pyaphid 0.2.0

Identify unwanted function calls in your code

Pyaphid

Description

Pyaphid is a static analysis tool for detecting unwanted function calls in Python code.

Installation and usage

Installation: pip install pyaphid

Usage: python -m pyaphid <files and/or directories to analyze> or pyaphid <files and/or directories to analyze>

Configuration

Forbidden function calls can be configured via the pyproject.toml:

[tool.pyaphid]
forbidden = [
    "print", # forbid print(...)
    "pdb.run", # forbid pdb.run(...)
    "werkzeug.debug.*", # forbid werkzeug.debug.DebuggedApplication(...), werkzeug.debug.get_machine_id(...), ...
    "datetime.datetime.now" # forbid datetime.now()
]

With datetime.now for example you usually want to ignore one call to it for implementing a project-wide default function. You can use # pyaphid: ignore to ignore a line:

from dateutil.tz import tzlocal
from datetime import datetime

def get_now():
  # allowed
  return datetime.now(tzlocal()) # pyaphid: ignore

datetime.now() # forbidden

CLI Options

• -n / --names: Look-up all func calls and print their identifier

my_print("Hello world") # undetected
