34 ;; This minor mode allows programmers to step through Emacs Lisp
|
|
35 ;; source code while executing functions. You can also set
|
|
36 ;; breakpoints, trace (stopping at each expression), evaluate
|
|
37 ;; expressions as if outside Edebug, reevaluate and display a list of
|
|
38 ;; expressions, trap errors normally caught by debug, and display a
|
|
39 ;; debug style backtrace.
|
|

|
41 ;;; Installation
|
72
|
42 ;; =============
|
|
43
|
|
44 ;; Put edebug.el in some directory in your load-path and
|
|
45 ;; byte-compile it. Also read the beginning of edebug-epoch.el,
|
|
46 ;; cl-specs.el, and edebug-cl-read.el if they apply to you.
|
|
47
|
|
48 ;; Unless you are using Emacs 19 which is already set up to use Edebug,
|
|
49 ;; put the following forms in your .emacs file.
|
|
50 ;; (define-key emacs-lisp-mode-map "\C-xx" 'edebug-eval-top-level-form)
|
|
51 ;; (autoload 'edebug-eval-top-level-form "edebug")
|
|
52
|
|
53 ;; If you wish to change the default edebug global command prefix, change:
|
|
54 ;; (setq edebug-global-prefix "\C-xX")
|
|
55
|
|
56 ;; Other options, are described in the manual.
|
|
57
|
|
58 ;; In previous versions of Edebug, users were directed to set
|
|
59 ;; `debugger' to `edebug-debug'. This is no longer necessary
|
|
60 ;; since Edebug automatically sets it whenever Edebug is active.
|
|
61
|
100
|
62 ;;; Minimal Instructions
|
72
|
63 ;; =====================
|
|
64
|
|
65 ;; First evaluate a defun with C-xx, then run the function. Step
|
|
66 ;; through the code with SPC, mark breakpoints with b, go until a
|
|
67 ;; breakpoint is reached with g, and quit execution with q. Use the
|
|
68 ;; "?" command in edebug to describe other commands. See edebug.tex
|
|
69 ;; or the Emacs 19 Lisp Reference Manual for more instructions.
|
|
70
|
|
71 ;; Send me your enhancements, ideas, bugs, or fixes.
|
|
72 ;; For bugs, you can call edebug-submit-bug-report if you have reporter.el.
|
|
73 ;; There is an edebug mailing list if you want to keep up
|
|
74 ;; with the latest developments. Requests to: edebug-request@cs.uiuc.edu
