27 ;; ibuffer.el is an advanced replacement for the `buffer-menu' which

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 locked 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.
101 \"STRING\" - A literal string to display.
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!):
118 (mark \" \" name)
119 This format just displays the current mark (if any) and the name of
120 the buffer, separated by a space.
121 (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
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
134 \\='((mark \" \" name)
135 (mark modified read-only
136 (name 16 16 :left)
137 (size 6 -1 :right)))
139 Using \\[ibuffer-switch-format], you can rotate the display between
140 the specified formats in the list."

2505 "A major mode for viewing a list of buffers.
2506 In Ibuffer, you can conveniently perform many operations on the
2507 currently open buffers, in addition to filtering your view to a
2508 particular subset of them, and sorting by various criteria.
2510 Operations on marked buffers:
2511 \\<ibuffer-mode-map>
2512 `\\[ibuffer-do-save]' - Save the marked buffers
2513 `\\[ibuffer-do-view]' - View the marked buffers in this frame.
2514 `\\[ibuffer-do-view-other-frame]' - View the marked buffers in another frame.
2515 `\\[ibuffer-do-revert]' - Revert the marked buffers.
2516 `\\[ibuffer-do-toggle-read-only]' - Toggle read-only state of marked buffers.
2517 `\\[ibuffer-do-delete]' - Kill the marked buffers.
2518 `\\[ibuffer-do-isearch]' - Do incremental search in the marked buffers.
2519 `\\[ibuffer-do-isearch-regexp]' - Isearch for regexp in the marked buffers.
2520 `\\[ibuffer-do-replace-regexp]' - Replace by regexp in each of the marked
2521 buffers.
2522 `\\[ibuffer-do-query-replace]' - Query replace in each of the marked buffers.
2523 `\\[ibuffer-do-query-replace-regexp]' - As above, with a regular expression.
2524 `\\[ibuffer-do-print]' - Print the marked buffers.
2525 `\\[ibuffer-do-occur]' - List lines in all marked buffers which match
2526 a given regexp (like the function `occur').
2527 `\\[ibuffer-do-shell-command-pipe]' - Pipe the contents of the marked
2528 buffers to a shell command.

2532 buffer's file as an argument.
2533 `\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This

2535 of the marked buffers read only, try using (read-only-mode 1) as
2536 the input form.
2537 `\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2538 is evaluated.
2539 `\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,
2540 but don't kill the associated buffer.

2558 regardless of whether or not they have an associated file.

2641 ** Information on Filtering:
2643 You can filter your ibuffer view via different criteria. Each Ibuffer
2644 buffer has its own stack of active filters. For example, suppose you
2645 are working on an Emacs Lisp project. You can create an Ibuffer
2646 buffer displays buffers in just `emacs-lisp' modes via
2647 `\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2648 is just one entry on the filtering stack.
2650 You can also combine filters. The various filtering commands push a
2651 new filter onto the stack, and the filters combine to show just
2652 buffers which satisfy ALL criteria on the stack. For example, suppose
2653 you only want to see buffers in `emacs-lisp' mode, whose names begin
2654 with \"gnus\". You can accomplish this via:
2656 \\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2657 \\[ibuffer-filter-by-name] ^gnus RET
2659 Additionally, you can OR the top two filters together with
2660 `\\[ibuffer-or-filters]'. To see all buffers in either
2661 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2663 \\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2664 \\[ibuffer-filter-by-mode] lisp-interaction-mode RET
2665 \\[ibuffer-or-filters]
2667 Filters can also be saved and restored using mnemonic names: see the
2668 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2670 To remove the top filter on the stack, use `\\[ibuffer-pop-filter]', and
2671 to disable all filtering currently in effect, use
2672 `\\[ibuffer-filter-disable]'.
2674 ** Filter Groups:
2676 Once one has mastered filters, the next logical step up is \"filter
2677 groups\". A filter group is basically a named group of buffers which
2678 match a filter, which are displayed together in an Ibuffer buffer. To
2679 create a filter group, simply use the regular functions to create a
2680 filter, and then type `\\[ibuffer-filters-to-filter-group]'.
2682 A quick example will make things clearer. Suppose that one wants to
2683 group all of one's Emacs Lisp buffers together. To do this, type:
2685 \\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2686 \\[ibuffer-filters-to-filter-group] emacs lisp buffers RET
2688 You may, of course, name the group whatever you want; it doesn't have
2689 to be \"emacs lisp buffers\". Filter groups may be composed of any
2690 arbitrary combination of filters.
2692 Just like filters themselves, filter groups act as a stack. Buffers
2693 will not be displayed multiple times if they would be included in
2694 multiple filter groups; instead, the first filter group is used. The
2695 filter groups are displayed in this order of precedence.
2697 You may rearrange filter groups by using the regular
2698 `\\[ibuffer-kill-line]' and `\\[ibuffer-yank]' pair. Yanked groups
2699 will be inserted before the group at point."
