44 "An advanced replacement for `buffer-menu'.
46 Ibuffer allows you to operate on buffers in a manner much like Dired.
47 Operations include sorting, marking by regular expression, and
48 the ability to filter the displayed buffers by various criteria."

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

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

2304 In Ibuffer, you can conveniently perform many operations on the
2305 currently open buffers, in addition to filtering your view to a
2306 particular subset of them, and sorting by various criteria.
2308 Operations on marked buffers:
2310 '\\[ibuffer-do-save]' - Save the marked buffers
2311 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2312 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2313 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2314 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2315 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2316 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
2318 '\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
2319 '\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
2320 '\\[ibuffer-do-print]' - Print the marked buffers.
2321 '\\[ibuffer-do-occur]' - List lines in all marked buffers which match

2327 '\\[ibuffer-do-shell-command-file]' - Run a shell command with the
2328 buffer's file as an argument.
2329 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2330 is a very flexible command. For example, if you want to make all
2331 of the marked buffers read only, try using (toggle-read-only 1) as
2333 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2335 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,

2421 ** Information on Filtering:
2423 You can filter your ibuffer view via different critera. Each Ibuffer
2424 buffer has its own stack of active filters. For example, suppose you
2425 are working on an Emacs Lisp project. You can create an Ibuffer
2426 buffer displays buffers in just `emacs-lisp' modes via
2427 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2428 is just one entry on the filtering stack.
2430 You can also combine filters. The various filtering commands push a
2431 new filter onto the stack, and the filters combine to show just
2432 buffers which satisfy ALL criteria on the stack. For example, suppose
2433 you only want to see buffers in `emacs-lisp' mode, whose names begin
2434 with \"gnus\". You can accomplish this via:
2435 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2436 \\[ibuffer-filter-by-name] ^gnus RET'.
2438 Additionally, you can OR the top two filters together with
2439 '\\[ibuffer-or-filters]'. To see all buffers in either
2440 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2442 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2444 Filters can also be saved and restored using mnemonic names: see the
2445 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2447 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2448 to disable all filtering currently in effect, use
2449 '\\[ibuffer-filter-disable]'.
2453 Once one has mastered filters, the next logical step up is \"filter
2454 groups\". A filter group is basically a named group of buffers which
2455 match a filter, which are displayed together in an Ibuffer buffer. To
2456 create a filter group, simply use the regular functions to create a
2457 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2459 A quick example will make things clearer. Suppose that one wants to
2460 group all of one's Emacs Lisp buffers together. To do this, type
2462 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2464 You may, of course, name the group whatever you want; it doesn't have
2465 to be \"emacs lisp buffers\". Filter groups may be composed of any
2466 arbitrary combination of filters.
2468 Just like filters themselves, filter groups act as a stack. Buffers
2469 will not be displayed multiple times if they would be included in
2470 multiple filter groups; instead, the first filter group is used. The
2471 filter groups are displayed in this order of precedence.
2473 You may rearrange filter groups by using the regular
2474 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2475 will be inserted before the group at point."
