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

2374 In Ibuffer, you can conveniently perform many operations on the
2375 currently open buffers, in addition to filtering your view to a
2376 particular subset of them, and sorting by various criteria.
2378 Operations on marked buffers:
2380 '\\[ibuffer-do-save]' - Save the marked buffers
2381 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2382 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2383 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2384 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2385 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2386 '\\[ibuffer-do-isearch]' - Do incremental search in the marked buffers.
2387 '\\[ibuffer-do-isearch-regexp]' - Isearch for regexp in the marked buffers.
2388 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
2389 buffers.
2390 '\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
2391 '\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
2392 '\\[ibuffer-do-print]' - Print the marked buffers.
2393 '\\[ibuffer-do-occur]' - List lines in all marked buffers which match
2394 a given regexp (like the function `occur').
2395 '\\[ibuffer-do-shell-command-pipe]' - Pipe the contents of the marked
2396 buffers to a shell command.
2397 '\\[ibuffer-do-shell-command-pipe-replace]' - Replace the contents of the marked
2398 buffers with the output of a shell command.
2399 '\\[ibuffer-do-shell-command-file]' - Run a shell command with the
2400 buffer's file as an argument.
2401 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2402 is a very flexible command. For example, if you want to make all
2403 of the marked buffers read only, try using (toggle-read-only 1) as
2404 the input form.
2405 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2406 is evaluated.
2407 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,
2408 but don't kill the associated buffer.
2409 '\\[ibuffer-do-kill-on-deletion-marks]' - Kill all buffers marked for deletion.
2411 Marking commands:
2413 '\\[ibuffer-mark-forward]' - Mark the buffer at point.
2414 '\\[ibuffer-toggle-marks]' - Unmark all currently marked buffers, and mark
2415 all unmarked buffers.
2416 '\\[ibuffer-unmark-forward]' - Unmark the buffer at point.
2417 '\\[ibuffer-unmark-backward]' - Unmark the buffer at point, and move to the
2418 previous line.
2419 '\\[ibuffer-unmark-all]' - Unmark all marked buffers.
2420 '\\[ibuffer-mark-by-mode]' - Mark buffers by major mode.
2421 '\\[ibuffer-mark-unsaved-buffers]' - Mark all \"unsaved\" buffers.
2422 This means that the buffer is modified, and has an associated file.
2423 '\\[ibuffer-mark-modified-buffers]' - Mark all modified buffers,
2424 regardless of whether or not they have an associated file.
2425 '\\[ibuffer-mark-special-buffers]' - Mark all buffers whose name begins and
2426 ends with '*'.
2427 '\\[ibuffer-mark-dissociated-buffers]' - Mark all buffers which have
2428 an associated file, but that file doesn't currently exist.
2429 '\\[ibuffer-mark-read-only-buffers]' - Mark all read-only buffers.
2430 '\\[ibuffer-mark-dired-buffers]' - Mark buffers in `dired' mode.
2431 '\\[ibuffer-mark-help-buffers]' - Mark buffers in `help-mode', `apropos-mode', etc.
2432 '\\[ibuffer-mark-old-buffers]' - Mark buffers older than `ibuffer-old-time'.
2433 '\\[ibuffer-mark-for-delete]' - Mark the buffer at point for deletion.
2434 '\\[ibuffer-mark-by-name-regexp]' - Mark buffers by their name, using a regexp.
2435 '\\[ibuffer-mark-by-mode-regexp]' - Mark buffers by their major mode, using a regexp.

2443 '\\[ibuffer-filter-by-content]' - Add a filter by buffer content.
2444 '\\[ibuffer-filter-by-filename]' - Add a filter by filename.
2445 '\\[ibuffer-filter-by-size-gt]' - Add a filter by buffer size.
2446 '\\[ibuffer-filter-by-size-lt]' - Add a filter by buffer size.
2447 '\\[ibuffer-filter-by-predicate]' - Add a filter by an arbitrary Lisp predicate.
2448 '\\[ibuffer-save-filters]' - Save the current filters with a name.
2449 '\\[ibuffer-switch-to-saved-filters]' - Switch to previously saved filters.
2450 '\\[ibuffer-add-saved-filters]' - Add saved filters to current filters.

2497 ** Information on Filtering:
2499 You can filter your ibuffer view via different critera. Each Ibuffer
2500 buffer has its own stack of active filters. For example, suppose you
2501 are working on an Emacs Lisp project. You can create an Ibuffer
2502 buffer displays buffers in just `emacs-lisp' modes via
2503 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2504 is just one entry on the filtering stack.
2506 You can also combine filters. The various filtering commands push a
2507 new filter onto the stack, and the filters combine to show just
2508 buffers which satisfy ALL criteria on the stack. For example, suppose
2509 you only want to see buffers in `emacs-lisp' mode, whose names begin
2510 with \"gnus\". You can accomplish this via:
2511 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2512 \\[ibuffer-filter-by-name] ^gnus RET'.
2514 Additionally, you can OR the top two filters together with
2515 '\\[ibuffer-or-filters]'. To see all buffers in either
2516 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2518 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2520 Filters can also be saved and restored using mnemonic names: see the
2521 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2523 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2524 to disable all filtering currently in effect, use
2525 '\\[ibuffer-filter-disable]'.
2527 ** Filter Groups:
2529 Once one has mastered filters, the next logical step up is \"filter
2530 groups\". A filter group is basically a named group of buffers which
2531 match a filter, which are displayed together in an Ibuffer buffer. To
2532 create a filter group, simply use the regular functions to create a
2533 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2535 A quick example will make things clearer. Suppose that one wants to
2536 group all of one's Emacs Lisp buffers together. To do this, type
2538 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2540 You may, of course, name the group whatever you want; it doesn't have
2541 to be \"emacs lisp buffers\". Filter groups may be composed of any
2542 arbitrary combination of filters.
2544 Just like filters themselves, filter groups act as a stack. Buffers
2545 will not be displayed multiple times if they would be included in
2546 multiple filter groups; instead, the first filter group is used. The
2547 filter groups are displayed in this order of precedence.
2549 You may rearrange filter groups by using the regular
2550 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2551 will be inserted before the group at point."
