[slime-devel] Splitting slime.el
by Sean O'Rourke 05 Apr '04

05 Apr '04

Right now slime.el is 6250 lines, which makes it one of the larger programming modes line-count-wise. Besides making byte-compilation frustratingly slow, this size hides useful sub-components that (IMHO) could be made into their own, separate modules and used outside of Slime. For example, once the Slime-specific evaluation code has been factored out, there's a nice generic Elisp REPL hiding in there. With a bit of work today, I was able to turn it into a serviceable 500-line tool for interactive Perl development. While I did away with the asynchronous I/O features for simplicity's sake, I imagine these could be kept with a bit more work. The Xref browser (which I've never seen in action, not having CMUCL at hand) could be a similarly useful component. The long-term upside of this is that many of the Slime interfaces, which are quite nice, could be used as a common face for other languages that support interactive development and introspection, like Perl, Python, and Ruby. The downside, of course, is that this would constrain Slime's development. However, since Slime is stable enough to have a manual now, this may not be such a problem. Opinions? /s

Here is the documentation for excl:arglist: arglist Arguments: function Returns two values: if the the argument list of the operator (function, generic function, or macro) specified by the argument is known, it and t are returned. If the argument list is not known (that information can be discarded to save space), nil and nil are returned. Note that some argument lists may be uninformative (perhaps simply &rest args) when a function does all argument processing within its body. Also, the compiler may have simplified the argument list for its purposes. This function is designed to assist only. The argument list returned, even when the second returned argument is t, may not accurately describe all valid lists of arguments that can be passed to the function. (For example, the &allow-other-keys lambda-list keyword is often dropped.) -- Bill Clementson

[slime-devel] Bad interaction between slime and repl variables in SBCL

Using the latest version of slime (2004-04-02), and SBCL 0.8.9.6, I get problems with repl variables.

[slime-devel] Automatic "semantic" indentation
by Luke Gorrie 05 Apr '04

05 Apr '04

Ahoy, I added a hopefully nice feature: Lisp teaches Emacs how to indent macros. I found a way to do it without hacking Emacs's indentation code at all. >From now on when you have a macro like: (defmacro foo (a b &body body) ...) anywhere in your Lisp image, Emacs should know to indent calls as: (foo ((x y)) (bar) (baz) (beer)) i.e. it groks &body. Details and caveats are in the manual (and I put fresh versions in my ~/misc/lisp web directory). Feedback / tweak-suggestions appreciated. -Luke

[slime-devel] [PATCH]: put working directory in header-line
by Sean O'Rourke 05 Apr '04

05 Apr '04

This minor patch compresses the existing header-line information in the REPL, and adds the current working directory (*default-pathname-defaults*). I think it's a nice bit of information to have there when you're dealing with files from multiple directories. Do other people find it useful? /s
