[slime-devel] Improvement request to M-.
I noticed that it doesn't handle class names. Would it be possible to have it find the definition for a class if it doesn't find another meaning of the word? It also seems to skip over defparameters. Chris Capel

This requires support from your Lisp implementation. SBCL doesn't have it. You could switch to another Lisp, implement it yourself, or you could try to port the CMUCL code. See: http://article.gmane.org/gmane.lisp.cmucl.devel/5170 http://article.gmane.org/gmane.lisp.cmucl.devel/5358 Helmut.

That's boggles me, as the inspector is able to find classes from their name. I suppose, though, that it can't find the source forms, so that really doesn't mean much of anything. Hmm. I'm scared of compilers, but -- maybe -- with your patches as an example I could rouse up the courage to look at SBCL. Chris Capel

Interestingly enough--and this isn't a condemnation of SLIME in any way--Visual Studio.NET has full capabilities to look up the source location of any variable or definition in the current project. This seems to be implemented completely in the editor, which means that it has to be able to parse C#. Funny. In the vein of copying from VS.NET, I think a neat thing that might be relatively easy to implement is to highlight unmatched parentheses in a form, using as a context the area between the top-level text closest before the point ("(defun" or "(defmacro") and the top-level text after the point. This way it's easy to tell when you need more parentheses somewhere. Or maybe it could be even closer to where the actual parenthesis is needed, by comparing the ideal indentation (as per lisp-indent-line) to the current indentation of the lines. I suppose this would be a rather ambitious project, and of dubious value. But definitely neat. Chris Capel

Parsing the source code with something other than the compiler doesn't work so well with Lisp, or for that matter, any language that has extensible syntax. If a macro expands to a defun, then parsing the source isn't enough. You also have to expand the macro. There are also issues with packages and reader-macros. If you are satisfied with the simple cases, i.e., if the source code actually looks like "(def.* foo", then you can use TAGS files.

Emacs already shows text around the opening paren when you type ')'. So it't not that hard to know when the expression has enough ))). Some people also add 'check-paren to their local-write-file-hooks. Helmut.
