Synopsis

Documentation

data ParseError Source #

The abstract data type ParseError represents parse errors. It provides the source position (SourcePos) of the error and a list of error messages (Message). A ParseError can be returned by the function parse. ParseError is an instance of the Show and Eq classes.

errorPos :: ParseError -> SourcePos Source #

Extracts the source position from the parse error

data SourcePos Source #

The abstract data type SourcePos represents source positions. It contains the name of the source (i.e. file name), a line number and a column number. SourcePos is an instance of the Show, Eq and Ord class.

Instances

Eq SourcePos Source # 
Data SourcePos Source #
