Bracket - an esoteric programming language

Numbers

• 0 → [] (equivalent to group of no statements)
• 1 → [()]
• 2 → [()()]
• 3 → [()()()]
• ...

Operators

• & (equivalent to +1)
• * (equivalent to -1)

Variables/Functions

• {x}()[y] - set value of variable x to y
• {x}[] - get value of variable x
• {x}(y)[z] - define function x with arguments y to return value z
• {x}[y] - call function x with arguments y
• statements can be grouped using [] (value of a group is the value of the last statement in it)

Conditionals

• [x] | [y] | [z] - if x != 0 then y else z

Variable/Function Names

• Valid bracket nestings only, e.g. (), (()), (()()), (()(())), etc.

Try-Catch

• <try_block|catch_block> - if error is encountered while executing try_block, execution continues from catch_block instead.

Print

• <x> - print x as a number
• <x|> - print x as a character
• Value of the statement is the value of x
