cc

Code style linter for C++ source files used in Node.js native addons.

Follows the Google C++ Style Guide.

As standard, semistandard and xo are to your JavaScript source files, cc is to your C++ source files.

Using from the command line

npx cc

Adding to a native module as a development dependency

npm install cc --save-dev

Add cpplint to the test script of your project's package.json file.

The following example uses xo for linting JavaScript, cpplint for linting C++ and ava for unit tests.

{
  "name": "awesome-native-package",
  "scripts": {
    "test": "xo && cpplint && ava"
  },
  "devDependencies": {
    "ava": "^2.4.0",
    "cc": "^3.0.0",
    "xo": "^0.25.3"
  }
}

Defaults

"cc": {
  "linelength": "80",
  "files": [
    "**/*.cc",
    "**/*.h"
  ],
  "ignore": [
    "node_modules/**",
    "vendor/**"
  ],
  "filter": []
}

Files listed in .gitignore or contained within any "dot" directories (e.g. .git) are also ignored.

Example

Allow a line length of 120 characters and ignore all include checks:

{
  "name": "awesome-native-package",
  "scripts": {
    "test": "cpplint"
  },
  "devDependencies": {
    "cc": "^3.0.0"
  },
  "cc": {
    "linelength": "120",
    "filter": [
      "build/include"
    ]
  }
}

Thanks
