// Copyright 2021 Foxcirc. // // Licensed under he MIT license: https://opensource.org/licenses/MIT //! Create multiple consoles for a **windows** application. //! //! This crate makes use of windows Named Pipes to enable a process //! to controll multiple consoles. //! //! # Quick Overview //! //! Normaly a program running on windows can only use one console. //! > A process can be associated with only one console, so the AllocConsole //! > function fails if the calling process already has a console. //! //! _From the [microsoft docs]._ //! //! This crate solves this problem by providing an abstraction over a worker process //! wich is controlled using named pipes. //! //! # Examples //! //! You can use the [`Console`] class to create a new console, after that //! you can write to it or read a line. //! It is planned, that [`Console`] will also implement the `Read` and `Write` traits. //! //! ```rust //! use pipedconsole::Console; //! //! let my_console = Console::new("My Console").expect("Failed to create a new console"); //! my_console.println("What is your name?"); // seperate window //! //! let mut name = String::new(); //! my_console.read_line(&mut name).expect("Could not read from the console"); //! println!("Your name is: {}", name); // main processe's console //! ``` //! When the console object is dropped or the calling program exits, the console //! will close automaticly, unless another process also writes to it. //! //! # Important //! This crate comes with a build script wich tries to compile the `console_worker` executable. //! You need to have the `cargo` command usable in order for it to work. //! This script is important because cargo does not build binaries inside library crates, so //! it needs to be done manually. //! //! If the build script runs for the first time, it will display an info message. //! //! When you run your program, a call to `Console::new` will do the following: //! //! 1. It trys to find the `console_worker` executable **in the same directory** as the currently running one. //! This will always work, if you put `console_worker.exe` into the same folder as any executable calling Console::new(). //! 2. If it cant find the executable, it tries to find it at the default path cargo will put it when you build normally. //! This only works inside the default cargo project structure and makes it easier to just use this crate as-is. //! //! If you want to move your executable and run it in a new directory because of some reason, //! you will have to find `console_worker.exe` on your computer. //! For more information on where you can find it, run the build script again with the `PIPED_CONSOLE_HELP` //! environment variable set. //! //! If you use `cmd`: //! //! ``` //! set PIPED_CONSOLE_HELP=TRUE //! cargo clean //! cargo build //! ``` //! //! This should display a message on where the `console_worker` executable is located. //! //! # Additional Information //! //! Creating a new [`Console`] **will create a new seperate process**. That means you will //! see a "console_worker" process in your task manager. That process is just the console //! listening for commands to execute. //! //! In order to interface to a console-worker process using another language etc. you can //! manually launch it and then connect to the named pipe wich is created. For more //! information about this see the `worker` documentation inside the repository. //! You can find the worker binary files at `/src/bin/console_worker/main.rs` //! //!
