data ParseError a

Constructors

LexicalError (NonEmpty SourcePos) (Maybe (ErrorItem Char)) (Set (ErrorItem Char))

An error occured during tokenization (this is a re-packed megaparsec error)

ParseError (NonEmpty SourcePos) (Maybe (ErrorItem (PyToken a))) (Set (ErrorItem (PyToken a)))

An error occured during parsing (this is a re-packed megaparsec error)

TabError a

Tabs and spaces were used inconsistently

IncorrectDedent a

The dedent at the end of a block doesn't match and preceding indents

e.g.

def a():
    if b:
        pass
    else:
        pass
  pass

The final line will cause an IncorrectDedent error

InvalidUnpacking a

Unpacking ( *value ) was used in an invalid position
