61 Ibuffer allows you to operate on buffers in a manner much like Dired.
62 Operations include sorting, marking by regular expression, and
63 the ability to filter the displayed buffers by various criteria."

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

111 This format just displays the current mark (if any) and the name of
112 the buffer, separated by a space.
113 (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
114 This format displays the current mark (if any), its modification and
115 read-only status, as well as the name of the buffer and its size. In
116 this format, the name is restricted to 16 characters (longer names
117 will be truncated, and shorter names will be padded with spaces), and
118 the name is also aligned to the left. The size of the buffer will
119 be padded with spaces up to a minimum of six characters, but there is
120 no upper limit on its size. The size will also be aligned to the
123 Thus, if you wanted to use these two formats, add

2319 In Ibuffer, you can conveniently perform many operations on the
2320 currently open buffers, in addition to filtering your view to a
2321 particular subset of them, and sorting by various criteria.
2323 Operations on marked buffers:
2325 '\\[ibuffer-do-save]' - Save the marked buffers
2326 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2327 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2328 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2329 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2330 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2331 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked

2335 '\\[ibuffer-do-print]' - Print the marked buffers.

2343 buffer's file as an argument.
2344 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2345 is a very flexible command. For example, if you want to make all
2346 of the marked buffers read only, try using (toggle-read-only 1) as
2348 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2350 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,

2436 ** Information on Filtering:
2438 You can filter your ibuffer view via different critera. Each Ibuffer
2439 buffer has its own stack of active filters. For example, suppose you
2440 are working on an Emacs Lisp project. You can create an Ibuffer
2441 buffer displays buffers in just `emacs-lisp' modes via
2442 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2443 is just one entry on the filtering stack.
2445 You can also combine filters. The various filtering commands push a
2446 new filter onto the stack, and the filters combine to show just
2447 buffers which satisfy ALL criteria on the stack. For example, suppose
2448 you only want to see buffers in `emacs-lisp' mode, whose names begin
2449 with \"gnus\". You can accomplish this via:
2450 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2451 \\[ibuffer-filter-by-name] ^gnus RET'.
2453 Additionally, you can OR the top two filters together with
2454 '\\[ibuffer-or-filters]'. To see all buffers in either
2455 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2457 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2459 Filters can also be saved and restored using mnemonic names: see the
2460 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2462 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2463 to disable all filtering currently in effect, use
2464 '\\[ibuffer-filter-disable]'.
2468 Once one has mastered filters, the next logical step up is \"filter
2469 groups\". A filter group is basically a named group of buffers which
2470 match a filter, which are displayed together in an Ibuffer buffer. To
2471 create a filter group, simply use the regular functions to create a
2472 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2474 A quick example will make things clearer. Suppose that one wants to
2475 group all of one's Emacs Lisp buffers together. To do this, type
2477 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2479 You may, of course, name the group whatever you want; it doesn't have
2480 to be \"emacs lisp buffers\". Filter groups may be composed of any
2481 arbitrary combination of filters.
2483 Just like filters themselves, filter groups act as a stack. Buffers
2484 will not be displayed multiple times if they would be included in
2485 multiple filter groups; instead, the first filter group is used. The
2486 filter groups are displayed in this order of precedence.
2488 You may rearrange filter groups by using the regular
2489 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2490 will be inserted before the group at point."
