Array pop help. Want to pop last line in array.

[John Day]

I am trying to figure out how I can pop the Last entry in an array. The problem is the list could be any size and the Array pop command wants a static position and will not accept a variable position such as #< since I don't know what the last position will be I don't know how to pop it. Anyone have an idea how to do this? Thanks in advance

[Matt R]

Max out the position number (I think 999999).  That will remove the last element (unless your array is longer than 999999 elements...).

I could be wrong, but set variable %pop to %array(#), and pop position %pop.

%pop should equal the last index number of the array.

> I could be wrong

Close...

From the guide..

%arr(#)
The number of defined array elements (4 in this case)
%arr(#>)
The index of the first defined array element, or 0 if none are defined (1).
%arr(#<)
The index of the last defined array element, or 0 if none are defined (4)

, but set variable %pop to %array(#), and pop position %pop.

So to do it this way I think you need..

%arr(#<)

[Brandon Horwath]

Hmm. That sounds right.

I though %arr(#) would always equal %arr(#<), but maybe empty indexs are counted with one and not the other.

[Brandon Horwath]

Yep. I see. Defined vs. Last.

I would recommend Matt's suggestion ( he usually has a good reason for the approach he chooses) I have not tested this but to use  %arr(#<) in the pop action you might need to set it to a local variable first..   :)

"but set variable %pop to %array(#), and pop position %pop."

As far as I can tell it will only accept a number such as 1 or 39 or 999 it wont let me use a variable for the position hence my deli-ma.

I use this a lot...

Lots of ways to skin a cat with tasker, but I do:

Var Set %last to %arr(#<)
Array Pop %arr(%last)

As was suggested a few times. It works. I agree with Rich though...Matt usually has the best approach.

Sounds like beginner mode may be enabled. If so, Menu > Preferences > UI Tab > Beginner mood uncheck.

Great will give these Ideas a try thanks for all the help

[Brandon Horwath]

If you can't use a variable (by selecting the 'alternate' icon above the field [not present]) then yes, disable beginner mode.

[John Day]

I dont have beginner mode on, just saw it will let me press the icon and select a variable but will not let me type the variable by hand.  Weird but the is away around it thanks again for the info.

Can not recall the exact reason for this but I do believe it is the way it is supposed to be.

Yes.
1. Use Matt's suggestion and set it to 99999

2. Use Jeremy's suggestion and set a local variable to %arr(#>) then use that variable in the pop action.

[John Day]

got it. works good on to the next step THANKS GUYS!
