Custom Functions?

fboteroh 03 Mar 2013 23:30

I'd like to write my own customized functions (including arguments) which I'd like to call from different scripts. Is it possible?

The Aseba Language is simple but powerful enough to manage also complex coding.
In Aseba there are not custom function as you can find in other languages. There are only subroutines without arguments.
All the variables are global.
You can use subroutines in order to implement something very similar to functions. You can declare global variables conventionally tied to a subroutine and use them for passing arguments and get back results.

var f1_arg1
var f1_arg2
var f1_arg3
var f1_res

var X

sub f1
f1_res = f1_arg1 * f1_arg2 + f1_arg3

# Now You can call pseudofunction f1 as follow:
# initialize arguments
f1_arg1=10
f1_arg2=3
f1_arg3=4
# Call the pseudofunction
callsub f1

x = f1_res  #The result will be x assigned to 34

This code is safe just only because you cannot call the function in a recursive way (also indirect). This coding is not re-entrant safe but also re-entrant programming is not possible (interrupts are not managed at all).

Very advanced users can reprogram the Thymio firmware and add their own native function. However, we cannot provide technical support for these modified firmwares. It is also at the users' own risks because these firmwares can damage the electronics.
