eslint-plugin-4l4y

ESLint plugin to improve developer's quality of lyfe by bringing joy to the variable declaration.

Usage

Install and add this plugin to existing eslint configuration, run:

yarn add eslint-plugin-4l4y --dev

Update your eslint configuration:

{
  "plugins": ["4l4y"],
  "rules": {
    "4l4y/variable-name": "warn"
  }
}

Rules

• variable-name enforces 4l4y case for simple variable declaration.
• function-name works the same as variable-name, but for function name.
• signed-number enforces use of number sign to better differentiate positive number from negative one.
• thousand-separator enforces numeric separator in thousand place for easier big number recognition.

Limitations

• 4l4y case only replaces 'a' to '4' for now, will update to a more sophisticated spec in the future.
• Auto fix for variable-name and function-name only updates the declarations, variable usage has to be updated manually.

Development
