What is the idiomatic/recommended way to interact with it from inside of an Ocaml program? At the moment, I have a code that works (I execute "ocamlmerlin" binary; I gather its stdandard output; I use "yojson" to parse this output; I traverse the JSON soup and find the pieces I want) but after finishing it, I is "unpretty". What should I do to make it more "pretty"? Is it absolutely necessary for me to deal with JSON instead of native Ocaml? Should I investigate a more seamless Ocaml/JSON mapping? (JSON may make sense in many scenarios, but in my cases, these are just two Ocaml programs talking). Or is there a way to cut JSON completely out of the interation and let my program talk to Merlin in Ocaml (and get back Ocaml values)? Concretely, if I have a question: Here is the file; here is the position of an identifier; where is it defined? I would get (e.g.) value of type (e.g.) "Lexing.position" instead of: { "class": "return", "notifications": [], "timing": { "error": 0.0, "ppx": 0.0, "query": 0.0, "reader": 0.0, "total": 0.0, "typer": 0.0 }, "value": { "file": "/some/absolute/path/to/test.ml", "pos": { "col": 0, "line": 2 } } } -- Caml-list mailing list.
