Loop problems

[maxgerhardt]

With my referenced project

>>> for i in range(0, 10):
... print(i)
[error] print: can not print val
   REF i                (#56)
 -> RUN print           (#63)

And while loops hang up completely

>>> i = 0
>>> i
0
>>> while i != 10:
... i +=1

<hangs>

When okay that might have been due to missing spaces in the second line, but with them I just get syntax error.

>>> for i in range(0, 10):
...    print(i)
... 
[error]: Syntax error.

Only support 4 spaces

Now more error info is supplied.

No space is also wrong in CPython. The robustness of PikaScript is not good enough for wrong input, so checking it in CPython first may be helpful.

Indeed you're right, the 4 spaces is really important.

>>> for i in range(0,10):
...     print(i)
...
0
1
2
3
4
5
6
7
8
9
>>> i = 0
>>> while i != 10:
...     i += 1
...
>>> i
10

But maybe throwing an IndentationError would be better.

Also things that would be syntax errors are not marked as one but just execute

>>> while i != 10
>>> 

vs

>>> while i != 10
  File "<stdin>", line 1
    while i != 10
                ^
SyntaxError: invalid syntax

But anyways this error was on my side.

It's true that the error checker is need enhancement.
