Automatically viewing diffs while composing changes with vc-mode

Then after entering my changelog entry and committing with 'C-c C-c', I always immediately close the *VC-Diff*... more »

|

VM CRASH buffers
|
| |
If anyone out there is a VM user, I could use some help. I've got VM configured and it works pretty well. But when VM is running (and after I close it) there are a bunch of buffers open to e-mail messages in my CRASH box. For every mail I read, there is a buffer named ~/Mail/CRASH.mbox open. The file "CRASH.mbox"... more »

Detecting if a file is binary
|
| |
Is there a way in emacs-lisp code to detect if a file binary, that is it does *not* contain a correct multi-character coding. Or can every possible combination of bytes always be correctly decoded by some character coding? /Nordlöw

How to scroll 2 buffers at once

| |
I thought I remembered being able to scroll 2 buffers in separate windows at the same time... but stepping thru all the hits on `scroll' in a search of the commands (C-h b). I'm not finding one that applies to two windows at once.

Execute In Multiple Shells?

Hi, How can I send the same command to multiple shell buffers at the same time? That is, if I have 5 bash shells running, how can I send "source ./.bash" to all of them at once? Thanks, -T

Is it possible for a macro to expand to nothing?
|
| |
That is, not to a call to a null defun, but truly to nothing: i.e., the ensuing code (as least, when byte compiled) will be identical to what it would have been, had the macro invocation been omitted. I want something like this: (defmacro ifdef (condition &rest forms) "If the compile time CONDITION is non-nil, dump the FORMS to the... more »
