25 ;;; Commentary:
27 ;; ibuffer.el is an advanced replacement for the `buffer-menu' which
28 ;; is normally distributed with Emacs. Its interface is intended to
29 ;; be analogous to that of Dired.
31 ;;; Code:
42 ;; These come from ibuf-ext.el, which can not be require'd at compile time
43 ;; because it has a recursive dependency on ibuffer.el
67 "Advanced replacement for `buffer-menu'.
68 Ibuffer lets you operate on buffers in a Dired-like way,
69 with the ability to sort, mark by regular expression,
70 and filter displayed buffers by various criteria."
79 "A list of ways to display buffer lines.
81 With Ibuffer, you are not limited to displaying just certain
82 attributes of a buffer such as size, name, and mode in a particular
83 order. Through this variable, you can completely customize and
84 control the appearance of an Ibuffer buffer. See also
85 `define-ibuffer-column', which allows you to define your own columns
86 for display.
88 This variable has the form
89 ((COLUMN COLUMN ...) (COLUMN COLUMN ...) ...)
90 Each element in `ibuffer-formats' should be a list containing COLUMN
91 specifiers. A COLUMN can be any of the following:
93 SYMBOL - A symbol naming the column. Predefined columns are:
94 mark modified read-only name size mode process filename
95 When you define your own columns using `define-ibuffer-column', just
96 use their name like the predefined columns here. This entry can
97 also be a function of two arguments, which should return a string.
98 The first argument is the buffer object, and the second is the mark
99 on that buffer.
100 or
102 or
103 (SYMBOL MIN-SIZE MAX-SIZE &optional ALIGN ELIDE) - SYMBOL is a
104 symbol naming the column, and MIN-SIZE and MAX-SIZE are integers (or
105 functions of no arguments returning an integer) which constrict the
106 size of a column. If MAX-SIZE is -1, there is no upper bound. The
107 default values are 0 and -1, respectively. If MIN-SIZE is negative,
108 use the end of the string. The optional element ALIGN describes the
109 alignment of the column; it can be :left, :center or :right. The
110 optional element ELIDE describes whether or not to elide the column
111 if it is too long; valid values are :elide and nil. The default is
112 nil (don't elide).
114 Some example of valid entries in `ibuffer-formats', with
115 description (also, feel free to try them out, and experiment with your
116 own!):
119 This format just displays the current mark (if any) and the name of
120 the buffer, separated by a space.
122 This format displays the current mark (if any), its modification and
123 read-only status, as well as the name of the buffer and its size. In
124 this format, the name is restricted to 16 characters (longer names
125 will be truncated, and shorter names will be padded with spaces), and
126 the name is also aligned to the left. The size of the buffer will
127 be padded with spaces up to a minimum of six characters, but there is
128 no upper limit on its size. The size will also be aligned to the
129 right.
131 Thus, if you wanted to use these two formats, the appropriate
132 value for this variable would be
135 (mark modified read-only
136 (name 16 16 :left)
137 (size 6 -1 :right)))
140 the specified formats in the list."
146 "If non-nil, then use the byte-compiler to optimize `ibuffer-formats'.
147 This will increase the redisplay speed, at the cost of loading the
148 elisp byte-compiler."

165 "An alist describing how to fontify buffers.
166 Each element should be of the form (PRIORITY FORM FACE), where
167 PRIORITY is an integer, FORM is an arbitrary form to evaluate in the
168 buffer, and FACE is the face to use for fontification. If the FORM
169 evaluates to non-nil, then FACE will be put on the buffer name. The
170 element with the highest PRIORITY takes precedence.
172 If you change this variable, you must kill the Ibuffer buffer and
173 recreate it for the change to take effect."

197 "If non-nil, do not display continuation lines."
202 "If non-nil, ignore case when searching."
207 "The criteria by which to sort the buffers.
209 Note that this variable is local to each Ibuffer buffer. Thus, you
210 can have multiple Ibuffer buffers open, each with a different sorted
211 view of the buffers."
222 "If non-nil, reverse the default sorting order."

236 "The string to use for eliding long columns."
243 "A list of predicates for buffers to display conditionally.
245 A predicate can be a regexp or a function.
246 If a regexp, then it will be matched against the buffer's name.
247 If a function, it will be called with the buffer as an argument, and
248 should return non-nil if this buffer should be shown.
250 Viewing of buffers hidden because of these predicates may be customized
251 via `ibuffer-default-display-maybe-show-predicates' and is toggled by
252 giving a non-nil prefix argument to `ibuffer-update'.
253 Note that this specialized filtering occurs before real filtering."

287 "The character to display for locked buffers."
293 "The character to display for buffers marked for deletion."
303 "If non-nil, display the current Ibuffer buffer itself.
304 Note that this has a drawback - the data about the current Ibuffer
305 buffer will most likely be inaccurate. This includes modification
306 state, size, etc."
311 "If non-nil, always display the previous buffer.
312 This variable takes precedence over filtering, and even

321 in completion lists of the `ibuffer-jump-to-buffer' command."
326 "If non-nil, display a header line containing current filters."
331 "The default directory to use for a new Ibuffer buffer.
332 If nil, inherit the directory of the buffer in which `ibuffer' was
333 called. Otherwise, this variable should be a string naming a
334 directory, like `default-directory'."

2446 "A major mode for viewing a list of buffers.
2447 In Ibuffer, you can conveniently perform many operations on the
2448 currently open buffers, in addition to filtering your view to a
2449 particular subset of them, and sorting by various criteria.
2451 Operations on marked buffers:
2462 buffers.
2467 a given regexp (like the function `occur').
2469 buffers to a shell command.
2471 buffers with the output of a shell command.
2473 buffer's file as an argument.
2475 is a very flexible command. For example, if you want to make all
2476 of the marked buffers read only, try using (read-only-mode 1) as
2477 the input form.

2574 ** Information on Filtering:
2576 You can filter your ibuffer view via different criteria. Each Ibuffer
2577 buffer has its own stack of active filters. For example, suppose you
2578 are working on an Emacs Lisp project. You can create an Ibuffer
2579 buffer displays buffers in just `emacs-lisp' modes via
2581 is just one entry on the filtering stack.
2583 You can also combine filters. The various filtering commands push a
2584 new filter onto the stack, and the filters combine to show just
2585 buffers which satisfy ALL criteria on the stack. For example, suppose
2586 you only want to see buffers in `emacs-lisp' mode, whose names begin
2592 Additionally, you can OR the top two filters together with
2594 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2600 Filters can also be saved and restored using mnemonic names: see the
2601 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2604 to disable all filtering currently in effect, use
2607 ** Filter Groups:
2611 match a filter, which are displayed together in an Ibuffer buffer. To
2612 create a filter group, simply use the regular functions to create a
2615 A quick example will make things clearer. Suppose that one wants to
2616 group all of one's Emacs Lisp buffers together. To do this, type:
2621 You may, of course, name the group whatever you want; it doesn't have
2623 arbitrary combination of filters.
2625 Just like filters themselves, filter groups act as a stack. Buffers
2626 will not be displayed multiple times if they would be included in
2627 multiple filter groups; instead, the first filter group is used. The
2628 filter groups are displayed in this order of precedence.
2630 You may rearrange filter groups by using the regular
