A simple command-line application to track your daily water intake and monitor progress toward your hydration goals.

Features

• Track Water Intake: Log water consumption in milliliters
• Daily Progress: View your progress toward the daily goal with a visual progress bar
• Persistent Data: Automatically saves your data to data.json
• Easy-to-use CLI: Simple command-line interface with intuitive arguments

Prerequisites

• Python 3.8 or higher

Installation

1. Clone or navigate to this directory
2. No external dependencies required (uses only Python standard library)

Usage

Adding Water Intake

Log your water intake in milliliters:

python hydra.py --add 500

This adds 500 mL to today's water intake.

Viewing Daily Statistics

Display your progress toward the daily goal:

python hydra.py --stats

Output example:

[█████░░░░░] 50% (1.25L / 2.5L)

Combining Arguments

You can combine both arguments:

python hydra.py --add 500 --stats

Daily Goal

The default daily water intake goal is 2.5 liters (2500 mL). To change this, modify the WATER_GOAL_L constant in hydra.py.

Data Storage

Water intake data is stored in data.json with the following structure:

{
    "YYYY-MM-DD": {
        "water_l": 1.5,
        "goal_l": 2.5,
        "full": false
    }
}

Each day is tracked separately, resetting the counter at midnight.

Plot

You can generate a plot of your progression by using:

python hydra.py --plot
