Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime It is now August, 2014

...in one month, it will have been thirty one years

Why would anyone use a program that long?

Surely the state of the art has improved?

I learned Emacs in September, 1983

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime I don’t miss it one bit.

The OS I used was TOPS-20, on a DECSYSTEM-20

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime Some of you in this room weren’t even born in 1983.

So why the hell would I still use Emacs?

Crazy nostalgia aside, no one wants to use museum hardware.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime I only recently (temporarily) stopped reading Email in Emacs but I intend to ﬁx that. I keep my calendar and phonebook in Emacs (though I want better integration with OS tools). I do all my development work in Emacs. I (sometimes) use IRC/ICB/etc. in Emacs. I wrote this presentation in Emacs (it’s LATEX). I wish I could browse the web and read papers in Emacs, maybe that can be ﬁxed too.

In fact, I don’t just use Emacs, I live in Emacs.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime I am not the only one, either.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime Another PhD Student at U. Penn said to me:

I don’t care about the OS I use, it is just a boot loader for Emacs anyway.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime If you take CIS-500 at Penn, you’ll watch the professor run Coq from within Proof General Mode in Emacs.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime My “normal” non-programmer friend Ian uses Emacs for his calendar, email, to-do lists, practically everything.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime I gave the original version to the Emacs Club at Penn!

Sure, there’s a lot of weird people in any CS department, but there’s an Emacs Club. There’s an Emacs Meetup here in a city not lacking for forms of entertainment.

That implies fanaticism.

Heck, I’m giving this talk to the Emacs Meetup.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime WHY?

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime Those of you who use it every day know the learning curve is (ridiculously) steep.

Is it because Emacs is so easy to learn?

Natural Selection

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime In the beginning was the Teletype

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime Late 1960s: Glass TTYs appear. They save paper.

By Mid-1970s: Commercial terminals with positional cursor control.

(1975: VT-52)

Teletypes mean line editors.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime Emacs and vi are the sole survivors.

We expect they survived because they were better.

Were the designers lucky or smart?

Can we know? Does it matter?

At least hundreds of screen editors created were created in the mid-to-late 1970s.

Perry E. Metzger [email protected] Emacs: The Editor of a Lifetime Computer scientists do just two things: ...reading text ...and generating it. No one pays us to read if we don’t write afterwards.
