| 73 | ||
| 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 | |
| 79 | for display. | |
| 80 | ||
| 81 | This variable has the form | |
| 2e4fae7d | 82 | ((COLUMN COLUMN ...) (COLUMN COLUMN ...) ...) |
| 25d2f683 CW |
83 | Each element in `ibuffer-formats' should be a list containing COLUMN |
| 84 | specifiers. A COLUMN can be any of the following: | |
| 85 | ||
| 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 | |
| 92 | on that buffer. | |
| 93 | or | |
| 94 | \"STRING\" - A literal string to display. | |
| 95 | or | |
| 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 | |
| 105 | nil (don't elide). | |
| 106 | ||
| 107 | Some example of valid entries in `ibuffer-formats', with | |
| 108 | description (also, feel free to try them out, and experiment with your | |
| 109 | own!): | |
| 110 | ||
| 111 | (mark \" \" name) | |
| 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 | |
| 523304ed | 118 | will be truncated, and shorter names will be padded with spaces), and |
| 25d2f683 CW |
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 | |
| 122 | right. | |
| 123 | ||
| 124 | Thus, if you wanted to use these two formats, add | |
| 125 | ||
| 126 | (setq ibuffer-formats '((mark \" \" name) | |
| 127 | (mark modified read-only | |
| 128 | (name 16 16 :left) (size 6 -1 :right)))) | |

| 2162 | Information on Filtering: | |
| 2163 | ||
| 2164 | You can filter your ibuffer view via different critera. Each Ibuffer | |
| 2165 | buffer has its own stack of active filters. For example, suppose you | |
| 2166 | are working on an Emacs Lisp project. You can create an Ibuffer | |
| 2167 | buffer displays buffers in just `emacs-lisp' modes via | |
| 2168 | '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET'. In this case, there | |
| 2169 | is just one entry on the filtering stack. | |
| 2170 | ||
| 2171 | You can also combine filters. The various filtering commands push a | |
| 2172 | new filter onto the stack, and the filters combine to show just | |
| 2173 | buffers which satisfy ALL criteria on the stack. For example, suppose | |
| 2174 | you only want to see buffers in `emacs-lisp' mode, whose names begin | |
| 2175 | with \"gnus\". You can accomplish this via: | |
| 2176 | '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET | |
| 2177 | \\[ibuffer-filter-by-name] ^gnus RET'. | |
| 2178 | ||
| 2179 | Additionally, you can OR the top two filters together with | |
| 2180 | '\\[ibuffer-or-filters]'. To see all buffers in either | |
| 2181 | `emacs-lisp-mode' or `lisp-interaction-mode', type: | |
| 2182 | ||
| 2183 | '\\[ibuffer-filter-by-mode] emacs-lisp-mode RET \\[ibuffer-filter-by-mode] lisp-interaction-mode RET \\[ibuffer-or-filters]'. | |
| 2184 | ||
| 2185 | Filters can also be saved and restored using mnemonic names: see the | |
| 2186 | functions `ibuffer-save-filters' and `ibuffer-switch-to-saved-filters'. | |
| 2187 | ||
| 2188 | To remove the top filter on the stack, use '\\[ibuffer-pop-filter]', and | |
| 2189 | to disable all filtering currently in effect, use | |
| 2190 | '\\[ibuffer-filter-disable]'." | |
