54 Ibuffer allows you to operate on buffers in a manner much like Dired.
55 Operations include sorting, marking by regular expression, and
56 the ability to filter the displayed buffers by various criteria."

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

104 the buffer, separated by a space.
105 (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
106 This format displays the current mark (if any), its modification and
107 read-only status, as well as the name of the buffer and its size. In
108 this format, the name is restricted to 16 characters (longer names
109 will be truncated, and shorter names will be padded with spaces), and
110 the name is also aligned to the left. The size of the buffer will
111 be padded with spaces up to a minimum of six characters, but there is
112 no upper limit on its size. The size will also be aligned to the
115 Thus, if you wanted to use these two formats, add
117 (setq ibuffer-formats '((mark \" \" name)

2334 ** Information on Filtering:
2336 You can filter your ibuffer view via different critera. Each Ibuffer
2337 buffer has its own stack of active filters. For example, suppose you
2338 are working on an Emacs Lisp project. You can create an Ibuffer
2339 buffer displays buffers in just `emacs-lisp' modes via
2340 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2341 is just one entry on the filtering stack.
2343 You can also combine filters. The various filtering commands push a
2344 new filter onto the stack, and the filters combine to show just
2345 buffers which satisfy ALL criteria on the stack. For example, suppose
2346 you only want to see buffers in `emacs-lisp' mode, whose names begin
2347 with \"gnus\". You can accomplish this via:
2348 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2349 \\[ibuffer-filter-by-name] ^gnus RET'.
2351 Additionally, you can OR the top two filters together with
2352 '\\[ibuffer-or-filters]'. To see all buffers in either
2353 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2355 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2357 Filters can also be saved and restored using mnemonic names: see the
2358 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2360 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2361 to disable all filtering currently in effect, use
2362 '\\[ibuffer-filter-disable]'.
2366 Once one has mastered filters, the next logical step up is \"filter
2367 groups\". A filter group is basically a named group of buffers which
2368 match a filter, which are displayed together in an Ibuffer buffer. To
2369 create a filter group, simply use the regular functions to create a
2370 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2372 A quick example will make things clearer. Suppose that one wants to
2373 group all of one's Emacs Lisp buffers together. To do this, type
2375 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2377 You may, of course, name the group whatever you want; it doesn't have
2378 to be \"emacs lisp buffers\". Filter groups may be composed of any
2379 arbitrary combination of filters.
2381 Just like filters themselves, filter groups act as a stack. Buffers
2382 will not be displayed multiple times if they would be included in
2383 multiple filter groups; instead, the first filter group is used. The
2384 filter groups are displayed in this order of precedence.
2386 You may rearrange filter groups by using the regular
2387 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2388 will be inserted before the group at point."
