Forums Scripts & Popups Deleting the last character in a variable

im trying to write an alias that will delete the last charachter/numberic or char in a variable
like example

if the varable is called %myvar and it has 1 2 3 4

%myvar 1 2 3 4
and you wanted to delete the 4 after, (not cause it was a 4, just cause it was the last char)

is there an easy way to create a alias that will delete the last charachter in a variable?

//set %myvar $gettok(%myvar,$+(1,-,$calc($numtok(%myvar,32) - 1)),32)

//set %var $deltok(%var,-1,32)

Btw to the OP: I think you are confusing a char with a token (they can be the same but not necessarily). What if the %var was 10 20 30, taking out the last char would mean taking out the 0 from 30, but taking out the last space delimited token would mean taking out the 30. The current solution with $deltok takes out a token. A char based solution would be something like //set %var $left(%var,-1)

Or that, but I've always done things the hard way.. :tongue:

LOL, and I would have gone with $remove(%myvar,$right(%myvar,1)).

But supposing you have numbers in %myvar 1-10.

/set %myvar 1 2 3 4 5 6 7 8 9 10

//echo -a $remove(%myvar,$right(%myvar,1))

You'll get 1 2 3 4 5 6 7 8 9 1

I know you didn't propose $remove as a solution, so it's no offense or anything, but I'd like to point out why exactly $remove is a bad idea to use in cases such as these and similar.

Say his var was:

%var 10 15 16 11

$right(%var,1) = 1
$remove(%var,1) = 0 5 6

In other words, that would screw up the entire variable rather than just delete the last char. In general, one should only use $remove if one doesn't mind all occurences to be removed. If you want to only delete certain matches, then $remove is a not the way to go.

True, didn't think of that. I guess that's why you have almost 3000 more posts than I do!

Thanks it works perfect
you guys are always awesome

3? :tongue:
