Buffers and frames

Buffers and frames

[Gary]

Maybe I'm peculiar, but what I would like to do is kind of "lock" some
buffers to frames (or maybe I mean the opposite, I'm not sure). That is,
I would like to only be offered certain buffers when list-buffers is run
in a certain frame. Possible?

For example, I want to have gnus and only gnus in one frame, my php
editing buffers (and only...) in another frame, and so on.

I'm wondering if I could somehow use ido to do this (ido-ignore-buffers)
but it looks like that might be rather long winded. Ideally I would
simply like buffers opened in one frame to only be visible in that one
frame (perhaps with a way of "forcing" all buffers to be visible on a
case by case basis).

Sounds like the frame-parameter `buffer-predicate' should do pretty much
what you want, according to the Elisp manual:

`buffer-predicate'
     The buffer-predicate function for this frame.  The function
     `other-buffer' uses this predicate (from the selected frame) to
     decide which buffers it should consider, if the predicate is not
     `nil'.  It calls the predicate with one argument, a buffer, once
     for each buffer; if the predicate returns a non-`nil' value, it
     considers that buffer.

But, as the above says, it only applies to `other-buffer'.  But I think
this is a misfeature which would deserve to be fixed.  So please try it
out and when it doesn't DTRT (i.e. when a command ignores this parameter
whereas you'd want it to obey it), please report it with M-x
report-emacs-bug.

I won't even attempt to approach this from an elisp perspective but
have you considered just launching multiple emacs instances, perhaps
with different default frame names, to house the different purposes
you're using it for? It's almost like you're using emacs as an OS at
this point and launching your PHP IDE and your Mail Reader, etc.

Just a thought. Obviously, it's not ideal.

I don't really want to do that. I like everything in one place (even if
that place is spread across a few frames), so I can just use the
keyboard in one window. My colleagues think I'm mad, btw.

Well, isn't it? <g>

Look up dedicated windows in the doc - e.g. `(elisp) Dedicated Windows'.

That's something different from locking a frame/window to a particular buffer.

See option `Buffer-menu-use-frame-buffer-list'.  If that doesn't give you what
you want, you should be able to write a little Lisp code based on the code in
buff-menu.el.

That's something different from the first two things you mentioned.  I don't
know a simple answer for that, but at least take a look at option
`display-buffer-reuse-frames'.  It doesn't _prevent_ display of a buffer in more
than one frame (e.g. `C-x 5 2'), but it might be sufficient for your use case.

as Drew suggested, Dedicated Windows is probably the place to start looking;
this snippet was posted on the list some time ago:
