With Ibuffer, you are not limited to displaying just certain
|
|
attributes of a buffer such as size, name, and mode in a particular
|
|
fashion. Through this variable, you can completely customize and
|
|
control the appearance of an Ibuffer buffer. See also
|
|
`define-ibuffer-column', which allows you to define your own columns
|
|
for display.
|
|
|
|
This variable has the form
|
|
((COLUMN COLUMN ...) (COLUMN COLUMN ...) ...)
|
|
Each element in `ibuffer-formats' should be a list containing COLUMN
|
|
specifiers. A COLUMN can be any of the following:
|
|
|
|
SYMBOL - A symbol naming the column. Predefined columns are:
|
|
mark modified read-only name size mode process filename
|
|
When you define your own columns using `define-ibuffer-column', just
|
|
use their name like the predefined columns here. This entry can
|
|
also be a function of two arguments, which should return a string.
|
|
The first argument is the buffer object, and the second is the mark
|
|
on that buffer.
|
|
or
|
|
\"STRING\" - A literal string to display.
|
|
or
|
|
(SYMBOL MIN-SIZE MAX-SIZE &optional ALIGN ELIDE) - SYMBOL is a
|
|
symbol naming the column, and MIN-SIZE and MAX-SIZE are integers (or
|
|
functions of no arguments returning an integer) which constrict the
|
|
size of a column. If MAX-SIZE is -1, there is no upper bound. The
|
|
default values are 0 and -1, respectively. If MIN-SIZE is negative,
|
|
use the end of the string. The optional element ALIGN describes the
|
|
alignment of the column; it can be :left, :center or :right. The
|
|
optional element ELIDE describes whether or not to elide the column
|
|
if it is too long; valid values are :elide and nil. The default is
|
|
nil (don't elide).
|
|
|
|
Some example of valid entries in `ibuffer-formats', with
|
|
description (also, feel free to try them out, and experiment with your
|
|
own!):
|
|
|
|
(mark \" \" name)
|
|
This format just displays the current mark (if any) and the name of
|
|
the buffer, separated by a space.
|
|
(mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
|
|
This format displays the current mark (if any), its modification and
|
|
read-only status, as well as the name of the buffer and its size. In
|
|
this format, the name is restricted to 16 characters (longer names
|
|
will be truncated, nad shorter names will be padded with spaces), and
|
|
the name is also aligned to the right. The size of the buffer will
|
|
be padded with spaces up to a minimum of six characters, but there is
|
|
no upper limit on its size. The size will also be aligned to the
|
|
right.
|
|
|
|
Thus, if you wanted to use these two formats, add
|
|
|
|
(setq ibuffer-formats '((mark \" \" name)
|
|
(mark modified read-only
|
|
(name 16 16 :left) (size 6 -1 :right))))
|
|
|
|
to your ~/.emacs file.
|
|
|
|
Using \\[ibuffer-switch-format], you can rotate the display between
|
|
the specified formats in the list."

"A major mode for viewing a list of buffers.
|
|
In ibuffer, you can conveniently perform many operations on the
|
|
currently open buffers, in addition to filtering your view to a
|
|
particular subset of them, and sorting by various criteria.
|
|
|
|
Operations on marked buffers:
|
|
|
|
'\\[ibuffer-do-save]' - Save the marked buffers
|
|
'\\[ibuffer-do-view]' - View the marked buffers in this frame.
|
|
'\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
|
|
'\\[ibuffer-do-revert]' - Revert the marked buffers.
|
|
'\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
|
|
'\\[ibuffer-do-delete]' - Kill the marked buffers.
|
|
'\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
|
|
buffers.
|
|
'\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
|
|
'\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
|
|
'\\[ibuffer-do-print]' - Print the marked buffers.
|
|
'\\[ibuffer-do-occur]' - List lines in all marked buffers which match
|
|
a given regexp (like the function `occur').
|
|
'\\[ibuffer-do-shell-command-pipe]' - Pipe the contents of the marked
|
|
buffers to a shell command.
|
|
'\\[ibuffer-do-shell-command-pipe-replace]' - Replace the contents of the marked
|
|
buffers with the output of a shell command.
|
|
'\\[ibuffer-do-shell-command-file]' - Run a shell command with the
|
|
buffer's file as an argument.
|
|
'\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
|
|
is a very flexible command. For example, if you want to make all
|
|
of the marked buffers read only, try using (toggle-read-only 1) as
|
|
the input form.
|
|
'\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
|
|
is evaluated.
|
|
'\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,
|
|
but don't kill the associated buffer.
|
|
'\\[ibuffer-do-kill-on-deletion-marks]' - Kill all buffers marked for deletion.
|
|
|
|
Marking commands:
|
|
|
|
'\\[ibuffer-mark-forward]' - Mark the buffer at point.
|
|
'\\[ibuffer-toggle-marks]' - Unmark all currently marked buffers, and mark
|
|
all unmarked buffers.
|
|
'\\[ibuffer-unmark-forward]' - Unmark the buffer at point.
|
|
'\\[ibuffer-unmark-backward]' - Unmark the buffer at point, and move to the
|
|
previous line.
|
|
'\\[ibuffer-unmark-all]' - Unmark all marked buffers.
|
|
'\\[ibuffer-mark-by-mode]' - Mark buffers by major mode.
|
|
'\\[ibuffer-mark-unsaved-buffers]' - Mark all \"unsaved\" buffers.
|
|
This means that the buffer is modified, and has an associated file.
|
|
'\\[ibuffer-mark-modified-buffers]' - Mark all modified buffers,
|
|
regardless of whether or not they have an associated file.
|
|
'\\[ibuffer-mark-special-buffers]' - Mark all buffers whose name begins and
|
|
ends with '*'.
|
|
'\\[ibuffer-mark-dissociated-buffers]' - Mark all buffers which have
|
|
an associated file, but that file doesn't currently exist.
|
|
'\\[ibuffer-mark-read-only-buffers]' - Mark all read-only buffers.
|
|
'\\[ibuffer-mark-dired-buffers]' - Mark buffers in `dired' mode.
|
|
'\\[ibuffer-mark-help-buffers]' - Mark buffers in `help-mode', `apropos-mode', etc.
|
|
'\\[ibuffer-mark-old-buffers]' - Mark buffers older than `ibuffer-old-time'.
|
|
'\\[ibuffer-mark-for-delete]' - Mark the buffer at point for deletion.
|
|
'\\[ibuffer-mark-by-name-regexp]' - Mark buffers by their name, using a regexp.

|
|
|
|
'\\[ibuffer-filter-by-mode]' - Add a filter by major mode.
|
|
'\\[ibuffer-filter-by-name]' - Add a filter by buffer name.
|
|
'\\[ibuffer-filter-by-content]' - Add a filter by buffer content.
|
|
'\\[ibuffer-filter-by-filename]' - Add a filter by filename.
|
|
'\\[ibuffer-filter-by-size-gt]' - Add a filter by buffer size.
|
|
'\\[ibuffer-filter-by-size-lt]' - Add a filter by buffer size.

|
|
Information on Filtering:
|
|
|
|
You can filter your ibuffer view via different critera. Each Ibuffer
|
|
buffer has its own stack of active filters. For example, suppose you
|
|
are working on an Emacs Lisp project. You can create an Ibuffer
|
|
buffer displays buffers in just `emacs-lisp' modes via
|
|
'\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
|
|
is just one entry on the filtering stack.
|
|
|
|
You can also combine filters. The various filtering commands push a
|
|
new filter onto the stack, and the filters combine to show just
|
|
buffers which satisfy ALL criteria on the stack. For example, suppose
|
|
you only want to see buffers in `emacs-lisp' mode, whose names begin
|
|
with \"gnus\". You can accomplish this via:
|
|
'\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
|
|
\\[ibuffer-filter-by-name] ^gnus RET'.
|
|
|
|
Additionally, you can OR the top two filters together with
|
|
'\\[ibuffer-or-filters]'. To see all buffers in either
|
|
`emacs-lisp-mode' or `lisp-interaction-mode', type:
|
|
|
|
'\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
|
|
|
|
Filters can also be saved and restored using mnemonic names: see the
|
|
functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
|
|
|
|
To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
|
|
to disable all filtering currently in effect, use
|
|
'\\[ibuffer-filter-disable]'."
