"Advanced replacement for `buffer-menu'.
Ibuffer lets you operate on buffers in a Dired-like way,
with the ability to sort, mark by regular expression,
and filter displayed buffers by various criteria."

"A list of ways to display buffer lines.
With Ibuffer, you are not limited to displaying just certain
attributes of a buffer such as size, name, and mode in a particular
order. 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, and shorter names will be padded with spaces), and
the name is also aligned to the left. 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, the appropriate
value for this variable would be
\\='((mark \" \" name)
(mark modified read-only
(name 16 16 :left)
(size 6 -1 :right)))
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-mode-map>
`\\[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-isearch]' - Do incremental search in the marked buffers.
`\\[ibuffer-do-isearch-regexp]' - Isearch for regexp in 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.

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 (read-only-mode 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.

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-save-filters]' - Save the current filters with a name.
`\\[ibuffer-switch-to-saved-filters]' - Switch to previously saved filters.
`\\[ibuffer-add-saved-filters]' - Add saved filters to current filters.
`\\[ibuffer-or-filter]' - Replace the top two filters with their logical OR.
`\\[ibuffer-pop-filter]' - Remove the top filter.
`\\[ibuffer-negate-filter]' - Invert the logical sense of the top filter.
`\\[ibuffer-decompose-filter]' - Break down the topmost filter.

Prefix arg means to toggle whether buffers that match
`ibuffer-maybe-show-predicates' should be displayed.
`\\[ibuffer-switch-format]' - Change the current display format.
`\\[forward-line]' - Move point to the next line.
`\\[previous-line]' - Move point to the previous line.

** Information on Filtering:
You can filter your ibuffer view via different criteria. 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]'.
** Filter Groups:
Once one has mastered filters, the next logical step up is \"filter
groups\". A filter group is basically a named group of buffers which
match a filter, which are displayed together in an Ibuffer buffer. To
create a filter group, simply use the regular functions to create a
filter, and then type `\\[ibuffer-filters-to-filter-group]'.
A quick example will make things clearer. Suppose that one wants to
group all of one's Emacs Lisp buffers together. To do this, type:
\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
\\[ibuffer-filters-to-filter-group] emacs lisp buffers RET
You may, of course, name the group whatever you want; it doesn't have
to be \"emacs lisp buffers\". Filter groups may be composed of any
arbitrary combination of filters.
Just like filters themselves, filter groups act as a stack. Buffers
will not be displayed multiple times if they would be included in
multiple filter groups; instead, the first filter group is used. The
filter groups are displayed in this order of precedence.
You may rearrange filter groups by using the regular
`\\[ibuffer-kill-line]' and `\\[ibuffer-yank]' pair. Yanked groups
will be inserted before the group at point."
