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

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

2502 ** Information on Filtering:
2504 You can filter your ibuffer view via different criteria. Each Ibuffer
2505 buffer has its own stack of active filters. For example, suppose you
2506 are working on an Emacs Lisp project. You can create an Ibuffer
2507 buffer displays buffers in just `emacs-lisp' modes via
2508 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2509 is just one entry on the filtering stack.
2511 You can also combine filters. The various filtering commands push a
2512 new filter onto the stack, and the filters combine to show just
2513 buffers which satisfy ALL criteria on the stack. For example, suppose
2514 you only want to see buffers in `emacs-lisp' mode, whose names begin
2515 with \"gnus\". You can accomplish this via:
2516 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2517 \\[ibuffer-filter-by-name] ^gnus RET'.
2519 Additionally, you can OR the top two filters together with
2520 '\\[ibuffer-or-filters]'. To see all buffers in either
2521 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2523 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2525 Filters can also be saved and restored using mnemonic names: see the
2526 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2528 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2529 to disable all filtering currently in effect, use
2530 '\\[ibuffer-filter-disable]'.
2534 Once one has mastered filters, the next logical step up is \"filter
2535 groups\". A filter group is basically a named group of buffers which
2536 match a filter, which are displayed together in an Ibuffer buffer. To
2537 create a filter group, simply use the regular functions to create a
2538 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2540 A quick example will make things clearer. Suppose that one wants to
2541 group all of one's Emacs Lisp buffers together. To do this, type
2543 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2545 You may, of course, name the group whatever you want; it doesn't have
2546 to be \"emacs lisp buffers\". Filter groups may be composed of any
2547 arbitrary combination of filters.
2549 Just like filters themselves, filter groups act as a stack. Buffers
2550 will not be displayed multiple times if they would be included in
2551 multiple filter groups; instead, the first filter group is used. The
2552 filter groups are displayed in this order of precedence.
2554 You may rearrange filter groups by using the regular
2555 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2556 will be inserted before the group at point."
