Data.Char.Brackets
Description
Unicode considers 60 characters to be brackets: brackets are organized in pairs: each opening bracket has a corresponding closing bracket and vice versa.
The following characters are considered brackets where the first character is closed by the last character, the second by the last but one, etc.:
([{༺༼᚛⁅⁽₍⌈⌊〈❨❪❬❮❰❲❴⟅⟦⟨⟪⟬⟮⦃⦅⦇⦉⦋⦍⦏⦑⦓⦕⦗⧘⧚⧼⸢⸤⸦⸨〈《「『【〔〖〘〚﹙﹛﹝（［｛｟｢｣｠｝］）﹞﹜﹚〛〙〗〕】』」》〉⸩⸧⸥⸣⧽⧛⧙⦘⦖⦔⦒⦎⦐⦌⦊⦈⦆⦄⟯⟭⟫⟩⟧⟆❵❳❱❯❭❫❩〉⌋⌉₎⁾⁆᚜༽༻}])
These characters span over several code blocks.

Listing and converting brackets
bracketMaps :: [(Char, Char)] Source #
A list of 2-tuples where the first item of each tuple is the opening bracket, and the second item its closing counterpart.
The list of all brackets characters.
A list of Chars that contains all opening brackets.
A list of Chars that contains all closing brackets.
toOpen :: Map Char Char Source #
A Map that maps the given close bracket
characters to the corresponding open bracket.
toClose :: Map Char Char Source #
A Map that maps the given open bracket
characters to the corresponding close bracket.
Check the given bracket type
data BracketType Source #
A data type that is used to specify the type of bracket.
Constructors
| Open | The bracket is used to "open" a context. |
| Close | The bracket is used to "close" a context. |
Instances
bracketType :: Char -> Maybe BracketType Source #
Check the BracketType of the Char wrapped in a Just data construct;
Nothing if the given Char is not a bracket character.
bracketType' :: Char -> BracketType Source #
Check the BracketType of the Char. For a Char that is not a bracket
the behavior is unspecified.
Check if the given Char is an open bracket.
