08:49 <Ulrar> So if I have a text file I'd like to access as a string, is there a way to compile it in ? Instead of having to ship the text file with the final binary and read it at runtime

08:50 <engil> Ulrar: there's crunch as far as I know

08:50 <engil> https://github.com/mirage/ocaml-crunch

08:51 <engil> maybe for one text file it's a bit overkill

08:51 pierpal has joined #ocaml

08:52 tfunnell9 has joined #ocaml

08:53 <reynir> Ulrar: I like to use ppx_blob for that

08:54 <reynir> IIRC you write »let contents = [%blob "/path/to/file.txt"]«

08:58 pierpal has quit [Ping timeout: 240 seconds]

09:03 <Ulrar> engil: Interesting, overkill for this indeed but good to know it exists

09:03 <Ulrar> reynir: That sounds perfect, thanks !

09:08 <flux[m]> ooh, that's pretty nifty

09:11 <flux[m]> I wonder if OCaml's channels could be remodeled like how the Lwt_io has type 'mode channel type input type output.

09:12 <flux[m]> not sure how it does input+output channels, though :)

09:13 <flux[m]> would require using polymorphic variants I guess

12:09 <Leonidas> I think I have a weird bug with opam pinning

12:10 <Leonidas> https://travis-ci.org/issuu/ppx_mysql/jobs/429531094#L758 fails because it pins ppx_mysql to 0.1 but I never specify it to be 0.1 and expect it to be ~dev like it usually does

12:11 <Leonidas> the 0.1 seems to come from the extra repo, where ppx_mysql has a version 0.1 but why?

14:59 <Ulrar> Is there a way with dune to install the dependencies for a package ? Looks like there isn't

14:59 <Ulrar> Do I have to list the dependencies twice, once in the dune file and another in my ci to install the libs before running dune ?

15:02 <discord> <rgrinberg> Yes, dune isn't a package manager

15:02 <discord> <rgrinberg> But we are working on a mechanism to minimize this redundancy

15:03 <discord> <rgrinberg> use a package manager like opam or esy to actually install your deps

15:03 <Ulrar> didn't realize opam wasn't the only one

15:03 <Ulrar> Allright then, I'll write them twice, thanks

15:16 <Leonidas> Ulrar: well, it is the only one people use.

15:17 <Drup> Ulrar: ocaml-ci's script will automatically look in your opam file to find what to install

15:18 <Drup> so you don't need to write anything in your CI scripts, just in your opam file

15:24 <Ulrar> I don't have one, and I don't know ocaml-ci, but I'll take a look thanks

15:42 <companion_cube> is there a migration tool for moving files from jbuild->dune ?

18:48 <Ulrar> Drup: That looks like it's for travis, we don't use that. And it's not an opam package anyway really, just a tool for internal use so it looks like things like "test that your software can be correctly installed/removed completely by opam" won't make sense, our ci will generate .deb / .rpm / whatever packages for that anyway

18:49 <Ulrar> the tests part is interesting though

18:49 <Drup> Well, opam is also very nice for internal distribution

18:51 <Ulrar> We already have our repo on our client's servers, no need for anything else imho
