A C library, tools/dat-cli/native, that reads the archives into the game's own types on any platform, from tables `melee-dat native codegen` writes from the DWARF. It's a port of the walk that converts as it goes, so `melee-dat native expect` and the library's trace must agree: they do for all 7048 archives on 64-bit and 32-bit little-endian and 32-bit big-endian (under qemu), and every converted object reads back against its data. The dat preset builds it with the host's compiler and runs its tests in ctest. - the walk lays queued objects out as they were reached, so typedef tags apply (the CPU attack lists' DAT_TERMINATED was ignored) - CPU attack tables typed (ftCo_AttackList); stage param types moved into their headers; stage param fields typed as their data - 47 dat_symbols.txt aliases that read stage data as material animations removed - generated C casts only between different types; untyped data typed from the fields that point to it - `samples report --incomplete`, why units aren't complete - a `native` dev shell with the DWARF/dat tools, qemu and a ppc32 cross compiler; the default shell is what CI needs - clang-tidy's checks stay on src/: tools/ and the generated tables opt out Co-Authored-By: Claude Opus 5.5 <[email protected]> * dat: native schema as descriptors per type, a file per header, enum type indices `melee-dat native codegen` writes a directory instead of one tables.c: each type is a named `dat_type_*` descriptor with its members, in types/<header>.c for the header that declares it, along with what refers to it (pointers, arrays); roots are in roots/<module>.c; DAT_TYPE_* and DAT_NAME_* are enums. Descriptors use designated initializers, refer to types by name and keep expressions next to their members, with the annotation as written in a comment where it isn't plain. - dat/schema.h: the schema's types and the macros descriptors are written in; DAT_NONE is 0, so every field defaults to zero - members, expressions, scripts, binds and roots are pointers, not ranges of shared tables; macros expand to a depth when evaluated - the schema is generated when configuring, again when its inputs change - codegen split into generator.rs (the rows) and emit.rs (the C) Co-Authored-By: Claude Opus 5.5 <[email protected]>
