LRANGE — Querying List Ranges

LRANGE returns a slice of the list without removing elements.

Syntax

LRANGE key start stop — returns elements from index start to stop, inclusive.

Indexing

• 0-based from the left: 0 = first, 1 = second
• Negative from the right: -1 = last, -2 = second-to-last
• LRANGE key 0 -1 returns all elements

Out of Range

Out-of-range indices are clamped — no error. If start > list length, returns empty array.

RESP Array Format

*3\r\n$5\r\nalice\r\n$3\r\nbob\r\n$7\r\ncharlie\r\n

The *3 prefix says "3 elements follow", then each element is a bulk string.

Non-existing keys return empty array: *0\r\n
