[英]reformat 'File' field in emacs buffer list?
Context: using the Buffer List in Emacs to see what I'm doing, choose a buffer to visit, etc. FYI, I use fairly deep (sub-)directory organization to organize my files. 上下文:使用Emacs中的“ 缓冲区列表”来查看我在做什么,选择要访问的缓冲区等。仅供参考,我使用相当深的(子)目录组织来组织我的文件。
When I have lots of files open from the same subdirectory, the 'File' field mostly shows the part of the pathname that is the same for all files, ie the first 2-3 layers in my hierarchy of directories. 当我从同一子目录中打开大量文件时,“文件”字段通常显示路径名中与所有文件相同的部分,即目录层次结构中的前2-3层。 So it gives me high-level info that's not very useful. 因此,它给我提供的高级信息不是很有用。 The 'Buffer' field shows me the filename. “缓冲区”字段显示了文件名。 That gives me low-level info that's too specific. 这给了我太具体的低层信息。
Is there a way to reformat the 'File' field to show me the most useful part of the file's path, ie the last couple of sub-directories the file is contained in and the filename? 有没有一种方法可以重新格式化“文件”字段,以向我显示文件路径中最有用的部分,即文件所包含的最后两个子目录以及文件名? Literally, maybe the last characters of the path, instead of the first ? 从字面上看,也许是路径的最后一个字符,而不是第一个?
I prefer ibuffer for this sort of thing over buffer-menu. 我喜欢ibuffer而不是buffer-menu。 It allows you to group the file names by their name. 它允许您按文件名对文件名进行分组。
For instance, I have this in my .emacs (stolen from emacs-fu for the most part). 例如,我的.emacs文件中有此文件(大多数情况下是从emacs-fu中窃取的)。
(require 'ibuffer)
(setq ibuffer-saved-filter-groups
(quote (("default"
("MyProject"
(filename . "/path/to/my/project/"))
("Programming"
(or
(mode . sh-mode)
(mode . c-mode)
(mode . cperl-mode)
(mode . python-mode)
(mode . emacs-lisp-mode)
;; etc
))
("Org" ;; all org-related buffers
(mode . org-mode))
("ERC"
(mode . erc-mode))
("Jabber"
(or ;; jabber-related buffers
(mode . jabber-chat-mode)
(mode . jabber-mode)
(mode . jabber-roster-mode)
;; etc.; all your mail related modes
))))))
(add-hook 'ibuffer-mode-hook
(lambda ()
(ibuffer-switch-to-saved-filter-groups "default")))
(global-set-key (kbd "C-x C-b") 'ibuffer)
This might also help, though it does not address your question directly: Buffer Menu+ . 尽管它不能直接解决您的问题: Buffer Menu + ,但这也可能有帮助。
You can use + and - to resize the Buffer
and Size
columns, giving more space to the other columns. 您可以使用+和-来调整Buffer
和Size
列的Size
,为其他列留出更多空间。
You can toggle the display of columns Time
and Mode
, to give other columns more space. 您可以切换Time
和Mode
列的显示,以给其他列更多的空间。 (You can also toggle the Time
format, making it shorter without removing it.) (您还可以切换Time
格式,使其更短而不删除。)
