Hello Paul,
I would like to discuss formatting rules to make sure there is no ambiguity for future contributions. I use to clang-format everything and call it a day as it is clean, consistent, and easy to follow. I just wanted to know how you approach that matter to make sure I don't step on your boundaries.
Regards,
Jules
Currently make test
only works from within the tests
subdirectory.
Hello Paul,
GCC 12.1 released with some very welcome updates, including the following
std::vector
,std::basic_string
,std::optional
, andstd::variant
can be used in constexpr functions.
Full change list: https://gcc.gnu.org/gcc-12/changes.html
It might be worth replacing Cest's implementation of these containers with alias types (and maybe add those that aren't available in Cest ?). So far, replacing cest::vector
with std::vector
in my Brainfuck meta-compiler didn't break anything.
constexpr std::unique_ptr
was also implemented as an experimental C++23, although I didn't test it yet:
std::unique_ptr can be used in constexpr functions.
So cest::unique_ptr
might be subject for this change too at some point (if not already).
As a side note, this change isn't directly related to Cest but might be worth checking out:
New command-line option
-fimplicit-constexpr
can be used to make inline functions implicitly constexpr
Regards,
Jules
Not urgent, but this will be needed in the future to ensure tests don't take too long to compile and run
