I have two lists I'd like manipulate.. ( I am a tcl newbie..). I'd like to associate these two lists and create a third list with some data added.
The data I have:
set aes {ae0 ae3 ae6 ae1v1 ae1v8}
set c {c1 c2 c3 k1 k2}
foreach A $aes {
foreach C $c {
puts ${A}_$C
}
}
The data I get as you'd expect is: ae0_c1 ae0_c2 ae0_c3 ae0_k1 ae0_k2 .. ..
What I want to do is
append some data in front of this.
AE-To-c = All ae0_c1 ae0_c2 ae0_c3 ae0_k1 ae0_k2 .. End.
% set aes {ae0 ae3 ae6 ae1v1 ae1v8}
ae0 ae3 ae6 ae1v1 ae1v8
% set c {c1 c2 c3 k1 k2}
c1 c2 c3 k1 k2
% foreach A $aes {
foreach C $c {
# saving into 'result' variable
lappend result ${A}_${C}
}
}
% set data "some more here"
some more here
% set result
ae0_c1 ae0_c2 ae0_c3 ae0_k1 ae0_k2 ae3_c1 ae3_c2 ae3_c3 ae3_k1 ae3_k2 ae6_c1 ae6_c2 ae6_c3 ae6_k1 ae6_k2 ae1v1_c1 ae1v1_c2 ae1v1_c3 ae1v1_k1 ae1v1_k2 ae1v8_c1 ae1v8_c2 ae1v8_c3 ae1v8_k1 ae1v8_k2
% set result [linsert $result 0 $data]
some more here ae0_c1 ae0_c2 ae0_c3 ae0_k1 ae0_k2 ae3_c1 ae3_c2 ae3_c3 ae3_k1 ae3_k2 ae6_c1 ae6_c2 ae6_c3 ae6_k1 ae6_k2 ae1v1_c1 ae1v1_c2 ae1v1_c3 ae1v1_k1 ae1v1_k2 ae1v8_c1 ae1v8_c2 ae1v8_c3 ae1v8_k1 ae1v8_k2
Your question isn't 100% clear. Is it something like this you want?
set res [list AE-To-c = All]
foreach A $aes {
foreach C $c {
lappend res ${A}_$C
}
}
lappend res End
If you want to do what I think you want to do, you need to capture the permutations of the two lists in a list instead of printing them out, and then wrap that list in a prefix and suffix.
The method above pre-loads the result list with the AE-To-c = All prefix, then picks up the permutations using lappend, and finally adds the End suffix as a last element in the list.
Another way:
set res [list]
foreach A $aes {
foreach C $c {
lappend res ${A}_$C
}
}
concat [list AE-To-c = All] $res End
In this variant the list of permutations is created first, and then the prefix list, the permutation list, and the suffix list (yes, End is a list) are concatenated into one flat list.
