Print namespace-scope typedefs of builtins by their typedef name#28
Merged
Conversation
gfqn_impl1 checked getAs<BuiltinType>() before getAs<TypedefType>(). Since getAs<> looks through sugar, a typedef of a builtin such as std::uint64_t matched the builtin branch first and was printed with its canonical spelling, which is platform dependent (unsigned long long on macOS vs unsigned long on Linux LP64). Inside composite types this changes the type, e.g. std::vector<unsigned long long> does not convert to std::vector<std::uint64_t> on Linux, so committed wrap files generated on macOS failed to compile there. Prefer the typedef spelling only for typedefs declared at namespace or translation-unit scope: member typedefs (e.g. of a class template) keep the canonical builtin print, as their qualified name can lose the template arguments (detail::linear::index_t).

c2py declares the same option with default OFF at its top level, which lands in the cache before doc/ is configured. The getting_started example's own option(... ON) then becomes a no-op, the *_bindings_generation target is never created, and the docs CI fails compiling getting_started.cpp with 'getting_started.wrap.cxx file not found'. Set the value as a normal variable in doc/CMakeLists.txt so it overrides the cache for the docs scope only. Assisted-by: Claude <[email protected]>

Avoid replacing typedef aliases to built-in types, such as
size_torstd::uint64_t.
