If statement

• Avoid enclosing the condition with parentheses.

Do's

if valid {
    ...
} else if active {
    ...
}

Don'ts

if (valid) {
    ...
} else if (active) {
    ...
}

• Keep the else and else if keywords in the same line with the matching if or else if block's closing brace separated only by a single space.

Empty block

• Do not have any empty if, else if, or else blocks.
• If empty, add an empty line between the opening and closing braces.

Example,

if inProperSallaryRange {
      
} else if inSallaryRange {
      
} else {
      
}

Match statement

Match patterns clause

• Block indent each pattern clause in its own line.
• Keep a single space before and after the => sign.

Example,

function foo(string|int|boolean a) returns string {
    match a {
        12 => {
            return "Value is '12'";
        }
    }
  
    return "Value is 'Default'";
}

• If a pattern clause has more than one statement, block indent each statement in its own line.

Example,

match x {
    var [s, i] if s is string => {
        io:println("string");
    }
    var [s, i] if s is int => {
        io:println("int");
    }
}

• If the pattern body is empty, then keep it as an empty block.

  Example,

match x {
    var [s, i] if s is string => {}
    var [s, i] if s is int => {}
}
