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."

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

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

2298 In ibuffer, you can conveniently perform many operations on the
2299 currently open buffers, in addition to filtering your view to a
2300 particular subset of them, and sorting by various criteria.
2302 Operations on marked buffers:
2304 '\\[ibuffer-do-save]' - Save the marked buffers
2305 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2306 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2307 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2308 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2309 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2310 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked

2314 '\\[ibuffer-do-print]' - Print the marked buffers.
2315 '\\[ibuffer-do-occur]' - List lines in all marked buffers which match

2322 buffer's file as an argument.
2323 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2324 is a very flexible command. For example, if you want to make all
2325 of the marked buffers read only, try using (toggle-read-only 1) as
2327 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2329 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,

2415 ** Information on Filtering:
2417 You can filter your ibuffer view via different critera. Each Ibuffer
2418 buffer has its own stack of active filters. For example, suppose you
2419 are working on an Emacs Lisp project. You can create an Ibuffer
2420 buffer displays buffers in just `emacs-lisp' modes via
2421 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2422 is just one entry on the filtering stack.
2424 You can also combine filters. The various filtering commands push a
2425 new filter onto the stack, and the filters combine to show just
2426 buffers which satisfy ALL criteria on the stack. For example, suppose
2427 you only want to see buffers in `emacs-lisp' mode, whose names begin
2428 with \"gnus\". You can accomplish this via:
2429 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2430 \\[ibuffer-filter-by-name] ^gnus RET'.
2432 Additionally, you can OR the top two filters together with
2433 '\\[ibuffer-or-filters]'. To see all buffers in either
2434 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2436 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2438 Filters can also be saved and restored using mnemonic names: see the
2439 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2441 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2442 to disable all filtering currently in effect, use
2443 '\\[ibuffer-filter-disable]'.
2447 Once one has mastered filters, the next logical step up is \"filter
2448 groups\". A filter group is basically a named group of buffers which
2449 match a filter, which are displayed together in an Ibuffer buffer. To
2450 create a filter group, simply use the regular functions to create a
2451 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2453 A quick example will make things clearer. Suppose that one wants to
2454 group all of one's Emacs Lisp buffers together. To do this, type
2456 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2458 You may, of course, name the group whatever you want; it doesn't have
2459 to be \"emacs lisp buffers\". Filter groups may be composed of any
2460 arbitrary combination of filters.
2462 Just like filters themselves, filter groups act as a stack. Buffers
2463 will not be displayed multiple times if they would be included in
2464 multiple filter groups; instead, the first filter group is used. The
2465 filter groups are displayed in this order of precedence.
2467 You may rearrange filter groups by using the regular
2468 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2469 will be inserted before the group at point."
