💻 show some roles of variables (constant, input constant, walker, container)

[juliabolt]

Adds roles in the variable list, works for four roles now, constant, input constant, container and walker.

How to test

Follow these steps to verify this PR works as intended:

• change the feature flag in debugging.ts called showRoles to true
• check that the variable list now shows roles of variables, in addition to the variable names and their values. (when using the Hedy debugger)
• run this example program in level 2 and see if it says naam is a constant

naam is Hedy
leeftijd is 10
leeftijd is 15
print naam is leeftijd jaar oud

• see if in level 2 the variables in this program are input constants

naam is ask Wat is je naam?
print Hoi naam
leeftijd is ask Hoe oud ben je?
print naam is leeftijd jaar oud

• run this example program in level 10 and see if it says that dier is a walker

dieren = hond, kat, papegaai
voor dier in dieren
  print dier ' is een leuk dier!'

• go to level 3 and see if dieren is a container in this example code

dieren is hond, kat, papegaai
print dieren at random

• change the feature flag back to false
• check that the variable list now looks like it normally does, with only the variable names and their values.

When testing the code with the additions in this PR, everything seems to work in level 1 to 5, but from level 6 on, random things seem not to work, like calculations in level 6 and the repeat command in level 7.
This already seems to go wrong, before ever getting to the function determine_roles that I added in hedy.py (when using the debugger and putting a breakpoint in that function). This happens no matter if the feature flag is false or true.

Issue in former comment is solved! thanks @jpelay :)

I fixed the parsing problem! But now it's not showing output when in some programs, for example this one of level 12:

a is 2
b is 3
for a in range 2 to 4
    a is a + 2
    b is b + 2

There's a response and the program is shown as executed, perhaps it has to do with the fact that the variables has a type of unknown?

[juliabolt]

The type unknown should not work any differently than the other types, it's just a string in a dictionary...

I still get issues trying to test this code, ModuleNotFoundError: iso639 (see app.py line 22)

[juliabolt]

I get this when I try your example code in Hedy level 12

[juliabolt]

I don't get that error in alpha, but it is normal that there is no output in that program :P

[jpelay]

I don't get that error in alpha, but it is normal that there is no output in that program :P

HAHA you're right! oops

Do the pip thing again!
