## Metadata{% #metadata %}

**ID:** `kotlin-code-style/if-else-wrapping`

**Language:** Kotlin

**Severity:** Notice

**Category:** Code Style

## Description{% #description %}

Inconsistent formatting of our if/else statements could mislead you to their structure, especially if you have multiple nested if/else statements.

- Use braces whenever you nest an 'if' statement inside another 'if' statement, except for `if ... else if ...` sequences.
- If one of the branches of the 'if' statement uses braces, use braces in both branches.
- Short, single-line branches of an 'if' statement should not use braces. If you must use braces, split it into several lines.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```kotlin
fun foobar() {
    if (true) if (false) foo()
    if (true)
        foo()
    else
        if (false)
            bar()
    if (true) { foo() }
    if (true) {
        foo()
    } else { bar() }

    if (true) {
        foo()
    } else bar()
    if (true) foo()
    else {
        bar()
    }
}
```

## Compliant Code Examples{% #compliant-code-examples %}

```kotlin
fun foobar() {
    if (true) foo()
    if (true) foo() else bar()
    if (true) foo() else if (false) bar() else baz()

    if (true)
        foo()
    else if (false)
        bar()

    if (true)
        foo()
    else
        bar()

    if (true) {
        if (false) foo() else bar()
    } else {
        bar()
    }
}
