The git repository is still at <http://git.ageinghacker.net/jitter> . — Luca Saiu, 2021-12-19 19:52 [...] Read more

Introducing Jitter, an efficient language Virtual Machine generator — 2017-08-31 04:18 Updated: 2017-09-03 14:05

During the last few months of this long silence I’ve been busy working on a new project. Of course it is free software, and I plan to propose it soon as an official GNU project. I’m now releasing Jitter to the public, after presenting it for the first time at the 2017 GNU Hackers’ Meeting (<http://www.gnu.org/ghm>) in Germany last weekend. The meeting, by the way, was awesome — thanks to the organizers John Darrington and Alex Sassmannshausen and to everybody who attended. I was good to see the old friends, and make some new ones as well. The Jitter presentation [...] Read more

A practical GNU epsilon tutorial Audience Lexical conventions Rationale and introduction My PhD thesis Implementation, and the relation beteen epsilon0 and epsilon1 The bootstrap problem Setup Writing more comfortably, from ‘guile+whatever’ and Emacs Basics of epsilon1 The stuff values are made of: fixnums, pointers, buffers Error situations in epsilon1 Slightly higher-level data structures: vectors, strings, boxes, tuples, records Equality and boxedness tags Lists, and simple programming examples Digression: a look at epsilon0 Practical programming in epsilon1 Sums A programming example: structural equality with boxedness tags A look at reflective data structures ‘e1:define’ is just a macro! S-expressions What’s the point [...] Read more

Meta-update and GNU epsilon news — 2012-08-29 23:33 Updated: 2012-09-16 13:38

This little diary of mine needed some love. A good excuse to motivate myself to write more often comes from the idea of syndication in the GNU Planet (<http://planet.gnu.org>); to make that possible without adding off-topic stuff to the GNU site I’ve recently improved trivalblog to also support per-tag RSS and Atom feeds — the idea being, of course, to have only posts explicitly tagged as “gnu” linked from the planet. My little blog system is described in The trivialblog software (<https://blog.ageinghacker.net/posts/2>). It’s just a quick unpolished hack with no documentation built upon bash and Texinfo, but I find it [...] Read more
