I assume you mean atdgen -v file.atd
. This produces file_v.mli
and file_v.ml
:
(* Auto-generated from "file.atd" *)
type json = Yojson.Safe.json
let validate_json = (
Yojson.Safe.validate_json
)
This is the correct behavior. It's just that Yojson.Safe.validate_json
doesn't exist. It seems to be the only thing that's missing.
The workaround (that I just found in our Esper codebase, yikes) is to create the following json module for yourself and reference it instead of Yojson.Safe
:
include Yojson.Safe
let validate_json _ _ = None
from atd.
I added validate_json
to Yojson.Safe
and siblings in yojson 1.3.0. ocaml-community/yojson@v1.2.3...v1.3.0
I think the reason why I didn't do it earlier was that I was fearing a mutual dependency. There's actually no problem since Yojson.Safe.validate_json
is polymorphic.

Thanks. I relied on exactly the same workaround :)
from atd.
In case it helps future seekers: the fix to Yojson was removed, see ocaml-community/yojson#136. So, iiuc, extending the Yojson.Safe
as per #97 (comment) is the way to do this now.
