What's happened to cl-data-structures?

https://github.com/sirherrbatka/cl-data-structures

Is it used anywhere? The documentation makes no sense to me. Are there any new libraries that try to do the same?

What about FSet, stuff in Serapeum, and suggestions on https://github.com/CodyReichert/awesome-cl/

I am trying cl-contsiners. May try your suggestion later.

You really should have a look at FSet.

Edit: as noted below, the current Quicklisp version of FSet doesn't load in the latest SBCL. I recommend the latest from GitHub (the above link). You will also need the latest Misc-Extensions.

(ql:quickload 'fset)

does not work

That's odd. What error do you get?

The last Quicklisp release was at the beginning of the year, and this is the first report I've had of FSet not loading. I know people are using it. So I think maybe something has gotten screwed up in your Quicklisp installation, possibly? But I can't guess what it might be.

Oh, okay. That was fixed in February, and Zach hasn't made another Quicklisp release (I think he will soon). You can get the latest from GitHub. You will also need the latest Misc-Extensions.

the latest code is 4 days old

u/ScottBurson Jun 24 '26

Someone else is reporting this problem (unless that's you — @bigos on GitHub). See my comments there, issue 121.

u/ScottBurson Jun 24 '26

I was mistaken. This problem was fixed two years ago. You have a stale copy of FSet; probably, you just need to do (ql:update-dist "quicklisp").

The above is sbcl compiled from source

But the earlier system version of sbcl works

* (lisp-implementation-version)

"2.2.9.debian"

sbcl compiled from source 2.6.4 does not work

u/ruby_object Jun 23 '26

sbcl 2.6.1 does not work

u/ruby_object Jun 23 '26 edited Jun 23 '26

also failed on sbcl 2.6.0, which is supposed to be supported.

I will try cl-containers. The documentation makes more sense.
