Saving buffers before start of compilatione

Saving buffers before start of compilatione

[Markus Gessner]

Hello,

is there a way to exclude certain buffers as candidates to be saved
before compiling when using M-x compile?

For example, I am asked, whether the .newsrc-dribble file, which is
generated by Gnus, should be saved before the compile is launched. As
this and potentially other files are not related to the compilation, I
wonder, whether there is a variable, which holds patterns of filenames
not to be considered for saving before compiling.

I understand, that setting the variable compilation-ask-about-save to
nil has the effect of all changed buffers being saved without asking
first, which would not be the same.

If there is no such exclusion mechanism, the only solution seems to be
to start a separate instance of Emacs for editing and compiling in order
to avoid clashes with unrelated buffers.

Thanks for hints!
Markus

Take a look at `compilation-save-buffers-predicate'.

Exist this in Emacs 23? I can't find it.

Me neither, this seems to be new in Emacs 24.  Maybe it's time for me to
try the trunk, since this feature seems rather useful.

Sven, 
     always annoyed when Emacs asks if it should save ~/.newsrc-dribble.

The same here when I compile or validate xml files and I have unsaved 
buffers.
