deadcode's Issues

Always True ifs are removed

Nice package. I did run into the following problem. When I try to run deadcode --fix on the following

a=0
if True:
    a=1
    print(a)

print(a)

then it changes it to

a=0
print(a)

The expected behaviour would be

a=0
a=1
print(a)
print(a)

or just leaving the if intact.

noqa doesn't work for decorated functions

With an unused function, this works:

def check(arg):  # noqa: DC002
    pass

but this doesn't:

@cache
def check(arg):  # noqa: DC002
    pass

This works again, but I don't think it should be valid:

@cache  # noqa: DC002
def check(arg):
    pass

Adding more decorators yields an error again.

[feat] remove code

@albertas I would like to know if it is possible or if there is a way for me to automatically delete this indicated code?

[fix] library not installed

After installing your library I needed to manually install "tomli" library

Traceback (most recent call last):
  File "/Users/luis/.pyenv/versions/lambda_poc_ai/bin/deadcode", line 5, in <module>
    from deadcode.cli import main
  File "/Users/luis/.pyenv/versions/3.10.12/envs/lambda_poc_ai/lib/python3.10/site-packages/deadcode/cli.py", line 5, in <module>

[bug]: Deadcode --fix removes the `f` character from the `from` keyword in `from module import (a,b,c,)`

deadcode version:

[[package]]
name = "deadcode"
version = "2.2.2"
description = "Find and remove dead code."
category = "dev"
optional = false
python-versions = ">=3.8"
files = [
    {file = "deadcode-2.2.2-py3-none-any.whl", hash = "sha256:d8280cf44e224e47e061f9b9963b902c009dc1ba1e43a42623a43ab88e1afa36"},
    {file = "deadcode-2.2.2.tar.gz", hash = "sha256:b63e207999667e731212e04f6d48888a2e3f7256e5ee808ba9082af20d99dca0"},
]

Python version:

Python 3.11.7

To reproduce, create the following two files in the same directory:

file1.py:

foo = 1
bar = 2
xyz = 3

file2.py:

from file1 import (
    foo,
    bar,
    xyz
)

from file1 import foo

def fn():
    pass

fn()

Run deadcode with --fix

🐍 v3.11.7 (myapp-py3.11) 
✗  deadcode ./file2.py --fix
file2.py:1:0: DC007 Import `bar` is never used
file2.py:1:0: DC007 Import `foo` is never used
file2.py:1:0: DC007 Import `xyz` is never used
file2.py:7:0: DC007 Import `foo` is never used

Removed 4 unused code items!

I expect all of the imports to be removed, but this what file2.py looks like afterwards instead:

rom file1 import (
    foo,
    bar,
    xyz
)

def fn():
    pass

fn()

It removes the f in from, and doesn't get rid of those imports.
