Thank you!

There do seem to be some indentation issues. Have you seen the 
section "Formatting Code" in the Guix manual? There is also a 
little script in the guix repository that will automatically 
indent a package definition.

Also your commit logs don't seem to be exactly in the required 
format. For example: "gnu: add ocaml-ppxlib" should be "gnu: Add 
ocaml-ppxlib.". Check the section "Submitting Patches" in the Guix 
manual and also the commit history for examples.

There are also some things that the linter discovers. For example 
you can omit the ".git" suffix for GitHub sources or that 
pkg-config is not needed in ocaml-graphics. You can run `git lint 
PACKAGE` too see what the linter has to say (and maybe should do 
that for modified package definitions).

> , but also how to make non-4.07 packages

This looks ok.

I submitted a series of patches that does this for many OCaml 
packages including the ones included in your series 
(https://issues.guix.gnu.org/47768). I'm sorry I should have 
included your work in my patch series instead of duplicating.

Maybe a small difference is that the patches in #47769 include a 
more recent version of ocaml-ppxlib (and the required version of 
ocaml-migrate-parsetree).

I have updated your patches for ocaml-graphics and js_of_ocaml so 
that they can be applied on #47769. Some changes in the attached 
patches:

ocaml-graphics:
- Use version 5.1.1 instead of 5.1.0 (5.1.1 was released after you 
  submitted the patches)
- Remove unnecessary inputs
- Change git-reference url to homepage (GitHub without the ".git" 
  suffix)
- Minor changes to description too make linter happy

ocaml-js-of-ocaml:
- Set home-page to https://ocsigen.org/js_of_ocaml/
- Use version 3.9.0 instead of 3.8.0 (again released after you 
  submitted the patches)
- Enable source maps by including ocaml-yojson as input
- Enable tests (this requires ocaml-ppx-expect, 
  ocaml-ppx-variants-conv, ocaml-variantslib and an updated 
  version of ocaml-num)
