It would be great if you'd release the code. The more examples, the better, especially when they're "real world".

Why does the LISP_community ignores C++LISP?

Your question: Autodesk ignores the LISP community ?
But my question :Why does the LISP_community ignore the language C++LISP?
MyAnswer: i can not understand...........

Diagodose, No disrespect intended, but I think no one here in this forum cares for what you are peddling.  Keep your C++ lisp in the classifieds, maybe someone there cares.

Perhaps Diag was wasjust demonstrating the very reason, in a very subtle way: Autodesk has endeavored to divert attention away from autolisp, towards methods that can provide further income, to Autodesk. As John Walker commented two decades ago, the autodesk team did not have the amount of time or knowledge to make all the various 'tools' that the established CAD providers had, so integrated 'arcane' Lisp into the autocad, in 1986. Then ambitious users could do CAD, for far less money. For years it allowed faster 'work' and extended capabilities, allowing more, much more; maybe too much. Either way Diag, very, very subtle.

May be you need to make a better effort in "marketing", better communication, better redaction and explanations to the answers you post here,  posting some good documention, examples. Posting under a real name also should help.


I think that no body will care about a new programming language without a good reason to do it: better and easier sintaxis, performance improvements, a modern IDE (which AutoLISP has not), community support,  etc.


So, evaluate honestly if you have any hope to succeed trying to introduce a new programming language to the AutoCAD developers community. If you are trying to make money with this, please say it cristal clear, if you not, may be going to open source it's an alternative.
