This module defines internal utility functions.

Synopsis

valueisIDString :: Text -> Bool

valuefrstIDString :: Char -> Bool

First character of a non-quoted String must match this.

valuerestIDString :: Char -> Bool

The rest of a non-quoted String must match this.

valueisNumString :: Bool -> Text -> Bool

Determine if this String represents a number. Boolean parameter determines if exponents are considered part of numbers for this.

valuetoDouble :: Text -> Double

This assumes that isNumString is True.

valueisIntString :: Text -> Bool

valuestringToInt :: Text -> Maybe Int

Determine if this String represents an integer.

valueescapeQuotes :: String -> String

Graphviz requires double quotes to be explicitly escaped.

valuedescapeQuotes :: String -> String

Remove explicit escaping of double quotes.

valueisKeyword :: Text -> Bool

valuekeywords :: Set Text

The following are Dot keywords and are not valid as labels, etc. unquoted.

valuecreateVersion :: [Int] -> Version

valueuniq :: Ord a => [a] -> [a]

valueuniqBy :: Ord b => (a -> b) -> [a] -> [a]

valuegroupSortBy :: Ord b => (a -> b) -> [a] -> [[a]]

valuegroupSortCollectBy :: Ord b => (a -> b) -> (a -> c) -> [a] -> [(b, [c])]

valuebool :: a -> a -> Bool -> a

Fold over Bools; first param is for False, second for True.

valueisSingle :: [a] -> Bool
