Pretty-print a value

This module contains logic for pretty-printing expressions, including support for syntax highlighting

Pretty-print a FileMode. The format is similar to the one ls(1): It is display as three blocks of three characters. The first block are the permissions of the user, the second one are the ones of the group and the third one the ones of other subjects. A r denotes that the file or directory is readable by the subject, a w denotes that it is writable and an x denotes that it is executable. Unset permissions are represented by -.

Pretty-print an Expr using the given CharacterSet. prettyCharacterSet largely ignores Notes. Notes do however matter for the layout of let-blocks:

>>> let inner = Let (Binding Nothing "x" Nothing Nothing Nothing (NaturalLit 1)) (Var (V "x" 0)) :: Expr Src ()

>>> prettyCharacterSet ASCII (Let (Binding Nothing "y" Nothing Nothing Nothing (NaturalLit 2)) inner)
let y = 2 let x = 1 in x

>>> prettyCharacterSet ASCII (Let (Binding Nothing "y" Nothing Nothing Nothing (NaturalLit 2)) (Note (Src unusedSourcePos unusedSourcePos "") inner))
let y = 2 in let x = 1 in x

This means the structure of parsed let-blocks is preserved.

Wrapper around HttpExceptions with a prettier Show instance In order to keep the library API constant even when the with-http Cabal flag is disabled the pretty error message is pre-rendered and the real HttpException is stored in a Dynamic
