Problem setting breakpoint with JDEbug
Hi,
I am new to XEmacs AND to JDE so be indulgent if I am making ridiculous
things.
I have a problem setting a breakpoint with JDEbug. I started the debugger,
launched a process and then tried to set a breakpoint. But nothing happens
except an Error Warning: Symbol`s function definition is void:
line-beginning-position.
Can anyone help me with this? I used the JDE-Help-Submit problem report
function and posted the result below.
Thanks,
Ralf

It may not do exactly the same thing as the code below, but it's sure a heck of a lot simpler. Inger, Matthew wrote: Put this in your .emacs file. It will cycle through the buffers as you hit Control Tab. You may notice, rather than traverse forward in the buffer list when i get the next buffer, I traverse backwords. The reason is that when you are on buffer X and move to buffer Y, it puts buffer X next in the buffer list after Y, so what happens is that you would just swap between the two: ie: (buffer-list) returns (X Y Z A B C) switch to Y while on X (buffer-list) reutrns (Y X Z A B C) See the problem, the next switch will go to X. If we go backwards: (buffer-list) returns (X Y Z A B C) switch to C while on X (buffer-list) reutrns (C X Y Z A B) So, the next call would go to buffer B, then A, and so forth, eliminating the problem. You can change this code to avoid other buffers other than the Minibuf ones (say *scratch*) by adding or closes to the if in the get-next-buffer function. (if (or (string-match ... ) (string-match ... ) (string-match ... )) (get-next-buffer cbuf) cbuf) Here's the code: (defun get-next-buffer(cbuf) (let* ((bufs (buffer-list)) (bufslen (length bufs)) (pos (position cbuf bufs))) (if (eq pos 0) (setq pos (- bufslen 1)) (setq pos (- pos 1))) (setq cbuf (nth pos bufs)) (if (string-match .*Minibuf.* (buffer-name cbuf)) (get-next-buffer cbuf) cbuf)) ) (defun next-buffer() Switch to the next buffer in the list (interactive) (let* ((cbuf (current-buffer))) (setq cbuf (get-next-buffer cbuf)) (switch-to-buffer cbuf) ) ) (global-set-key [C-tab] 'next-buffer) -Original Message- From: Chris [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 31, 2002 1:09 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: (emacs newbie) Modifying JDE Hello all, (Sorry if this is the wrong place to send this) I'm at a new job where we absolutely have no budget for software, and have to try and use free everything. For a Java IDE, we first tried NetBeans, which has many problems, and since I've looked at Forte, Eclipse, and JBuilder Personal Edition, none of which I love. I've been messing around with Unix here and there for years, and so in the back of my mind I've long thought that customizing emacs is naturally the way to go. Rather than live with a 100 Meg + IDE that doesn't do what you want, why not take emacs and *build* what you want? I've used emacs for the last 3 days on a Java project (in plain ol' Java mode), and while there are some things I like, in general the experience has been akin to commuting every day in an old car with no power steering and blown shocks. There's nothing wrong with it, but at the end of the week you're just ragged out. Now, I also know not to blame emacs for this -- it would seem that there are no bad emacs experiences -- just bad modes! Or rather, modes that aren't quite to one's liking. If I'm not mistaken there's likely to be nothing I want to do in emacs that can't be customized. Trouble is I don't know how. In particular, there are a number of things I'd like to be able to do that I can do in TextPad, my shareware editor of choice. Here are things I really miss . . . - Ctrl-Tab to move among open buffers, just like Alt-Tab moves across applications. Ctrl-X B Enter is clunkier, and not quite the same. - Shift-Arrow (or Page Up/Down or other navigation keys I'm overlooking -- ah yes, Home/End) to select, along with Ctrl-Arrow which moves across words, and Del to delete selected text. Ctrl-space, Alt-arrow, Ctrl-W gets you there but too clunky (see no power steering above). - Tab indents a selected region, Shift-Tab unindents. Very handy. - A window that lists open buffers, and lets you click on the one you wish to edit - Less heavy-handedness in specifying tabbing. In particular, I don't ever want to hit Tab *and have nothing happen*. (grrr.) - Ctrl-/ comments a region,
Re: Problem setting breakpoint with JDEbug
Very odd. This should work. To double check, perhaps you can execute these lines: (if (not (fboundp 'line-beginning-position)) (defsubst jde-line-beginning-position (optional N) (save-excursion (beginning-of-line N) (point))) (defalias 'jde-line-beginning-position 'line-beginning-position)) (if (not (fboundp 'line-end-position)) (defsubst jde-line-end-position (optional N) (save-excursion (end-of-line N) (point))) (defalias 'jde-line-end-position 'line-end-position)) Execute them by marking them as a region (using ctrl-space at the beginning and then moving to the end of the region) and then doing M-x eval-region. Does it still happen after you do that? These lines are from jde-db.el, and should insure that line-beginning-position is defined no matter what your system is. Perhaps you do not have these lines, or for some reason they are not executing. To be safe, you really should have a .emacs file. See the JDE manual on how to configure it to use JDE. It may help in this instance, although right now I can't think of a reason why.
