The first LispLanguage compiler was developed by JohnMcCarthy at Dartmouth College between 1955 and 1959. This makes it the second oldest programming language in common use today (only Fortran is older, developed between 1954 and 1957). Lisp went forth and grew many many dialects: the most notable of these are AutoLisp, EmacsLisp, Interlisp, MacLisp, Scheme and Common Lisp.
Around 1980, there were many dialects of Lisp in development: Interlisp at Xerox, MacLisp, Lisp Machine Lisp and NIL (“New Implementation of Lisp”) at MIT, Portable Standard Lisp, SpiceLisp? at CMU, S-1 Lisp at Stanford and others. There was clearly a need for a standard. RichardGabriel?, JonWhite?, GuySteele and DavidMoon? were the driving force behind the standardization effort, which resulted in 1984 in GuySteele’s book CommonLispTheLanguage which set out a design for the new language CommonLisp; in 1986 the ANSI standardization committee (X3J13) was working; and in 1994 the ANSI CommonLisp standard was released. By the late 1990s, most commercial Lisp vendors had adopted CommonLisp. (AutoLisp remains a holdout.)
See http://www.lisp.org/ for a list of free and proprietary implementations for different platforms.
Changing Emacs to use CommonLisp would require a number of significant and incompatible changes, most notably:
I am willing to consider a small number of functions for inclusion as standard parts of Emacs. I don't have time to consider a large number, and I can't agree to them without considering them.
I do not like the Common Lisp style of using keyword arguments for many common functions. I basically do not have a very high opinion of many of the decisions that were made in Common Lisp.
Emacs has a simple interface to a running Lisp top-level. Use
‘M-x run-lisp’. This will run the
‘lisp’ program on your system. See the (emacs)Running an External Lisp. node of the EmacsManual for details.
If your program is not called
‘glisp’ or whatever, customize the option
See elisp.lisp for the code.
