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
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
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

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
131 Thus, if you wanted to use these two formats, add
133 (setq ibuffer-formats '((mark \" \" name)

2359 particular subset of them, and sorting by various criteria.
2361 Operations on marked buffers:

2366 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2367 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.

2381 buffer's file as an argument.
2382 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2383 is a very flexible command. For example, if you want to make all
2384 of the marked buffers read only, try using (toggle-read-only 1) as
2386 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2388 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,

2478 ** Information on Filtering:
2480 You can filter your ibuffer view via different critera. Each Ibuffer
2481 buffer has its own stack of active filters. For example, suppose you
2482 are working on an Emacs Lisp project. You can create an Ibuffer
2483 buffer displays buffers in just `emacs-lisp' modes via
2484 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2485 is just one entry on the filtering stack.
2487 You can also combine filters. The various filtering commands push a
2488 new filter onto the stack, and the filters combine to show just
2489 buffers which satisfy ALL criteria on the stack. For example, suppose
2490 you only want to see buffers in `emacs-lisp' mode, whose names begin
2491 with \"gnus\". You can accomplish this via:
2492 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2493 \\[ibuffer-filter-by-name] ^gnus RET'.
2495 Additionally, you can OR the top two filters together with
2496 '\\[ibuffer-or-filters]'. To see all buffers in either
2497 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2499 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2501 Filters can also be saved and restored using mnemonic names: see the
2502 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2504 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2505 to disable all filtering currently in effect, use
2506 '\\[ibuffer-filter-disable]'.
2510 Once one has mastered filters, the next logical step up is \"filter
2511 groups\". A filter group is basically a named group of buffers which
2512 match a filter, which are displayed together in an Ibuffer buffer. To
2513 create a filter group, simply use the regular functions to create a
2514 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2516 A quick example will make things clearer. Suppose that one wants to
2517 group all of one's Emacs Lisp buffers together. To do this, type
2519 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2521 You may, of course, name the group whatever you want; it doesn't have
2522 to be \"emacs lisp buffers\". Filter groups may be composed of any
2523 arbitrary combination of filters.
2525 Just like filters themselves, filter groups act as a stack. Buffers
2526 will not be displayed multiple times if they would be included in
2527 multiple filter groups; instead, the first filter group is used. The
2528 filter groups are displayed in this order of precedence.
2530 You may rearrange filter groups by using the regular
2531 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2532 will be inserted before the group at point."
