00:08 <oni-on-ion> why cant dune just use ocaml itself

00:43 <oni-on-ion> it is not possible to use 'external' for native code ?

00:43 <oni-on-ion> using [@@unboxed]

00:44 <oni-on-ion> external calcMoney : float -> float = "calcMoney" [@@unboxed] [@@noalloc]

00:44 <oni-on-ion> "Error: The native code version of the primitive is mandatory when attributes [@untagged] or [@unboxed] are present"

00:45 <oni-on-ion> checking dune --verbose shows that ocamlc is used when the external is present, but ocamlopt when it is not. what is going on ?

02:30 <companion_cube> you have to provide 2 versions I think

02:30 <companion_cube> = "calcMoney" "calcMoneyUnboxed" or something like that

02:30 <companion_cube> (also, what do you mean "why can't dune just use ocaml itself", when it does?)

02:34 <oni-on-ion> (i meant that why dune has its own language, but its no matter =)

02:34 <companion_cube> ah, well, it makes it faster

02:35 <companion_cube> trading flexibility against convenience and speed

02:35 <oni-on-ion> true. i am also going to use sexp-scripts in my project

02:36 <oni-on-ion> also what i did for the moment is put more things into C -- because instead of unboxing individual values i can use bigarrays

02:36 <companion_cube> floats?

02:36 <oni-on-ion> yep

13:47 <amosbird> hmm, does ocaml have a decent lsp server now?

13:48 <amosbird> especially for find-references

14:04 <amosbird> https://github.com/ocaml/tuareg https://github.com/ocaml/caml-mode hmm, I cannot figure out the difference between the two

14:04 jmiven has joined #ocaml

14:05 <Drup> amosbird: if you are using emacs, just do `opam install user-setup` and follows the instructions

14:05 <Drup> it'll setup everything for you

14:06 <amosbird> yeah

14:06 <amosbird> I have emacs setup but it seems non trivial for working on a project like this https://github.com/moosotc/llpp

14:07 <Drup> this seems to have a .merlin file, so if you build once, it should be fine

14:08 <amosbird> well, caml-types-locate-type-file: No annotation file. Compile with option "-annot" or set 'caml-annot-dir'.

18:41 <Leonidas> oni-on-ion: There are build systems which are extensible in OCaml. My experience both in OCaml and in Python has been that this was way worse than an universal build system with agreed-upon defaults.

18:41 <oni-on-ion> i am going to have to agree with that
