[9fans] Advances in software technology

[Nigel Roles]

I note from the article on the USACO programming contest in the
current Usenix magazine that one of chaps has written an implementation
of vi (the editor, not the mips simulator) in perl.

This is great news, as vi can now much more easily be ported
to other operating systems.

A much more usable solution would be to just implement BSD C library,
termcap, system calls and a C compiler in perl, so that anyone who needs
vi could just run perl and compile and run BSD vi on top of it. nvi is a good
program, after all.

So then rewriting perl in emacs lisp would make vi available
everywhere.

Actually, I've been reminded since that the latest versions
of vim have perl built in. Clearly, therefore, a perl implementation
of vim would actually be smaller.

# ls -l `which vim`
-rwxr-xr-x    1 root     root      1706824 Nov 21  2001 /usr/bin/vim*
                                   ^^^^^^^

Ouch!  But I still love it... :_)

somehow, the guy who wrote a flight simulator "in 1536 bytes of real code"
still remains my hero (ioccc's 98 contest, ioccc.org).

as for file sizes -- plan9's clock.c, which i modified slightly to compile
under plan9port yesterday, turned out to a binary of 2MB... at least it
occupies only 1.8MB ram :) go X!

but look at the upside:
$ ls -l `which vi`
lrwxrwxrwx    1 chesky   Users          18 May 17 14:58 /usr/bin/vi ->
vim.exe
                                        ^^

That still leaves room for improvement...

% ls -l `which vi`
lrwxr-xr-x    1 root     sys            2 Sep 26  1999 /usr/bin/vi -> ex*

Somebody was working on a rewrite of all the posix shell level tools in
perl, "in order to make them more portable" or some such drivel.  The
people in this world with too much time on their hands should be using it
on something really useful, instead!
