Make the case correct, PLEASE!

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).

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

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',
    },
  },
]

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"
  ]
}

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

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

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)

actions-case-police. Use the correct letter case in GitHub issues and pull requests
