ignore the second argument of \newcommands & co. As you know, these macro sometimes include the beginning or end of an environment, and the parser gets confused (as in \newcommand{\beq}{\begin{equation}}).

Yes, I'm planning to improve the parsing of \newcommand instructions, too :)
