How do I re-wrap a paragraph to a certain line length?

Question

I have a big paragraph which I need to split into lines such that each line must not have more than 100 characters and no words must be broken. How would I go about doing this? I guess with regular expressions is the best way but I'm not sure how.

Answer 1

Use Text::Wrap.

Text::Wrap::wrap() is a very simple paragraph formatter. It formats a single paragraph at a time by breaking lines at word boundaries. Indentation is controlled for the first line ($initial_tab) and all subsequent lines ($subsequent_tab) independently.
