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

64 "A list of ways to display buffer lines.
66 With Ibuffer, you are not limited to displaying just certain
67 attributes of a buffer such as size, name, and mode in a particular
68 order. Through this variable, you can completely customize and
69 control the appearance of an Ibuffer buffer. See also
70 `define-ibuffer-column', which allows you to define your own columns
71 for display.
73 This variable has the form
74 ((COLUMN COLUMN ...) (COLUMN COLUMN ...) ...)
75 Each element in `ibuffer-formats' should be a list containing COLUMN
76 specifiers. A COLUMN can be any of the following:
78 SYMBOL - A symbol naming the column. Predefined columns are:
79 mark modified read-only name size mode process filename
80 When you define your own columns using `define-ibuffer-column', just
81 use their name like the predefined columns here. This entry can
82 also be a function of two arguments, which should return a string.
83 The first argument is the buffer object, and the second is the mark
84 on that buffer.
86 \"STRING\" - A literal string to display.
88 (SYMBOL MIN-SIZE MAX-SIZE &optional ALIGN ELIDE) - SYMBOL is a
89 symbol naming the column, and MIN-SIZE and MAX-SIZE are integers (or
90 functions of no arguments returning an integer) which constrict the
91 size of a column. If MAX-SIZE is -1, there is no upper bound. The
92 default values are 0 and -1, respectively. If MIN-SIZE is negative,
93 use the end of the string. The optional element ALIGN describes the
94 alignment of the column; it can be :left, :center or :right. The
95 optional element ELIDE describes whether or not to elide the column
96 if it is too long; valid values are :elide and nil. The default is
97 nil (don't elide).
99 Some example of valid entries in `ibuffer-formats', with
100 description (also, feel free to try them out, and experiment with your
101 own!):
103 (mark \" \" name)
104 This format just displays the current mark (if any) and the name of
105 the buffer, separated by a space.
106 (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
107 This format displays the current mark (if any), its modification and
108 read-only status, as well as the name of the buffer and its size. In
109 this format, the name is restricted to 16 characters (longer names
110 will be truncated, and shorter names will be padded with spaces), and
111 the name is also aligned to the left. The size of the buffer will
112 be padded with spaces up to a minimum of six characters, but there is
113 no upper limit on its size. The size will also be aligned to the
114 right.
116 Thus, if you wanted to use these two formats, add
118 (setq ibuffer-formats '((mark \" \" name)
119 (mark modified read-only
120 (name 16 16 :left) (size 6 -1 :right))))
122 to your ~/.emacs file.
124 Using \\[ibuffer-switch-format], you can rotate the display between
125 the specified formats in the list."

2208 In ibuffer, you can conveniently perform many operations on the
2209 currently open buffers, in addition to filtering your view to a
2210 particular subset of them, and sorting by various criteria.
2212 Operations on marked buffers:
2214 '\\[ibuffer-do-save]' - Save the marked buffers
2215 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2216 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2217 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2218 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2219 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2220 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
2221 buffers.
2222 '\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
2223 '\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
2224 '\\[ibuffer-do-print]' - Print the marked buffers.
2225 '\\[ibuffer-do-occur]' - List lines in all marked buffers which match
2226 a given regexp (like the function `occur').

2229 '\\[ibuffer-do-shell-command-pipe-replace]' - Replace the contents of the marked
2230 buffers with the output of a shell command.
2231 '\\[ibuffer-do-shell-command-file]' - Run a shell command with the
2232 buffer's file as an argument.
2233 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2234 is a very flexible command. For example, if you want to make all
2235 of the marked buffers read only, try using (toggle-read-only 1) as
2236 the input form.
2237 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2238 is evaluated.
2239 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,
2240 but don't kill the associated buffer.
2241 '\\[ibuffer-do-kill-on-deletion-marks]' - Kill all buffers marked for deletion.
2243 Marking commands:
2245 '\\[ibuffer-mark-forward]' - Mark the buffer at point.

2256 regardless of whether or not they have an associated file.
2257 '\\[ibuffer-mark-special-buffers]' - Mark all buffers whose name begins and
2258 ends with '*'.
2259 '\\[ibuffer-mark-dissociated-buffers]' - Mark all buffers which have
2260 an associated file, but that file doesn't currently exist.
2261 '\\[ibuffer-mark-read-only-buffers]' - Mark all read-only buffers.
2262 '\\[ibuffer-mark-dired-buffers]' - Mark buffers in `dired' mode.

2323 '\\[ibuffer-bury-buffer]' - Bury (not kill!) the buffer on this line.
2325 ** Information on Filtering:
2327 You can filter your ibuffer view via different critera. Each Ibuffer
2328 buffer has its own stack of active filters. For example, suppose you
2329 are working on an Emacs Lisp project. You can create an Ibuffer
2330 buffer displays buffers in just `emacs-lisp' modes via
2331 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2332 is just one entry on the filtering stack.
2334 You can also combine filters. The various filtering commands push a
2335 new filter onto the stack, and the filters combine to show just
2336 buffers which satisfy ALL criteria on the stack. For example, suppose
2337 you only want to see buffers in `emacs-lisp' mode, whose names begin
2338 with \"gnus\". You can accomplish this via:
2339 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2340 \\[ibuffer-filter-by-name] ^gnus RET'.
2342 Additionally, you can OR the top two filters together with
2343 '\\[ibuffer-or-filters]'. To see all buffers in either
2344 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2346 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2348 Filters can also be saved and restored using mnemonic names: see the
2349 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2351 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2352 to disable all filtering currently in effect, use
2353 '\\[ibuffer-filter-disable]'.
2355 ** Filter Groups:
2357 Once one has mastered filters, the next logical step up is \"filter
2358 groups\". A filter group is basically a named group of buffers which
2359 match a filter, which are displayed together in an Ibuffer buffer. To
2360 create a filter group, simply use the regular functions to create a
2361 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2363 A quick example will make things clearer. Suppose that one wants to
2364 group all of one's Emacs Lisp buffers together. To do this, type
2366 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2368 You may, of course, name the group whatever you want; it doesn't have
2369 to be \"emacs lisp buffers\". Filter groups may be composed of any
2370 arbitrary combination of filters.
2372 Just like filters themselves, filter groups act as a stack. Buffers
2373 will not be displayed multiple times if they would be included in
2374 multiple filter groups; instead, the first filter group is used. The
2375 filter groups are displayed in this order of precedence.
2377 You may rearrange filter groups by using the regular
2378 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2379 will be inserted before the group at point."
