Removed the `generic` nested namespace, so PredicateMatcher now
lives in `Catch::Matchers` namespace, just like other matchers.
Also cleaned up and doxygenized comments on the `Predicate` factory
function for `PredicateMatcher`.
The two changes are
`catch_matchers_templates` -> `catch_matchers_templated` and
`catch_matchers_generic` -> `catch_matchers_predicate`. The former
is mostly cosmetic, but the second was previously significantly
misleading, and as the library is now to be consumed by including
specific headers, this needed to be fixed.
`SizeIs` can accept both `size_t` and a matcher. In the first case,
it checks whether the size of the range is equal to specified size.
In the second case, it checks whether the provided matcher accepts
the size of the range.
Outside of `MatcherBase` and `GenericMatcherBase`, matchers are not
designed to be overriden. This means that doing so can easily lead
to errors, and matchers are generally fairly simple functionality-wise.
so there is not much code reuse to be gained anyway.
Thus, Catch2-provided concrete matchers are now final.
In general, for Catch2 v3 we are making virtual types `final`,
unless they were explicitly designed to be derived-from.
`ListeningReporter` is definitely not designed to be derived-from.
This was previously used to avoid `dynamic_cast` inside our code,
when we were creating more than one reporter, or a reporter
together with listeners. However, since then the offending code
was refactored to be smarter instead, and this query member function
is no longer needed nor used.
The only way to stream those is to use the `bool` overload of `op<<`.
However, to convert a function to bool, GCC creates AST equivalent
of `A? true : false`. Then, because `A` is a function, it warns that
it will never be `false`. 🤦
As a bonus, newer GCC versions issue _two_ different warnings about
this, but older GCC versions do not know both of them, so we also
have to suppress warning about unknown warning suppression.
The variable initialization has test registration as a side-effect,
but as far as GCC is concerned, the variable itself is unused.
Because the macro substitution always happens at global scope, we
cannot use cast to `void` as is usually done.
Sadly most versions still cannot properly handle the suppression
via `_Pragma`, so it has to leak to the users when they use older
GCC versions to compile their code
In the future we can expect many more matchers, so let's give them
a place to live.
Also moved matcher-related internal files to `internal` subfolder.
Ideally we should sort out all of our source code, but that will
have to come later.
This commit also forbids composing lvalues of composed matchers, as
per previous deprecation notice. I do not expect this to be contentious
in practice, because there was a bug in that usage for years, and
nobody complained.
Given that in the 2 or so years that matchers are thing nobody complained,
it seems that people do not actually write this sort of code, and the
possibility will be removed in v3. However, to avoid correctness bugs,
we will have to support this weird code in v2.
C++11 math requires _GLIBCXX_USE_C99_MATH_TR1 to be true with gcc/clang.
Also fixes an issue with uClibc-ng where __UCLIBC__ is defined in features.h but
that is not included here and is thus no-op.
- Overrides added
- usages of push_back() replaced with emplace_back()
- Loop variable made const-refernce
- NULL replaced with nullptr
- Names used in the declaration and definition unified
- size() replaced with empty
- Identical cases merged
This commit extends the Matchers feature with the ability to have type-independent (e.g. templated) matchers. This is done by adding a new base type that Matchers can extend, `MatcherGenericBase`, and overloads of operators `!`, `&&` and `||` that handle matchers extending `MatcherGenericBase` in a special manner.
These new matchers can also take their arguments as values and non-const references.

b77cec05c0 fixed this problem for tagging tests, so that a test
case tagged with `[.foo]` would be parsed as tagged with `[.][foo]`.
This does the same for the test spec parsing.
Fixes#1798
Copying a `ReusableStringStream` would lead to "double free" of
the stream, and thus it could be used in multiple places at the
same time, breaking the output.
On systems where std::chrono::steady_clock::period is not std::nano, benchmark tests fail to compile due to trying to convert analysis.samples from a vector of duration<double, clock::period> to a vector of std::chrono::duration<double, std::nano>.
Its intent was to show which headers are expected to be useable by
Catch2's users, and to enforce their inclusion in the single header
distribution at the right place.
Given the new library model, the second use case is not needed and
the first one is better served with documentation and physical file
layout.
Now that Catch2 is a proper library, we can always build the full
library (comparatively minor slowdown) and the user can avoid
including benchmarking headers to avoid the compilation slowdown.
The use we previously used the polyfill or naked new is that we
supported C++11, which did not yet have `std::make_unique`. However,
with the move to C++14 as the minimum, `std::make_unique` can be
expected to be always available.
Because some of the tooling used by Catch2 does not properly support
version postfixes, such as `preview-1`, we will report the
in-development version is `v3.0.0`, and the first real release will
have to be `v3.0.1`.
Closes#1824
Now that the recommended distribution and usage method is proper
library, users can just avoid including the matcher headers to get
basically the same effect.
