Manilla

Go from this:

Hello, world!

to this:

Manilla.fold('Hello, world!', 8, "\r\n\s", :word)
# => Hello,
#     world!

and back again:

Manilla.unfold("Hello,\r\n world!", "\r\n\s")
# => Hello, world!

Add this line to your application's Gemfile:

gem 'manilla'

And then execute:

$ bundle

Or install it yourself as:

$ gem install manilla

Manilla provides two methods for folding text: character and word

Folding on character will instruct Manilla to insert a fold at a specific width. It will not pay attention to word boundaries or any other delimiter. Character folding is the default folding method.

Manilla.fold('Hello, world!', 8, "\r\n\s")
# => Hello, w
#     orld!

Word folding will cause Manilla to break text at word boundaries.

Manilla.fold('Hello, world!', 8, "\r\n\s", :word)
# => Hello,
#     world!

If a word is longer than the specified max width it will be folded at max width.

Manilla.fold('Hello, world!', 2, "\r\n\s", :word)
# => He
#     ll
#     o,
#
#     wo
#     rl
#     d!

Unfolding is the process of reversing a fold. It will treat delimiters as blank strings.

folded_text = Manilla.fold('Hello, world!', 8, "\r\n\s", :word)

Manilla.unfold(folded_text, "\r\n\s")
# => Hello, world!

Fold text using the specified delimiter at a maximum width. Folding can occur on :char or :word.

Unfold text using a specified delimiter.
