+ "An advanced replacement for `buffer-menu'.
+
+ Ibuffer allows you to operate on buffers in a manner much like Dired.
+ Operations include sorting, marking by regular expression, and
+ the ability to filter the displayed buffers by various criteria."
+ :group 'convenience)
+
+ (defcustom ibuffer-formats '((mark modified read-only " " (name 18 18 :left
:elide)

+ "A list of ways to display buffer lines.
+
+ With Ibuffer, you are not limited to displaying just certain
+ attributes of a buffer such as size, name, and mode in a particular
+ order. Through this variable, you can completely customize and
+ control the appearance of an Ibuffer buffer. See also
+ `define-ibuffer-column', which allows you to define your own columns
+ for display.
+
+ This variable has the form
+ ((COLUMN COLUMN ...) (COLUMN COLUMN ...) ...)
+ Each element in `ibuffer-formats' should be a list containing COLUMN
+ specifiers. A COLUMN can be any of the following:
+
+ SYMBOL - A symbol naming the column. Predefined columns are:
+ mark modified read-only name size mode process filename
+ When you define your own columns using `define-ibuffer-column', just
+ use their name like the predefined columns here. This entry can
+ also be a function of two arguments, which should return a string.
+ The first argument is the buffer object, and the second is the mark
+ on that buffer.
+ or
+ \"STRING\" - A literal string to display.
+ or
+ (SYMBOL MIN-SIZE MAX-SIZE &optional ALIGN ELIDE) - SYMBOL is a
+ symbol naming the column, and MIN-SIZE and MAX-SIZE are integers (or
+ functions of no arguments returning an integer) which constrict the
+ size of a column. If MAX-SIZE is -1, there is no upper bound. The
+ default values are 0 and -1, respectively. If MIN-SIZE is negative,
+ use the end of the string. The optional element ALIGN describes the
+ alignment of the column; it can be :left, :center or :right. The
+ optional element ELIDE describes whether or not to elide the column
+ if it is too long; valid values are :elide and nil. The default is
+ nil (don't elide).
+
+ Some example of valid entries in `ibuffer-formats', with
+ description (also, feel free to try them out, and experiment with your
+ own!):
+
+ (mark \" \" name)
+ This format just displays the current mark (if any) and the name of
+ the buffer, separated by a space.
+ (mark modified read-only \" \" (name 16 16 :left) \" \" (size 6 -1 :right))
+ This format displays the current mark (if any), its modification and
+ read-only status, as well as the name of the buffer and its size. In
+ this format, the name is restricted to 16 characters (longer names
+ will be truncated, and shorter names will be padded with spaces), and
+ the name is also aligned to the left. The size of the buffer will
+ be padded with spaces up to a minimum of six characters, but there is
+ no upper limit on its size. The size will also be aligned to the
+ right.
+
+ Thus, if you wanted to use these two formats, add
+
+ (setq ibuffer-formats '((mark \" \" name)
+ (mark modified read-only
+ (name 16 16 :left) (size 6 -1 :right))))
+
+ to your ~/.emacs file.
+
+ Using \\[ibuffer-switch-format], you can rotate the display between
+ the specified formats in the list."

`apropos-mode', etc.

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