1. Download and store the clang-format.exe in a specific directory.
2. Copy .clang-format to the project directory.
3. Install extension Clang-Format in vscode and edit the config setting. 3.1 Run npm install clang-format -g to install clang-format in all platforms. the clang-path would be '${workspaceRoot}/node_modules/.bin/clang-format', in linux is: /usr/local/lib/node_modules/clang-format/bin/linux_x64/clang-format

{
    "clang-format.language.javascript.enable": false,
    "clang-format.executable": "C:\\clang-format.exe",
}

4. Use key Alt+shift+f to format the whole c/cpp file and use ctrl k + ctrl f to format the selected code block.
5. The format setting is detailed in .clang-format, which follows google's programing style and could be checked using cpplint.py.
6. A few rules are modified to make the format style more readable, and if you donn't want to format specific code, add the comment in your code.

// clang-format off
    void    unformatted_code  ;
// clang-format on
void formatted_code_again;

If some format result didn't pass the check of cpplint.py, adjust it yourself and add the comment above.

Here eslint is used in vscode by install extension ESLint and install the node module.

npm install eslint babel-eslint eslint-plugin-html -g

install globally may not work, better install every root dir of your project.

the config setting will be:

{
    "eslint.options": {
        "configFile": "C:/.eslintrc.js"
    },
    "editor.detectIndentation": false
}

ESLint is just a hint where you did not follow the style guide.
Format the js code could still use the key in vscode: Alt+shift+f or ctrl k + ctrl f .

EACCESS problem: ref

sudo chown -R $(whoami) /usr/local/lib/node_modules
