doclayout

CItests

This is a prettyprinting library designed for laying out plain-text documents. It originated in the pandoc module Text.Pandoc.Pretty, and its development has been guided by pandoc's needs in rendering wrapped textual documents.

In supports wrapping of text on breaking spaces, indentation and other line prefixes, blank lines, and tabular content.

Example:

Text.DocLayout> mydoc = hang 2 "- " (text "foo" <+> text "bar")
Text.DocLayout> putStrLn $ render (Just 20) mydoc
- foo bar
Text.DocLayout> putStrLn $ render (Just 10) (prefixed "> " (mydoc $+$ mydoc))
> - foo
>   bar
>
> - foo
>   bar

The Doc type may be parameterized to either String or (strict or lazy) Text, depending on the desired render target.
