the standard JDK system input is buffered (ie. you only get the data when
the
user hits enter) - however, you can get non-buffered input in Linux by using
a
non-buffered input stream connected to a TTY set to cbreak mode

on Windows things are more tricky, hence the need for the extra native
lib...

How does tab completion have any clue that "bun<tab>" means "bundle " and

the shell TUI would configure JLine to do this

And how hard could it be to do such support directly in Shell TUI??


well, you'd need access to a non-echoing, non-buffering input otherwise
a) the user would see the tab and b) the shell wouldn't get the tab until
the user hit enter...

unfortunately getting this non-echoing, non-buffering input is non-trivial
and you'd probably end up duplicating a lot of JLine (or using script files)
