* Emit struct literal with list-initializer when language is Cxx
* Update test results
* Add test case - struct literal order
* Memoize struct field names
* Specify struct type at front of initializer
This required two changes in parallel.
As a first and obvious step it removes a check that skipped emptys
lines during documentation loading, but it was also necessary to
refactore the `get_comment_lines()` utility method as a second step.
This second refactoring was necessary as each line in a doc comment
is trimmed and transformed in its own doc attribute. The attribute
of an empty line therefore contains an empty string as value. If we
now call `lines()` on such an empty string we end up with an empty
iterator as the method is internally configured to ignore trailing
empty lines.
Using operator= is not quite sound in presence of destructors and operator
overloading.
It's perfectly fine to assume that the left-hand-side of an operator= expression
is valid memory, however we're using uninitialized memory here, that may not be
the case.
Use placement new to properly construct tagged unions. I don't need this with
any urgency, but it's the right thing to do in presence of complex types, and
the current code seems a bomb waiting to explode :)
The static_cast is needed to avoid -Wnarrowing conversions, but I can also write
it like:
Foo ret;
ret.bits = bits | other.bits;
return ret;
if you prefer.
Opt-in since it uses a C++17 feature, but this allow exactly the same usage in
C++ and Rust, which I think is nice.
This also fixes constants of transparent structs in general, since the initial
version of this patch broke a test (associated constants in enums), so I added a
test for that too.
