- RTD (Rust To Do) is a todo app cli tool write by 500 lines Rust code. (exclude space lines/comments/long line break display/test code)

- RTD is also a [tutorial](https://github.com/cuppar/rtd/wiki), designed to learn Rust by doing.

## What can you learn from RTD?

#### Assuming you know nothing about Rust, through the [Learn Rust by 500 lines code](https://github.com/cuppar/rtd/wiki) tutorial, step by step to build the project from scratch, you will learn:

  - Rust common syntax

  - Rust module system (`package`/`binary crate`/`library crate`/`mod`/`pub`/`use`)

  - Rust ownership model (Bernstein conditions)

  - Rust lifetime

  - Rust error/null handling model (`Result`/`Option`)

  - Rust generic

  - Rust pattern matching (`if let` , `match` ...)

  - Rust unit test

  - Rust file I/O (`File Seek`/`Buffed File I/O`)

  - Rust manipulating environment variables

  - Rust command line parameter parsing

  - Rust release package to crate.io

  - The general process of developing a program (requirements/design/implementation/testing/release/maintenance)

  - Layered abstraction (data storage layer/model mapping layer/data model layer/business logic layer/application interface layer/user interface layer)

  - Handwritten serialization/deserialization from scratch

  - Implement the recycle bin function (virtualization concept)

###### Architecture

![rtd_arch](Tutorial/doc/img/readme/rtd_arch.svg)

###### Storage

Use a local file `$HOME/.rtd.csv` store all data

![data_storage](Tutorial/doc/img/readme/csv.png)

![rtd_list_all](Tutorial/doc/img/readme/rtd_list_all.png)

#### After completing this tutorial or installing RTD directly, you will get:

  - Extremely lightweight and concise todo command line application

  - Cross-platform, Rust's excellent build system naturally supports cross-platform

  - Safe, supports recycle bin, completely local, no network, no database

  - All data storage uses only one local csv file, which can be switched between different machines by copying the csv file

Interesting fact: I use RTD to complete the RTD tutorial :)

## Prepare

- Rust is naturally cross-platform. This project is built and tested in the `linux` environment, and `Windows`/`MacOS` are also supported. You can choose to download the corresponding `Cargo` according to your own operating system.

- `Cargo` Rust's package management and build tool, can be installed directly through the [Rust official website](https://www.rust-lang.org/tools/install) `rustup` one line command. Then, all things will be done by `Cargo`, so cute, right?

## Install

#### Via `crate.io` :

```bash

cargo install rtd-tutorial

```

#### Or via `git repo` :

```bash

git clone https://github.com/cuppar/rtd.git

cargo install --path rtd

```

## Usage

#### View help document

```bash
