[slime-devel] suggestion for ~/.slime/fasl/*
Some lisp implementation can be run on different architectures. If users keep the same home on different computers this will lead to collision in ~/.slime/fasl/* directories. To generate the directory name for fasl files, I use the following function, adding the machine type: (defun first-word (text) (let ((pos (position (character " ") text))) (if pos (subseq text 0 pos) text))) (defun implementation-id () (format nil "~A-~A-~A" (first-word (lisp-implementation-type)) (first-word (lisp-implementation-version)) (first-word (machine-type))));;implementation-id -- __Pascal Bourguignon__ http://www.informatimago.com/ Voting Democrat or Republican is like choosing a cabin in the Titanic.

OK, but more interesting is what the proposed implementation-id function returns.
Sure: "CLISP-2.33-PC/386" (win32) vs "CLISP-2.33-I686" (cygwin) So Pascal's version does work fine for our the current case. The second word from (lisp-implementation-version) is also a hint => "2.33 (2004-03-17) (built 3288528537) (memory 3304787349)" but also quite fragile. Whenever Sam build the cygwin and native version at the same day it will fail. Sam should know which function is better to get the at the build_os string. (machine-version) is almost the same. (just "PC/686" for win32) (machine-instance) doesn't help since both are the same. -- Reini Urban http://xarch.tu-graz.ac.at/home/rurban/

What about (software-type) and (software-version)? Cheers, -- Nikodemus Schemer: "Buddha is small, clean, and serious." Lispnik: "Buddha is big, has hairy armpits, and laughs."

not much better. you may now guess which is which. hint: prompt. $ clisp-base -norc -x "(software-version)" "GNU C 3.3.3 (cygwin special)" $ clisp-base -norc -x "(software-type)" "gcc -W -Wswitch -Wcomment -Wpointer-arith -Wimplicit -Wreturn-type -Wno-sign-compare -O2 -fexpensive-optimizations -DUNICODE -DDYNAMIC_FFI -I. -x none -lintl libcharset.a libavcall.a libcallback.a -lreadline -lncurses -liconv -L/usr/local/lib -lsigsegv -L/usr/X11R6/lib -lX11 SAFETY=0 HEAPCODES STANDARD_HEAPCODES SPVW_PAGES SPVW_MIXED"

just removing the "/" from the (machine-type) is needed. for clisp windows afaik. -- Reini Urban http://xarch.tu-graz.ac.at/home/rurban/

Some lisp implementation can be run on different architectures.
If users keep the same home on different computers this will lead to collision in ~/.slime/fasl/* directories.
Talking about that, SLIME obviously made his own way to solve this problem. I wonder if you can do that using ASDF? That is, generating fasl file into a "build" directory and not into the root of your project. It's really really annoying. I guess ASDF is enough extensile to do that, but the lack of doc make it difficult to extend. -- Frederic Brunel
