In emacs, only half of a Chinese character is displayed:

Solution:Http://tikii.javaeye.com/blog/135007

 

As shown in the following figure, the words "no" and "wonderful" are both half displayed.

The answer was found at http://tikii.javaeye.com/blog/135007. the answer was originally the question of installing lingoes. Delete the font of lingoes installation. Specifically, delete the lingoes. ttf file in the c:/windows/fonts directory. Or find the installation directory of lingoes and delete all the font files listed in the following font sub-directories from C:/windows/fonts.

 

Settings of compilation commands in emacs:

From: http://suchang.net/slack/Emacs.html

Add the following code to. emacs:

1. ; C-f5, set the compile command, use the original compile of Emacs
2. ; F5: Save the current window and use different compilers for compilation. You can add a match as shown in the following code.
3. (Defun sucha-smart-compile ()
4. "Simply compile your file according to the file type ."
5. (Interactive)
6. (Save-some-buffers t)
7. (Let
8. (Compile-command nil)
9. (Alist
10. (List '("//. c $". "c:/mingw/bin/gcc ")
11. '("//. Cc $". "c:/mingw/bin/g ++ ")
12. '("//. Cpp $". "c:/mingw/bin/g ++ "))))
13. (While (not (null alist ))
14. (If (string-match (caar alist) (buffer-file-name ))
15. (Setq compile-command
16. (Concat (cdar alist) ""/"" (buffer-file-name )"/"")))
17. (Setq alist (cdr alist )))
19. (If (null compile-command)
20. (Setq compile-command
21. (Read-from-minibuffer "Compile command :")))
22. (Compile-command )))
23. (Global-set-key [C-f5] 'compile)
24. (Global-set-key [f5] 'sucha-smart-compile)

In the author's original article, lines 10, 11 and 12 are followed by: "gcc", "g ++", "g ++", c: /mingw/bin is the compiler path on your computer. In 16 lines of code, buffer-file-name is enclosed in double quotation marks to prevent spaces in the path.

 

Insert the current system time at the cursor:

1. ; Insert-current-time
2. (Defun insert-current-time ()
3. "Insert the current time"
4. (Interactive "*")
5. (Insert (current-time-string )))
6. (Global-set-key "/C-xt" 'insert-current-time)

 

Settings on the emacs startup window:

8. (Set-scroll-bar-mode nil)
9. ; Cancel the scroll bar
11. ; (Customize-set-variable 'scroll-bar-mode' right ))
12. ; Set the scroll bar to the right of the window, and the default is on the left
14. (Tool-bar-mode nil)
15. ; Cancel the toolbar
17. (Setq default-frame-alist
18. '(Vertical-scroll-bars)
19. (Top. 25)
20. (Left. 45)
21. (Width. 110)
22. (Height. 40)
23. (Background-color. "black ")
24. (Foreground-color. "gray ")
25. (Cursor-color. "gold1 ")
26. (Mouse-color. "gold1 ")
27. (Tool-bar-lines. 0)
28. (Menu-bar-lines. 1)
29. (Right-fringe)
30. (Left-fringe )))
33. ; Set other colors: the background and topic highlighted by the syntax, the background and topic selected by the region, and the background and topic selected by the secondary selection.
34. (Set-face-foreground 'highlight "white ")
35. (Set-face-background 'highlight "blue ")
36. (Set-face-foreground 'region "cyan ")
37. (Set-face-background 'region "blue ")
38. (Set-face-foreground 'secondary-selection "skyblue ")
39. (Set-face-background 'secondary-selection "darkblue ")
42. ;;;;;;;;;;;;;;;;;;;;;;;;;;;; Set the interface to end ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

You can modify the code in line 17--30 to automatically maximize the window at startup. Very convenient.

Copy the current row (that is, when we need to copy a row or cut a row, we do not need to select this row as region first, you only need to move the cursor to the current line and execute the normal copy and cut command)
