It always
seemed like it would have been just the thing to implement as a
tty streams module, but research Unix went in a different direction.
Not really. You want history files, I have one for each tty. Telling
the tty driver to write to this inode seems sort of weird. I guess you
could make it work, but to me, this screams libc or libhistory or
something like that. I agree it shouldn't be in each app that wants
it but isn't that what libraries are for?
That's why readline is a library, with application-specific hooks
available, and relies on something like rlwrap if you want to use editing
and history with an unmodified application.
