Powershell - 拆分字符串

Question

我正试图在power-shell中分割一个字符串...我已经对字符串做了一些工作,但我无法弄清楚这最后一部分.

说我坐在这个字符串:

This is a string. Its a comment that's anywhere from 5 to 250 characters wide.

我想把它拆分为30个字符,但我不想分开一个单词.如果我要将它分开,它会在一行上有"...... commen"......下一行就是"那个......".

什么是优雅的方式来分割字符串,50max,而不会破坏一个字？为简单起见,一个单词就是一个空格(注释中也可能有数字文本"$ 1.00".也不想将其分成两半).

Answer 1

$regex = [regex] "\b"
$str = "This is a string. Its a comment that's anywhere from 5 to 250 characters wide."
$split = $regex.split($str, 2, 30)
