Vim Chinese tutor

Vim Chinese tutor

Vim is a powerful editor with many commands. This document will not be detailed in this tutorial. The purpose of this tutorial is to describe some necessary basic commands. With these commands, you can easily use Vim as a universal editor.

It takes about 25-30 minutes to complete this tutorial, depending on your training time.

The command operations in each section will change this article. We recommend that you copy a copy of this article and then perform training on the copy (if you start the tutorial through "vimtutor", this article is already a copy ).

Remember: the design concept of this tutorial is learned during use. That is to say, You need to execute commands to learn their correct usage. If you only read these commands without performing any operations, you may soon forget these commands!

Now, please make sure that your shift-lock (case-insensitive key) has not been pressed, and then press the keys J on the keyboard enough times to move the cursor, until the content in section 1 is fully filled with the screen.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Lecture 1 Section 1: move the cursor

※To move the cursor, press the H, J, K, and l keys respectively. ※※

^
K indicates that the key of H is on the left, and is moved to the left every time you press it.
<H L> L's key is on the right. Each press will move to the right.
The J key looks like a downward arrow at the tip.
V

1. move the cursor freely on the screen until you feel comfortable.

2. Press the downstream key (j) until the cursor repeats.

-> Now you have learned how to move to the next lecture.

3. now use the downstream key to move the cursor to lecture 2.

Tip: If you are not sure about the letter you press, press <ESC> to return to normal mode. Enter the command you want on the keyboard again.

Tip: The cursor key should work properly. However, with the hjkl key, you can move the cursor around the screen quickly.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Section 3 and section 4: Other change-type commands using the C command

** You can change the object parameters used by class commands by using the same Delete class commands. **

1. Changing the operating method of class commands is the same as deleting class commands. The operation format is:

[Number] C object or C [number] Object

2. The same is true for object parameters. For example, W represents a single word/Word, and $ represents the end of a row.

2. To replace the characters at the cursor position, enter the lower-case character R and the new character to replace the original character.

3. The change class command allows you to change the specified object from the current cursor position to the end of the object. For example, input CW can replace the content from the current cursor to the end of the word; input C $ can replace the content from the current cursor to the end of the line.

4. Change the class command format:

[Number] C object or C [number] Object

Next, let's continue with our next lecture.

Section 4 Section 1: positioning and file status

** Enter Ctrl-g to display the row position and file status information of the current cursor in the current editing file.
Enter the SHIFT-G to jump directly to a specified line in the file. **

Tip: you must read the content of this section before performing the following steps !!!

1. Press ctrl and press G. Then, a status information line is displayed at the bottom of the page, showing the currently edited file name and the total number of lines of the file. Remember the row number in step 3.

2. Press the SHIFT-G key to make the current cursor jump directly to the last line of the file.

3. Enter the row number you have stayed in, and then press shift-G. In this way, you can return the row where you pressed Ctrl-g for the first time. Note: When you enter a row number, the row number is not displayed on the screen.

4. If you want to, continue with steps 1 to 3.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Section 4 Section 2: search commands

** The input/and trailing strings can be used to search for the string in the current file. **

1. Enter/character in normal mode. You will notice that the character and the optical mark will appear at the bottom of the screen, which is the same as the command.

2. Enter errroor <press enter>. The errroor is the string you want to search.

3. To search for the same string as the previous one, you only need to press the n key. To search for the same string in the opposite direction, Enter Shift-n.

4. If you want to reverse query a string, use? Replace.

-> When the search reaches the end of the file it will continue at
Start.

"Errroor" is not the way to spell error; errroor is an error.

Tip: if the search has reached the end of the file, the search will automatically continue from the file header.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Section 4: Search for pair brackets

** Matching parentheses can be searched by %),], and}. **

1. Place the cursor below this section to mark any of the rows (, [, or.

2. Press % characters.

3. The position of the time mark should be in the matching brackets.

4. Press % again to jump back to the first bracket of the pair.

-> This (is a test line with ('s, ['s] And {'s} in it .))

Tip: During program debugging, this function is useful for finding unpaired parentheses.

3. Input: S/thee/The/g to replace the matching string of the entire row.

-> The best time to see thee flowers is in thee spring.

4. To replace each matching string between two rows, enter #, # S/old/new/g (#, # stands for the row number of the two rows ). Enter % S/old/new/g to replace each matching string in the entire file.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Conclusion 4

1. CTRL-G is used to display the current cursor position and file status information. Shift-G is used to jump the cursor to the last line of the file. First, knock in a row number and then press shift-g to move the cursor to the row represented by this row number.

2. Input/followed by a string, which is to be searched backward in the document currently edited. Enter question mark? Followed by a string, the string is searched forward in the document being edited. After a search is completed, press the n key to repeat the previous command. You can find the next string in the same direction, or press shift-N to find the string in the opposite direction.

3. If the current cursor position is parentheses (,), [,], {,}, you can move the cursor to the matching brackets by %.

4. Replace the header string old with the new string new in a row. Enter "s/old/new ".
Replace all the strings old with the new string new in one line. Enter: S/old/new/g.
Replace all the strings old with the new string new in the two rows. Enter: #, # S/old/new/g.
Replace all the strings old with the new string new in the file. Enter % S/old/new/g.
During full-text replacement, ask the user to confirm that C option is required for each replacement. Enter % S/old/new/GC.

Section 5 Section 1: how to execute External commands in VIM

** Input :! Then, enter an external command to execute the command. **

1. Press what we are familiar with: the command sets the cursor to the bottom of the screen. In this way, you can enter the command.

2. Enter an exclamation point! This character allows you to execute external shell commands.

3. Take the LS command as an example. Enter! Ls <press enter>. This command will list the contents of your current directory, just as the result of entering the LS command at the command line prompt. If! Ls does not work. You can try :! Dir.

-> Note: all external commands can be executed in this way.

-> Tip: All commands must end with <press enter>.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Section 5 section II: more information on saving files

** To save changes to the file, enter W filename. **

1. Enter :! DIR or :! Ls obtains the content of the current directory. You should have known that you have to press <enter>.

2. Select a file name that does not exist, such as test.

3. Enter W test (here test is the selected file name .)

4. This command saves the entire file with the file name test (Vim tutorial ). To ensure correct saving, enter again :! Dir to view the contents of your directory list.

-> Note: If you exit vim and enter the file with the file name test as the parameter, the file content should be exactly the same as the file content you saved.

5. Now you can enter :! Rm test to delete the test file.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Section 5: a selective saving command

** To save part of the file, enter: #, # W filename **

1. Run it again :! DIR or :! Ls gets the content of the current directory, and then selects a suitable file name without duplicate names, such as test.

2. move the cursor to the top of the page, and press Ctrl-g to find the row number. Don't forget the row number.

3. move the cursor to the bottom of the page and press Ctrl-G again. Don't forget the row number.

4. To save only a part of the article, enter: #, # W test. Here, #, # Is the row number (the top row number and the bottom row number) that you need to remember, and test is the selected file name.

5. Finally, use :! Dir: Check whether the file is correctly saved. But do not delete it this time.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Section 5: extracting and merging files

** To insert the content of another file into the current file, enter R filename **

1. Enter :! Dir confirm that the test file you created earlier is still in.

2. move the cursor to the top of the current page.

Note: After step 3 is executed, you will see section 3 of lecture 5. Please move it back here.

3. Use R test to extract the file named test.

Note: The extracted file will be placed at the position of the cursor.

4. to confirm that the file has been extracted successfully, move the cursor back to the original position. Note that there are two copies in section 3 of the fifth lecture, one is the original and the other is a copy from the file.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Summary

1 .:! Command is used to execute an external command.

See some examples:
:! Dir-displays the content of the current directory.
:! Rm filename-used to delete a file named filename.

2.: W filename can save the file being edited in VIM to the file named filename.

3.: #, # W filename can save the content of row # To row # Of the current edited file to the file filename.

4.: R filename extracts the disk file filename and inserts it behind the cursor position of the current file.

2. Enter lowercase A to insert text after the cursor. In upper case, a can insert text directly at the end of the row.

Tip: you can insert text at the end of a line by inputting uppercase A to avoid entering I. move the cursor to the last character and enter the text. <ESC> return to normal mode, right-click the arrow to move the cursor and X to delete the characters at which the current cursor is located.

3. You can complete the first line after the operation. Note that the insert text behind the cursor is basically the same as the insert mode, but the position of the insert text is slightly different.

-> This line will allow you to practice
-> This line will allow you to practice appending text to the end of a line.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Section 6: Section 3: version of another replacement command

** You can enter uppercase letters to replace multiple consecutive characters in R. **
