Feature Request: deletion of echos

[Vadi]

I tried this a while back and couldn't get any combination of voodoo to work - being being able to delete echo'd text is quite necessary. For example, I'm starting to make use of click-based menus that are rendered with the magic of echoLink - and re-rendering them by re-displaying them and thus filling up players buffer with past renders isn't a nice thing to do. Being able to wipe the old menu and re-render the new one in the same spot would be much better.

I need a screenshot to understand what you mean.

Here is a video demonstrating the issue. Ideally, the menu would be changed in-place - but because it can't be, right now it spams the buffer with each render.

The only way I've really been able to do anything like this of value has been with miniconsoles, which aren't ideal sometimes.

Oh... thanks for the idea. I was being stupid by not even thinking that way.

Oh... thanks for the idea. I was being stupid by not even thinking that way.

Hehe, sarcasm or actual thanks?

[Vadi]

Oh that was not sarcasm... Heh, please don't take it that way. I think I can come up with something nice there, ill post the results.

[tsuujin]

Oh, check it out, you can delete cechos.

Code: [show] | [select all] lua

cecho("\n<white>First line")
cecho("\n<red>Second line")
cecho("\n<blue>Third line")
cecho("\n<green>Fourth line")

moveCursor("main",0,getLineCount()-1)
deleteLine()
moveCursorEnd()

[Vadi]

Seems to work, thank you! Will see about implementing into my menus sometime, see how that works... I think properly defining the compacting order of lines from deleteLine() in the manual would be something to do as well.
