Incorrect conversion of mathtools symbols like \coloneq and \Coloneq

[fiveseven-lambda]

Hello,

I have noticed that LaTeXML currently converts certain symbols from the mathtools package incorrectly. Specifically, the following conversions are observed:

• \coloneq is converted to :-
• \eqcolon is converted to -:
• \Coloneq is converted to ::-
• \Eqcolon is converted to -::

However, in the actual mathtools package, these symbols are converted as follows:

• \coloneq should convert to :=
• \colondash should convert to :-
• \eqcolon should convert to =:
• \dashcolon should convert to -:
• \Coloneq should convert to ::=
• \Colondash should convert to ::-
• \Eqcolon should convert to =::
• \Dashcolon should convert to -::

It would be great if the LaTeXML implementation could be updated to match the mathtools package’s definitions.

Thank you for your attention to this issue.
