[issue43247] How to search for a __main__ module using pyclbr in Python3?
New submission from Aviral Srivastava :
I want to get all the functions and classes in module: `__main__` of the source
code directory: `/tmp/rebound/rebound`.
When I use the `pyclbr.readmodule_ex` API:
```
source_code_data = pyclbr.readmodule_ex(source_code_module,
path=source_code_path)
```
I specify it the module and it's path:
```
DEBUG:root:Source code module: __main__, Source code path:
['/tmp/rebound/rebound/rebound']
```
I then get this error:
```
File
"/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/importlib/util.py",
line 69, in _find_spec_from_path
raise ValueError('{}.__spec__ is None'.format(name))
ValueError: __main__.__spec__ is None
```
I then tried to use the function that is not supposed to be used by the public:
`_readmodule`:
```
source_code_data = pyclbr._readmodule(source_code_module, source_code_path, )
```
But I could not decide what should be the value of the parameter: `inpackage`.
Upon tracing the code via debugger, I spotted a mistake:
```
def _find_spec_from_path(name, path=None):
"""Return the spec for the specified module.
First, sys.modules is checked to see if the module was already imported. If
so, then sys.modules[name].__spec__ is returned. If that happens to be
set to None, then ValueError is raised. If the module is not in
sys.modules, then sys.meta_path is searched for a suitable spec with the
value of 'path' given to the finders. None is returned if no spec could
be found.
Dotted names do not have their parent packages implicitly imported. You will
most likely need to explicitly import all parent packages in the proper
order for a submodule to get the correct spec.
"""
if name not in sys.modules:
return _find_spec(name, path)
else:
module = sys.modules[name]
if module is None:
return None
try:
spec = module.__spec__
except AttributeError:
raise ValueError('{}.__spec__ is not set'.format(name)) from None
else:
if spec is None:
raise ValueError('{}.__spec__ is None'.format(name))
return spec
```
This is the function in the module: `python3.8/importlib/util.py` and it
evaluates `__main__` as a built-in module as it falls in the `else` block.
How do I differentiate `__main__` of my target source code to read from the
built-in `__main__`? In other words, how do I read the module `__main__` of the
codebase: rebound?

[issue38307] Add .end_lineno attribute to pyclbr _Objects
Aviral Srivastava added the comment: Hey Terry, thanks for commenting. I have a few questions to ask you, please pardon my lack of awareness. >This requieres end lines and having it be an attribute is easier and more >accurate than recalculating it. How do you recalculate the end_lineno? Since all the objects that _start_, have an _end_ too, would `end_lineno=None` make any sense? I could not make anything out of your third point where you mention `readline` and `readline_ex`. Can you explain that point? >I posted "What is the pyclbr public API" to pydev asking about this issue. Can you share the link of your post? As for my use case, I need the scope of a class and a function in the new tool that I am developing. My tool is to generate a new type of UML diagrams for a given codebase. Do check it out and leave your critical feedback: https://github.com/kebab-mai-haddi/gruml I need to know about the scope (start and end) so that I can deduce whether the "used_at" attribute of an object is within a class. This will help me deduce whether a particular class (or a function) uses any imported object. This is to deduce the dependency of a class on other classes and functions. Currently, I have to edit the pyclbr and make it custom, then, had to Dockerize the whole thing. So, want to contribute to `cpython` so that this feature is present at the source itself. -- ___ Python tracker <https://bugs.python.org/issue38307> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
