Conversions to String

sectionArgsToString :: [SectionArg ann] -> String Source #

Since: Cabal-3.6.0.0

fieldLinesToString :: [FieldLine ann] -> String Source #

Convert [FieldLine] into String.

Note: this doesn't preserve indentation or empty lines, as the annotations (e.g. positions) are ignored.

Since: Cabal-3.6.0.0
