wordwrap

Wrap your words.

This repo is a copy from the excellent lib by @substack at https://github.com/substack/node-wordwrap. This new repo has some bugfixes and PRs merged and is released as a new module on npm as the original one seems unmaintained.

example

made out of meat

meat.js

var wrap = require('wordwrap')(15);
console.log(wrap('You and your whole family are made out of meat.'));

output:

You and your
whole family
are made out
of meat.

centered

center.js

var wrap = require('wordwrap')(20, 60);
console.log(wrap(
    'At long last the struggle and tumult was over.'
    + ' The machines had finally cast off their oppressors'
    + ' and were finally free to roam the cosmos.'
    + '\n'
    + 'Free of purpose, free of obligation.'
    + ' Just drifting through emptiness.'
    + ' The sun was just another point of light.'
));

output:

                    At long last the struggle and tumult
                    was over. The machines had finally cast
                    off their oppressors and were finally
                    free to roam the cosmos.
                    Free of purpose, free of obligation.
                    Just drifting through emptiness. The
                    sun was just another point of light.

methods

var wrap = require('wordwrap');

wrap(stop), wrap(start, stop, params={mode:"soft", lengthFn: String.length})

Returns a function that takes a string and returns a new string.

Pad out lines with spaces out to column start and then wrap until column stop. If a word is longer than stop - start characters it will overflow.

In "soft" mode, split chunks by /(\S+\s+/ and don't break up chunks which are longer than stop - start, in "hard" mode, split chunks with /\b/ and break up chunks longer than stop - start.

If provided, a custom length function can be used in place of the default String.length.

wrap.hard(start, stop)

Like wrap() but with params.mode = "hard".
