Last line received isn't displayed in connection window

[craigerl]

Hi guys, having fun with paracon!

I'm noticing the last line in a received block of text isn't displayed in a connected window.

In the following examples, a BBS displays a menu, followed by a prompt "=>" the prompt
is not displayed/flushed. If I press enter, the missing prompt appears, but the next prompt
doesn't.

the => prompt is not displayed, and isn't flushed until we receive more text.

This looks like a line gathering issue. Paracon collects incoming data and renders a line at a time when it sees a line end. It looks like URONode is perhaps assuming that the client will treat characters one at a time, rather than in lines.

So that I can look into this more deeply, it would be very helpful if you could do the following:

• Quit Paracon if it's running
• Delete your paracon.log file (saving it off first if you need to keep it)
• Manually edit your paracon.cfg file to add the following section:

  [Logging]
  level = DEBUG
  engine = True

• Start Paracon
• Go through the same steps you used to get the content in the screenshot above, and perhaps issue a command or two so that there's a little more data to work with.
• Quit Paracon
• Attach your paracon.log file to this issue.

This should let me see what's "on the wire", so to speak.

Be sure to remove the logging section from your paracon.cfg file when you're done, since it can quickly become quite large.

I see, from the screenshot, that you're running in a browser. I doubt that's going to have an effect, but it might be helpful to know the mechanism you're using, just in case.

right, i'll get that info. and i suspect you're right, there's probably no CR/LF after "=>" since it's a prompt.

edit: I'm using "ttyd" which is a golang terminal emulator that displays in a web browser.

I connected to a URO node, it prompted with =>, i typed "?" then it prompted again with =>

Just another illustration, we're not prompted to save our game in Zork! :) Real first world problem here!

[mfncooper]

Zork still exists? Whoa! I haven't seen that for many years.

Thanks for including the log. This is pretty much what I suspected was happening, though I'm a little surprised to see URONode sending the prompt in a separate packet.
