Terminal fixes#12369
Conversation
|
Pinging @zwim for review. |
|
Looks interesting, waiting for zwim. :-)
Could you name any examples? I didn't notice any slowness on my H2O in various programs I tried such as Elinks and Vim. |
|
@ziz57 I have just skimmed the changes so far. Can you give examples for which this PR is an imrovement? |
|
Mostly I was having problems with GNU Screen. It uses a lot of ^[K, so getting rid of the extra initTextBox there was the key change which fixed this for me. I also found the 300ms delay on enter rather annoying -- I hope there isn't some subtle reason why that was actually necessary. The other optimisations and fixes are things I tried/noticed while debugging this, and seemed worth doing. |

I would first unschedule and then close.

I think the unschedule first and then close still stands.

IIRC this cost me quite some time.
I have mainly tested the emulator with 'bash' 'vi' 'nano' 'shfm' 'watch' and the common bash commands.
One of them uses the ^[= and ^[> sequences.
Be aware the emulator is tested mostly with VT52 esc sequences. But at least one of the above programs (forgotten which one) uses VT100 sequences.
See https://espterm.github.io/docs/VT100%20escape%20codes.html -> VT100 in VT52 compatibility mode.

I would prefer
UIManager:nextTick(self.enter_callback)
here.

I would like it the other way round
for dummy = 1, n do
self.charlist[#self.charlist] = nil
Might be a bit faster and make the garbage collectors work a bit easier.

Hmm. Could it be that one of them was compiled for a different terminal?
This use of these sequences doesn't seem to part of VT100 or ANSI.
I would prefer
`UIManager:nextTick(self.enter_callback)`
Done.

Done.
By the way, after some more testing it seems I still have problems with
excessive cpu use by the terminal emulator in some cases... I'll try to
test more, and may submit another PR if I can figure out what's wrong.
Anyway, I think this one is finished.

@zwim I added one more fix, to the wrapping code; please review.
I'm also wondering what's going on with reverseLineFeed. It doesn't seem
to implement the vt52 specified behaviour. Is this for some sort of bug
compatibility, or should it be fixed?
Have you thought about better handling of double-width characters?

On Line 16 we have backspace defined (though is is Not an esc sequence).
You might want to use that (or even better defined it right and use it) ;)

@ziz57 You are Doing a good Job. Do you want to inherit this Code. I would Support you. |
It's the fourth time you tell us that. So, see you soon :) |

I don't know about inheriting it, but I guess I know it well enough now
that I can review changes. I'm also tempted to try to rework it to
handle wide characters, but we'll see.

Previous behaviour was to crash.
Fixes crash on e.g. closing widget after "sleep 3 && echo -e '\eY11'"
Required to maintain "tty-matrix".

Thanks; fixed.
I also added a @fixme to ReverseLineFeed.
Now it should really be ready to merge.

KOReader 2024.11 "Slang"  Some of you on Android may have had dictionary issues. That should be fixed now. Connecting to Wi-Fi should be more reliable on platforms where we manage it ourselves, most notably Kobo (koreader/lj-wpaclient#11). Color is now supported when reflowing (koreader#12085). This month's logo was contributed by @Sonnenfee We'd like to thank all contributors for their efforts.

Main effect is to make terminal usably fast with TUI programs which make extensive use of escape codes, which previously it wasn't (for me).
This change is
