module Manilla

Breaks long lines of text into multiple delimited representations.

@example Fold text on character

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

@example Fold text on word

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

@param text [String] The text to be folded @param maxwidth [Integer] The maximum length of a line of text @param delimiter [String] String used to denote line boundaries @param break_on [Symbol] Specifies whether to fold text on a character

(`:char`) or word (`:word`) (default: `:char`)

# File lib/manilla.rb, line 26
def self.fold(text, maxwidth, delimiter, break_on = :char)
  Manilla::Folder.call(text, maxwidth, delimiter, break_on)
end

Moves from a folded delimited representation to a single line representation by treating delimiters as blank strings.

@example Unfold text

text = "Hello, world!"

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

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

@param text [String] Text to be unfolded @param delimiter [String] String used to denote line boundaries

# File lib/manilla.rb, line 47
def self.unfold(text, delimiter)
  Manilla::Unfolder.call(text, delimiter)
end
