- .SH NAME
- linsert - Insert elements into a list
- .SH SYNOPSIS
- fBlinsert fIlist index element fR?fIelement element ...fR?
- .BE
- .SH DESCRIPTION
- .PP
- This command produces a new list from fIlistfR by inserting all of the
- fIelementfR arguments just before the fIindexfR'th element of
- fIlistfR. Each fIelementfR argument will become a separate element of
- the new list. If fIindexfR is less than or equal to zero, then the new
- elements are inserted at the beginning of the list. If fIindexfR has the
- value fBendfR, or if it is greater than or equal to the number of
- elements in the list, then the new elements are appended to the list.
- fBend-fIintegerfR refers to the last element in the list minus the
- specified integer offset.
- .SH EXAMPLE
- Putting some values into a list, first indexing from the start and
- then indexing from the end, and then chaining them together:
- .CS
- set oldList {the fox jumps over the dog}
- set midList [fBlinsertfR $oldList 1 quick]
- set newList [fBlinsertfR $midList end-1 lazy]
- # The old lists still exist though...
- set newerList [fBlinsertfR [fBlinsertfR $oldList end-1 quick] 1 lazy]
