This PR introduces a new `TEST_CASE` macro called `TEST_CASE_PERSISTENT_FIXTURE`. `TEST_CASE_PERSISTENT_FIXTURE` offers the same functionality as `TEST_CASE_METHOD` except for one difference. The object on which the test method is invoked is only created once for all invocations of the test case. The object is created just after the `testCaseStarting` event is broadcast and the object is destroyed just before the `testCaseEnding` event is broadcast.
The main motivation for this new functionality is to allow `TEST_CASE`s to do expensive setup and teardown once per `TEST_CASE`, without having to resort to abusing event listeners or static function variables with manual initialization.
Implements #1602

Technically we should be able to remove moveability as well, but
then we would need a larger surgery. This already improves the
compile times and binary sizes by a surprising amount.
Since the last time, macos-12 has fixed the toolchain's linker
crash bug, so we can update here. macos-13 has a new and exciting
bug when unwinding exceptions in binaries compiled with GCC, so
we cannot update all the way at this time.
This PR adds functionality to skip around ANSI escape sequences in catch_textflow so they do not contribute to line length and line wrapping code does not split escape sequences in the middle. I've implemented this by creating a AnsiSkippingString abstraction that has a bidirectional iterator that can skip around escape sequences while iterating. Additionally I refactored Column::const_iterator to be iterator-based rather than index-based so this abstraction is a simple drop-in for std::string.
Currently only color sequences are handled, other escape sequences are left unaffected.
Motivation: Text with ANSI color sequences gets messed up when being output by Catch2 #2833.
`max_digits10` is the number of decimal digits that the type _can_
represent, in other words, the number of decimal digits needed to
disambiguate any two floating point numbers when serialized to
a string.
Closes#1210
When a signal is caught, the destructors of Sections will not be called.
Thus, we must call `sectionEndedEarly` manually for those Sections.
Example test case:
```
TEST_CASE("broken") {
SECTION("section") {
/// Use illegal cpu instruction
__asm__ __volatile__("ud2" : : : "memory");
}
}
```
This PR primarily accomplishes two tasks:
1) It adds MODULE.bazel.lock to the .gitignore file.
2) It includes a Bazel build rule for SelfTest, which can be utilized with the command bazel test //tests:catch2_self_test.
The "Catch2 without default main" target is currently unspecified in
Conan, and defaults to catch2::catch2base. This commit switches it back
to Catch2::Catch2, as specified in the docs.
Remove `#pragma intrinsic(_umul128)` because it doesn't work on
ARM64EC and x64 works without it.

The Catch libraries have different API/ABI depending on the c++
standard they are compiled with. For example, the following function
isn't in the binary when compiled with C++14, only with C++17 or later:
StringMaker<std::string_view>::convert(std::string_view str);
By default, Conan is allowed to serve Catch libraries compiled in C++14
into a project using C++17/20, potentially causing linker errors
because of missing symbols. This PR overrides this default behaviour:
the C++ standard of the Catch library will exactly match the one of
the requiring project (building Catch from source if necessary).
The WithinRelMatcher does not listen to the precision specification; it just naively pipes to stringstream. If you specify the precision, that has no impact on the outputted values when the match fails.
This fix makes the WithinRelMatcher listen to the precision (https://github.com/catchorg/Catch2/blob/devel/docs/tostring.md#floating-point-precision) specified by: Catch::StringMaker<float>::precision
The issue was that `capture_by_value` was meant to be specialized
by plain type, e.g. `capture_by_value<std::weak_ordering>`, but
the TMP in Decomposer did not properly throw away `const` (and
`volatile`) qualifiers, before taking the value of `capture_by_value`.
Our implementation should be slightly faster, and has the
advantage of being consistent between platforms. This does not
have immediate user impact, because we currently use random_device
to generate random seed for resampling, but if we decide to change
this in the future, it is one less place to fix.
Now we use intrinsics when possible, and fallback to optimized
implementation in portable C++. The difference is about 4x when
we can use intrinsics and about 2x when we cannot.
This should speed up our Lemire's algorithm implementation nicely.
The previously used `make_unsigned` approach combined with the overload
set of `extendedMult` caused compilation issues on MacOS platform. By
forcing the selection to be one of `std::uintX_t` types we don't need
to complicate the overload set further.
Previously it could be just plain reporter name, e.g. `xml`, but
it could not specify other reporter options. This change is not
particularly useful for the built-in reporters, as it mostly comes
in handy for combining specific custom reporter with custom arguments,
and the built-in reporters do not have those.
Previously these were removed in bbba3d8a06,
to allow Decomposer changes that were not compatible with old
GCCs. However, the compatibility was restored in
459ac8562b, and so we can restore
the builds again.
This target previously did not specify its minimum C++ standard.
AppleClang was emitting warnings about the use of C++11 features
which is fixed by telling CMake that this target requires C++14.
Because this target does not link to the existing CMake targets
it never inherited that C++ standard requirement.
* Improve Conan recipe support
* export files
* supports c++14
* update Conan client in the CI
* Better compatibility with Conan 1.x
* Manage options and cppstd for Conan 1.x
* copy eveything from extra
