Dired初窥
在EmacsManual目录下调出Dird后,
快速略扫各个文件的主要内容.
在目录上C-n和C-p上下移动光标.
** Dired操作:
1. Entering Dired: C-x d
2. Navigation: C-n C-p
3. Delete files: d, x, D
4. Flagging many files at once:
1) # (file start with #)
2) ~ (flag all backup files whose name end with ~)
3) % d regexp (delete all match regex)
5. Visiting Files
- f or e (visit current file)
- o (another window to display and switch fucus)
- C-o (visit but not switch focus)
- v (view-mode)
- ^ (dired-up)
6. Dired Marks vs. Flags
- * * excutable files
- * m mark
- * @ symbolic link
- * / directory
- * u remove the current
- U remove all
- % m regex
7. Operatons on files
- C copy
- D delete
- R rename
- H hardlink
- S symblic link
- Z, c
8. Shell Commands in Dired
- 这次阅读最大的收获, 可以直接 & 和 X
9. Transform files names
- % u Uppper-case
- % l lowercase
10. File comparision
- dired-diff
11. Subdirectory in Dired
- i
12. Subdirectories switch in Dired
-
13. Moving Over Subdirectories
-
14. Hiding Subdirectories
-
15. Updating the Dired Buffer
g
16. Dired and find
find-name-dired
17. Editing the dired Buffer
wdired
18. View Images thumbnails
image-dired-display-thumb

** Register操作归纳
M-x view-register r
# 以下所有的命令最后一个letter, 可以自定义为a-z等任何字母.
1. Saving Positions in Registers
C-x r r (register r)
# 可以自定义为 C-x r a (能记住便好)
C-x r j r (register jump to r)
2. Saving Text in Registers
C-x r s t (register save to r) "text"
# 修改为C-x r s t (t for text)
C-x r i t (regiester insert to r) "text"
M-x append-to-register t
M-x prepend-to-register t
3. Saving Rectangles in Registers
C-x r r e (rectangle region to e);
# 此处省略一个r, 完整语义(C-x r r r e)
# r been taken so use e for rectangle
register rectangle region to e
C-x r i e(rectangle insert to e )
4. Saving Window Configurations in Registers
C-x r w w (register window to w)
# 很好用的命令, 可以早上8点保存一个布局,晚上再看看, 临时记住的布局用winner-mode
C-x r f f (register frameset to f)
C-x r j f (jump)
5. Keeping Numbers in Registers
No practical value.
6. Keeping File Names in Registers
(set-register r '(file . name))
(set-register ?z '(file . "/gd/gnu/emacs/19.0/src/ChangeLog")
# prelude for bookmarks
7. Keyboard Macro Registers
--
8. Bookmarks
C-x r m (register bookmark for the current file)
C-x r m a-name
C-x r M (not overwrite)
C-x r b bookmark (jump or write)
C-x r l (list all bookmarks)
M-x bookmark-save
M-x bookmark-load filename
M-x bookmark-write filename
M-x bookmark-delete bookmark
M-x bookmark-insert-location bookmark
Additional
建议不要从零开始折腾Emacs,.
两步安装doom-emacs, 可以实现此项目内的所有操作.
假期结束，今天恢复更新。

在竞聘管理员, 差了20多票, 抽空给个支持.
此处提到两处弥足珍贵的键位绑定竟然空了出来， 没有被emacs作为绑定键使用。因而有机会将其自定义为”向上半屏翻页“和“向下半屏翻页”。
meta-n 调用 scroll-half-page-down, meta-p调用scroll-half-page-up。
然而，这个方法并不好用，尤其是快速浏览org笔记的时候，会被晃得晕头转向，还不如繁琐的M-r C-l C-l好用，因为焦点一直会停在中间。
而因为M-r C-l C-l 过于繁琐，出于本能，需要快速浏览的时候，就会只是快速的按键 C-n 不断地下一行。
作为解决方案，将
(scroll-up (/ (window-body-height) 2)))
修改为
(scroll-up (/ (window-body-height) 3)))
用了一段时间，尝试了不同的数值，三分很好用也符合直觉。速览的时候，M-n 然后 C-n再精确定位。
将函数名重新定义为 previous-multilines 与单行的previous-line保持一致。
(defun previous-multilines ()
"scroll down half the page"
(interactive)
(scroll-down (/ (window-body-height) 3)))
(defun next-multilines ()
"scroll up half the page"
(interactive)
(scroll-up (/ (window-body-height) 3)))
(global-set-key "\M-n" 'next-multilines) ;;custom
(global-set-key "\M-p" 'previous-multilines) ;;custom
关于进格删除（forward）与退格删除（backward）的语义化绑定。
退格删除则按键 backspace（Macbook上没有backspace键，可以将delete擦掉，改成backspace），backspace语义化对应backwords。
C-backspace 退格删除一个字符
M-backspace 退格删除一个word
进格删除的forward绑定到了字符 d（d for delete) 键上，
C-d 进格删除一个字符
M-d 进格删除一个word
C-k 进格删除到行尾
M-k 进格删除到句尾
C-x Backsapce 退格删除到行首
只有Backspace键是语义化的backword，其余都是forward。
最后，忘掉delete键，d 就是语义化的 delete。多余的delete键会引发逻辑上混乱。

这个编号有工具自动编号吗？还是自己手动编号的
手打的…
