breakword v1.0.5

Get index of character after which variable 'word' must be broken given variable 'length' (accounts for wide characters).

breakword

Get index i.e. 0,1,2,... of the character where a word must be broken given it must be wrapped within a certain length of spaces.

Useful because javascript's String.length does not reflect the true width of emojis and wide characters.

Installation

npm install breakword 

Examples

  1. To find the index of the character to break after if we want to limit our characters fit on a line 3 spaces wide.
var Breakword = require ("breakword");
var word = "打破我的角色三";
var breakIndex = Breakword(word,3); 
console.log(breakIndex) //0

The result here - 0 - means all the characters before index 0 (in this case only the character 打) can fit in a line 3 spaces long.
