An extension of argparse with history tracking

HistoryArgumentParser

Why Track Command History?

Have you ever found yourself wondering:

• "What parameters did I use for that successful run last week?"
• "How can I replicate the exact configuration from my previous experiments?"
• "Is there an easy way to audit how my script has been used over time?"
• "How can I track my program's performance changes depending on its parameters?"

HistoryArgumentParser is here to solve these problems and more!

What is HistoryArgumentParser?

HistoryArgumentParser is an extension of Python's built-in argparse.ArgumentParser that automatically tracks and stores the command-line arguments used in your scripts. It's designed to be a drop-in replacement for ArgumentParser, adding powerful history tracking capabilities with minimal changes to your existing code.

Key Features

• 📜 Automatic command history tracking
• 🕰️ Timestamped entries for easy reference
• 🔍 Built-in history viewing functionality
• 🔍 Tracking execution statistics, or any other relevant data depending on the arguments
• 📁 Customizable history file location
• 🔌 Seamless integration with existing argparse code

Installation

Install HistoryArgumentParser with pip:

pip install argparse_history

Quick Start

Replace your existing ArgumentParser with HistoryArgumentParser:

from history_argparse import HistoryArgumentParser

parser = HistoryArgumentParser(description="Your script description")
parser.add_argument('--input', help='Input file', required=True)
parser.add_argument('--output', help='Output file', required=True)

args = parser.parse_args()

# Your script logic here

That's it! Your script now tracks command history automatically.

Viewing Command History

To view the command history, simply run your script with the --show-history flag:

python your_script.py --show-history

This will display a list of previous runs with their timestamps and arguments.

python your_script.py --show-stats

In addition to the arguments history this will display any data saved during program runs.

Customizing History File Location

By default, the history is stored in the current directory. You can specify a custom directory:

python your_script.py --input in.txt --output out.txt --history-dir /path/to/history

Why Choose HistoryArgumentParser?

1. Effortless Integration: Minimal changes to your existing code.
2. Improved Reproducibility: Easily recreate previous runs.
3. Better Debugging: Quickly identify what parameters were used in past executions.
4. Audit Trail: Keep track of how and when your script is being used.
5. Execution statistics: keep track of your script performance, or any other relevant data, depending on its parameters.
6. Time-Saving: No more manual logging of script parameters.
