59 "An advanced replacement for `buffer-menu'.
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
78 for display.
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
91 on that buffer.
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
104 nil (don't elide).
106 Some example of valid entries in `ibuffer-formats', with
107 description (also, feel free to try them out, and experiment with your
108 own!):
110 (mark \" \" name)
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
121 right.
123 Thus, if you wanted to use these two formats, add
125 (setq ibuffer-formats '((mark \" \" name)
126 (mark modified read-only
127 (name 16 16 :left) (size 6 -1 :right))))
129 to your ~/.emacs file.
131 Using \\[ibuffer-switch-format], you can rotate the display between
132 the specified formats in the list."

2335 In Ibuffer, you can conveniently perform many operations on the
2336 currently open buffers, in addition to filtering your view to a
2337 particular subset of them, and sorting by various criteria.
2339 Operations on marked buffers:
2341 '\\[ibuffer-do-save]' - Save the marked buffers
2342 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2343 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2344 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2345 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2346 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2347 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
2348 buffers.
2349 '\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
2350 '\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
2351 '\\[ibuffer-do-print]' - Print the marked buffers.
2352 '\\[ibuffer-do-occur]' - List lines in all marked buffers which match
2353 a given regexp (like the function `occur').

2356 '\\[ibuffer-do-shell-command-pipe-replace]' - Replace the contents of the marked
2357 buffers with the output of a shell command.
2358 '\\[ibuffer-do-shell-command-file]' - Run a shell command with the
2359 buffer's file as an argument.
2360 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2361 is a very flexible command. For example, if you want to make all
2362 of the marked buffers read only, try using (toggle-read-only 1) as
2363 the input form.
2364 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2365 is evaluated.
2366 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,
2367 but don't kill the associated buffer.

2383 regardless of whether or not they have an associated file.
2384 '\\[ibuffer-mark-special-buffers]' - Mark all buffers whose name begins and
2385 ends with '*'.
2386 '\\[ibuffer-mark-dissociated-buffers]' - Mark all buffers which have
2387 an associated file, but that file doesn't currently exist.
2388 '\\[ibuffer-mark-read-only-buffers]' - Mark all read-only buffers.
2389 '\\[ibuffer-mark-dired-buffers]' - Mark buffers in `dired' mode.

2402 '\\[ibuffer-filter-by-content]' - Add a filter by buffer content.
2403 '\\[ibuffer-filter-by-filename]' - Add a filter by filename.
2404 '\\[ibuffer-filter-by-size-gt]' - Add a filter by buffer size.

2450 '\\[ibuffer-bury-buffer]' - Bury (not kill!) the buffer on this line.
2452 ** Information on Filtering:
2454 You can filter your ibuffer view via different critera. Each Ibuffer
2455 buffer has its own stack of active filters. For example, suppose you
2456 are working on an Emacs Lisp project. You can create an Ibuffer
2457 buffer displays buffers in just `emacs-lisp' modes via
2458 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2459 is just one entry on the filtering stack.
2461 You can also combine filters. The various filtering commands push a
2462 new filter onto the stack, and the filters combine to show just
2463 buffers which satisfy ALL criteria on the stack. For example, suppose
2464 you only want to see buffers in `emacs-lisp' mode, whose names begin
2465 with \"gnus\". You can accomplish this via:
2466 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2467 \\[ibuffer-filter-by-name] ^gnus RET'.
2469 Additionally, you can OR the top two filters together with
2470 '\\[ibuffer-or-filters]'. To see all buffers in either
2471 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2473 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2475 Filters can also be saved and restored using mnemonic names: see the
2476 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2478 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2479 to disable all filtering currently in effect, use
2480 '\\[ibuffer-filter-disable]'.
2482 ** Filter Groups:
2484 Once one has mastered filters, the next logical step up is \"filter
2485 groups\". A filter group is basically a named group of buffers which
2486 match a filter, which are displayed together in an Ibuffer buffer. To
2487 create a filter group, simply use the regular functions to create a
2488 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2490 A quick example will make things clearer. Suppose that one wants to
2491 group all of one's Emacs Lisp buffers together. To do this, type
2493 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2495 You may, of course, name the group whatever you want; it doesn't have
2496 to be \"emacs lisp buffers\". Filter groups may be composed of any
2497 arbitrary combination of filters.
2499 Just like filters themselves, filter groups act as a stack. Buffers
2500 will not be displayed multiple times if they would be included in
2501 multiple filter groups; instead, the first filter group is used. The
2502 filter groups are displayed in this order of precedence.
2504 You may rearrange filter groups by using the regular
2505 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2506 will be inserted before the group at point."
