importless 0.1.1

Deboalt your code by removing unused import statements

ImportLess

ImportLess is a command-line tool designed to help Python developers generate minimal dependency lists by analyzing the actual imports used in their source code. This makes your requirements.txt lean, accurate, and free from unused or redundant packages.

Why ImportLess?

Managing dependencies in Python projects can be tricky:

• requirements.txt files often include packages no longer used.
• Manual dependency tracking is error-prone and time-consuming.
• Over-installed dependencies increase project size and complexity.

ImportLess automates this process by:

• Scanning your Python files for actual import statements.
• Filtering and identifying the exact packages your project depends on.
• Helping you keep your dependency list minimal and up to date.

---

Features

• Comprehensive scanning of Python source files in any directory.
• Supports both top-level and detailed import listings.
• CLI progress display with rich formatting using the rich library.
• Configurable scanning delay to simulate progress or manage performance.
• Clear, formatted output tables of detected imports.
• Designed to be extensible and modular.

Installation

Prerequisites

• Python 3.8 or higher
• pip package manager

Install from PyPI

Simply run:

pip install importless

Install from Source

If you prefer the bleeding edge or want to contribute:

git clone https://github.com/yourusername/importless.git
cd importless
pip install -e .

This will install the package in editable mode so you can modify and test easily.

---

Quick Start

Navigate to your Python project directory, then run:

importless scan

This will scan the current directory and show the top-level imports detected.

To see all imports (including from from module import name style), use:

importless scan --all

If you want to slow down scanning to watch the progress bar more clearly (default delay is 0.05 seconds), specify the delay:

importless scan --delay 0.1

---

Command Reference

scan

Scans the specified directory for Python files and extracts import statements.

Arguments

• path (optional): Directory path to scan. Defaults to the current directory (.).

Options

• --all (flag): Show all imports instead of just top-level imports.
• --delay FLOAT: Time delay (in seconds) between processing each file. Default is 0.05.

Examples

# Scan current directory, show top-level imports only
importless scan

# Scan a specific project directory, show all imports
importless scan --all ./myproject

# Scan with no delay for faster results
importless scan --delay 0

How It Works

1. File Discovery: Uses filewalker utility to recursively find all .py files in the target directory.
2. Source Parsing: Reads each Python file and analyzes it for import statements using the analyze_source core function.
3. Import Extraction: Collects import details such as the module name, imported names, and aliases.
4. Filtering: By default, only top-level imports (e.g., import module) are shown unless --all is specified.
5. Presentation: Shows a nicely formatted table of imports using the rich library and prints summary messages.
