Can't Load Empty List

[ed08724 6]

really beating my head against a wall here.

my code was working fine now all of a sudden I can't load a list from file and get empty

 

clear list(%test)
save to file("{$special folder("My Documents")}\\test.csv",%test)
add list to list(%test,$list from file("{$special folder("My Documents")}\\test.csv"),"Delete","Global")

 

when I run that I end up with a list with 1 blank item instead of a list with 0 items

this messes up all the rest of the code.

this is just a new snipit of code I wrote to test my issue.

 

 

thanks and happy holidays!

I have fixed the issue although don't know why its all of a sudden an issue.
load the file in as a table then convert to list

 

create table from file("{$special folder("My Documents")}\\test.csv",&test)
clear list(%test)

add list to list(%test,$plugin function("TableCommands.dll", "$list from table", &test, "Column", 0),"Delete","Global").

I think its because the file you create will still have the first line and so it will register as a list item. However, there are no values and so you get an empty list item and when you use a table you also get an empty table. If you convert the table to a list then it would have no items.

clear list(%test)
save to file("{$special folder("My Documents")}\\test.csv",%test)
add list to list(%test,$list from file("{$special folder("My Documents")}\\test.csv"),"Delete","Global")
remove from list(%test,0)

Remove from list

 

will take care of that item

Code Docta, that was just a test case. when there are actually items in the list I can't just delete the first 1

But you can check to see if it's blank, if that's what you're looking for?

 

Like so:

clear list(%test)
save to file("{$special folder("My Documents")}\\test.csv",%test)
add list to list(%test,$list from file("{$special folder("My Documents")}\\test.csv"),"Delete","Global")
if($comparison($trim($list item(%test,0)),"=",$nothing)) {
    then {
        remove from list(%test,0)
    }
    else {
    }
}
