       Play-enjoy[with command-line and LilyPond]   






    If you are new to LilyPond, I recommend getting familiar with it using "copilot" on Windows OS.
            However, I think the "ly-code (example of manuscript file description)" is an example using lilypond version "2.26.0".


    If you're not using a text editor.
    Use a Word Processor!!    Write LilyPond code (musical expression) in LibreOffice/OpenOffice.



    cf;         If this is your first time using HTML,
            HTML Tutorial!!            Easy Learning with HTML   Click on "Try it Yourself"(just below the example)

    cf;
    More than the installation method described on this page.
    Whether you're using a Windows OS environment or a WSL-setting environment,
    if you ask "Copilot" about installing LilyPond, TeXLive, etc., they'll give you perfect instructions.
    ---- I recommend it (more than explanations from others or elsewhere). ----

    Special Installation; From "install-tl-unx.tar.gz"
    !! "install-tl-unx.tar.gz" will not run unless it is the latest veersion.
    !! Unpack and
        install-tl-YYYYMMDD$ sudo ./install-tl -no-gui[Enter].

    You can use multiple of these. Windows OS(wsl)-----Debian Linux(wsl)----Ubuntu-26.04 You will need the same files—such as install-tl-unx.tar.gz and lilypond-2.26.0-linux-x86_64.tar.gz—for each environment.



    You can learn how to manage multiple Linux instances by using "Copilot" , and >wsl --help[Entr](on Windows OS).


    Under the Linux(wsl)----Ubuntu-26.04 amd Windows OS(wsl)-----Debian environment,
    For example, executing the following commands On Windows OS(wsl)-----Debian   cmd.exe---->wsl.exe --terminate Debian[Enter] and
      cmd.exe---- >wsl.exe --set-default Ubuntu-26.04[Enter]
    switches the environment from Debian to Ubuntu-26.04.

    Oh! The AI ​​has given up? AI says; Based on the information provided, it is not possible to determine the next value.!!


    But, I won on my fourth try.! ----Anyone can guess it after 5 or 6 tries!!
    Play-enjoy "Random number estimation"(guess)[with command-line]  On wsl(linux)         As you can see, this is written in Rust.
    [picture]
    This is the fourth time a random number has been generated (the random number is generated using a setting of one of the numbers from 1 to 10).
    Download: executable file=====>yukio     To execute, use $ ./yukio[Enter]($ mv yukio any-name .... OK)
                                  This "yukio" will run even without a Rust.



    This is the source code.,
    file-name;; main.rs      copy; ===> 
    use std::io;
use rand::Rng;
use std::cmp::Ordering;


fn main() {
    println!("Guess the game !");
    
    let secret_number = rand::thread_rng() . gen_range(1..11);
    
	println!("Please input your guess.  ---Choose a number from 1 to 10. ---");
	
	let mut guess = String::new();
    	io::stdin()
       .read_line(&mut guess)
       .expect("Faild to read line");
    
    let guess: u32 = guess . trim() . parse()
         .expect("Please type a number !");
        
    println!("You guessed: {}" , guess);

    match guess . cmp(&secret_number) {
        Ordering::Less => println!("I'm sorry to say.     It's small!
                                                     The secret number is: {}" , secret_number),
        Ordering::Greater => println!("I'm afraid to say.       It's big!
                                                          The secret number is: {}" , secret_number),
        Ordering::Equal => println!("You wini"),
    }
}
    		         For example;
    $ cargo new yukio[Enter]
    $ cd yukio[Enter]
    yukio$ src/main.rs<===Write the code within the left frame.
    yukio$ Cargo.toml<===Add to the last line. (rand ="0.8.3" )
            [package]
            name = "yukio"
            version = "0.1.0"
            edition = "2024"

            [dependencies]
            rand ="0.8.3"

    yukio$ cargo run[Enter]   running ...OK
    yukio$ target\debug\yukio[Enter]   above (WSL).
    cf; If you're starting with rand ="0.9.0", etc., leave it as rand ="0.8.3" and build again with
       $ cargo build[Enter]
    or .......... for example;
    let secret_number = rand::thread_rng() . gen_range(1..11); <=== rand ="0.8.3"
    let secret_number = rand::rng() . random_range(1..11); <=== rand = "0.9.0"
    .....rewrite.


    If you're using ;Windows OS(Rust-environment),
    Install rustup on Windows.---Quick way: Install Rust on WindowsOS(x64);---

    1) Install (Visual Studio)
          https://www.rust-lang.org/tools/install <======= on the screen.
       ||DOWNLOAD RUSTUP-INIT.EXE(32-BIT)|    ||DOWNLOAD RUSTUP-INIT.EXE(X64)||    ||DOWNLOAD RUSTUP-INIT.EXE(ARM64)||
      Select (x64); click====>Download//However, this is Visual Studio to link Visual Studio with Rust.
    (Windows OS-Folder); Downloads/rustup-init.exe <====Click
    Select 1).　>1[Enter] =====>this is Visual Studio to link Visual Studio with Rust.
    Launch after installation; do not check the box. ..........Why? Because,
    If you're not a programmer (like me), you can just close everything once the installation of Visual Studio is finished.

    2) Installing Rust for Windows OS
    (cmd.exe)> winget install Rustlang.Rustup[Enter]
    After installation is complete.[Here's my example.]
    (cmd.exe)>rustc --version[Enter] =====>rustc 1.99.1 (58cf8f9c3 2026-10-13)
    (cmd.exe)>cargo --version[Enter] =====>cargo 1.99.1 (5f94df478 2026-08-27)
    If these are displayed, it's OK!! (The Visual Studio and Rust connection setting is already set to 1).

    The installation order of steps 1) and 2) is not strictly necessary; step 2) can be done first. If Visual Studio is already installed,
    performing steps 2) and 1) in that order will result in Visual Studio (+Rust) being installed in step 1).

    Refer to the above "This is the source code." and execute...
    >cargo new yukio[Enter]   >cd yukio[Enter]    yukio>src/main.rs<===Write the code within the left frame.    yukio>Cargo.toml<===Add to the last line. (rand ="0.8.3" )
    yukio>cargo run ......OK .......yukio>target\debug\yukio.exe[Enter](Same as the WSL display above)
              This "yukio.exe" will also run on Windows PCs without a Rust environment.[wsl(linux): Same as "yukio"]

    Play-enjoy; (guess). Now to the main topic.--- wsl(Linux), Windows ---
    For the actual main.rs in guessing, please refer to the pdf Book.   "Chapter 2 Programming a Guessing Game" contains the actual "main.rs" code.
    The actual code is: " let secret_number = rand::thread_rng() . gen_range(1..101); " and is written using the " loop " function.
