👉 Why use it

This framework provides many usful functions that abstract ACSI escape keys, allowing for easy implementation for a Terimal Interface.

• 🔢 Many features like key_press(), allows you to check a key without halting for a check.
• ⏱️ You can write Terimal GUIs much faster!
• 🖼️ Lots of functions allowing for more customizability, while keeping code readable and ideomatic.

📝 Example app

This is an example of using the framework, involving two key checks that don't halt the program twice.

clear(); // clear any debug logs
let mut app = App::new(); // store the variables relating to the terimal app

raw_line("q <- to quit"); // displays on a new line
raw_line("w <- to show lines"); // use only for startup text, relay on line method

raw_mode(true); // for propper input enable

// app loop
loop {
    clear(); // clear the screen, last loop, or Rust debug logs
    collect_presses(&mut app); // store the current key, in a variable for the loop

    if key_press(&app, "q") { // checks the stored current key, if it's "q"
        clear(); // clear the sceen
        break; // exits the terimal app
    }

    if key_press(&app, "w") {
        // displays First Sec, with Position struct
        // You can use position macro to shortten
        line(Position { x: 0, y: 5 }, "First", "blue");
        line(Position { x: 0, y: 11 }, "Sec", "red");
    }
}

raw_mode(false); // disable to release the user terimal

🧮 Core functions

App Struct

• Used to automatically hold variables outside the app loop.
• Holds the key buffer, from input and the key pressed for input checking in app. loop.

let mut app = App::new();

clear()

• Used to clear the screen.
• Tip: follow the structure in the later section of the Docs.

clear();

cursor_state()

• Used to toggle on and off the Cursor

cursor_state(false);

raw_mode()

• Used to enable raw input, which is required for most Terimal apps.
• Tip: Should toggled true before app loop, and toggled false after, to free the user.

raw_mode(true)

raw_line()

• displays on a new line before app loop
• Use only for startup text, relay on line method

raw_line("q <- to quit");

halt_press_check()

• Halts the program until the user has pressed a key
• will not be recored into app variable.
• So input will only be used for this if statement.

if halt_press_check(&mut app, "q") {
    break;
}

Position Struct

• Used as argument in many functions.
• Holds x and y position in the Terimal.
• X number of spaced words to the right
• Y number pf spaced workds Down
• Tip: You can use the position! macro to easly make a Position Structed

position!(0, 0)

collect_presses()

• collects the current press in a single halt, and stores it in App variable.
• Later inout statements refer to this value, to prevent unneeded halts, within the main loop for app.
• Used after clear, before any input if statements.

collect_presses(&mut app);

key_press()

• You must have one collect_presses() before at the start of the loop!
• Returns true if &str equals the last &str of input.

if key_press(&app, "q") { // checks the stored current key, if it's "q"
    clear(); // clear the sceen
    break; // exits the terimal app
}

key_press_not_case_sen()

• Refer to key_press(), for usage.
• Its the same, just not case sensitive.

if key_press(&app, "Q") { // checks the stored current key, if it's "q" or "Q"
    break; // exits the terimal app
}

How it works

🎨 Color Map

⌨️ Key Map

Most are directly named, q is q, and Q is Q

• Refer to find_key_pressed(), for more keys.

🏛️ Structure

1. clear, old text < optional clear()
2. setup app struct with new() let mut app = App::new();
3. Tip: this is a good place for raw lines to display exits or shortcut keys
4. set raw mode to true, with raw_mode() raw_mode(true);
5. loop {} - loops for each new input
6. Inside clear, for old text < optional clear()
7. collect_presses(), to store the current key pressed in app collect_presses(&mut app);
8. any if statements, like key_press() and code process if key_press(&app, "w")
9. Outside the loop
10. set raw mode to false, for exiting the app raw_mode(false);
