var wrap = require('wordwrap');
|

|
|
|

|
wrap(stop), wrap(start, stop, params={mode:"soft"})

---------------------------------------------------
|
||
|
|
|
||
|
|
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`.
|
||
|
|
|
||
|
|
wrap.hard(start, stop)
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
Like `wrap()` but with `params.mode = "hard"`.
