The problem with compiling Ruby

Compiler technology is one of my hobbies, most recently satisfied with my project to write a series of post of how to write a (Ruby) compiler in Ruby. Since I really like Ruby, it's natural that I've done a fair amount of thinking about compiling Ruby, and what the problems ...

Writing a compiler in Ruby bottom up - Milestone: It can parse itself...

As always, if you don't know what I'm talking about, take a look at the series.

Writing a compiler in Ruby bottom up - step 14

Supporting variable length arguments

The C way handles variable length arguments is to let the caller push as much as they'd like onto the stack. It's then up to the callee to make sure they don't access too much, and there's really no way for the C function to know how ...

Just added a github repository for my compiler series

If you're following my compiler series you can now find a github repository here. For now I've just added the code published so far, but when I reach the end of the already written material I'll start making more fine grained commits.
Fork away :)


Writing a compiler in Ruby bottom up - step 13

It's been a few months, and apart from my side step into parser land I haven't had much time to keep posting this series, in part because of work, and part because of repeated illness that after being poked and prodded and x-rayed and being subjected to ultrasound (no, I'm not ...
