43 "An advanced replacement for `buffer-menu'.
45 Ibuffer allows you to operate on buffers in a manner much like Dired.
46 Operations include sorting, marking by regular expression, and
47 the ability to filter the displayed buffers by various criteria."

54 "A list of ways to display buffer lines.
56 With Ibuffer, you are not limited to displaying just certain
57 attributes of a buffer such as size, name, and mode in a particular
58 order. Through this variable, you can completely customize and
59 control the appearance of an Ibuffer buffer. See also
60 `define-ibuffer-column', which allows you to define your own columns
63 This variable has the form
64 ((COLUMN COLUMN ...) (COLUMN COLUMN ...) ...)
65 Each element in `ibuffer-formats' should be a list containing COLUMN
66 specifiers. A COLUMN can be any of the following:
68 SYMBOL - A symbol naming the column. Predefined columns are:
69 mark modified read-only name size mode process filename
70 When you define your own columns using `define-ibuffer-column', just
71 use their name like the predefined columns here. This entry can
72 also be a function of two arguments, which should return a string.
73 The first argument is the buffer object, and the second is the mark
76 \"STRING\" - A literal string to display.
78 (SYMBOL MIN-SIZE MAX-SIZE &optional ALIGN ELIDE) - SYMBOL is a
79 symbol naming the column, and MIN-SIZE and MAX-SIZE are integers (or
80 functions of no arguments returning an integer) which constrict the
81 size of a column. If MAX-SIZE is -1, there is no upper bound. The
82 default values are 0 and -1, respectively. If MIN-SIZE is negative,
83 use the end of the string. The optional element ALIGN describes the
84 alignment of the column; it can be :left, :center or :right. The
85 optional element ELIDE describes whether or not to elide the column
86 if it is too long; valid values are :elide and nil. The default is
89 Some example of valid entries in `ibuffer-formats', with

95 the buffer, separated by a space.
96 (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
97 This format displays the current mark (if any), its modification and
98 read-only status, as well as the name of the buffer and its size. In
99 this format, the name is restricted to 16 characters (longer names
100 will be truncated, and shorter names will be padded with spaces), and
101 the name is also aligned to the left. The size of the buffer will
102 be padded with spaces up to a minimum of six characters, but there is
103 no upper limit on its size. The size will also be aligned to the
106 Thus, if you wanted to use these two formats, add
108 (setq ibuffer-formats '((mark \" \" name)
109 (mark modified read-only

2283 "A major mode for viewing a list of buffers.
2284 In ibuffer, you can conveniently perform many operations on the
2285 currently open buffers, in addition to filtering your view to a
2286 particular subset of them, and sorting by various criteria.
2288 Operations on marked buffers:
2290 '\\[ibuffer-do-save]' - Save the marked buffers
2291 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2292 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2293 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2294 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2295 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2296 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
2298 '\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
2299 '\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
2300 '\\[ibuffer-do-print]' - Print the marked buffers.
2301 '\\[ibuffer-do-occur]' - List lines in all marked buffers which match

2307 '\\[ibuffer-do-shell-command-file]' - Run a shell command with the
2308 buffer's file as an argument.
2309 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2310 is a very flexible command. For example, if you want to make all
2311 of the marked buffers read only, try using (toggle-read-only 1) as
2313 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2315 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,

2401 ** Information on Filtering:
2403 You can filter your ibuffer view via different critera. Each Ibuffer
2404 buffer has its own stack of active filters. For example, suppose you
2405 are working on an Emacs Lisp project. You can create an Ibuffer
2406 buffer displays buffers in just `emacs-lisp' modes via
2407 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2408 is just one entry on the filtering stack.
2410 You can also combine filters. The various filtering commands push a
2411 new filter onto the stack, and the filters combine to show just
2412 buffers which satisfy ALL criteria on the stack. For example, suppose
2413 you only want to see buffers in `emacs-lisp' mode, whose names begin
2414 with \"gnus\". You can accomplish this via:
2415 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2416 \\[ibuffer-filter-by-name] ^gnus RET'.
2418 Additionally, you can OR the top two filters together with
2419 '\\[ibuffer-or-filters]'. To see all buffers in either
2420 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2422 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2424 Filters can also be saved and restored using mnemonic names: see the
2425 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2427 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2428 to disable all filtering currently in effect, use
2429 '\\[ibuffer-filter-disable]'.
2433 Once one has mastered filters, the next logical step up is \"filter
2434 groups\". A filter group is basically a named group of buffers which
2435 match a filter, which are displayed together in an Ibuffer buffer. To
2436 create a filter group, simply use the regular functions to create a
2437 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2439 A quick example will make things clearer. Suppose that one wants to
2440 group all of one's Emacs Lisp buffers together. To do this, type
2442 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2444 You may, of course, name the group whatever you want; it doesn't have
2445 to be \"emacs lisp buffers\". Filter groups may be composed of any
2446 arbitrary combination of filters.
2448 Just like filters themselves, filter groups act as a stack. Buffers
2449 will not be displayed multiple times if they would be included in
2450 multiple filter groups; instead, the first filter group is used. The
2451 filter groups are displayed in this order of precedence.
2453 You may rearrange filter groups by using the regular
2454 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2455 will be inserted before the group at point."
