condense-newlines

Replace extraneous newlines with a single newline, or pass a specified number of newlines to use.

Install

Install with npm:

$ npm install condense-newlines --save

var condense = require('condense-newlines');
console.log(condense('\n\na\n\n\nb\nc\r\n\r\nd\n\n\n'));
//=> '\na\nb\nc\nd\n';

Specify the separator to use

console.log(condense('\n\na\n\n\nb\nc\r\n\r\nd\n\n\n', {sep: '\n\n'}));
//=> '\n\na\n\nb\n\nc\n\nd\n\n';

The minimum number of consecutive newlines to condense.

console.log(condense('\n\na\n\n\nb\nc\r\n\r\nd\n\n\n', {min: 2}));
//=> '\n\na\n\nb\n\nc\n\nd\n\n';

Don't treat whitespace-only lines as newlines.

console.log(condense('\n\na\n\n      \nb\nc\r\n\r\nd\n\n\n', {
  keepWhitespace: true, sep: '\n\n'
}));

//=> '\n\na\n\n      \nb\n\nc\n\nd\n\n';
