#18222 new enhancement

BSD extensions to termios.c_cc

Description

We don't have support for VREPRINT, VWERASE and VLNEXT in termios. These are available in both BSD and glibc and provide some extra control characters to reprint the current line, erase a word, and escape the next character.

Extending the c_cc array would break existing apps, how should we go about that? Is it ok to do it for all non-gcc2 ABIs and rebuild all affected software?

What is motivation of adding it? Is it a part of official POSIX spec? Any important software need it?

It is needed by neovim. I'm just taking note here after a discussion on IRC with someone trying to compile that.

Not part of POSIX, I think the ticket title is pretty clear about that?

Is it possible to patch neovim to not use API extensions? Breaking ABI just for one program seems bad idea.
