Data.GraphViz.Types.Parsing
Description
This module defines simple helper functions for use with Text.ParserCombinators.Poly.Lazy.
Note that the ParseDot instances for Bool, etc. match those
specified for use with GraphViz (e.g. non-zero integers are
equivalent to True).
You should not be using this module; rather, it is here for
informative/documentative reasons. If you want to parse a
Data.GraphViz.Types.DotGraphData.GraphViz.Types.parseDotGraphParseDot
instance.

Methods
parseUnqtList :: Parse [a]Source
Instances
quotedString :: Parse StringSource
Used when quotes are explicitly required;
parseAndSpace :: Parse a -> Parse aSource
optionalQuoted :: Parse a -> Parse aSource
quotedParse :: Parse a -> Parse aSource
Consume all whitespace and newlines until a line with non-whitespace is reached. The whitespace on that line is not consumed.
tryParseList :: ParseDot a => Parse [a]Source
tryParseList' :: Parse [a] -> Parse [a]Source
parseField :: ParseDot a => String -> Parse aSource
parseFields :: ParseDot a => [String] -> Parse aSource
parseFieldBool :: String -> Parse BoolSource
parseFieldsBool :: [String] -> Parse BoolSource
parseFieldDef :: ParseDot a => a -> String -> Parse aSource
For Bool-like data structures where the presence of the field
name without a value implies a default value.
parseFieldsDef :: ParseDot a => a -> [String] -> Parse aSource
