79 "A list of ways to display buffer lines.
81 With Ibuffer, you are not limited to displaying just certain
82 attributes of a buffer such as size, name, and mode in a particular
83 order. Through this variable, you can completely customize and
84 control the appearance of an Ibuffer buffer. See also
85 `define-ibuffer-column', which allows you to define your own columns
86 for display.
88 This variable has the form
89 ((COLUMN COLUMN ...) (COLUMN COLUMN ...) ...)
90 Each element in `ibuffer-formats' should be a list containing COLUMN
91 specifiers. A COLUMN can be any of the following:
93 SYMBOL - A symbol naming the column. Predefined columns are:
94 mark modified read-only name size mode process filename
95 When you define your own columns using `define-ibuffer-column', just
96 use their name like the predefined columns here. This entry can
97 also be a function of two arguments, which should return a string.
98 The first argument is the buffer object, and the second is the mark
99 on that buffer.
101 \"STRING\" - A literal string to display.
103 (SYMBOL MIN-SIZE MAX-SIZE &optional ALIGN ELIDE) - SYMBOL is a
104 symbol naming the column, and MIN-SIZE and MAX-SIZE are integers (or
105 functions of no arguments returning an integer) which constrict the
106 size of a column. If MAX-SIZE is -1, there is no upper bound. The
107 default values are 0 and -1, respectively. If MIN-SIZE is negative,
108 use the end of the string. The optional element ALIGN describes the
109 alignment of the column; it can be :left, :center or :right. The
110 optional element ELIDE describes whether or not to elide the column
111 if it is too long; valid values are :elide and nil. The default is
112 nil (don't elide).
114 Some example of valid entries in `ibuffer-formats', with
115 description (also, feel free to try them out, and experiment with your
116 own!):
118 (mark \" \" name)
119 This format just displays the current mark (if any) and the name of
120 the buffer, separated by a space.
121 (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
122 This format displays the current mark (if any), its modification and
123 read-only status, as well as the name of the buffer and its size. In
124 this format, the name is restricted to 16 characters (longer names
125 will be truncated, and shorter names will be padded with spaces), and
126 the name is also aligned to the left. The size of the buffer will
127 be padded with spaces up to a minimum of six characters, but there is
128 no upper limit on its size. The size will also be aligned to the
129 right.
131 Thus, if you wanted to use these two formats, add
133 (setq ibuffer-formats '((mark \" \" name)
134 (mark modified read-only
135 (name 16 16 :left) (size 6 -1 :right))))
137 to your ~/.emacs file.
139 Using \\[ibuffer-switch-format], you can rotate the display between
140 the specified formats in the list."

2363 In Ibuffer, you can conveniently perform many operations on the
2364 currently open buffers, in addition to filtering your view to a
2365 particular subset of them, and sorting by various criteria.
2367 Operations on marked buffers:
2369 '\\[ibuffer-do-save]' - Save the marked buffers
2370 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2371 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2372 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2373 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2374 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2375 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
2376 buffers.
2377 '\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
2378 '\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
2379 '\\[ibuffer-do-print]' - Print the marked buffers.
2380 '\\[ibuffer-do-occur]' - List lines in all marked buffers which match
2381 a given regexp (like the function `occur').
2382 '\\[ibuffer-do-shell-command-pipe]' - Pipe the contents of the marked
2383 buffers to a shell command.
2384 '\\[ibuffer-do-shell-command-pipe-replace]' - Replace the contents of the marked
2385 buffers with the output of a shell command.
2386 '\\[ibuffer-do-shell-command-file]' - Run a shell command with the
2387 buffer's file as an argument.
2388 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2389 is a very flexible command. For example, if you want to make all
2390 of the marked buffers read only, try using (toggle-read-only 1) as
2391 the input form.
2392 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2393 is evaluated.
2394 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,
2395 but don't kill the associated buffer.
2396 '\\[ibuffer-do-kill-on-deletion-marks]' - Kill all buffers marked for deletion.
2398 Marking commands:
2400 '\\[ibuffer-mark-forward]' - Mark the buffer at point.
2401 '\\[ibuffer-toggle-marks]' - Unmark all currently marked buffers, and mark
2402 all unmarked buffers.
2403 '\\[ibuffer-unmark-forward]' - Unmark the buffer at point.
2404 '\\[ibuffer-unmark-backward]' - Unmark the buffer at point, and move to the
2405 previous line.
2406 '\\[ibuffer-unmark-all]' - Unmark all marked buffers.
2407 '\\[ibuffer-mark-by-mode]' - Mark buffers by major mode.
2408 '\\[ibuffer-mark-unsaved-buffers]' - Mark all \"unsaved\" buffers.
2409 This means that the buffer is modified, and has an associated file.
2410 '\\[ibuffer-mark-modified-buffers]' - Mark all modified buffers,
2411 regardless of whether or not they have an associated file.
2412 '\\[ibuffer-mark-special-buffers]' - Mark all buffers whose name begins and
2413 ends with '*'.
2414 '\\[ibuffer-mark-dissociated-buffers]' - Mark all buffers which have
2415 an associated file, but that file doesn't currently exist.
2416 '\\[ibuffer-mark-read-only-buffers]' - Mark all read-only buffers.
2417 '\\[ibuffer-mark-dired-buffers]' - Mark buffers in `dired' mode.
2418 '\\[ibuffer-mark-help-buffers]' - Mark buffers in `help-mode', `apropos-mode', etc.
2419 '\\[ibuffer-mark-old-buffers]' - Mark buffers older than `ibuffer-old-time'.
2420 '\\[ibuffer-mark-for-delete]' - Mark the buffer at point for deletion.
2421 '\\[ibuffer-mark-by-name-regexp]' - Mark buffers by their name, using a regexp.
2422 '\\[ibuffer-mark-by-mode-regexp]' - Mark buffers by their major mode, using a regexp.
2423 '\\[ibuffer-mark-by-file-name-regexp]' - Mark buffers by their filename, using a regexp.
2425 Filtering commands:
2427 '\\[ibuffer-filter-by-mode]' - Add a filter by major mode.
2428 '\\[ibuffer-filter-by-used-mode]' - Add a filter by major mode now in use.
2429 '\\[ibuffer-filter-by-name]' - Add a filter by buffer name.
2430 '\\[ibuffer-filter-by-content]' - Add a filter by buffer content.
2431 '\\[ibuffer-filter-by-filename]' - Add a filter by filename.
2432 '\\[ibuffer-filter-by-size-gt]' - Add a filter by buffer size.
2433 '\\[ibuffer-filter-by-size-lt]' - Add a filter by buffer size.
2434 '\\[ibuffer-filter-by-predicate]' - Add a filter by an arbitrary Lisp predicate.
2435 '\\[ibuffer-save-filters]' - Save the current filters with a name.
2436 '\\[ibuffer-switch-to-saved-filters]' - Switch to previously saved filters.
2437 '\\[ibuffer-add-saved-filters]' - Add saved filters to current filters.

2482 '\\[ibuffer-bury-buffer]' - Bury (not kill!) the buffer on this line.
2484 ** Information on Filtering:
2486 You can filter your ibuffer view via different critera. Each Ibuffer
2487 buffer has its own stack of active filters. For example, suppose you
2488 are working on an Emacs Lisp project. You can create an Ibuffer
2489 buffer displays buffers in just `emacs-lisp' modes via
2490 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2491 is just one entry on the filtering stack.
2493 You can also combine filters. The various filtering commands push a
2494 new filter onto the stack, and the filters combine to show just
2495 buffers which satisfy ALL criteria on the stack. For example, suppose
2496 you only want to see buffers in `emacs-lisp' mode, whose names begin
2497 with \"gnus\". You can accomplish this via:
2498 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2499 \\[ibuffer-filter-by-name] ^gnus RET'.
2501 Additionally, you can OR the top two filters together with
2502 '\\[ibuffer-or-filters]'. To see all buffers in either
2503 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2505 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2507 Filters can also be saved and restored using mnemonic names: see the
2508 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2510 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2511 to disable all filtering currently in effect, use
2512 '\\[ibuffer-filter-disable]'.
2514 ** Filter Groups:
2516 Once one has mastered filters, the next logical step up is \"filter
2517 groups\". A filter group is basically a named group of buffers which
2518 match a filter, which are displayed together in an Ibuffer buffer. To
2519 create a filter group, simply use the regular functions to create a
2520 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2522 A quick example will make things clearer. Suppose that one wants to
2523 group all of one's Emacs Lisp buffers together. To do this, type
2525 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2527 You may, of course, name the group whatever you want; it doesn't have
2528 to be \"emacs lisp buffers\". Filter groups may be composed of any
2529 arbitrary combination of filters.
2531 Just like filters themselves, filter groups act as a stack. Buffers
2532 will not be displayed multiple times if they would be included in
2533 multiple filter groups; instead, the first filter group is used. The
2534 filter groups are displayed in this order of precedence.
2536 You may rearrange filter groups by using the regular
2537 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2538 will be inserted before the group at point."
