data ParseError

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 Text.Parsec.Prim.parse. ParseError is an instance of the Show class. Instances Show ParseError

errorPos :: ParseError -> SourcePos

Extracts the source position from the parse error

data SourcePos

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 Ord SourcePos Show SourcePos

type SourceName = String

type Line = Int

type Column = Int

sourceName :: SourcePos -> SourceName

Extracts the name of the source from a source position.

sourceLine :: SourcePos -> Line

Extracts the line number from a source position.

sourceColumn :: SourcePos -> Column

Extracts the column number from a source position.

incSourceLine :: SourcePos -> Line -> SourcePos

Increments the line number of a source position.

incSourceColumn :: SourcePos -> Column -> SourcePos

Increments the column number of a source position.

setSourceLine :: SourcePos -> Line -> SourcePos

Set the line number of a source position.

setSourceColumn :: SourcePos -> Column -> SourcePos

Set the column number of a source position.

setSourceName :: SourcePos -> SourceName -> SourcePos

Set the name of the source.
