13:43 <discocaml_> <goodnight_noom> Is ocamllsp supposed to work out of the box in dune preview? I've just tried setting it up, but running `ocamllsp` gives `[ERROR] No switch is currently set. Please use 'opam switch' to set or install a switch`. (`~/.local/share/dune/env/env.zsh is sourced correctly`)

14:04 <discocaml_> <gooby_diatonic> Maybe ocamllsp is being run by a non-zsh shell

14:13 <discocaml_> <goodnight_noom> It is run by a zsh shell. I tried doing `eval $(opam env)` (which I thought would not be necessary with dune's preview?) and now I'm getting:

14:52 <discocaml_> <JM> You shouldn't run opam env with dune preview, it's more likely than not that your lsp install via opam is interfering with ocaml lsp from dune tools...

14:53 <discocaml_> <JM> There was a short conversation about lsp and dune preview yesterday in the #dune channel, you can have a look

16:06 <discocaml_> <aguluman> I had to downgrade some packages to enable ocaml and ocaml compiler to be on 5.3.0

18:20 <discocaml_> <nat.k> Forgive me if I've missed something silly, but I've tried updating to 5.3.0 to try out the new effect syntax, but I get this error

18:20 <discocaml_> <nat.k> ```

18:20 <discocaml_> <nat.k> Error: migration error: effect pattern is not supported before OCaml 5.03

18:20 <discocaml_> <nat.k> ```

18:20 <discocaml_> <nat.k> From everything I can tell (including `ocamlc --version`) I do have 5.3.0. Is there something in dune I need to change or something?

18:22 <discocaml_> <._null._> This is a PPX issue https://github.com/ocaml-ppx/ppxlib/issues/550

18:22 <discocaml_> <nat.k> Ah, thank you!

18:27 <discocaml_> <deepspacejohn> Good to know it's not just me!

18:29 <discocaml_> <nat.k> I shall add the sexy new syntax to my project another day then :-)
