lsort

[Thodd]

Hello,

I have a list that I want to sort, but I can't get it right.
The pckt-array has a timestamp and a value on each line and is sorted by the timestamp.

set pcktlst ""
foreach {name value} [array get pckt] {
lappend pcktlst $name $value
}
set pcktlst [lsort -integer -index 0 $pcktlst]
#now the $name should be deleted out of the list so that only the values remain.

So I'd like to have a pcktlst with only the values, in the same order they appear in the pckt-array.
How can I get that?

thx

I'm not sure I follow but I think you need a list of lists to do the sort you want. That is, set pcktlst [lsort -integer -index 0 $pcktlst] is sorting the list on the 0th element of the elements of that list. That is, in your case, your list would have to be of the form: {{time value} {time value} ...}. What about this:

foreach {name value} [array get pckt] { 
lappend pcktlst [red]"[/red]$name $value[red]"[/red]
}
set pcktlst [lsort -integer -index 0 $pcktlst]
#now the $name should be deleted out of the list so that only the values remain:
foreach pair $pcktlst {lappend valList [lindex $pair 1]}
