GNU Info (gnus)Tree DisplayTree Display ============ If you don't like the normal Gnus summary display, you might try setting `gnus-use-trees' to `t'. This will create (by default) an additional "tree buffer". You can execute all summary mode commands in the tree buffer. There are a few variables to customize the tree display, of course: `gnus-tree-mode-hook' A hook called in all tree mode buffers. `gnus-tree-mode-line-format' A format string for the mode bar in the tree mode buffers (Note: Mode Line Formatting). The default is `Gnus: %%b %S %Z'. For a list of valid specs, Note: Summary Buffer Mode Line. `gnus-selected-tree-face' Face used for highlighting the selected article in the tree buffer. The default is `modeline'. `gnus-tree-line-format' A format string for the tree nodes. The name is a bit of a misnomer, though--it doesn't define a line, but just the node. The default value is `%(%[%3,3n%]%)', which displays the first three characters of the name of the poster. It is vital that all nodes are of the same length, so you _must_ use `%4,4n'-like specifiers. Valid specs are: `n' The name of the poster. `f' The `From' header. `N' The number of the article. `[' The opening bracket. `]' The closing bracket. `s' The subject. Note: Formatting Variables. Variables related to the display are: `gnus-tree-brackets' This is used for differentiating between "real" articles and "sparse" articles. The format is `((REAL-OPEN . REAL-CLOSE) (SPARSE-OPEN . SPARSE-CLOSE) (DUMMY-OPEN . DUMMY-CLOSE))', and the default is `((?[ . ?]) (?( . ?)) (?{ . ?}) (?< . ?>))'. `gnus-tree-parent-child-edges' This is a list that contains the characters used for connecting parent nodes to their children. The default is `(?- ?\\ ?|)'. `gnus-tree-minimize-window' If this variable is non-`nil', Gnus will try to keep the tree buffer as small as possible to allow more room for the other Gnus windows. If this variable is a number, the tree buffer will never be higher than that number. The default is `t'. Note that if you have several windows displayed side-by-side in a frame and the tree buffer is one of these, minimizing the tree window will also resize all other windows displayed next to it. `gnus-generate-tree-function' The function that actually generates the thread tree. Two predefined functions are available: `gnus-generate-horizontal-tree' and `gnus-generate-vertical-tree' (which is the default). Here's an example from a horizontal tree buffer: {***}-(***)-[odd]-[Gun] | \[Jan] | \[odd]-[Eri] | \(***)-[Eri] | \[odd]-[Paa] \[Bjo] \[Gun] \[Gun]-[Jor] Here's the same thread displayed in a vertical tree buffer: {***} |--------------------------\-----\-----\ (***) [Bjo] [Gun] [Gun] |--\-----\-----\ | [odd] [Jan] [odd] (***) [Jor] | | |--\ [Gun] [Eri] [Eri] [odd] | [Paa] If you're using horizontal trees, it might be nice to display the trees side-by-side with the summary buffer. You could add something like the following to your `.gnus.el' file: (setq gnus-use-trees t gnus-generate-tree-function 'gnus-generate-horizontal-tree gnus-tree-minimize-window nil) (gnus-add-configuration '(article (vertical 1.0 (horizontal 0.25 (summary 0.75 point) (tree 1.0)) (article 1.0)))) Note: Windows Configuration. |
