I’m pretty new to OCaml (on macOS). Currently getting into the ecosystem with development workflow.
Got a project setup properly now using dune.
Now since I’m a TDD’ler I’d like to run a Ounit2 test module right from Emacs instead of going to the terminal and type ‘dune test’.
(Is there a different way of doing this that I’m not aware of?)
So I thought I’ll simply create an Emacs minor mode that can do this for me with a key stroke.
The problem is that I can easily call ‘dune test’ via
(call-process ...) in Emacs but the process output says:
File "test/dune", line 3, characters 12-18: 3 | (libraries ounit2 lib)) ^^^^^^ Error: Library "ounit2" not found. Hint: try: dune external-lib-deps --missing @@default
Even though the ‘ounit2’ library is installed.
I’ve extended the exec-path in Emacs via
setq exec-path and the env PATH via
setenv in Emacs to include the path “~/.opam/default/bin”.
Now the question is why does ‘dune’ running through the Emacs shell process not see the installed libraries?
