76 "A list of ways to display buffer lines.
78 With Ibuffer, you are not limited to displaying just certain
79 attributes of a buffer such as size, name, and mode in a particular
80 order. Through this variable, you can completely customize and
81 control the appearance of an Ibuffer buffer. See also
82 `define-ibuffer-column', which allows you to define your own columns
85 This variable has the form
86 ((COLUMN COLUMN ...) (COLUMN COLUMN ...) ...)
87 Each element in `ibuffer-formats' should be a list containing COLUMN
88 specifiers. A COLUMN can be any of the following:
90 SYMBOL - A symbol naming the column. Predefined columns are:
91 mark modified read-only name size mode process filename
92 When you define your own columns using `define-ibuffer-column', just
93 use their name like the predefined columns here. This entry can
94 also be a function of two arguments, which should return a string.
95 The first argument is the buffer object, and the second is the mark
98 \"STRING\" - A literal string to display.
100 (SYMBOL MIN-SIZE MAX-SIZE &optional ALIGN ELIDE) - SYMBOL is a
101 symbol naming the column, and MIN-SIZE and MAX-SIZE are integers (or
102 functions of no arguments returning an integer) which constrict the
103 size of a column. If MAX-SIZE is -1, there is no upper bound. The
104 default values are 0 and -1, respectively. If MIN-SIZE is negative,
105 use the end of the string. The optional element ALIGN describes the
106 alignment of the column; it can be :left, :center or :right. The
107 optional element ELIDE describes whether or not to elide the column
108 if it is too long; valid values are :elide and nil. The default is

117 the buffer, separated by a space.
118 (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
119 This format displays the current mark (if any), its modification and
120 read-only status, as well as the name of the buffer and its size. In
121 this format, the name is restricted to 16 characters (longer names
122 will be truncated, and shorter names will be padded with spaces), and
123 the name is also aligned to the left. The size of the buffer will
124 be padded with spaces up to a minimum of six characters, but there is
125 no upper limit on its size. The size will also be aligned to the
128 Thus, if you wanted to use these two formats, the appropriate
129 value for this variable would be

2495 ** Information on Filtering:
2497 You can filter your ibuffer view via different criteria. Each Ibuffer
2498 buffer has its own stack of active filters. For example, suppose you
2499 are working on an Emacs Lisp project. You can create an Ibuffer
2500 buffer displays buffers in just `emacs-lisp' modes via
2501 `\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2502 is just one entry on the filtering stack.
2504 You can also combine filters. The various filtering commands push a
2505 new filter onto the stack, and the filters combine to show just
2506 buffers which satisfy ALL criteria on the stack. For example, suppose
2507 you only want to see buffers in `emacs-lisp' mode, whose names begin
2508 with \"gnus\". You can accomplish this via:
2510 \\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2511 \\[ibuffer-filter-by-name] ^gnus RET
2513 Additionally, you can OR the top two filters together with
2514 `\\[ibuffer-or-filters]'. To see all buffers in either
2515 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2517 \\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2518 \\[ibuffer-filter-by-mode] lisp-interaction-mode RET
2519 \\[ibuffer-or-filters]
2521 Filters can also be saved and restored using mnemonic names: see the
2522 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2524 To remove the top filter on the stack, use `\\[ibuffer-pop-filter]', and
2525 to disable all filtering currently in effect, use
2526 `\\[ibuffer-filter-disable]'.
2530 Once one has mastered filters, the next logical step up is \"filter
2531 groups\". A filter group is basically a named group of buffers which
2532 match a filter, which are displayed together in an Ibuffer buffer. To
2533 create a filter group, simply use the regular functions to create a
2534 filter, and then type `\\[ibuffer-filters-to-filter-group]'.
2536 A quick example will make things clearer. Suppose that one wants to
2537 group all of one's Emacs Lisp buffers together. To do this, type:
2539 \\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2540 \\[ibuffer-filters-to-filter-group] emacs lisp buffers RET
2542 You may, of course, name the group whatever you want; it doesn't have
2543 to be \"emacs lisp buffers\". Filter groups may be composed of any
2544 arbitrary combination of filters.
2546 Just like filters themselves, filter groups act as a stack. Buffers
2547 will not be displayed multiple times if they would be included in
2548 multiple filter groups; instead, the first filter group is used. The
2549 filter groups are displayed in this order of precedence.
2551 You may rearrange filter groups by using the regular
2552 `\\[ibuffer-kill-line]' and `\\[ibuffer-yank]' pair. Yanked groups
2553 will be inserted before the group at point."
