gives you 7

But i am stuck here:

How to force the calculation here ?The var a is a result of regex so its all characters.



thanks

Hubert

What do you mean solved?

I know that a:=5+2 is 7 but that is not what i asked!!!


example



Maybe i should have given an example in my first post

Maybe you should carefully read the help page for the RegexReplace "replacement" argument".

This is probably the best you will get:

What you suggested maybe possible with "regex callouts", which ahk does not provide, but even if it did, you would still need an external function to to the maths.

thanks wanse

but it is not only regex that is why i gave the first example ( maybe misleading)

data=aa5a+a6
Stringreplace,a,data,a,,all


a = 5+2

If you want to force it to calculate the "string" "5 + 2" contained in var a there is no way to do it?

You can get this same string from other string manipulations than regex but in the end you are stuck if you want to ahk see it as an expression?

something like result :=a + 0 ( tried but does not work )

Unless the workaround you propose.

Ok, these two links demonstrate how to evaluate expressions in strings.
Monster: evaluate math expressions in strings
Popup calculator / expression evaluator
If you search the forums, I think there are a couple of other demonstrations of how to do it.

oops, got the links mixed
Monster: evaluate math expressions in strings
Popup calculator / expression evaluator

A while loop will get it:





AHK does not but AutoHotkey_L does. I don't think callouts will necessarily help here since you must know the number of matches you're going to have ahead of time.

Well, the rest of my statememnt was And that is still true with AHK_L.

And there is a drawback to AHK_L (besides learning a new set of idiosyncrasies/bugs) and that is that Win9x compatibility is lost. Maybe it is not an issue for you, but for me and a few others, it is a concern

thank you all


to hd0202 sorry i should have made my question clearer ( i had been going over the problem for 2 hours..........)

to sinkfaze looks like the best solution i can get,when i asked the question i thought it would be some trick like the forcing of expression by % var

to wanze thanks i looked at the calculator it solves the problem using a coded function but your first regexmatch solution was an easier way to do it for that case.(maybe not an universal solution )
