09:40 <salkin-mada> hello i am compeltely new to ocaml. i just set up my system using opam and dune. for my first project i want to use the OSC impl. so i did a opam install osc. all whent well. btw. i am on arch. in my dine init project. i am trying to use the send receive OSC example from the osc package. though this is meant for the REPL, hilevel thingy. #require bla bla. etc.

09:40 <salkin-mada> So in my nvim session i have the lsp and treesitter stuff going. seems to be ok.

09:40 <salkin-mada> but the question is really.

09:42 <salkin-mada> HOW to get the `require` to work? `require "osc.lwt" throws -- Unbound value require

09:43 <salkin-mada> or HOW to get the osc pack into my new dune initialized project. So that in the end of the day i can try these examples: https://github.com/johnelse/ocaml-osc

09:44 <salkin-mada> As you can tell this is al very new to me :) thanks for any help/pointers.

09:44 <octachron> require is for the REPL. In a dune project, you need to add the dependency to the dune entry for your library/executable with (libraries libname1 libname2)

09:51 <d_bot> <undu> dune needs metadata to define executable or libraries, a good tutorial to start with dune metadata is https://dune.readthedocs.io/en/stable/quick-start.html it explains how to add a dependency to an executable. In your caseyou can replace lwt with osc

09:51 <salkin-mada> ahh i seee. okay okay :) haha

09:51 <salkin-mada> thanks so much d_bot. really appreciate it.

09:53 <d_bot> <undu> people are happy to help here, we know starting with ocaml tooling is not the easiest thing ever 🙂

10:00 <salkin-mada> indeed :)

10:00 <salkin-mada> also thanks octachron :)~

12:55 <d_bot> <dj charlie> wish me luck peeps bringing ocaml into a mono go codebase

14:51 <olle> Cool

16:04 <olle> dj charlie, how did it go? :D

21:59 <salkin-mada> Hi again :) new to ocaml and dune here. I am trying to make a filetype mapping in vim which resemples what i do with .cpp(make), .cpp(pio), .rs, .lua, .scd etc. <C-e> is doing a simple `:terminal <build> and <run> && exit`. first part is fine with `dune build` but how to use `dune exec` ?? is `dune exec ./hello_world.exe` just a "shorthand" for `./_build/default/hello_world.exe` ? or how can i use `dune exec` without

21:59 <salkin-mada> specifying the `.exe` file.

22:00 <d_bot> <zseri> why is that message repeated 4 times?

22:00 <salkin-mada> ah sorry.

22:01 <salkin-mada> PEBCAK

22:01 <d_bot> <zseri> does `dune exec hello_world.exe` work?

22:02 <salkin-mada> nope. it gives me a hint - `./hello_world.exe`

22:03 <salkin-mada> what i am hoping to do is `dune build && dune exec && exit`

22:22 <salkin-mada> okay i see. `dune exec` needs a PROG specified.

22:24 <drakonis> use dune exec ./hello_world.exe instead

22:32 <salkin-mada> check. i was just puzzled by the fact that it looks like a *nix like shell `./this_file_exists_in_the_current_directory`<execute it> but the `hello_world.exe` is not in the root of the workspace/project so why use this "notation" for `dune exec` when the file is actually located in `./_build/default/hello_world.exe` why not just use `dune exec hello_world` - without the `./` and the `.exe` part. both seems to be

22:32 <salkin-mada> implicit.. or maybe there is something i am missing here :)~

22:52 <salkin-mada> okay this works nicely -> https://paste.rs/u6N.lua

23:03 <salkin-mada> is there any good source of OCaml example node which is not REPL based? Its a bit hard to understand how to structure a program when all the examples i find is with `#` and require etc. which i then learned is REPL only . including all the `;;`

23:04 <salkin-mada> ps. i've programmed in ocaml with dune actively for 30 mins. did a setup (up and running) earlier today.

23:06 <salkin-mada> so i guess i am on the lookout for good sources of learning material based around dune. besides the https://dune.readthedocs.io/en/latest/quick-start.html

23:08 <steenuil> if you're using dune you just have to keep all the modules you want to use in the same directory as the main one, you don't have to do anything to add files

23:09 <steenuil> that is you don't have to add anything to the dune file

23:10 <steenuil> also for learning resources, the new version of Real World OCaml seems to use dune and at chapter 4 it drops the repl

23:10 <salkin-mada> i see. okay. so i can dump ocaml packages/libraries directly in my project root or i can have dune do the work for me by populating the dune file with (libraries .1. .2. .3.).

23:11 <steenuil> oh, no if you want to use libraries you should definitely use opam to install them and then put them in (libraries ...)

23:11 <steenuil> *external libraries

23:12 <salkin-mada> yes. thats what i am doing for the ext libs . thanks - now gonna check this -> http://dev.realworldocaml.org/

23:43 <salkin-mada> i am trying the example from the `osc` package again.

23:44 <salkin-mada> and getting ->

23:44 <salkin-mada> Error: This expression has type Osc_lwt.Udp.Client.t Lwt.t

23:44 <salkin-mada> but an expression was expected of type Osc_lwt.Udp.Client.t

23:45 <salkin-mada> is something wrong with the package or am i misunderstanding how to use the REPL based example in non REPL way (lo level ocaml, i guess)

23:49 <salkin-mada> aha i see its me doing silly wrong things :)~

23:51 <salkin-mada> if an example says `require lwt.syntax` and uses `lwt` where you would expect a `let`. How would i go around and use that in a dune project?

23:51 <salkin-mada> i tried to (libraries lwt.syntax) but this is not recognized.

23:54 <salkin-mada> hehehe. sorry dont mean to spam this channel with my newbie .ml questions and thoughts. Will stop for now. But let me know is there is something OBVIOUS i a missing in regards to getting the "OSC send receive" example to work in a NON REPL project. straight up OCaml with dune. :]=

23:56 <salkin-mada> `open Lwt.Syntax` i guess
