Utilities

parsecQuoted :: CabalParsing m => m a -> m a Source #

Content isn't unquoted

parsecMaybeQuoted :: CabalParsing m => m a -> m a Source #

parsecMaybeQuoted p = parsecQuoted p | p.

parsecCommaList :: CabalParsing m => m a -> m [a] Source #

parsecLeadingCommaList :: CabalParsing m => m a -> m [a] Source #

Like parsecCommaList but accept leading or trailing comma.

p (comma p)*  -- p sepBy comma
(comma p)*    -- leading comma
(p comma)*    -- trailing comma

parsecLeadingCommaNonEmpty :: CabalParsing m => m a -> m (NonEmpty a) Source #

Since: Cabal-syntax-3.4.0.0

parsecLeadingOptCommaList :: CabalParsing m => m a -> m [a] Source #

Like parsecOptCommaList but

  • require all or none commas
  • accept leading or trailing comma.
p (comma p)*  -- p sepBy comma
(comma p)*    -- leading comma
(p comma)*    -- trailing comma
p*            -- no commas: many p
