This saves a *tiny* bit of typing, but at the cost of requiring either
the current solution of throwing up our hands and saying "typing is too
hard, better to have bugs!" or an extensive amount of `TypedDict`s,
`overloads`, and a very new version of mypy. Let's get our type safety
back, even if it means writing a little bit more code.
By adding the option name to UserOption object, it is now possible to
display the name of the affected option when the given option value is
not valid.
Fixes#12635
This solves rebuild issues when e.g. importing a .pxd header from a .pyx
file, just like C/C++ source headers. The transpiler needs to run again
in this case.
This functionality is present in the 3.0.0 alphas of cython, and is also
backported to 0.29.33.
Fixes#9049
It is always used as an immutable view so there is no point in doing
copies. However, mypy insist it must implement the same APIs as
Dict[OptionKey, UserOption[Any]] so keep faking it.
This patch adds a new meson built-in option for cython, allowing it to
target C++ instead of C as the intermediate language. This can, of
course, be done on a per-target basis using the `override_options`
keyword argument, or for the entire project in the project function.
There are some things in this patch that are less than ideal. One of
them is that we have to add compilers in the build layer, but there
isn't a better place to do it because of per target override_options.
There's also some design differences between Meson and setuptools, in
that Meson only allows options on a per-target rather than a per-file
granularity.
Fixes#9015
