Description

Cabal-like file AST types: Field, Section etc,

This (intermediate) data type is used for pretty-printing.

Since: Cabal-3.0.0.0

showFields :: (ann -> [String]) -> [PrettyField ann] -> String Source #

Prettyprint a list of fields.

Note: the first argument should return Strings without newlines and properly prefixes (with --) to count as comments. This unsafety is left in place so one could generate empty lines between comment lines.

showFields' :: (ann -> [String]) -> Int -> [PrettyField ann] -> String Source #

showFields with user specified indentation.

Transformation from `Field`

fromParsecFields :: [Field ann] -> [PrettyField ann] Source #
