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

112 This format just displays the current mark (if any) and the name of
113 the buffer, separated by a space.
114 (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
115 This format displays the current mark (if any), its modification and
116 read-only status, as well as the name of the buffer and its size. In
117 this format, the name is restricted to 16 characters (longer names
118 will be truncated, and shorter names will be padded with spaces), and
119 the name is also aligned to the right. The size of the buffer will
120 be padded with spaces up to a minimum of six characters, but there is
121 no upper limit on its size. The size will also be aligned to the
124 Thus, if you wanted to use these two formats, add
126 (setq ibuffer-formats '((mark \" \" name)

2086 buffer's file as an argument.
2087 '\\[ibuffer-do-eval]' - Evaluate a form in each of the marked buffers. This
2088 is a very flexible command. For example, if you want to make all
2089 of the marked buffers read only, try using (toggle-read-only 1) as
2091 '\\[ibuffer-do-view-and-eval]' - As above, but view each buffer while the form
2093 '\\[ibuffer-do-kill-lines]' - Remove the marked lines from the *Ibuffer* buffer,

2106 '\\[ibuffer-mark-by-mode]' - Mark buffers by major mode.
2107 '\\[ibuffer-mark-unsaved-buffers]' - Mark all \"unsaved\" buffers.
2108 This means that the buffer is modified, and has an associated file.
2109 '\\[ibuffer-mark-modified-buffers]' - Mark all modified buffers,
2110 regardless of whether or not they have an associated file.
2111 '\\[ibuffer-mark-special-buffers]' - Mark all buffers whose name begins and
2113 '\\[ibuffer-mark-dissociated-buffers]' - Mark all buffers which have
2114 an associated file, but that file doesn't currently exist.
2115 '\\[ibuffer-mark-read-only-buffers]' - Mark all read-only buffers.
2116 '\\[ibuffer-mark-dired-buffers]' - Mark buffers in `dired' mode.
2117 '\\[ibuffer-mark-help-buffers]' - Mark buffers in `help-mode', `apropos-mode', etc.

2165 '\\[ibuffer-bury-buffer]' - Bury (not kill!) the buffer on this line.
2167 Information on Filtering:
2169 You can filter your ibuffer view via different critera. Each Ibuffer
2170 buffer has its own stack of active filters. For example, suppose you
2171 are working on an Emacs Lisp project. You can create an Ibuffer
2172 buffer displays buffers in just `emacs-lisp' modes via
2173 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there
2174 is just one entry on the filtering stack.
2176 You can also combine filters. The various filtering commands push a
2177 new filter onto the stack, and the filters combine to show just
2178 buffers which satisfy ALL criteria on the stack. For example, suppose
2179 you only want to see buffers in `emacs-lisp' mode, whose names begin
2180 with \"gnus\". You can accomplish this via:
2181 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET
2182 \\[ibuffer-filter-by-name] ^gnus RET'.
2184 Additionally, you can OR the top two filters together with
2185 '\\[ibuffer-or-filters]'. To see all buffers in either
2186 `emacs-lisp-mode' or `lisp-interaction-mode', type:
2188 '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'.
2190 Filters can also be saved and restored using mnemonic names: see the
2191 functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'.
2193 To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and
2194 to disable all filtering currently in effect, use
2195 '\\[ibuffer-filter-disable]'."
