Never Nest

I'm a never nester, and you should be too.

"... if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program."

-- Linus Torvalds

This extension makes it a little easier to avoid deep nesting, by highlighting your errors when you forget. It was inspired by Code Aesthetics' Never Nest Video, which I recommend watching if you're unfamiliar with the concept. Nesting too deep is a common anti-pattern in programming, that makes code less readable and harder to maintain.

👉 You can get here it in the VSCode Marketplace! 🛒

_{S/O to Code Aesthetics for the inspiration and Hans Raaf's indent rainbow extension for laying the groundwork.}

Extension Settings

This extension contributes the following settings:

• neverNest.includedLanguages: Languages for which never-nest should be activated. When empty will use for all languages.
• neverNest.colorLight: Color used to show nesting errors in light mode (hex, rgba, etc).
• neverNest.colorDark: Color used to show nesting errors in dark mode (hex, rgba, etc).
• neverNest.maxTabDepth: Maximum allowed nesting depth (consecutive tabs). Any more than this will count as a violation. Defaults to 3.
• neverNest.violationStyle: Style of violation highlighting. Can be either full or separator. Defaults to full.
  • full will highlight the entire line
  • separator will only highlight the tab indicator bars |.
• neverNest.enableHoverMessage: Whether to show a tooltip when hovering over the tab indicator. Defaults to false.

Known Issues

• The extension works best with consistent tabs or spaces. I recommend using editor.insertSpaces as true to avoid issues and having a consistent tab width.
