But then the question become if we want to provide a unified mechanism to parse mathematical formulas, e.g. from the TeXmacs format to an abstract form which could then used to create expression in some target language (scheme, mathemagix, Python, etc...) for evaluation. > > We already have such a mechanism. > It is used by each plug-in that supports mathematical input. Yes I know. But I do not understand how to manipulates with that mechanism parts of the formulas which are strings "a+b". That is why I was thinking a full parsing would be useful. > >> Thanks, I will give a look to the parsing support. I looked already in the C++ code but I do not understand how to extract a syntax tree from the parsing execution, it seems that it returns only whether the formula can be parsed. > > We would need to add productions to the parser and our grammars. > That is what I planned to do one day, when I would have time. > Well, somebody else could do it. :) It is not clear to me what would be a nice API to implement. Do you have already some ideas/references? Best Max _______________________________________________ Texmacs-dev mailing list [email protected] https://lists.gnu.org/mailman/listinfo/texmacs-dev
