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
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
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
112 Some example of valid entries in `ibuffer-formats', with

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
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))))

2378 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2379 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2380 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2381 '\\[ibuffer-do-isearch]' - Do incremental search in the marked buffers.

2395 buffer's file as an argument.
2396 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2397 is a very flexible command. For example, if you want to make all
2398 of the marked buffers read only, try using (toggle-read-only 1) as

2492 ** Information on Filtering:
2494 You can filter your ibuffer view via different critera. Each Ibuffer
2495 buffer has its own stack of active filters. For example, suppose you
2496 are working on an Emacs Lisp project. You can create an Ibuffer
2497 buffer displays buffers in just `emacs-lisp' modes via
2498 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2499 is just one entry on the filtering stack.
2501 You can also combine filters. The various filtering commands push a
2502 new filter onto the stack, and the filters combine to show just
2503 buffers which satisfy ALL criteria on the stack. For example, suppose
2504 you only want to see buffers in `emacs-lisp' mode, whose names begin
2505 with \"gnus\". You can accomplish this via:
2506 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2507 \\[ibuffer-filter-by-name] ^gnus RET'.
2509 Additionally, you can OR the top two filters together with
2510 '\\[ibuffer-or-filters]'. To see all buffers in either
2511 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2513 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2515 Filters can also be saved and restored using mnemonic names: see the
2516 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2518 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2519 to disable all filtering currently in effect, use
2520 '\\[ibuffer-filter-disable]'.
2524 Once one has mastered filters, the next logical step up is \"filter
2525 groups\". A filter group is basically a named group of buffers which
2526 match a filter, which are displayed together in an Ibuffer buffer. To
2527 create a filter group, simply use the regular functions to create a
2528 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2530 A quick example will make things clearer. Suppose that one wants to
2531 group all of one's Emacs Lisp buffers together. To do this, type
2533 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2535 You may, of course, name the group whatever you want; it doesn't have
2536 to be \"emacs lisp buffers\". Filter groups may be composed of any
2537 arbitrary combination of filters.
2539 Just like filters themselves, filter groups act as a stack. Buffers
2540 will not be displayed multiple times if they would be included in
2541 multiple filter groups; instead, the first filter group is used. The
2542 filter groups are displayed in this order of precedence.
2544 You may rearrange filter groups by using the regular
2545 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2546 will be inserted before the group at point."
