One space on each side of every binary operator (CodeCop AA0001)

Description

CodeCop AA0001 requires exactly one space on each side of every binary operator: assignment (:=), arithmetic (+, -, *, /, mod, div), comparison (=, <>, <, <=, >, >=), logical (and, or, xor), and string concatenation. x:=1+2, Price:=Amount*Quantity, if a=b then, and if a and b then all violate the rule. The rule applies to the binary use of - (subtraction); the unary minus (-Profit) takes no leading space.

Best Practice

Write x := 1 + 2, Price := Amount * Quantity, if a = b then, if a and b then. The standard AL formatter inserts these spaces automatically; running Alt+Shift+F (Format Document) in the AL extension is the simplest way to bring an entire file into compliance.

See sample: single-space-around-binary-operators.good.al.

Anti Pattern

x:=1+2;, Price:=Amount*Quantity;, if a=b then, if a and b then. All trip AA0001.

See sample: single-space-around-binary-operators.bad.al.
