generate_natvis.py

Generate the Natvis debugger visualization file for all supported namespace combinations.

The ABI tag list and the library version are parsed from include/nlohmann/detail/abi_macros.hpp, so this script must be re-run (via make natvis) whenever an NLOHMANN_JSON_ABI_TAG_* macro is added to that file or the library version is bumped — otherwise the committed nlohmann_json.natvis drifts from the header it visualizes, and make check-amalgamation fails.

Usage

make natvis

or, equivalently:

./generate_natvis.py [--version X.Y.Z] [repository_root/]

--version and the output/repository-root directory both default to values derived from this script's own location, so they only need to be given explicitly when generating a Natvis file for a different checkout or a version other than the one in abi_macros.hpp.
