"Cannot find file down" from ocaml and utop
joprice opened this issue · comments
I can't seem to load down from dune's utop command or the ocaml toplevel. I'm using nix so perhaps dependencies for the toplevel are not where they're expected to be. I could probably symlink them elsewhere if I have to, but I'm not sure where toplevels search for their dependencies.
Here again I can't help you if you don't provide more details (context, exact sequence of steps you are performing and resulting errors). In any case down
is not made to be used by or in utop.
I wasn't sure what to provide as there's many components (ocaml, dune, nix, etc) so I started with the general question. I was able to make a little progress by removing the following calls from ~/.ocamlinit
let () =
try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH")
with Not_found -> ()
;;
and using #require "down";;
instead of #use "down.top";;
Not sure about the difference but this seems to work for me at least to try out down.

I general showing basic steps inputs/install commands, verbatim error messages and providing context (versions, stetup) is necessary to be of any help.
In that particular case it seems that the OCAML_TOPLEVEL_PATH
is not setup so that it finds where down.top
is installed.
You are now loading down
with ocamlfind
(require
is an ocamlfind directive) which should be fine. But down
is designed so that you can load it even if you don't have ocamlfind installed, by #use
ing down.top
