Textwrap

Textwrap is a set of NIF bindings to the textwrap Rust crate, for wrapping, indenting, and dedenting text.

Installation

This package is available in Hex, and can be installed by adding textwrap to your list of dependencies in mix.exs:

def deps do
  [
    {:textwrap, "~> 0.1.0"}
  ]
end

Getting Started

Use fill/2 to get a wrapped string, or wrap/2 to get a list of wrapped lines:

iex> Textwrap.fill("Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor", 30)
"Lorem ipsum dolor sit amet,\nconsectetur adipisicing elit,\nsed do eiusmod tempor"

iex> Textwrap.wrap("Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor", 30)
["Lorem ipsum dolor sit amet,", "consectetur adipisicing elit,", "sed do eiusmod tempor"]

The second argument to fill/2 or wrap/2 can instead be a keyword list with the desired width as well as further options:

iex> Textwrap.wrap("Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor", width: 30, initial_indent: "> ", subsequent_indent: ">> ")
["> Lorem ipsum dolor sit amet,", ">> consectetur adipisicing", ">> elit, sed do eiusmod tempor"]

The width can either be a positive integer, or :termwidth. In the latter case, the width of the terminal connected to standard output is used, or a fallback width of 80 otherwise.

See the API docs for more details.
