By default, the command M-x slime starts the program specified
with inferior-lisp-program. If you invoke M-x slime with
a prefix argument, Emacs prompts for the program which should be
started instead. If you need that frequently or if the command
involves long filenames it’s more convenient to set the
slime-lisp-implementations variable in your .emacs. For
example here we define two programs:
(setq slime-lisp-implementations
'((cmucl ("cmucl" "-quiet"))
(sbcl ("/opt/sbcl/bin/sbcl") :coding-system utf-8-unix)))
This variable holds a list of programs and if you invoke SLIME with
a negative prefix argument, M-- M-x slime, you can select a
program from that list. When called without a prefix, either the name
specified in slime-default-lisp, or the first item of the list will be used.
The elements of the list should look like
(NAME (PROGRAM PROGRAM-ARGS...) &key CODING-SYSTEM INIT INIT-FUNCTION ENV)
NAMEis a symbol and is used to identify the program.
PROGRAMis the filename of the program. Note that the filename can contain spaces.
PROGRAM-ARGSis a list of command line arguments.
CODING-SYSTEMthe coding system for the connection. (see slime-net-coding-system)x
INITshould be a function which takes two arguments: a filename and a
character encoding. The function should return a Lisp expression as a
string which instructs Lisp to start the Swank server and to write the
port number to the file. At startup, SLIME starts the Lisp process
and sends the result of this function to Lisp’s standard input. As
default, slime-init-command is used. An example is shown in
Loading Swank faster.
INIT-FUNCTIONshould be a function which takes no arguments. It is called after the connection is established. (See also slime-connected-hook.)
ENVspecifies a list of environment variables for the subprocess. E.g.
(sbcl-cvs ("/home/me/sbcl-cvs/src/runtime/sbcl"
"--core" "/home/me/sbcl-cvs/output/sbcl.core")
:env ("SBCL_HOME=/home/me/sbcl-cvs/contrib/"))
initializes SBCL_HOME in the subprocess.
