llength(3tcl) Tcl Built-In Commands llength(3tcl) 


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
