As part of `-Wdeprecated-copy-dtor` sweep, I noticed that Capturer's
copies are defaulted. Given that the class would likely break horribly
in the event of actual copy happening, they are now deleted.
This should improve the compilation times by decreasing the number
of TUs compiled, without making overly big TUs that would cause
problems with heavy-tailed compilation times.
There is one "combined TU" for the top level part, and each subpart,
except for Reporters, which currently do not have any trivial TUs.
Special member functions are now implicit, which should make them
both noexcept and constexpr. The `operator<<` has been made into
hidden friend as per best practices.
As Clara is no longer maintained as a separate project, the
implementation was moved to the internal subfolder of top-level
folder. This removes one folder and avoids potential user confusion.
Also simplified the convenience header checking script accordingly.
There are two reasons for this:
1) It is highly unlikely that someone has use for this header,
which has no customization points and only provides simplest
possible main, and cannot link the static library which also
provides a default main implementation.
2) It being a header was causing extra complications with
the convenience headers, and our checking script. This would either
require special handling in the checking script, or would break user's
of the main convenience header.
All in all, it is simpler and better in the long term to remove it,
than to fix its problems.
I do not think we need a safeguard against not including files in
CMake anymore, and as it is, it caused annoying false positive about
the default main implementation.
At some point we moved over to catch2:catchorg (notice lowercase `c`)
instead of Catch2:catchorg, but we kept uploading the released
packages to the upper-cased repository... Time to fix this, and then
merge them again.
The naming scheme is simple, to include all matchers, include header
`catch2/matchers/catch_matchers_all.hpp`. To include **everything**,
include `catch2/catch_all.hpp`.
This describes the reality better, as it also links in the rest
of Catch2.
The on-disk name of the static library remains just `Catch2Main`,
as that is what it is -- single main function -- and on-disk artifacts
cannot describe link dependencies.
It is no longer used by v3, and contains obsolete versions of the
headers anyway. There are future plans for some sort of replacement,
but those are,
1) in the future
2) different than the single header model
so we can delete the folder completely.
Originally the tests were from #1912, but as it turned out, the issue
was somewhere else. Still, the inputs provided were interesting, so
they are now part of our test suite.
