The sections below include the coding conventions with respect to statements.
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
andelse if
keywords in the same line with the matchingif
orelse if
block's closing brace separated only by a single space.
Empty block
- Do not have any empty
if
,else if
, orelse
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 => {} }
