Strider Uwe 🇺🇦🇨🇦🇲🇽First public update of #wile #scheme #compiler in a long time. I kept dorking around with what felt like small peripheral changes that didn’t merit an update, but over time it added up… there’s a pile of new stuff there, although not so much in the core of the compiler. Get wile 1.2.10 at https://github.com/uhollerbach/wile
Now, these are all captive strings, all the same length and all generated inside the library, so the sanity checks are really not crucial; if I can use string-ref-unsafe instead, I can gain, I dunno, 30% performance improvement. Well, I think now I can write string-ref-unsafe in a way that #wile can handle it, instead of having to dive down into pure C and doing it myself. Cool! 🤓
Dang… it’s been a couple of good evenings hacking on #wile #scheme #compiler. The latest bit was adding a way to add little snippets of C directly into what the compiler produces; very much a “here’s plenty of rope to hang yourself with, if you want to… enjoy!”. The reason for this was that in a fairly large regexp I was trying to process with the library I wrote, i found that string-ref was taking an inordinately large fraction of the time, in particular the bounds check.
I’m semi-pleased to announce that #wile #scheme #compiler 1.2.9 has landed at https://github.com/uhollerbach/wile… unfortunately life got in the way a bit this month. But here it is. This version changes the generated C a little bit to avoid some compilation failures due to incorrect scoping issues in said C code.
Also, because I could, I wrote a small quaternions module, for that slight air of 19th-century decay 😜
I’m pleased to announce #wile #scheme #compiler version 1.2.8 is available at https://github.com/uhollerbach/wile. This version handles (cond-expand) with embedded (defines), has further improvements in error messages, plus other small odds and ends. Still working on further improvements to new sequence handler aka “begin-new”, but the parts that work seem pretty solid.
Wasn’t quite the hacking session I wanted, I was trying to implement a bit of namespace management in #wile #scheme #compiler, and/but it is still generating some errors that I don’t fully understand. But… I was able to improve a number of error messages, and that’s never a bad thing.
Also sharpened some sanity checking, which promptly found a (fortunately trivial) bug in one spot in the runtime library 😱
Another fine hacking evening! A net loss of ten lines of code, plus one small tweak to another line, lets #wile pass all but one test; that one is a long-standing issue which I understand but don’t know how to fix well yet. #wile can’t quite recompile itself with this new code, but it’s getting very close…
