You can try to use the `inspect` package newly added to GNU ELPA. Personally, in similar circumstances I tend to do the following: e (setq my-foo <THEVARIABLE>) RET and then I go to my trusty `ielm` buffer to look at `my-foo` in all its glory.

That's what I do, too, but it's kinda cumbersome, isn't it? So I've now made `C-u e' in edebug in Emacs 29 pop up a new buffer and pretty-print the value. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no ^ permalink raw reply [flat|nested] 9+ messages in thread

Not really, because most of the time I don't just want to see the full value but I want to actually use it, passing it to functions, etc... which is a lot more convenient to do in IELM than in Edebug.

I was always using C-x C-e to evaluate last expression, why not include that also with C-u, becase that one automatically knows what to evaluate. While when I press only "e" I get the prompt "Edebug eval: " and then I need to enter name of variable making it more work than C-x C-e -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.

Hm... Yes, `M-0 C-x C-e' maps to NO-TRUNCATE, but I guess we could have `C-u C-x C-e' map to PP. Now fixed in Emacs 29. ^ permalink raw reply [flat|nested] 9+ messages in thread

What about using mouse pointer as a "secondary cursor", if we would like to see some previous value, so we don't have to move cursor around: (defun pointer (x y) (save-excursion (goto-char (window-start)) (forward-line x) (when (> (- (line-end-position) (line-beginning-position)) y) (move-to-column y) (1- (point))))) (defun symbol-value-under-pointer () (interactive) (save-excursion (let ((pointer (mouse-position))) (goto-char (pointer (cddr pointer) (cadr pointer))) (let ((sym (intern-soft (current-word)))) (when sym (message "%S: %S" sym (symbol-value sym))))))) Could that be useful to have on a C-u C-u e? ^ permalink raw reply [flat|nested] 9+ messages in thread

Anyway, I just replied on what you wrote: > That's what I do, too, but it's kinda cumbersome, isn't it? So I've now > made `C-u e' in edebug in Emacs 29 pop up a new buffer and pretty-print > the value. If you just pretty print it in a separate buffer, it is almost as good as in a tooltip, but can be a bit distracting depending on how Emacs chose to split buffer. Didn't have time to build and test your code, my build is like two weeks old or so. >> What about using mouse pointer as a "secondary cursor", if we would >> like to see some previous value, so we don't have to move cursor >> around: > > [...] > >> Could that be useful to have on a C-u C-u e? > > It sounds like a quite specialised use case. Examining the value of a variable while debugging? For me it is a normal thing. I press 'e' and then type the name of a variable, or I sometimes move curser at the end of var/expression and press C-x C-e. Would be nice if edebug instrumented code with help-echo to display values, or even the doc together with the value, similar as in help buffer but in a tooltip. That way we could just move the pointer over symbols and quickly see values/docs, instead of pressing e and typing. ^ permalink raw reply [flat|nested] 9+ messages in thread
