llength(n) Tcl Built-In Commands llength(n)
NAME
llength - Count the number of elements in a list
SYNOPSIS
llength list
DESCRIPTION
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
