27 ;;; Commentary:
29 ;; ibuffer.el is an advanced replacement for the `buffer-menu' which
30 ;; is normally distributed with Emacs. Its interface is intended to
31 ;; be analogous to that of Dired.

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

50 (defcustom ibuffer-formats '((mark modified read-only " " (name 16 16 :left :elide)
51 " " (size 7 -1 :right)

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

2212 In ibuffer, you can conveniently perform many operations on the
2213 currently open buffers, in addition to filtering your view to a
2214 particular subset of them, and sorting by various criteria.
2216 Operations on marked buffers:
2218 '\\[ibuffer-do-save]' - Save the marked buffers
2219 '\\[ibuffer-do-view]' - View the marked buffers in this frame.
2220 '\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2221 '\\[ibuffer-do-revert]' - Revert the marked buffers.
2222 '\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2223 '\\[ibuffer-do-delete]' - Kill the marked buffers.
2224 '\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
2225 buffers.
2226 '\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
2227 '\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
2228 '\\[ibuffer-do-print]' - Print the marked buffers.
2229 '\\[ibuffer-do-occur]' - List lines in all marked buffers which match
2230 a given regexp (like the function `occur').

2233 '\\[ibuffer-do-shell-command-pipe-replace]' - Replace the contents of the marked
2234 buffers with the output of a shell command.
2235 '\\[ibuffer-do-shell-command-file]' - Run a shell command with the
2236 buffer's file as an argument.
2237 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2238 is a very flexible command. For example, if you want to make all
2239 of the marked buffers read only, try using (toggle-read-only 1) as
2240 the input form.
2241 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2242 is evaluated.
2243 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,
2244 but don't kill the associated buffer.
2245 '\\[ibuffer-do-kill-on-deletion-marks]' - Kill all buffers marked for deletion.
2247 Marking commands:
2249 '\\[ibuffer-mark-forward]' - Mark the buffer at point.

2260 regardless of whether or not they have an associated file.
2261 '\\[ibuffer-mark-special-buffers]' - Mark all buffers whose name begins and
2262 ends with '*'.
2263 '\\[ibuffer-mark-dissociated-buffers]' - Mark all buffers which have
2264 an associated file, but that file doesn't currently exist.
2265 '\\[ibuffer-mark-read-only-buffers]' - Mark all read-only buffers.
2266 '\\[ibuffer-mark-dired-buffers]' - Mark buffers in `dired' mode.

2329 ** Information on Filtering:
2331 You can filter your ibuffer view via different critera. Each Ibuffer
2332 buffer has its own stack of active filters. For example, suppose you
2333 are working on an Emacs Lisp project. You can create an Ibuffer
2334 buffer displays buffers in just `emacs-lisp' modes via
2335 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2336 is just one entry on the filtering stack.
2338 You can also combine filters. The various filtering commands push a
2339 new filter onto the stack, and the filters combine to show just
2340 buffers which satisfy ALL criteria on the stack. For example, suppose
2341 you only want to see buffers in `emacs-lisp' mode, whose names begin
2342 with \"gnus\". You can accomplish this via:
2343 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2344 \\[ibuffer-filter-by-name] ^gnus RET'.
2346 Additionally, you can OR the top two filters together with
2347 '\\[ibuffer-or-filters]'. To see all buffers in either
2348 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2350 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2352 Filters can also be saved and restored using mnemonic names: see the
2353 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2355 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2356 to disable all filtering currently in effect, use
2357 '\\[ibuffer-filter-disable]'.
2359 ** Filter Groups:
2361 Once one has mastered filters, the next logical step up is \"filter
2362 groups\". A filter group is basically a named group of buffers which
2363 match a filter, which are displayed together in an Ibuffer buffer. To
2364 create a filter group, simply use the regular functions to create a
2365 filter, and then type '\\[ibuffer-filters-to-filter-group]'.
2367 A quick example will make things clearer. Suppose that one wants to
2368 group all of one's Emacs Lisp buffers together. To do this, type
2370 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filters-to-filter-group] RET emacs lisp buffers RET'
2372 You may, of course, name the group whatever you want; it doesn't have
2373 to be \"emacs lisp buffers\". Filter groups may be composed of any
2374 arbitrary combination of filters.
2376 Just like filters themselves, filter groups act as a stack. Buffers
2377 will not be displayed multiple times if they would be included in
2378 multiple filter groups; instead, the first filter group is used. The
2379 filter groups are displayed in this order of precedence.
2381 You may rearrange filter groups by using the regular
2382 '\\[ibuffer-kill-line]' and '\\[ibuffer-yank]' pair. Yanked groups
2383 will be inserted before the group at point."
