[clim-desktop-devel] Mouse-sensitive symbols in buffers!
by Troels Henriksen 26 Mar '06

26 Mar '06

Simple, but cool: (in-package :climacs-lisp-syntax) (define-presentation-to-command-translator edit-definition (symbol com-edit-definition lisp-table :gesture :select :tester ((object presentation) (declare (ignore object)) (not (eq (presentation-type presentation) 'unknown-symbol))) :documentation "Edit definition") (object) (list object)) (define-command (com-inspect-symbol :name t :command-table lisp-table) ((symbol 'symbol :prompt "Edit symbol")) (clouseau:inspector symbol :new-process t)) (define-presentation-to-command-translator inspect-symbol (symbol com-inspect-symbol lisp-table :gesture :describe :tester ((object presentation) (declare (ignore object)) (not (eq (presentation-type presentation) 'unknown-symbol))) :documentation "Inspect") (object) (list object)) This will make various Lisp symbols mouse-sensitive when editing Lisp code. Should this be in Swine? I think it's cool, but I'm not sure whether it is genuinely useful or just a gimmick. -- \ Troels "Athas" Henriksen /\ - Insert witty signature

[clim-desktop-devel] Patch: Fix for error-causing Swine bug
by Troels Henriksen 14 Mar '06

If the first symbol of a list is a keyword symbol, Swine will signal an error when it tries to look up its arglist. The attached patch fixes this issue.
