I think it's interesting how he never explicitly says that he forked Gosling Emacs (I think that's what he did, but if not please correct me!). "Therefore, when I wrote my second implementation of Emacs, I followed the same kind of design...Now, this [GNU Emacs] was not the first Emacs that was written in C and ran on Unix. The first was written by James Gosling, ... I discovered that Gosling's Emacs did not have a real Lisp. It had a programming language that was known as ‘mocklisp’, which looks syntactically like Lisp, but didn't have the data structures of Lisp... I concluded I couldn't use it [it here means mocklisp, but can be confused to mean Gosling Emacs] and had to replace it all, the first step of which was to write an actual Lisp interpreter. I gradually adapted every part of the editor based on real Lisp data structures, rather than ad hoc data structures, making the data structures of the internals of the editor exposable and manipulable by the user's Lisp programs...This second Emacs program was ‘free software’ in the modern sense of the term" Perhaps I'm reading too much into it. |
