Readme for wryte-

[back to package description]


Pretty-printed source code with semi-automatic indentation


Wryte provides an API for generating textual source code with pretty indentation and alignment. To achieve this, it tracks source column position, newlines, and current indentation / alignment internally, and provides a monadic API to conveniently manage these.


The usual; cabal install wryte, or add wryte to your stack extra-dependencies.

Basic Usage

putStrLn . runWryte_ defWryteOptions $ do
  wryteLn "module Main where"
  wryteLn ""
  wryteLn "main = do"
  indented $ do
    wryteLn "putStrLn \"Hello, world!\"

Indentation is tracked monadically, such that indented acts as a wrapper that automatically prepends indentation to each new line. Indentations stack up, so you can safely nest them, and they will do the right thing.
