Project setup 🏗️

Before you start programming, you must setup the project locally.

First, you will need to fork the Github repository, and clone it.

# Replace SkwalExe with your github username
git clone https://github.com/SkwalExe/rsfrac
cd rsfrac

Cargo is the Rust package manager.
If you need to install it, you can do so as follows on Linux systems:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

You can now start to make changes!

Running the app

Since Rsfrac uses a TUI (GUI-like interface but in the terminal) you cannot use simple println!() statements.

You will need to open 2 separate terminals. In the first one run touch rsfrac.log && tail -f rsfrac.log, and in the second one, run the app and add 2> rsfrac.log at the end of the command line (for example cargo run 2> rsfrac.log).

This will open the app while redirecting stderr to rsfrac.log, allowing you to send log messages to the first terminal. To log messages within the code, you must use the eprintln!() macro to print to stderr.

For example, this is what is looks like when adding eprintln!("..."); in the main loop:
