lindex(n) Tcl Built-In Commands lindex(n)
__________________________________________________________________________________________________________________________________________________
NAME
lindex - Retrieve an element from a list
SYNOPSIS
lindex list ?index...?
_________________________________________________________________
DESCRIPTION
The lindex command accepts a parameter, list, which it treats as a Tcl list. It also accepts zero or more indices into the list. The |
indices may be presented either consecutively on the command line, or grouped in a Tcl list and presented as a single argument. |
If no indices are presented, the command takes the form: |
lindex list |
or |
lindex list {} |
In this case, the return value of lindex is simply the value of the list parameter. |
When presented with a single index, the lindex command treats list as a Tcl list and returns the index'th element from it (0 refers to the
first element of the list). In extracting the element, lindex observes the same rules concerning braces and quotes and backslashes as the
Tcl command interpreter; however, variable substitution and command substitution do not occur. If index is negative or greater than or
equal to the number of elements in value, then an empty string is returned. If index has the value end, it refers to the last element in
the list, and end-integer refers to the last element in the list minus the specified integer offset.
If additional index arguments are supplied, then each argument is used in turn to select an element from the previous indexing operation, |
allowing the script to select elements from sublists. The command, |
lindex $a 1 2 3 |
or |
lindex $a {1 2 3} |
is synonymous with |
lindex [lindex [lindex $a 1] 2] 3 |
EXAMPLES
|
lindex {a b c} => a b c |
lindex {a b c} {} => a b c |
lindex {a b c} 0 => a |
lindex {a b c} 2 => c |
lindex {a b c} end => c |
lindex {a b c} end-1 => b |
lindex {{a b c} {d e f} {g h i}} 2 1 => h |
lindex {{a b c} {d e f} {g h i}} {2 1} => h |
lindex {{{a b} {c d}} {{e f} {g h}}} 1 1 0 => g |
lindex {{{a b} {c d}} {{e f} {g h}}} {1 1 0} => g |
