+=, -=, *= and /= do not work

[SquaredTiki]

Running the following code:

 NSInteger num = 235

And then the following produces errors or does not return the correct value:

+= does not change the value

run: num += 5
5
Not assignable at 'num `+= 5'
out: 5

-= does not change the value

run: num -= 5
 5
 Not assignable at 'num `-= 5'
 out: 5

*= does not change the value

 run: num *= 5
 out: 5

/= produces an error

 run: num /= 5
 expecting scope at 'num `/= 5'
 break

C-style arithmetic is not supported. This stems from the primary goal of Tosti, to not be a C interpreter. I do plan to add support for infix operators like +-*/, but also &|^< etc. Until then, you can use the helper functions defined in TOMath, e.g.:

num = add(num, 5)

[SquaredTiki]

I understand but since the infix operators are commonly used in using objective-c would it not be worth including them here? Or are you trying to restrict Tosti to pure objective-c?

[leovandriel]

No need to restrict Tosti, not just yet :). It's more about the primary goals and where to spend my time. I agree with you that it would be worth including them, it's just not a trivial task.

Understood Leonard. Thanks for the info!
