#backup installed extentions

The simplest way is to install the extention VScode Backup

step 1: know which extentions are installed by code --list-extensions

austin.code-gnu-global
CoenraadS.bracket-pair-colorizer-2
cschlosser.doxdocgen
hbenl.vscode-test-explorer
jeff-hykin.better-cpp-syntax
marus25.cortex-debug
matepek.vscode-catch2-test-adapter
ms-python.python
ms-python.vscode-pylance
ms-vscode.cpptools
ms-vscode.test-adapter-converter
RedVanWorkshop.explorer-exclude-vscode-extension
ruiquelhas.vscode-uppercase
streetsidesoftware.code-spell-checker
xaver.clang-format

step 2: install in new environment

code --install-extension xxxx

step 3: configuration

cd /home/$USER/.config/Code/User
tar -czf code-config.tar.gz *.json
mv code-config.tar.gz /home/$USER/code-backup

#using clang to format code

detail see https://www.dynamsoft.com/codepool/vscode-format-c-code-windows-linux.html

1. install clang format tool at llvm.org.

Actually, you don't need whole package, you only need the clang-format.exe.

2. install extention clang-format & configure

The example of configuration.

 

 The filename must be .clang-format. a method to make a file without filename. mv xx.clang-format .clang-format

 I would better put the .clang-format file at your project/workspace folder.

The .clang-format file can be generated by : clang-format.exe -style=llvm -dump-config > .clang-format

Note： brace at a new line 

BraceWrapping:
  AfterClass:      true
  AfterControlStatement: true
  AfterEnum:       true/false
  AfterFunction:   true
  AfterNamespace:  true/false
  AfterObjCDeclaration: true/false
  AfterStruct:     true/false
  AfterUnion:      true/false
  BeforeCatch:     true/false
  BeforeElse:      true/false
  IndentBraces:    true/false
BreakBeforeBraces: Custom

#Configuration files under .vscode folder

The code . command opens VS Code in the current working folder, which becomes your "workspace". As you go through the tutorial, you will create three files in a .vscode folder in the workspace:

• tasks.json (compiler build settings)
• launch.json (debugger settings)
• c_cpp_properties.json (compiler path and IntelliSense settings)

#config the include path

ctrl+shift+p ->c++ edit configuration (UI) or c++ edit configuration (JSON), the includePath, add the linux driver include path

    "configurations": [
        {
            "name": "Linux",
