This is like putting NOS on a school bus.

JonnieCache• 14 years ago

That's ironic because it was written on a bus.

See the following rubycon talk, "worst idea ever!" which covers this and several other even more horrendously ill-advised gems:

http://www.confreaks.com/videos/198-rubyconf2009-worst-ideas...

It includes a way to rescue from segfaults, which goes quite nicely with the inline assembly :)

If you are a rubyist you should watch this. It's hilarious. If you think this wilson gem is crazy wait until you see the other shit they get up to.

Been doing something similar for Clojure:

Hats off to you! This is simply amazing!

I didn't write it. I just found it. Maybe should have mentioned that. But I thought it was clear. Sorry.

Cool. Looks similar to ronin: https://github.com/ronin-ruby/ronin-asm.

I'm curious if there are equivalent tools for doing this sort of thing for other cpu families. Specifically, what do people use for MIPS and ARM architectures?

sokrates• 14 years ago

What's different (from a quick look at ronin) is that this actually runs the assembled code within the currently running ruby interpreter. That's a lot more than a DSL for creating assembly.

My favorite thing about this library is that it parses the NASM manual: https://github.com/seattlerb/wilson/blob/master/lib/wilson.r...

You guys do understand this is a joke, right? It's a (cool) example of stupid things that you can get up to in ruby. See the ruby con talk for other examples. Enterprise Ruby is my personal favorite.

The rdoc for enterprise ruby is hilarious (https://github.com/tenderlove/enterprise#synopsis)

"Let’s convert that crappy ruby code to XML"

jrabone• 14 years ago

I don't think the community should be laughing too loudly about enterprise XML, given the security difficulties Rails has been having with its serialisation formats. How much did people lose in that Bitcoin exchange hack?

drv• 14 years ago

Pretty neat hack.

However, it's a bit odd that it parses the intended-for-humans NASM documentation instead of the machine-readable insns.dat that NASM actually uses to generate opcodes: http://repo.or.cz/w/nasm.git/blob/HEAD:/insns.dat

I wrote a similar thing a while ago for python:

http://www.grant-olson.net/python/pyasm

It even mapped all the exported symbols from the python API so you could do stuff like:

    CALL PySys_WriteStdout "Hello, World!\n\0"

About every three months I get an email from someone where I have to explain it was a proof-of-concept and never intended for production use.
