By moving to use our `uniform_integer_distribution`, which is
reproducible across different platforms, instead of the stdlib
one which is not, we can provide reproducible results for `float`s
and `double`s. Still no reproducibility for `long double`s, because
those are too different across different platforms.
* Utility for extended mult n x n bits -> 2n bits
* Utility to adapt output from URBG to target (unsigned) integral
type
* Utility to reorder signed values into unsigned type while keeping
the order.
Specifically we add
* `gamma(a, b)`, which returns the magnitude of largest 1-ULP
step in range [a, b].
* `count_equidistant_float(a, b, distance)`, which returns the
number of equi-distant floats in range [a, b].
The base images for GitHub Actions are updated weekly, but
sometimes that is not enough to be able to install the packages
we require. The recommended fix for this is to always run
`apt-get update` before `apt-get install`.
We do not support specific compilers, but rather compilers with
reasonable quality of their C++14 support. While developing the
new random generators, I ran into issues with VS2017 where it
rejects perfectly valid C++14 code, **and** the error does not
point me in the right direction to try and work around the issue.
It is time for VS2017 to go.
Together with liberal use of `_sr` UDL to compile-time convert
string literals into StringRefs, this will reduce the number of
allocation and remove most of the strcpy calls inherent in
converting string lits into `std::string`s.
Did this, because with 3.0.1, the files
- catch_xmlwriter.cpp
- catch_string_manip.hpp
- catch_test_case_info.hpp
were missing
This led to some obvious and some obscure compile errors when compiling
with g++ 13.2.0 (std c++17 or c++20)
One of these errors being "Elaborated-type-specifier for a scoped enum
must not use the ‘class’ keyword"
Since this is a rather bad experience and debugging it is
time-consuming, I suggest to simply boost the recommended version in the
snippet which is likely copied by new Catch2 users
Because the issue comes from the expansions of `UNSCOPED_INFO`,
surrogate TUs could not catch this bug, and in common usage, the
include transitively comes from `catch_test_macros.hpp`.
Fixes#2758
These options are rather low-level and don't need to be seen in the
CMake cache unless you opt into seeing all other advanced options.
This removes a lot of cache entries from the screen when using a GUI
or TUI to view the cache thus making it easier for users to focus on
the cache variables they're more likely to change on a frequent
basis.
Technically, the declaration should not have a space between
the quotes and the underscore, because `_foo` is a reserved
identifier, but `""_foo` is not. In general it works, but newer
Clang versions warn about this, because WG21 wants to deprecate
and later remove this form completely.
The existing formatting created one-element lists separated by paragraphs, when it would make more sense to have the paragraphs that are providing more information about one of those list entries be part of the list entry itself.
I think this makes the documentation easier to read in both markdown and html form, and should also improve the structure for assistive technologies.
