3. Use vscode

in the command line. If you are a Windows user, after installing and restarting the system, you You can use code or code-insiders in the command line. If you want to use it immediately instead of waiting for a restart, you can add the installation directory of VS Code to the system environment variable PATH

If you are a mac user, After installation, open the naming panel Cmd Shift P, search for the shell command, click to install the code command in the PAth, and then restart the terminal and it will be ok

The most basic use is to use the code command Open a file or folder

Note:

Before continuing to read the article, remember to remember the shortcut key to open the command panel Cmd shift P (Ctrl shift p under win)

一, Code editing

The shortcut keys under windows are placed in brackets

Cursor movement

Basics

Move to the beginning of the line Cmd left arrow key (win Home)

Move to the end of the line Cmd right arrow key (win End)

Move to the beginning and end of the document Cmd up and down Arrow keys (win Ctrl Home/End)

Jump between the left and right sides of the curly braces {}Cmd Shift (win Ctrl Shift)

Advanced

Return to the previous cursor position, Cmd U (win Ctrl U) is very useful. Sometimes in the vue file, if you change the html, you need to go to the bottom to change the js. After changing the js, you need to go back. At this time, Cmd U directly returns

Return to the previous cursor position between different files Control - (win has not been tested, I don’t know), you have changed file a, and after changing file b, you want to return to file a to continue editing, mac Use controls -

Text selection

You only need to press one more shift key to select the text while the cursor is moving

Select the word Cmd D The multi-cursor I will talk about below will also talk about Cmd D

There is no shortcut key for selecting code blocks. You can use cmd shift p to open the command panel and enter all the contents of the selection brackets. I will talk about how to add shortcut keys later

Delete

You can select the code and then delete it, then press Backpack (is it a backpack) or delete to delete, but that It’s too low to do

So, the geekiest way to delete is Cmd Shift K (win Ctrl Shift K). Delete as much as you want. Currently you can use ctrl x to cut, the effect is the same

Code movement

Option up and down arrow keys (win Alt up and down)

Code You can copy the code by holding down shift while moving. Option Shift up and down

Add comments

Comments come in two forms, single-line comments and block comments (in js, single-line comments //, block comments/ **/)

Single line comment Cmd / (win Ctrl /)

Block comment Option Shift A

Note: Different languages use different comments

2. Code format

Code formatting

Format the entire document: Option Shift F (win Alt Shift F), vscode will be based on For the language you use, use different plug-ins for formatting. Remember to download the corresponding formatting plug-in

to format the selected code: Cmd K Cmk F win(Ctrl K Ctrl F)

Code indentation

To adjust the indentation of the entire document, use Cmd Shift P to open the command panel, enter the indentation, and then select the corresponding command

Select the code indentation Indentation adjustment: Cmd ] Cmd [ respectively reduce and increase indentation (I don’t know under win, Baidu by yourself)

3. Some tips

Adjust characters Uppercase and lowercase, select it, and then enter in the command panel to convert to uppercase or to lowercase

Merge lines of code, multiple lines of code are merged into one line, Cmd J (not bound under win Define)

Line sorting, sort the code lines in alphabetical order, no shortcut keys, call up the command panel, enter to sort in ascending order or in descending order

4. Multi-cursor feature

Use the mouse:

Hold down Option (win Alt) , then use the mouse to click, and a cursor will appear wherever you click the mouse

Note: On some mac computers, you need to hold down Cmd and then click with the mouse

Shortcut Command

Cmd D (win Ctrl D) The first time you press it, it will select the word near the cursor; the second time you press it, it will Find the second occurrence of the word, create a new cursor, and select it. (Note: cmd-k cmd-d skips the current selection)

Option Shift i (win Alt Shift i) First you need to select multiple lines of code, and then press Option Shift i, the result of this is: there will be an extra cursor after each line

Undo multiple cursors

Use Esc to undo Multi-cursor

Click to undo

5. Quick jump (file, line, symbol)

Quickly open file

Cmd P (win Ctrl P) Enter the file name you want to open, press Enter to open

Enter Ctrl T under win to search and jump between symbols in different files

Definition and implementation

Cmd f12(win Ctrl f12) Jump to the implementation of the function

Reference jump

Many times, in addition to knowing the definition and implementation of a function or class, you may also want to know who they are referenced by and where they are referenced. At this time, you only need to move the cursor to the function or class, then press Shift F12, and VS Code will open a reference list and an embedded editor. In this reference list, if you select a reference, VS Code will display the code near the reference in the embedded editor.
