clearing or capturing the screen

[Slack]

I wish to write a console text editor. Can anyone tell me how to
capture the screen like Vi or Pico does?

Also, I wish to draw "tabs" on the screen, is there a standard way to
draw so that my code is crossplatform and will compile on most
platforms?

Thanks,

Hi,

I take it that you are developing for *nix systems then I believe you have
to take a look into ncurses. I believe that is a library that let you
position the cursor clear terminal screen etc.

I don not believe vi captures the screen rather (like on windows) it knows
what is on the screen internally and redraws parts (give commands to the
terminal) if those change.

The standard C++ language itself has no support for 'manipulating'
the console window and its inputs/outputs. A platform-specific
solution is therefore required.

However, you can use a library that is available on most platforms.
I think 'ncurses' is included on most unices, and is available
on Windows as well. Try googling for that.
