Language: Kotlin

Severity: Notice

Category: Best Practices

Description

This rule ensures that all if/else expressions in your Kotlin code are always enclosed in braces {}. This is important for readability and to prevent potential errors. When braces are omitted in if/else expressions, it can lead to confusion about which statements are included in the conditional block, especially in complex codebases.

Non-Compliant Code Examples

fun func(value: Int) {
    if (value > 0)
        foo()
    else if (value < 0) {
        bar()
    } else
        baz()
}

Compliant Code Examples

fun func(value: Int) {
    if (value > 0) {
        foo()
    } else if (value < 0) {
        bar()
    } else {
        baz()
    }
}
