Emacs was my first Lisp
interpreter
18/74

I learned a lot about language
implementation from Emacs

Then I got a Sparc Station

If I didn't like anything in
Emacs, I could change it

Emacs made me realize
anything can be changed by a
programmer

I could edit without thinking
key binding

I didn't want to write anything
without Emacs
34/74

so I wrote my own mail client

It was my first non-trivial
(Emacs) Lisp program
39/74

I used it everyday

It uses simple mark and
sweep garbage collector

Then I put Smalltalk-like OO
system on top
47/74

For syntax, I wanted Algol/Ada/
Eiffel like one

But as an Emacs addict,
I needed a language mode
49/74
Powered by Rabbit 0.9.2

Back in 1993, there was no
auto-indenting language
mode for a language with
such syntax
51/74

So I tried to write experimental
ruby-mode.el
52/74
Powered by Rabbit 0.9.2

I somehow succeeded to
implement auto-indentation
55/74

for a language with "end"
delimiters

If I couldn't make ruby-mode
to work
57/74
Powered by Rabbit 0.9.2

the syntax of Ruby would
have changed
58/74
Powered by Rabbit 0.9.2

too similar to other scripting
languages
60/74
Powered by Rabbit 0.9.2

as a result, Ruby would not
have gained current popularity
