Win32 Console -- Backspace to Last Line

开发者 https://www.devze.com 2023-02-20 12:45 出处:网络
I\'m writing a command interpreter like BASH, and a \\ followed by a newline implies a continuation of the input stream; how can I implement that in Win32?

I'm writing a command interpreter like BASH, and a \ followed by a newline implies a continuation of the input stream; how can I implement that in Win32?

If I use the console mode with ENABLE_LINE_INPUT, then the user can'开发者_StackOverflow社区t press backspace in order to go back to the previous line; Windows prevents him from doing so. But if I don't set ENABLE_LINE_INPUT, then I have to manually reposition the cursor, which is rather tedious given that (1) the user might have redirected the input stream, and that (2) it might be prone to race conditions, and I'd rather have Windows do it if I can.

Any way to have my newline and eat it too?


Edit:

If this would require undocumented CSRSS port requests, then I'm still interested!


Assuming you want this to run in a window, like command prompt does by default, rather than full screen, you could create a GUI application with a large textbox. Users would type into the textbox, and you could parse whatever was entered, and output to the same box (effectively emulated the Win32 Console).

This way whatever rules you want to set for how the console behaves is completely up to you.

I might be mistaken is saying this, but I believe that the Win32 Console from XP onward works exactly like this, and it just listens for output on stdout; there shouldn't be any reason you can't do the same.

Hope this was helpful.
