[ANN] NegaPosi Compiler

SASADA Koichi

Hi,

I release NegaPosi Compiler 0.0.0+- on my diary page.
http://www.namikilab.tuat.ac.jp/~sasada/diary/20050...

NegaPosi is my new scripting language. Scripts written by NegaPosi
can run on ruby interpreter.

You can convert any Ruby scripts to NegaPosi scripts using NegaPosi
compiler.


Thanks,

Hahaha, I actually wrote one of these too, and was going to post it, but
darn it, you beat me to it :)

I think mine is simpler though ;)

P.S. I'll post it later, it isn't on my current machine.

If anyone is interested, here is my NegaPosi generator:

def generate_np(str, width=64)
(str+"\0").gsub(/./) do |b|
("%08b"%b[0]).tr('01','-+')
end.scan(/[-+]{#{width}}|[-+]+/) do |line|
puts line.reverse.ljust(width)+'_'
end
end

It can take a parameter to output different widths (which don't affect the
processing of the NegaPosi "code.") I took a more functional approach in
this, but I suspect SASADA Koichi's is more efficient.

Here's a (long) one-liner to do the same, taking advantage of
pack/unpack's "b" specifier:

str.scan(/.{1,8}/m).map{ |s| s.reverse
}.join.unpack('b*')[0].tr('01','-+').scan(/.{1,64}/).map{ |s| (s << ('
' * 64))[0,64]<< '_' }.join("\n")

OK, that *was* one line before I posted it. Let's try again:

str.scan(/.{1,8}/m).map{ |s| s.reverse }.
join.unpack('b*')[0].tr('01','-+').scan(/.{1,64}/).
map{ |s| (s << (' ' * 64))[0,64]<< '_' }.
join("\n")

I was somewhat scared that it would compile to yarv bytecode :)

Isn't NegaPosi going to be YARV's intermediate language?! ;-)
