Distribution.FieldGrammar

Description

This module provides a way to specify a grammar of .cabal -like files.

Synopsis

Field grammar type

class (c SpecVersion, c TestedWith, c SpecLicense, c Token, c Token', c FilePathNT) => FieldGrammar c g | g -> c where Source #

FieldGrammar is parametrised by

  • s which is a structure we are parsing. We need this to provide prettyprinter functionality
  • a type of the field.

Note: We'd like to have forall s. Applicative (f s) context.
