Change log of Beframe (beframe.el)
Isolate Emacs buffers per frame
This document contains the release notes for each tagged commit on the project's main git repository: https://git.sr.ht/~protesilaos/beframe.
The newest release is at the top. For further details, please consult the manual: https://protesilaos.com/emacs/beframe.
1.0.0 on 2023-11-17
beframe
is in a stable state. This release formalises a set of
stability enhancements and quality-of-life improvements.
The menu bar helps you discover Beframe commands
A submenu with Beframe commands is available to users of
menu-bar-mode
. It is available at Buffers > BEFRAME buffers
. Check
the original announcement, which includes screenshots:
https://protesilaos.com/codelog/2023-10-08-emacs-beframe-menu/.
[ As an aside, never tell a new user to add (menu-bar-mode -1)
to
their Emacs init file. It is not helpful. ]
The sample integration with consult
can flip between recent buffers
In the manual of beframe
there is a section about augmenting the
consult-buffer
command with a new source of beframed buffers
(buffers specific to the current frame). Edgar Vincent made a change
that sorts buffers by last viewed, meaning that the previous buffer is
at the top of the list. The change is within the ~15 line limit and
thus Edgar does not need to assign copyright to the Free Software
Foundation. Discussed on the mailing list:
https://lists.sr.ht/~protesilaos/general-issues/%3C878r97fxmc.fsf%40protesilaos.com%3E.
Refer to the manual for the code to integrate beframe
with consult
:
https://protesilaos.com/emacs/beframe#h:1c2d3d64-aa7b-4585-a418-ccedbb548b38.
NOTE that you do not need consult
to use beframe
: (i) the
beframe-mode
makes the regular switch-to-buffer
work in a beframed
way and/or (ii) use the beframe-buffer-menu
to get a list of the
beframed buffers (call the latter command with a prefix key (C-u
by
default) to select a frame whose buffers you want to list).
The beframe-rename-function
can take a nil
value
This was always the intent, though the code did not honour it. Thanks to Karthik Chikmagalur for reporting the bug on the mailing list: https://lists.sr.ht/~protesilaos/general-issues/%3C87a5w8yi1n.fsf%40gmail.com%3E.
General refinements
- Commands that prompt for a frame (e.g.
beframe-assume-frame-buffers
) no longer try to perform their work if a single Emacs frame is available. Instead, they return auser-error
. - The buffer that was current when a new frame was created is no
longer part of the new frame's buffer list. This means that the new
frame starts clean, including only the buffer specified in the user
option
beframe-global-buffers
. - The code that renames a new frame based is better at inferring the
correct name. It now finds the
project.el
name, if available. The manual explains how to use Beframe with projects: https://protesilaos.com/emacs/beframe#h:5b751614-8749-4aa8-aaed-f181beaddc57 (to me, this is a killer feature). - Simplified how frames are set up. This guarantees that our functions are called in the desired order.
0.3.0 on 2023-05-21
Use more descriptive names for assume/unassume commands
Beframe limits the buffer list to buffers that are visited in the current frame. I provide commands to assume (add) or unassume (remove) buffers from other frames, making for a powerful and flexible workflow:
- In bulk
- Assume/unassume the (i) entire buffer list of a frame, or the (ii) consolidated buffer list of all frames.
- Selectively
- Use minibuffer completion to compile a list of buffers to assume/unassume (iii) from the given frame, or (iv) buffers from the consolidated buffer list.
The commands that operate selectively are renamed to better describe what they do. We thus have:
Deprecated name | New name |
---|---|
beframe-assume-buffers | beframe-assume-frame-buffers-selectively |
beframe-assume-buffers-all-frames | beframe-assume-buffers-selectively-all-frames |
beframe-unassume-buffers | beframe-unassume-current-frame-buffers-selectively |
To avoid potential confusion, the following command aliases are discontinued:
beframe-add-buffers
beframe-remove-buffers
beframe-add-frame-buffers
beframe-remove-frame-buffers
Provide the beframe-prefix-map
This is a keymap that binds the Beframe commands to recommended keys. As with all Emacs key bindings, those are configurable.
I call it a "prefix" keymap because it is not bound anywhere and cannot be used by default. The user must explicitly bind it to a key, which will be treated as a prefix key. For example:
(define-key global-map (kbd "C-c b") beframe-prefix-map)
With the above code, C-c b
becomes the prefix key that invokes
Beframe commands. Type C-c b C-h
to show the available key
bindings (by default C-h
as a suffix to an incomplete key sequence
produces a Help buffer that links to all the available bindings).
The beframe-prefix-map
and beframe-mode
are used independent of
each other.
Miscellaneous
- Simplify how
beframe-rename-function
is added by thebeframe-mode
. - Refine the application of
beframe-create-frame-scratch-buffer
by thebeframe-mode
. - Tweak the
beframe-buffer-sort-visibility
function to be consistent with the style ofbeframe.el
. - Rewrite parts of the manual to reference the aforementioned.
0.2.0 on 2023-03-27
There were no release notes for the initial version of Beframe. Watch the video demo I produced on 2023-02-28 to get an overview of what this package is all about: https://protesilaos.com/codelog/2023-02-28-emacs-beframe-demo/.
In short: beframe your buffers, not your outlook. Oops that is for the philosophy blog! 🙃
A beframed buffer menu
The command beframe-buffer-menu
produces a dedicated buffer with a
list of buffers for the current frame. This is the counterpart of
beframe-switch-buffer
. When called with a prefix argument (C-u
with default key bindings), it prompts for a frame whose buffers it
will display.
Frame-specific scratch buffer
The user option beframe-create-frame-scratch-buffer
allows
beframe-mode
to create a frame-specific scratch buffer that runs the
initial-major-mode
. This is done upon the creation of a new frame
and the scratch buffer is named after the frame it belongs to. For
example, if the frame is called modus-themes
, the corresponding
scratch buffer is *scratch for modus-themes*
. Set this user option
to nil
to disable the creation of such scratch buffers.
The user option beframe-kill-frame-scratch-buffer
is the counterpart
of beframe-create-frame-scratch-buffer
. It kills the frame-specific
scratch buffer after the frame is deleted. Set this user option to
nil
to disable the killing of such buffers.
Assuming and unassuming buffers
Beframe makes it possible to add or remove buffers from the list of buffers associated with the current frame. This provides for a flexible workflow where buffers can be initially beframed yet consolidated into new lists on demand.
Assuming buffers
To assume buffers is to include them in the buffer list associated with the current frame.
- The command
beframe-assume-frame-buffers
(aliasbeframe-add-frame-buffers
) prompts for a frame and then copies its buffer list into the current frame. - The command
beframe-assume-buffers
(aliasbeframe-add-buffers
) adds buffers from a given frame to the current frame. In interactive use, the command first prompts for a frame and then asks about the list of buffers therein. The to-be-assumed buffer list is compiled withcompleting-read-multiple
. This means that the user can select multiple buffers, each separated by thecrm-separator
(typically a comma). - The command
beframe-assume-buffers-all-frames
prompts with minibuffer completion for a list of buffers to assume. The interface is the same as that ofbeframe-assume-buffers
except that there is no prompt for a frame: buffers belong to the consolidated buffer list (all frames). - The command
beframe-assume-all-buffers-no-prompts
unconditionally assumes the consolidated buffer list.
Unassuming buffers
To unassume buffers is to omit them from the buffer list associated with the current frame.
- The command
beframe-unassume-frame-buffers
(aliasbeframe-remove-frame-buffers
) prompts for a frame and then removes its buffer list from the current frame. - The command
beframe-unassume-buffers
(aliasbeframe-remove-buffers
) removes buffers from the current frame. In interactive use, the to-be-unassumed buffer list is compiled withcompleting-read-multiple
. This means that the user can select multiple buffers, each separated by thecrm-separator
(typically a comma). - The command
beframe-unassume-all-buffers-no-prompts
unconditionally unassumes the consolidated buffer list, but preserves the list stored in the user optionbeframe-global-buffers
.
Sort beframed buffers from Lisp

commit dfa4678c208e1e5c41413f2d39416f84c21f28ff Author: Tony Zorman <soliditsallgood@mailbox.org> Date: Sat Mar 4 11:48:17 2023 +0100
Add the ability to sort the buffer list
Some completion libraries, like consult, give the user the option to sort the list of buffers according to some strategy. For example, sorting by visibility—in the sense that one is first shown hidden buffers, then visible ones, and only then the current buffer—may be preferrable when deciding to switch buffers via consult-buffer.
Since beframe.el can be used as a consult source (see the manual), endowing beframe–buffer-list with an arbitrary sort function greatly improves the synergy between the two libraries.
