[Reposting so it will show up at the top of Planet Lisp]
Greetings FSet users,
For several years I was too busy to do much with Common Lisp, but having left my last job a few months ago, I am now working on a project in CL. I'm using FSet, of course, and so I've been reminded that it needed some TLC; there were some bugs to fix, and the documentation was very old and possibly hard to find. So I've put some time into it and prepared a new release.
The first thing I did was to review all the commits Paul Dietz made back in 2020. These were more extensive than I had realized; he greatly expanded the test suite and fixed a number of bugs. I have tried to thank him for his work, but he seems to have retired from GrammaTech; I have not been able to reach him. If anyone is in touch with him. please convey my thanks.
One bug Paul noticed but didn't fix, probably because he thought someone might be depending on the current behavior, was that compare on maps and seqs was not comparing the default; if two maps or seqs had the same contents but different defaults, they would nonetheless be reported as equal. There is indeed a chance of breaking existing code by fixing this, but I think it's small; in any case, I've decided to risk it — the behavior was clearly a bug.
The only other possibly breaking change I've made is to revamp the APIs of list-relation and query-registry. I wrote these classes some time ago, specifically for the project I was working on (and have now resumed); they're not well documented, and I'll be surprised if anyone is using them, especially in the case of query-registry. If I'm wrong and you are using them. post a comment and I'll explain how to convert your code, if it's not obvious. (I did remove some methods from query-registry that I was no longer using; I can restore them if necessary.)
I've also collected the FSet documentation into one place, and freshened it a little.
As part of this work I have also updated Misc-Extensions, which contains some macros that I like to use (and are used in FSet). In particular, I made some improvements to GMap, my iteration macro (we all have our own iteration macros, right?), and wrote a README for the system, that should make it a lot easier for people to see what's in it.
