Avoid mutations in attribute parameters #29

Closed jmid closed 2 months ago

jmid commented 2 months ago

This fixes the first issue reported in #28.

The problem is that mutaml attempts to mutate the Boolean literal false in a type such as the below:

type some_type = A | B [@@deriving show {with_path = false}]

This is not compatible with the current architecture, which compiles - and hence preprocesses once, and then runs the resulting output repeatedly with different environment definitions.

There are 2 CI failures:

debian-12-4.14_ppc64_opam-2.2 which is known
debian-12-5.3~alpha1_opam-2.2 which is due to a 5.3-incompatible ppx_deriving https://github.com/ocaml/opam-repository/pull/26654

I'll merge
