NAME
llength - Count the number of elements in a listSYNOPSIS
llength listDESCRIPTION
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
