# HeurAMS - Heuristic Auxiliary Memorizing Scheduler

[中文](README_zh.md) | English

## Overview

HeurAMS "潜进" (Heuristic Auxiliary Memorizing Scheduler) is an auxiliary memorizing scheduler based on heuristic algorithms and cognitive science theories, designed to help users memorize and plan learning more efficiently.  
It is also an open, elegant, and extensible spaced repetition scheduler experiment platform, intended to help researchers conduct investigations, experiments, and research on cutting-edge memory algorithms more efficiently.

## Quick Start

### Installation

#### Install from Package Manager

HeurAMS (package name `heurams`) is in early development and not yet available on PyPI.  
However, you can install stable and development versions from the repository using pip, which requires a Python environment (Python 3.12.13 or later recommended).

Install from the stable `master` branch with optional dependencies for user experience (recommended):

```
pip install --upgrade 'heurams[basic] @ https://git.pluv27.top/pluv/HeurAMS/archive/master.zip'
```

Install from the more recent, roughly stable `dev` branch with optional dependencies (if you want cutting-edge improvements):

```
pip install --force-reinstall --no-deps 'heurams[basic] @ https://git.pluv27.top/pluv/HeurAMS/archive/dev.zip'
```

Install the general audio module for desktop computers (based on playsound3):\
(Not applicable for termux environments; termux has built-in audio support)

```
pip install --upgrade 'heurams[audio-playsound] @ https://git.pluv27.top/pluv/HeurAMS/archive/master.zip'
```

> You can also install from specific branches like `refactor/...` to test particular changes.

#### Install from Source

We provide two source installation methods: native Python and uv.  
See the [Contributing Guide - Setting up Development Environment](CONTRIBUTING.md#setting-up-development-environment) for details.

### Usage

Run `heurams` in your terminal, and you will see help information:

```plain
~ $ heurams
Usage: heurams [OPTIONS] COMMAND [ARGS]...

  HeurAMS 0.5.1 - Heuristic Auxiliary Memorizing Scheduler

Options:
  -v, --version  Show the version and exit.
  -h, --help     Show this message and exit.

Commands:
  help     Show this help message
  tui      Launch the built-in basic user interface (TUI)
  version  Print version information
```

Start the basic user interface by typing `heurams tui`:

```plain
~ $ heurams tui
Welcome to the basic user interface!
Loading config and context... Done! (2ms)
Loading UI framework... Done! (89ms)
Loading UI layout... Done! (56ms)
Component directory: <package directory>
Working directory: <working directory, ./data folder will be created here>
Pre-work total: 147ms

(Your terminal will now display the TUI)
```

Check the version with `heurams -v`:

```
~ $ heurams -v
