*pokes blog*

Wow... that's a long time since the last update. Personally I blame Puzzle Quest (external link).

Lately I've been working on resurrecting the old parser generator I wrote for my honours project many years ago . It needed a few updates to bring it up to the current C++ spec, and since then I've been fixing up a few of the many little issues that make the difference between a prototype and a production system.

The main reason I started doing this is that I needed a frontend for the assembly encoder/decoder generator that I was (in turn) writing to support lxdream (external link) development. And to be perfectly honest, using yacc/lex is rather like pulling teeth after having had (the persistently inaccurately named) ELR[0] to play with. Plus, the grammar I had in mind pretty much required its automagic parser-state-based lexical-context abilities.

At the moment I'm tidying up a bunch of string and buffering issues in the skel code, and then I'll probably do a point release and get on with the assembly stuff for a while. It would be good to get elr to the point where it's a feasible replacement for yacc/lex for everyone though, so I'm certainly intending to get back to it in the future.

Oh, and in other somewhat out-of-date news we have a spoodle (external link) (don't blame me for the jacket...)


[0] It was originally intended to do both minimal-state LR(1), and EBNF - hence the name. I never had time during the original development phase though, but the name stuck nonetheless. Said features may make it in yet though, albeit probably not the first release version.

About me

Nathan is a full-time software engineer and part-time maintainer of several pieces of open-source software that noone has even heard of (most notably lxdream and elr). His interests include programming language design, distributed systems, emulation, Japanese, and go.
