Rust Todo List

This is a simple command line todo list app written in Rust as an exercise with specific goals in mind:

• Use a database to persist todos.
• Minimize the use of unwrap() and expect() calls.
• Include relevant working test cases, even if they are not 100% necessary.

The idea for this project was inspired by Top 15 Rust Projects To Elevate Your Skills and the suggested CLI todo app.

Available commands

Available commands:

    - add [TASK]
        Ads new task/s
        Example: todo add "Build a tree"

    - list
        Lists all tasks
        Example: todo list

    - toggle [ID]
        Toggles the status of a task (Done/Pending)
        Example: todo toggle 2

    - rm [ID]
        Removes a task
        Example: todo rm 4

    - sort
        Sorts completed and pending tasks

    - reset
        Deletes all tasks

Development commands:

# to run once
cargo run <command args>

# to run in watch mode
cargo watch -c -x "run -- <command args>"

# to run tests in watch mode
cargo watch -c -x test

Notes:

You need to install cargo-watch.

cargo install cargo-watch

The executable will attempt to create a directory called todo_db in your HOME or PROFILE folder, depending on the OS you are using.

This directory is used to store the SQLITE database.

Building

I use Linux, so building an executable means running

cargo build --release

There's also a convenience script called ./build.sh that builds and moves the executable to /usr/local/bin

Cross-Compile for Windows: Make sure you have the Rust target for Windows installed. You can do this with the following command:

rustup target add x86_64-pc-windows-gnu

Then, build your Rust project with the Windows target specified:

cargo build --release --target x86_64-pc-windows-gnu

After you build, copy the resulting executable into your path and run it:
