It's been a while that my pull request is on pending status, actually I need this feature on my project. It would be great if it can be merged this week.

[bezoerb]

@arnaud-zg: sorry for taking so long to come back. This implementation may compute wrong values as the browser would not break the words like this (won't add - at the end) I think it's important that the result reflects the behavior from the browser. Did you know that you can use the word-break: 'break-all' css rule (either in css or overwrite in your call)

 textMetrics(el).lines(text, {}, {'word-break': 'break-all'})
/*
[ 'Craspharetraph',
  'aretragravida.Vi',
  'vamusconsequ',
  'atlacusvelposu',
  'erecongue.Duis',
  'aloremvitaeexa',
  'uctorscelerisqu',
  'enoneuturpis.Ut',
  'imperdietmagn',
  'asitametjustobi',
  'bendumvehicul',
  'a.' ]
*/

Browser:

Sorry to not mention this before. Does this help with your project or do you depend on text-metrics adding the ­ to each line? You should also keep in mind, that adding the separator will result in grammatical errors

[arnaud-zg]

According to word-break and hyphens documentation, I updated my code and added those two option. Case 1

textMetrics(el).lines(text, {}, {wordBreak: 'break-all'})
/*
[ 'Craspharetraph',
  'aretragravida.Vi',
  'vamusconsequ',
  'atlacusvelposu',
  'erecongue.Duis',
  'aloremvitaeexa',
  'uctorscelerisqu',
  'enoneuturpis.Ut',
  'imperdietmagn',
  'asitametjustobi',
  'bendumvehicul',
  'a.' ]
*/

Case 2

textMetrics(el).lines(text, {}, {hyphens: 'auto'})
/*
[ 'Craspharetraph-',
  'aretragravida.Vi-',
  'vamusconsequ-',
  'atlacusvelposu-',
  'erecongue.Duis-',
  'aloremvitaeexa-',
  'uctorscelerisqu-',
  'enoneuturpis.Ut-',
  'imperdietmagn-',
  'asitametjustobi-',
  'bendumvehicul-',
  'a.' ]
*/

Up

[bezoerb]

Sorry @arnaud-zg, i don't think it's a good idea to add this feature as this won't match the expected behavior. When doing auto hyphens this should be done properly with grammatical correct results.
