Count nested control structures gives weird output for python 3

[sak96]

For python the nested control structure stack up until a "}" structure is found. had trouble figuring out the issue. This may be because the structure for end of function is marked by "}" in case of C, C++, JAVA, whereas indentation in case of python

for the following code (filename give as comment)

# test.py
def foo():
    if bar:
        return

def foo1():
    if bar:
        return

def foo2():
    if bar:
        return

# test2.py
def foo():
    if bar:
        return

def foo1():
    a = {}
    if bar:
        return

def foo2():
    if bar:
        return

the output was:

This is a bug. Will find some time to fix it.

[sak96]

finally got some time.

did some digging:

This code in nesting run when token is '}' https://github.com/terryyin/lizard/blob/a2b8cdb5e83a6514c183bc30e59570fadcc1cadd/lizard_ext/lizardns.py#L90

which flows to https://github.com/terryyin/lizard/blob/a2b8cdb5e83a6514c183bc30e59570fadcc1cadd/lizard_ext/lizardns.py#L104

which sets the nesting level to 0 as the token is not if else.

i don't see that this is easily fixable issue. closing as this project is not active. making this issue stale.
