ellipsize

ellipsize

Ellipsizes a string near a word boundary.

An ellipsized text looks much better if the ellipsize was added at the end of the last full word instead of somewhere in the middle - especially if there are very few characters remaining.

N.B. Major version change

As of 1.x, ellipsize honors the max length including the ellipsize char. This means you get exactly n characters, including the ellipse.

Why make a module for something sooo simple

Off by one errors.

I've written a couple of ellipsize functions, and got it wrong on edge cases several times. It's not rocket science, but something as simple as this you should write in five minutes right? Never mind the unit test.

This ellipsize function is robust and tested against a couple of edge cases. It's written to be fast, work in any browser and have no dependencies at all.

It simply loops over all the characters using a single function call, storing the last location of an allowed break point, if any. Otherwise it just truncates the string or return empty string if truncate options set up to false (in some cases its just better).

Examples

    var ellipsize = require('ellipsize');

    ellipsize('');
    // ''
    ellipsize(undefined);
    // ''
    ellipsize('one two three four', 8 );
    // 'one two…'
    ellipsize('one two-three four', 8 );
    // 'one two…'
    ellipsize('one two three four', 100 );
    // 'one two three four'
    ellipsize('12345678910')
    // '1234567…'
    ellipsize('abc', 0 );
    // ''

You may provide an alternative ellipse character, or "break points" like so:

    var ellipsize = require('ellipsize');

    ellipsize( 'one two&three four', 8, { chars: [' ', '&'], ellipse: '→' });
    // 'one two→'

Also you may provide a setting to truncate words:

    var ellipsize = require('ellipsize');

    ellipsize( '123456789ABCDEF', 8, { truncate: false });
    // '' 

    // its default settings
    ellipsize( '123456789ABCDEF', 8, { truncate: true });
    // '1234567…'
