[slime-devel] Native Win32 XEmacs w/ cygwin CLisp

[49gu4n502 at sneakemail.com]

Background: I'm just starting out with SLIME, and it's been just a little 
bit rough because of my environment, but more promising than ILisp. The 
complications are: I'm running on WinXP, I've generally used a native 
version of XEmacs (21.4.13 as of today), I use some Cygwin tools, and since 
I'm just getting reacquainted with Lisp, I've been trying out various 
implementations.

I tried out Cygwin XEmacs over the last week, but found it less stable 
overall than the native version, so I've reverted. I did get SLIME going 
with Cygwin XEmacs and Cygwin CLisp (latest version), no problem. When I 
switched back to native XEmacs, I had problems with SLIME initialization. 
XEmacs is sending native file namestrings to CLisp, and the latter chokes 
on the backslashes.

After only a little searching, I found 
slime-translate-to-lisp-filename-function, and now I define it as follows 
during XEmacs initialization:

  (defvar slime-translate-to-lisp-filename-function
    (function (lambda (s) (replace-in-string s "\\\\" "/"))))

However, I have found and fixed two places in slime.el that weren't calling 
this function. These two changes allow me to get to REPL. The functions 
that I changed are slime-maybe-start-lisp and slime-start-swank-server. 
Here's output from cvs diff:

diff -r1.228 slime.el
968c968
<                                 (concat slime-path slime-backend)))
---
>                                 (slime-to-lisp-filename (concat 
slime-path sli
me-backend))))
980c980
<                               (slime-swank-port-file))))
---
>                               (slime-to-lisp-filename 
(slime-swank-port-file))
)))


(If there's a better format I can use for showing changes, please tell me 
how to get it.)

Nice code, by the way, it only took a little guesswork to find the hook for 
translating file names. Very different from my ILisp experience.
