Before this PR, we had a function to fetch the expansion for a directory:

Super_context.expander : dir:Path.Build.t -> Expander.t

The expander returned was incomplete however. In particular, it wasn't able to expand forms such as %{cma:..}. The end result is that whether forms such as %{cma:..} were expandable in a particular field in a dune file was basically random.

After this PR, we the expander returned by the function above is always able to expand these forms. So this makes the dune language both more powerful and more consistent.

Looks like a nice cleanup. LGTM, modulo a question (below).

Is this check as general as it could be? What happens if we write %{cma:../../../foo} in the test (so that we go way outside the root directory)?

I added a test - It doesn't go through.

By the way, there's still a way to do something illegal here. One can write:

%{cma:../another-context/foo}

And use the relative path to escape to another context. We should definitely forbid that as well. It's a much larger change though.

[new release] dune (15 packages) (3.15.0~alpha1)
68b4763 
CHANGES:

### Added

- Add link flags to to `ocamlmklib` for ctypes stubs (ocaml/dune#8784, @frejsoya)

- Remove some unnecessary limitations in the expansions of percent forms in
  install stanza. For example, the `%{env:..}` form can be used to select files
  to be installed. (ocaml/dune#10160, @rgrinberg)

- Allow artifact expansion percent forms (`%{cma:..}`, `%{cmo:..}`, etc.) in
  more contexts. Previously, they would be randomly forbidden in some fields.
  (ocaml/dune#10169, @rgrinberg)

- Allow `%{inline_tests}` in more contexts (ocaml/dune#10191, @rgrinberg)

- Remove limitations on percent forms in the `(enabled_if ..)` field of
  libraries (ocaml/dune#10250, @rgrinberg)

- Support dialects in `dune describe pp` (ocaml/dune#10283, @emillon)

- Allow defining executables or melange emit stanzas with the same name in the
  same folder under different contexts. (ocaml/dune#10220, @rgrinberg, @jchavarri)

### Fixed

- coq: Delay Coq rule setup checks so OCaml-only packages can build in hybrid
  Coq/OCaml projects when `coqc` is not present. Thanks to @vzaliva for the
  test case and report (ocaml/dune#9845, fixes ocaml/dune#9818, @rgrinberg, @ejgallego)

- Fix conditional source selection with `select` on `bigarray` in OCaml 5
  (ocaml/dune#10011, @moyodiallo)

- melange: fix inconsistency in virtual library implementation. Concrete
  modules within a virtual library can now refer to its virtual modules too
  (ocaml/dune#10051, fixes ocaml/dune#7104, @anmonteiro)

- melange: fix a bug that would cause stale `import` paths to be emitted when
  moving source files within `(include_subdirs ..)` (ocaml/dune#10286, fixes ocaml/dune#9190,
  @anmonteiro)

- Dune file formatting: output utf8 if input is correctly encoded (ocaml/dune#10113,
  fixes ocaml/dune#9728, @moyodiallo)

- Fix expanding dependencies and locks specified in the cram stanza.
  Previously, they would be installed in the context of the cram test, rather
  than the cram stanza itself (ocaml/dune#10165, @rgrinberg)

- Fix bug with `dune exec --watch` where the working directory would always be
  set to the project root rather than the directory where the command was run
  (ocaml/dune#10262, @gridbugs)

- Regression fix: sign executables that are promoted into the source tree
  (ocaml/dune#10263, fixes ocaml/dune#9272, @emillon)

- Fix crash when decoding dune-package for libraries with `(include_subdirs
  qualified)` (ocaml/dune#10269, fixes ocaml/dune#10264, @emillon)

### Changed

- Remove the `--react-to-insignificant-changes` option. (ocaml/dune#10083, @rgrinberg)
