some :: Alternative m => m a -> m (NonEmpty a)

some p applies the parser p one or more times and returns a list of the values returned by p.

word = some letter

endBy1 :: Alternative m => m a -> m sep -> m (NonEmpty a)

endBy1 p sep parses one or more occurrences of p, separated and ended by sep. Returns a non-empty list of values returned by p.

someTill :: Alternative m => m a -> m end -> m (NonEmpty a)

someTill p end works similarly to manyTill p end, but p should succeed at least once.

See also: skipSome, skipSomeTill.

sepBy1 :: Alternative m => m a -> m sep -> m (NonEmpty a)

sepBy1 p sep parses one or more occurrences of p, separated by sep. Returns a non-empty list of values returned by p.

sepEndBy1 :: Alternative m => m a -> m sep -> m (NonEmpty a)

sepEndBy1 p sep parses one or more occurrences of p, separated and optionally ended by sep. Returns a non-empty list of values returned by p.
