🚨 CasePolice

• GitHub, not Github
• TypeScript, not Typescript
• macOS, not MacOS
• VS Code, not Vscode
• ...

Make the case correct, PLEASE!

Usage

Make sure you have committed all unsaved works, and then

npx case-police --fix

It will scan all your source files and fix the cases of known names.

Only the word including both uppercase and lowercase will be fixed. (e.g. Github -> GitHub; github and GITHUB will be left untouched).

Use in ESLint

We also provide an ESLint plugin that can be used to lint your codebase.

Flat Config

npm i -D eslint-plugin-case-police

// .eslint.config.js
import pluginCasePolice from "eslint-plugin-case-police";

export default [
  ...pluginCasePolice.configs.recommended,
];

OR

// .eslint.config.js
import pluginCasePolice from "eslint-plugin-case-police";

export default [
  {
    name: 'case-police',
    files: ['**/*.?([cm])[jt]s?(x)'],
    plugins: {
      'case-police': pluginCasePolice,
    },
    rules: {
      'case-police/string-check': 'warn',
    },
  },
]

Legacy Config

Since v2.0.0, we only support the flat config style. If you are using the legacy config, please use the version 1.x.x of the plugin.

npm i -D eslint-plugin-case-police@^1.0.0

// .eslintrc
{
  "extends": [
    "plugin:case-police/recommended"
  ]
}

Use in CI

Simply add case-police (without --fix) to your workflow and it will exit with a non-zero code for your CI to catch it.

Specific files

By default it will scan all the text files under the current directory (respects .gitignore), if you want it to check only specific files, you can pass the file paths of glob patterns to it.

npx case-police "**/*.md" path/to/file.html

CLI Options

Ignores

You can add @case-police-disable in your file to disable the case check for the particular file, or add @case-police-ignore xxx to ignore certain words in that file (use comma to separate mutliple words).

For example:

// @case-police-ignore Uri

console.log(something.Uri.path)
