ed(1) conference @ed1conf@bsd.network

I got #linux 7.2 booting on my #Palm IIIxe and #Handspring #Visor! #nommu now to get my graffiti workalike working properly. (The stowaway keyboard works great for now. #ed is perfect on the 32x20 char fbcon) #busybox #buildroot. (See https://github.com/jsmemfault/uclinux)

@aartaka I tried ed(1) today and didn't hate it, what have you got me into!!

#ed

@svw
For some of us, it was a natural and desirable progression, without trauma, starting with ed, moving on to ex, and then getting access to a monitor (not a paper based terminal) and finding out that there was a visual screen based mode in ex, aka vi. :-)

Emacs came later.

My workshop at LRC on playing with UNIX V4 was a great success!

Everyone loved the teletype and terminal. In the manner of the day, I gave manuals to teach the system and ed (@ed1conf), and we now have a cohort of new ed users. A few groups solved or got close to solving my challenge of backporting the obfuscated mullender.c program from V7 to V4. Surprisingly with a dozen or so people on at once, UNIX handled the load fantastically.

If your IDE isn't shell job-control running ed(1) over a serial dial-up line into a BSD prod box with uptime measured in years, are you even programming?

So I wanted to share with you this little project of mine. I delved into "retro-necromancy" and reanimated one very old UNIX utility called ile written by Robert Pendleton in 1988. I found it on one of the Walnut Creek source code CDs from 1994.
What it does is simply works like an input line editor (hence ile) for shells and programs that do not support interactive line editing. To put it simply, it adds Emacs-style keybindings like ^A, ^E, ^K, ^U and so on and command history that you can easily navigate.
Of course, these days it's hard to find a shell that doesn't support line editing.
But this little tool can still be usable, for example, with ed. It's nice to have Emacs-style editing in ed.
It can work like shell replacement or just run like a "middleman" between any given program. It respects terminal settings and doesn't get in a way. Keybindings are configurable.
Needless to say, the code from 1988 wouldn't run on any modern system. It was written in K&R style because there was no ANSI C standard yet! And #UNIX was quite a different beast back then.
So I ported it to modern systems, rewrote outdated bits (like sgttyb ioctls and brutal utmp handling).
Currently it builds and runs on #Linux, #OpenBSD, #FreeBSD and #NetBSD. Hopefully without too much bugs.
You can find it on Codeberg:

inspired by @ed1conf I am going to try using only ed today.

(I can always come back to emacs using !emacsclient -nw if I really need to do so.)

Ok, this is funny...

I launched #tut with #vi as my default editor instead of #ed, because I just wanted to fire off a quick toot without having to put my brain in ed mode, and yet I kept...

Starting toots with a instead of o

Ending toots with \n.\nwq\n instead of [esc]:wq

Did I say VSCode? psyche!! I meant #ed, of course! 🤣
