RFC: Source generators about ffxivclientstructs HOT 8 CLOSED

Some sort of initialize function would also need to exist, so as to feed in the Scanner.Module.BaseAddress ptr, so the updated offsets can be calculated.

ffs. how many times am i going to login and do stuff with my work account. you'd think i'd have noticed.

Can delete it and repost if you want.

Anyway.

vtbl addresses dont need to be in the code. You just read them from the current object. This allows polymorphism to actually work.

Function signatures I haven't really thought about. One option is to store them in a header file as actual C++ function signatures then use something like CppSharp's parser to read them during codegen.

It should be possible to use a static initializer to store the game's base address when the dll loads, unless I'm mistaken.

C#9 has [ModuleInitializer]
Prior to that, Fody has ModuleInit
Or the option of a static constructor on something potentially.

Been thinking, generating and stuffing offsets in code is handy dandy, but requires rebuilding every patch. What if it gets generated, but packs data.yml with the dll. If out of date (since ffxiv.ver is in the file now) reach out to github, pull down a new data, if good, update the offsets. Won't be able to generate anything that's new or not, but at the very least it'll have good offsets.

Pretty sure it forces the TFM to netstandard2.0, which should? leave us compatible with net472. Haven't tried loading it into XL though. I can't find it again, but I swear some Msft doc said netstandard2.0 was on par with net45.

re: Linking original structs to generated data.

• 1: some stupid getter function on a static class. boo
• 2: extension class adding a getter to each struct. maybe
• 3: weave them into each class with something (fody?). My favorite idea, requires adding another thing onto the dependency stack though. Source generators are purely additive, afaik it wouldn't be possible to add to an existing object this way.
