Code Formating

How to do code formating?

.cpp/.h/.ino files of src directory

The code must be formatted using the clang-format tool. The configuration style is Google, no other extra customization is necessary. The tool can be added as extension in vscode, and will format one active file at once per request or during saving process according your vscode settings.

A python script is also available in the repository, in directory tools: format_sources.py, this script can be used to format all files of the directory src, and all subdirectories at once.

.js/.css files of embedded directory

The code must be formatted using the prettier tool. The configuration style is .prettierrc present in the root of embedded directory. The configuration file is as follows:

{
  "printWidth": 80,
  "tabWidth": 4,
  "useTabs": false,
  "semi": true,
  "singleQuote": false,
  "trailingComma": "es5",
  "bracketSpacing": true,
  "bracketSameLine": false,
  "arrowParens": "always",
  "requirePragma": false,
  "insertPragma": false,
  "proseWrap": "preserve",
  "overrides": [
    {
      "files": "*.js",
      "options": {
        "parser": "babel"
      }
    },
    {"files": "*.scss",
      "options": {
        "parser": "css"
      }
    }
  ]
}

The tool can be added as extension in vscode, and installed using :

npx install -G prettier

A python script is also available in the repository, in directory embedded/tools: format_sources.py, this script can be used to format all files of the directories embedded/config and embedded/src, and all subdirectories at once.

When to do code formating?

Before any pull request or before submit any code, the code must be formatted. The CI will check the code formatting, and will eventually fail if the code is not formatted correctly.
