@laurent22 Not really, except if you want to erase from your actual cursor to the end of line (eraseLineAfter()
).
More efficient: term.moveTo( 2 , 2 , ' ' ) ;
or term.moveTo( 2 , 2 , ' '.repeat( 2 ) ) ;
Also it could be interesting to have a higher-level function for erasing region, but it would definitively do something similar behind the scene.
What is your use-case? You may want to use the ScreenBuffer.

Great, thanks I missed that it was possible to do moveTo(x, y, chars)
.
A function like erase(x, y, width, height)
would be quite convienent. I can provide a pull request if you're interested?
Also another question, the insert(x)
function actually inserts space characters, is that right? Or does it take the character it's inserting from somewhere else? (It wasn't clear from the documentation)
Yes I had a look at ScreenBuffer but since what I want to do is quite custom (multiple scrollable lists and a text input below), I thought I'd try first with something lower level to have more flexibility. It's possible I'm reinventing the wheel though!

@laurent22 Hi, as you can see, I have added the .eraseArea( x , y , [width] , [height] )
method that does exactly what you want.
For the .insert()
method, it directly maps to a terminal capability. So I cannot tell you if it actually adds space characters, or if a terminal has an internal empty cell state. However since empty areas act as spaces when we copy/paste them, that's not really important.

Brilliant, thanks a lot for the eraseArea
function!
