llengthn

Usage

Overview

Treats list as a list and returns a decimal string giving the number of elements in it.

Examples

The result is the number of elements: % llength {a b c d e} 5 % llength {a b c} 3 % llength {} 0

Elements are not guaranteed to be exactly words in a dictionary sense of course, especially when quoting is used: % llength {a b {c d} e} 4 % llength {a b { } c d e} 6

An empty list is not necessarily an empty string: % set var { }; puts "[string length $var],[llength $var]" 1,0
