How to remove blank lines from list?

[Kreatus (Ubot Ninja) 422]

This maybe very easy but I cant find on the forum how to do it..

 

For example I have this list:

 

item1

item2

 

item3

 

item4

item5

 

How can I remove those empty lines?

 

Thanks

Two ways come to mind. Test the variable before adding to the list. If the items being added are truly unique then you could set the option to remove duplicates and that would remove all blank lines. But I still would test before adding to the list.

I ran into this problem, the tricky aspect of it is that when you delete a row all the other rows shift up.

 

The way I did it was like this (it's quite robust way of doing it so i can use it for other situations)

 

#listposition = ($list total - 1);
Loop $list total
{

  If ($list item == $nothing)
  {
      #remove rows += (list position + ",")
  }

#listposition--
}

 

This gets me a variable "#remove rows" with all the rows that need to be deleted. I then create a list from that variable with "add to list" and use the "," i added as the delimiter. I then loop over each list item and delete the row.

 

The code above adds the highest list reference first so when you loop to "remove row" deleting the row doesnt effect the other row numbers.

Is there not a sort list option?

 

Sort, then add to list and remove duplicates (in this case the spaces)

 

 

Not tested, just going off a vague memory.
