disallow multiple empty lines (no-multiple-empty-lines)

Some developers prefer to have multiple blank lines removed, while others feel that it helps improve readability. Whitespace is useful for separating logical sections of code, but excess whitespace takes up more of the screen.

Rule Details

This rule aims to reduce the scrolling required when reading through your code. It will warn when the maximum amount of empty lines has been exceeded.

Options

This rule has an object option:

  • "max" (default: 2) enforces a maximum number of consecutive empty lines.
  • "maxEOF" enforces a maximum number of consecutive empty lines at the end of files.
  • "maxBOF" enforces a maximum number of consecutive empty lines at the beginning of files.
