Add property checker/metadata system #166
Conversation
* include/ofx-props.yml is the property reference/metadata * scripts/gen-props.py is the checker and source generator All props are included in the YML definition, and the script generates C++ files with all the property metadata and suite assignments.

Also include them into prop tester plugin, to test whether they compile properly. TODO: prop tester should use the metadata to do better tests. Signed-off-by: Gary Oberbrunner <[email protected]>

Since this it auto generated, you could consider std::array<struct PropsMetadata, N=FeedByScrip>.
If this header is intended to be use more C++, you should consider having this std::array as constexpr.
maybe:
#if defined(__cplusplus)
#define CONST_SPECIFIER constexpr
#else
#define CONST_SPECIFIER const
#endif

Thanks @abizeauMaxon -- totally agreed. As per discussion at the TSC today, I've moved these into Support/include and they are 100% C++. I used fixed-size std::arrays where possible, as well as some other updates and cleanups. More feedback will be helpful; let me know if you try it out.

You should be consistant, if you use std::string for name, you should also use std::vector<std::string>

I've tried now to move to char *, to avoid allocations where possible during startup. I should move to std::string_view in some places. I'll do that.

again, here you should consider consistency, pick std::string or const char*

Is this auto generated? If so maybe add it into the header

ofx-props.yml is hand-created -- it's now the source of truth for all info about properties and property sets. That's the lion's share of the work in this PR (and probably the source of remaining bugs, where I may have gotten some stuff wrong). None of this info was machine-readable before, so I extracted it from the docs and header file comments.

The strings are the true spec, not the #define names. This also adds a set of static_assert tests to ensure the #define names match their strings. But doing this brought up that there are some mismatches between the strings and their #defines. Those will be accounted for in a following commit. Signed-off-by: Gary Oberbrunner <[email protected]>
See `get_cname` and `find_stringname` in gen-props.py, and the new `cname` member of the props metadata. Signed-off-by: Gary Oberbrunner <[email protected]>
Replaced a vector with a std::array for reduced memory & startup time. Also add static_assert checks for all action names vs. their #defines. Signed-off-by: Gary Oberbrunner <[email protected]>

Also separate out Actions from prop sets in ofx-props.yml, for cleanliness. Signed-off-by: Gary Oberbrunner <[email protected]>

include/ofx-props.ymlis the property reference/metadatascripts/gen-props.pyis the checker and source generatorAll props are included in the YML definition, and the script generates C++ files with all the property metadata and suite assignments. The C++ files aren't yet checked in, but you can build them easily:
python scripts/gen-props.py -vand then look ininclude/gen_*.hxx.
