Hi DM,

I've noticed that when setting colors with ANSI ESC does, eg: ESC[1;32;40m and then calling bbs.nodesync(), that colors are being reset back to low intensity white.

Why isnt the color sticking?

eg:

-+- test.js
require("sbbsdefs.js", "K_NONE");

write('current white:');
write(' \x1b[1;32;40mXX BRIGHT GREEN:');
//write(' \1g\1hXX BRIGHT GREEN AGAIN:');
bbs.nodesync();
write('YY BRIGHT GREEN?:');
read = console.inkey(K_NONE,10000);
-+-

If I ";EXEC ?test", it shows XX BRIGHT GREEN correctly, but YY BRIGHT GREEN is not green.

If I uncomment the line using \1\g codes, it does stay green.

sync likely doesn't parse the ansi and doesn't know the color changed.

during nodesync it saves known color attributes first (in this case that would be whatever the state was before the injected ansi) and restores them afterwards, clobbering your changes.

the ctrl-a codes get parsed and do end up updating what sync thinks is the current color state.

This is "not the way". You should use Ctrl-A codes (or set console.attributes property) so that:
1. Synchronet knows what attributes you intended to set for the client and can restore them if/when needed
2. The code will work with non-ANSI terminals

Howdy,

This is "not the way". You should use Ctrl-A codes (or set console.attributes property) so that:

I guess I dont understand why there "is a way"? Nor do I understand why nodesync needs to modify the screen back to a state, I would have expected that be a task in console.* object if it was required at all?

The jsobjs.html implies that nodesync will only do something to the terminal (clear it), if an argument is given. Why does it need to send something to the terminal anyway, no argument is given?

Does it send the color change everytime its called, even if the resulting color change is already the current color being used by the terminal?

It might be helpful to update that description to include console state, since it is doing more than clear the terminal even without an argument.

Because Synchronet support multiple terminal types, not just ANSI.

Nor do I understand why
nodesync needs to modify the screen back to a state, I would have expected that be a task in console.* object if it was required at all?

nodesync() can display stuff to the screen (e.g. node messags/alerts/telegrams), so it wants to restore the "current" attribute after doing that. Sending a raw ANSI sequences changes the attribute on the terminal (well, "some" terminals) without informing Synchronet that's been done.

The jsobjs.html implies that nodesync will only do something to the terminal (clear it), if an argument is given. Why does it need to send something to the terminal anyway, no argument is given?

nodesync *can* display the messages I mentioned above in addition to time left, pending events warnings, etc.

Does it send the color change everytime its called, even if the resulting color change is already the current color being used by the terminal?

No.

Okay. The Baja SYNC function does the same thing, so that me helpful too: https://synchro.net/docs/baja.html

OK, makes sense.

No.

So if nodesync *doesnt* send anything to the terminal, why does it want to reset the current cursor color?

No.

Correction: for Synchronet versions before v3.21, the answer was "No", but with Deuce's terminal abstraction changes introduced in v3.21, that answer is unfortuantely, "Yes". So you may see a difference for your specific test between v3.20 and v3.21(e). I plan to fix that for future Synchronet builds/releases (revert to the v3.20 behavior).

OK, that explains it, thanks - because I was sure I didnt hit this issue previously, and I only got around to investigate why it was happening.
