07:16 <discocaml> <peuk> Is there a standard way of getting the number of "cores" of the machine in OCaml?

07:17 <discocaml> <darrenldl> assuming you are asking in the context of ocaml 5, meaningfully this will give you the answer <https://v2.ocaml.org/releases/5.1/api/Domain.html#VALrecommended_domain_count>

07:18 <discocaml> <darrenldl> (if you are asking for the purpose of scheduling)

07:18 <discocaml> <darrenldl> if you are actually interested in the number of physical cores, i don't know off the top of my head

07:20 <discocaml> <peuk> Now, it is not related to OCaml 5. I have a program that starts external parallel processes. The number of processes is configurable, but I wanted to take as default the number of cores (physical or HT is not really important).

07:20 <discocaml> <peuk> No, it is not related to OCaml 5. I have a program that starts external parallel processes. The number of processes is configurable, but I wanted to take as default the number of cores (physical or HT is not really important).

07:21 <discocaml> <darrenldl> right gotcha

07:21 <discocaml> <darrenldl> linux? or you want cross os?

07:22 <discocaml> <peuk> Ideally cross OS, yup. This is why I hoped for a solution in the standard library.

07:22 <discocaml> <darrenldl> ah forgot about this completely <https://ocaml.org/p/cpu/2.0.0/doc/Cpu/index.html> - the creator uses it for their fork (and join?) library parany

07:23 <discocaml> <peuk> Oh, cool!

07:23 <discocaml> <peuk> Thanks

07:23 <discocaml> <darrenldl> standard library seems devoid of direct mentioning of core count, so that package might be your best bet

07:29 <discocaml> <peuk> Indeed

08:48 <reynir> I am curious how people keep ocaml ci happy: there is a library that has a (non-public) example binary that is not used in tests either. It depends on cmdliner which neither the library nor the tests depend on. CI runs build @install @check @runtest, and the dune build @check part tries to check the example binary.

08:50 <reynir> Now, dune build @check will fail if cmdliner is not installed. Do I add cmdliner as a dependency in the opam file? As a {with-test} dependency? Furthermore, the example binary only works with certain versions of cmdliner, so version constraints could propagate to dependent packages if they are installed with --with-test

11:54 <discocaml> <regularspatula> I have used a dev opam package for this sort of thing, if I understand you correctly

11:55 <discocaml> <andreypopp> hannes: @etiennemillon I was specifically interested in wireguard in userspace via ocaml

22:44 <discocaml> <nchu> Hi guys! I'm working with some of my classmates on this ocaml extension for vscode. We used menage to make bindings for ocaml -> js (for the extension) - We have created a seperate branch that includes raylib/bogue and we were wondering if it was possible to integrate our bogue with our vscode extension?
