A set of input modes that impact input operations is linked to every console input buffer.
Two categories of input modes can be distinguished: those affecting low-level input functions and those affecting high-level input functions.
Only applications utilizing the high-level output functions are impacted by the output modes.
The current output mode of a screen buffer or the current input mode of a console’s input buffer are reported by the GETCONSOLEMODE function.
The console input buffer or the screen buffer’s current mode can be set with the SETCONSOLEMODE function.
It should be anticipated by a command-line application that subsequent command-line applications might modify the console mode at any moment and might not return control to its initial state before then.
If the console is currently in full-screen mode, it is reported by the GETCONSOLEDISPLAYMODE function.
A compatibility feature called Legacy Console mode was created to assist Windows 10 users who still use outdated command-line utilities.
This mode offers a coarse-grained way to revert the system to an earlier version of the console hosting experience for any command-line tool that is not displaying or functioning properly in the standard Windows 10 console experience.
In order to enable as many users as possible to run the most recent version of the console, the Console Host team works to reduce the differences between the Legacy and current modes of the console.
Let’s investigate what Windows console mode is.
The Microsoft Windows console application infrastructure is called Windows Console.
Both an input buffer and a screen buffer are present in a Windows Console instance.
It makes console apps able to operate in hardware text mode or within a window.
The key combination Alt+↵ Enter can be used to switch between the two.
Windows Console instances are generally used by apps that may use color but do not require image display.
CMD.exe, Windows PowerShell, Far Manager, and Midnight Commander are a few examples.
Let’s investigate opening a console window.
Pressing CTRL+SHIFT+J (Windows, Linux) or COMMAND+OPTION+J (macOS) will open the CONSOLE the quickest.
Comparable to a sophisticated, feature-rich command line in DevTools, CONSOLE is an excellent tool to use in conjunction with other tools.
The following articles go into further detail about the various tasks that the CONSOLE tool can assist with.
- To determine why something in the ongoing project isn’t working, TRACK DOWN PROBLEMS. View Resolve JavaScript issues that the Console reports.
- ACCESS INFORMATION ABOUT THE WEB PROJECT as log messages in the browser. View the messages in Filter Console.
- In a REPL environment, TRY JAVASCRIPT EXPRESSIONS. View Launch the JavaScript console.
- USE JavaScript TO INTEACT WITH THE WEB PROJECT IN THE BROWSER. See Use the Console to Interact with the DOM.
We’ll discover what a console buffer is next.
A two-dimensional array of color and character data intended for output in a console window is called a screen buffer.
The buffer that is visible on the screen is the active one.
Every time a new console is created by the system, a screen buffer is created.
To add more screen buffers for its console, a process can use the CREATECONSOLESCREENBUFFER function.
A two-dimensional array of character information records is unique to each screen buffer.
Screen buffer size, text attributes, window size and location, cursor position, appearance, visibility, and output modes are among the attributes connected to a screen buffer.
Space characters are present in every position of a screen buffer when it is first created.
