Dividing a String Across Lines

[twilit marten]

I have a string and I want to divide it into an array of strings that will be put on separate lines, where each string (or line) is not more than a given length. Each string should only be split on characters that normally allow line breaks, such as spaces.

For example, "Hello World" with a maxLength of 5 would be split into ["hello", "world"]. "Reference site about Lorem Ipsum" with a maxLength of 14 would be split into ["Reference site", "about Lorem", "Ipsum"].

Is there a built-in function to do this?

There is String#split

[twilit marten]

Doesn't that split on specific characters?

[icy rampart]

yes it does. You can use a regex pattern and it will split the provided string at each match

[twilit marten]

I only want it to split on line-breaking characters like spaces once it has exceeded the maximum line limit, though...

So
not
this

Is there a way to make String#split do that?

[icy rampart]

you can split the String using String#split and then append the substrings that are under your character limit. Alternatively use a for-loop.

Ok... I suppose I could just code it up myself, but if there's a built-in implementation, I can almost guarantee it'll be better than anything I write. Sounds like there isn't really one, though.

No that I am aware of.

[twilit marten]

Ok.
