Document command line arguments

[lobre]

I see that you parse 3 command line arguments in the main logic of vi: -s, -e and -v.

I am struggling to understand what they do exactly, and I can't find this info in the README either.

Do you mind explaining their meaning? And if so, does it make sense to document that in the README?

I saw you just added them with -h. Thank you!

Maybe I can suggest also to mention that a file can be provided.

vi [options] [file]

And as neatvi supports multiple buffers, maybe having it take multiple files as input could also be nice.

vi [options] [file ...]

I did not know that neatvi has ex mode. That is great.

Done.

As Neatvi does not support next and prev commands, I just added the first form. Ali

Would this make sense now that neatvi supports next and prev? (b+/b-)

These work for open buffers only. Argument list and next/prev commands are not supported yet. Thanks, Ali

I have just added a basic implementation prev/next. Ali

That is nice!

I am trying to open neatvi with some files filtered in a pipe with it seems neatvi does not like it though.

find | grep yml | xargs neatvi

It needs to read from the tty. Try this: ``` find | grep yml | xargs sh -c 'neatvi "$@" </dev/tty' ``` Ali

It needs to read from the tty.

Is there a technical reason why this is the case? What is blocking from having xargs working "normally"?

Programs like vi need the standard input to be a TTY. Please see the description of -o option in freebsd's xargs. Ali
