Operators

Unary

• Unary operators should have no whitespace between themselves and the argument.

Binary

• Colons (a:b), powers (x^y and family), type declarations (a::T) and dots (a.b) should have no whitespace between operators and arguments.
• All other operators should have surrounding white space, except:
  • When the arguments of a colon (:) expression are binary expressions with no surrounding brackets, no white space should be used. (i.e. a + b * c:d -> a+b*c:d or (a + b * c):d

Ternary: a ? b : c

• Ternary conditional expressions should have (and in future versions must have) whitespace between arguments and operators.

Brackets: (), [], {}

• There should be no whitespace between the opening bracket and first item.
• There should be no whitespace between the final item and the closing bracket.
• Unless a single item Tuple is being constructed, there should not be a comma before the closing bracket.

Commas

• Commas should have no preceding whitespace and a single trailing space except:
  • When separating items in curly brackets, where there should be no surrounding white space i.e. {a,b}.

Line-length

• Lines exceeding 92 characters should be split.
• There should be no white space at the end of lines.
• There should be one blank line at the end of a file.

Symbol Naming

• Functions should be lowercase.
