linsert(n) Tcl Built-In Commands linsert(n)______________________________________________________________________________NAMElinsert - Insert elements into a list
SYNOPSISlinsert list index ?element element ...?
_________________________________________________________________DESCRIPTION
This command produces a new list from list by inserting all of the ele‐
ment arguments just before the index'th element of list. Each element
argument will become a separate element of the new list. If index is
less than or equal to zero, then the new elements are inserted at the
beginning of the list. The interpretation of the index value is the
same as for the command string index, supporting simple index arith‐
metic and indices relative to the end of the list.
EXAMPLE
Putting some values into a list, first indexing from the start and then
indexing from the end, and then chaining them together:
set oldList {the fox jumps over the dog}
set midList [linsert $oldList 1 quick]
set newList [linsert $midList end-1 lazy]
# The old lists still exist though...
set newerList [linsert [linsert $oldList end-1 quick] 1 lazy]
