Description Stefan B. 2022-01-05 20:58:12 UTC

In the freebsd-hackers mailing list there was recently a discussion about bugs of vt.
At least another guy mentioned one of the most annoying vt bugs, so I think there is proof am not the only one who uses sc because of things like this issue:


Problem:
If one marks a line that goes across more than one screen line, vt *always* inserts a newline at each physical screen line end of the copy source.
This is highly annoying, as it is impossible to copy/paste in one piece, say, a command line.

Expected result:
The copied text gets pasted without newlines being inserted.

I just booted an old image I had around (12.0-CURRENT r327524) in QEMU, and sc behaves the same way.

This would be good to address nonetheless.

I cannot find the referenced report on hackers - could you please add a link to the mailing list archive? I want to make sure I'm correctly trying to reproduce the differing behaviour between sc and vt.

I re-verified and notice that on 13, sc indeed adds newlines at EOL, which should not be done.
Maybe I confused this with x terminal emulators, which behave well in this regard.

Anyway I agree with you that it would make sense to adapt the console behavior so it resembles the behavior one is accustomed with X terminal emulators.
