From 99c02d69db9ae03dda22378c287c876a8853fb7f Mon Sep 17 00:00:00 2001 From: Chip Hogg Date: Mon, 28 Oct 2024 11:55:18 -0400 Subject: [PATCH] Add forward declarations for individual units (#314) Individual `"au/units/*.hh"` files still pull in some decently heavy machinery. The sensible, scalable solution is to provide a `"au/units/*_fwd.hh"` file corresponding to each of them. Each "regular" units header will include its `_fwd.hh` header as the first include (and we add a comment to that effect to prevent clang-format from reordering them). Happily, this enables us to write a somewhat meaningful test for the forward declaraction machinery. We can now make a header file that provides an interface with only the forward declarations. Then we call that API inside of a test file. Finally, this is worth updating the docs for: - **Installation:** mention the `fwd.hh` files. - **Alternatives:** mention this feature, as we're the first units library I know of that provides it. All of these changes are in separate commits for the convenience of the reviewer: I recommend starting at the first, and using `n` and `p` to navigate them. Fixes #232. --- au/BUILD.bazel | 17 ++++++++ au/code/au/CMakeLists.txt | 55 ++++++++++++++++++++++++ au/code/au/fwd_test.cc | 29 +++++++++++++ au/code/au/fwd_test_lib.cc | 32 ++++++++++++++
