   * include "catch.hpp" again
 
 
-### CMake
-
-In general we recommend "vendoring" Catch's single-include releases inside your own repository. If you do this, the following example shows a minimal CMake project:
-```CMake
-cmake_minimum_required(VERSION 3.0)
-
-project(cmake_test)
-
-# Prepare "Catch" library for other executables
-set(CATCH_INCLUDE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/catch)
-add_library(Catch INTERFACE)
-target_include_directories(Catch INTERFACE ${CATCH_INCLUDE_DIR})
-
-# Make test executable
-set(TEST_SOURCES ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp)
-add_executable(tests ${TEST_SOURCES})
-target_link_libraries(tests Catch)
-```
-Note that it assumes that the path to the Catch's header is `catch/catch.hpp` from the `CMakeLists.txt` file.
-
-
-You can also use the following CMake snippet to automatically fetch the entire Catch repository from github and configure it as an external project:
-```CMake
-cmake_minimum_required(VERSION 2.8.8)
-project(catch_builder CXX)
-include(ExternalProject)
-find_package(Git REQUIRED)
-
-ExternalProject_Add(
-    catch
-    PREFIX ${CMAKE_BINARY_DIR}/catch
-    GIT_REPOSITORY https://github.com/philsquared/Catch.git
-    TIMEOUT 10
-    UPDATE_COMMAND ${GIT_EXECUTABLE} pull
-    CONFIGURE_COMMAND ""
-    BUILD_COMMAND ""
-    INSTALL_COMMAND ""
-    LOG_DOWNLOAD ON
-   )
-
-# Expose required variable (CATCH_INCLUDE_DIR) to parent scope
-ExternalProject_Get_Property(catch source_dir)
-set(CATCH_INCLUDE_DIR ${source_dir}/single_include CACHE INTERNAL "Path to include folder for Catch")
-```
-
-If you put it in, e.g., `${PROJECT_SRC_DIR}/${EXT_PROJECTS_DIR}/catch/`, you can use it in your project by adding the following to your root CMake file:
-
-```CMake
-# Includes Catch in the project:
-add_subdirectory(${EXT_PROJECTS_DIR}/catch)
-include_directories(${CATCH_INCLUDE_DIR} ${COMMON_INCLUDES})
-enable_testing(true)  # Enables unit-testing.
-```
-
-The advantage of this approach is that you can always automatically update Catch to the latest release. The disadvantage is that it means bringing in lot more than you need.
-
-
-### Automatic test registration
-We provide 2 CMake scripts that can automatically register Catch-based
-tests with CTest,
-  * `contrib/ParseAndAddCatchTests.cmake`
-  * `contrib/CatchAddTests.cmake`
-
-The first is based on parsing the test implementation files, and attempts
-to register all `TEST_CASE`s using their tags as labels. This means that
-these:
-
-```cpp
-TEST_CASE("Test1", "[unit]") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-
-TEST_CASE("Test2") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-
-TEST_CASE("Test3", "[a][b][c]") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-```
-would be registered as 3 tests, `Test1`, `Test2` and `Test3`,
-and 4 CTest labels would be created, `a`, `b`, `c` and `unit`.
-
-
-The second is based on parsing the output of a Catch binary given
-`--list-test-names-only`. This means that it deals with inactive
-(e.g. commented-out) tests better, but requires CMake 3.10 for full
-functionality.
-
 ### CodeCoverage module (GCOV, LCOV...)
 
 If you are using GCOV tool to get testing coverage of your code, and are not sure how to integrate it with CMake and Catch, there should be an external example over at https://github.com/fkromer/catch_cmake_coverage
 
+
+### pkg-config
+
+Catch2 provides a rudimentary pkg-config integration, by registering itself
+under the name `catch2`. This means that after Catch2 is installed, you
+can use `pkg-config` to get its include path: `pkg-config --cflags catch2`.
+
+### gdb and lldb scripts
+
+Catch2's `contrib` folder also contains two simple debugger scripts,
+`gdbinit` for `gdb` and `lldbinit` for `lldb`. If loaded into their
+respective debugger, these will tell it to step over Catch2's internals
+when stepping through code.

+[Installing Catch2 from git repository](#installing-catch2-from-git-repository)<br>
+
+Because we use CMake to build Catch2, we also provide a couple of
+integration points for our users.
+
+1) Catch2 exports a (namespaced) CMake target
+2) Catch2's repository contains CMake scripts for automatic registration
+of `TEST_CASE`s in CTest
+
+## CMake target
+
+Catch2's CMake build exports an interface target `Catch2::Catch2`. Linking
+against it will add the proper include path and all necessary capabilities
+to the resulting binary.
+
+This means that if Catch2 has been installed on the system, it should be
+enough to do:
+```cmake
+find_package(Catch2 REQUIRED)
+target_link_libraries(tests Catch2::Catch2)
+```
+
+
+This target is also provided when Catch2 is used as a subdirectory.
+Assuming that Catch2 has been cloned to `lib/Catch2`:
+```cmake
+add_subdirectory(lib/Catch2)
+target_link_libraries(tests Catch2::Catch2)
+```
+
+## Automatic test registration
+
+Catch2's repository also contains two CMake scripts that help users
+with automatically registering their `TEST_CASE`s with CTest. They
+can be found in the `contrib` folder, and are
+
+1) `Catch.cmake` (and its dependency `CatchAddTests.cmake`)
+2) `ParseAndAddCatchTests.cmake`
+
+If Catch2 has been installed in system, both of these can be used after
+doing `find_package(Catch2 REQUIRED)`. Otherwise you need to add them
+to your CMake module path.
+
+### `Catch.cmake` and `AddCatchTests.cmake`
+
+`Catch.cmake` provides function `catch_discover_tests` to get tests from
+a target. This function works by running the resulting executable with
+`--list-test-names-only` flag, and then parsing the output to find all
+existing tests.
+
+#### Usage
+```cmake
+cmake_minimum_required(VERSION 3.5)
+
+project(baz LANGUAGES CXX VERSION 0.0.1)
+
+find_package(Catch2 REQUIRED)
+add_executable(foo test.cpp)
+target_link_libraries(foo Catch2::Catch2)
+
+include(CTest)
+include(Catch)
+catch_discover_tests(foo)
+```
+
+
+#### Customization
+`catch_discover_tests` can be given several extra argumets:
+```cmake
+catch_discover_tests(target
+                     [TEST_SPEC arg1...]
+                     [EXTRA_ARGS arg1...]
+                     [WORKING_DIRECTORY dir]
+                     [TEST_PREFIX prefix]
+                     [TEST_SUFFIX suffix]
+                     [PROPERTIES name1 value1...]
+                     [TEST_LIST var]
+)
+```
+
+* `TEST_SPEC arg1...`
+
+Specifies test cases, wildcarded test cases, tags and tag expressions to
+pass to the Catch executable alongside the `--list-test-names-only` flag.
+
+
+* `EXTRA_ARGS arg1...`
+
+Any extra arguments to pass on the command line to each test case.
+
+
+* `WORKING_DIRECTORY dir`
+
+Specifies the directory in which to run the discovered test cases.  If this
+option is not provided, the current binary directory is used.
+
+
+* `TEST_PREFIX prefix`
+
+Specifies a _prefix_ to be added to the name of each discovered test case.
+This can be useful when the same test executable is being used in multiple
+calls to `catch_discover_tests()`, with different `TEST_SPEC` or `EXTRA_ARGS`.
+
+
+* `TEST_SUFFIX suffix`
+
+Same as `TEST_PREFIX`, except it specific the _suffix_ for the test names.
+Both `TEST_PREFIX` and `TEST_SUFFIX` can be specified at the same time.
+
+
+* `PROPERTIES name1 value1...`
+
+Specifies additional properties to be set on all tests discovered by this
+invocation of `catch_discover_tests`.
+
+
+* `TEST_LIST var`
+
+Make the list of tests available in the variable `var`, rather than the
+default `<target>_TESTS`.  This can be useful when the same test
+executable is being used in multiple calls to `catch_discover_tests()`.
+Note that this variable is only available in CTest.
+
+
+### `ParseAndAddCatchTests.cmake`
+
+`ParseAndAddCatchTests` works by parsing all implementation files
+associated with the provided target, and registering them via CTest's
+`add_test`. This approach has some limitations, such as the fact that
+commented-out tests will be registered anyway.
+
+
+#### Usage
+
+```cmake
+cmake_minimum_required(VERSION 3.5)
+
+project(baz LANGUAGES CXX VERSION 0.0.1)
+
+find_package(Catch2 REQUIRED)
+add_executable(foo test.cpp)
+target_link_libraries(foo Catch2::Catch2)
+
+include(CTest)
+include(ParseAndAddCatchTests)
+ParseAndAddCatchTests(foo)
+```
+
+
+#### Customization
+
+`ParseAndAddCatchTests` provides some customization points:
+* `PARSE_CATCH_TESTS_VERBOSE` -- When `ON`, the script prints debug
+messages. Defaults to `OFF`.
+* `PARSE_CATCH_TESTS_NO_HIDDEN_TESTS` -- When `ON`, hidden tests (tests
+tagged with any of `[!hide]`, `[.]` or `[.foo]`) will not be registered.
+Defaults to `OFF`.
+* `PARSE_CATCH_TESTS_ADD_FIXTURE_IN_TEST_NAME` -- When `ON`, adds fixture
+class name to the test name in CTest. Defaults to `ON`.
+* `PARSE_CATCH_TESTS_ADD_TARGET_IN_TEST_NAME` -- When `ON`, adds target
+name to the test name in CTest. Defaults to `ON`.
+* `PARSE_CATCH_TESTS_ADD_TO_CONFIGURE_DEPENDS` -- When `ON`, adds test
+file to `CMAKE_CONFIGURE_DEPENDS`. This means that the CMake configuration
+step will be re-ran when the test files change, letting new tests be
+automatically discovered. Defaults to `OFF`.
+
+
+## CMake project options
+
+Catch2's CMake project also provides some options for other projects
+that consume it. These are
+
+* `CATCH_BUILD_TESTING` -- When `ON`, Catch2's SelfTest project will be
+built. Defaults to `ON`. Note that Catch2 also obeys `BUILD_TESTING` CMake
+variable, so _both_ of them need to be `ON` for the SelfTest to be built,
+and either of them can be set to `OFF` to disable building SelfTest.
+* `CATCH_BUILD_EXAMPLES` -- When `ON`, Catch2's usage examples will be
+built. Defaults to `OFF`.
+* `CATCH_INSTALL_DOCS` -- When `ON`, Catch2's documentation will be
+included in the installation. Defaults to `ON`.
+* `CATCH_INSTALL_HELPERS` -- When `ON`, Catch2's contrib folder will be
+included in the installation. Defaults to `ON`.
+* `BUILD_TESTING` -- When `ON` and the project is not used as a subproject,
+Catch2's test binary will be built. Defaults to `ON`.
+
+
+## Installing Catch2 from git repository
+
+If you cannot install Catch2 from a package manager (e.g. Ubuntu 16.04
+provides catch only in version 1.2.0) you might want to install it from
+the repository instead. Assuming you have enough rights, you can just
+install it to the default location, like so:
+```
+$ git clone https://github.com/catchorg/Catch2.git
+$ cd Catch2
+$ cmake -Bbuild -H. -DBUILD_TESTING=OFF
+$ sudo cmake --build build/ --target install
+```
+
+If you do not have superuser rights, you will also need to specify
+[CMAKE_INSTALL_PREFIX](https://cmake.org/cmake/help/latest/variable/CMAKE_INSTALL_PREFIX.html)
+when configuring the build, and then modify your calls to
+[find_package](https://cmake.org/cmake/help/latest/command/find_package.html)
+accordingly.

+when an assertion from the `REQUIRE` family of assertions fails. We also

+it can be forced to compile without exceptions by defining
+
+    CATCH_CONFIG_DISABLE_EXCEPTIONS
+
+Note that when using Catch2 without exceptions, there are 2 major
+limitations:
+
+1) If there is an error that would normally be signalled by an exception,
+the exception's message will instead be written to `Catch::cerr` and
+`std::terminate` will be called.
+2) If an assertion from the `REQUIRE` family of macros fails,
+`std::terminate` will be called after the active reporter returns.

+happens instead of exception being thrown. To use it, define
+
+    CATCH_CONFIG_DISABLE_EXCEPTIONS_CUSTOM_HANDLER
+

+# Data Generators
+
+_Generators are currently considered an experimental feature and their
+API can change between versions freely._
+
+Data generators (also known as _data driven/parametrized test cases_)
+let you reuse the same set of assertions across different input values.
+In Catch2, this means that they respect the ordering and nesting
+of the `TEST_CASE` and `SECTION` macros.
+
+How does combining generators and test cases work might be better
+explained by an example:
+
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE( range(1, 11) );
+
+    SECTION( "Some section" ) {
+        auto j = GENERATE( range( 11, 21 ) );
+        REQUIRE(i < j);
+    }
+}
+```
+
+the assertion will be checked 100 times, because there are 10 possible
+values for `i` (1, 2, ..., 10) and for each of them, there are 10 possible
+values for `j` (11, 12, ..., 20).
+
+You can also combine multiple generators by concatenation:
+```cpp
+static int square(int x) { return x * x; }
+TEST_CASE("Generators 2") {
+    auto i = GENERATE(0, 1, -1, range(-20, -10), range(10, 20));
+    CAPTURE(i);
+    REQUIRE(square(i) >= 0);
+}
+```
+
+This will call `square` with arguments `0`, `1`, `-1`, `-20`, ..., `-11`,
+`10`, ..., `19`.
+
+----------
+
+Because of the experimental nature of the current Generator implementation,
+we won't list all of the first-party generators in Catch2. Instead you
+should look at our current usage tests in
+[projects/SelfTest/UsageTests/Generators.tests.cpp](/projects/SelfTest/UsageTests/Generators.tests.cpp).

-Catch has some known limitations, that we are not planning to change.

 ### Process isolation in a test
 Catch does not support running tests in isolated (forked) processes.

+Catch also aims to provide a set of generic matchers. Currently this set

+
+Because of type inference limitations, the argument type of the predicate
+has to be provided explicitly. Example:
+```cpp

+             Predicate<std::string>(

+* Added a StringMaker for `std::variant` (#1380)
+  * This one is disabled by default to avoid increased compile-time drag
+* Added detection for cygwin environment without `std::to_string` (#1396, #1397)
+
+### Fixes
+* `UnorderedEqualsMatcher` will no longer accept erroneously accept
+vectors that share suffix, but are not permutation of the desired vector
+* Abort after (`-x N`) can no longer be overshot by nested `REQUIRES` and
+subsequently ignored (#1391, #1392)
+
+
+## 2.4.0
+
+**This release brings two new experimental features, generator support
+and a `-fno-exceptions` support. Being experimental means that they
+will not be subject to the usual stability guarantees provided by semver.**
+
+### Improvements
+* Various small runtime performance improvements
+* `CAPTURE` macro is now variadic
+* Added `AND_GIVEN` macro (#1360)
+* Added experimental support for data generators
+  * See [their documentation](generators.md) for details
+* Added support for compiling and running Catch without exceptions
+  * Doing so limits the functionality somewhat
+  * Look [into the documentation](configuration.md#disablingexceptions) for details
+
+### Fixes
+* Suppressed `-Wnon-virtual-dtor` warnings in Matchers (#1357)
+* Suppressed `-Wunreachable-code` warnings in floating point matchers (#1350)
+
+### CMake
+* It is now possible to override which Python is used to run Catch's tests (#1365)
+* Catch now provides infrastructure for adding tests that check compile-time configuration
+* Catch no longer tries to install itself when used as a subproject (#1373)
+* Catch2ConfigVersion.cmake is now generated as arch-independent (#1368)
+  * This means that installing Catch from 32-bit machine and copying it to 64-bit one works
+  * This fixes conan installation of Catch
+
+
+## 2.3.0
+
+**This release changes the include paths provided by our CMake and
+pkg-config integration. The proper include path for the single-header
+when using one of the above is now `<catch2/catch.hpp>`. This change
+also necessitated changes to paths inside the repository, so that the
+single-header version is now at `single_include/catch2/catch.hpp`, rather
+than `single_include/catch.hpp`.**
+
+
+
+### Fixes
+* Fixed Objective-C++ build
+* `-Wunused-variable` suppression no longer leaks from Catch's header under Clang
+* Implementation of the experimental new output capture can now be disabled (#1335)
+  * This allows building Catch2 on platforms that do not provide things like `dup` or `tmpfile`.
+* The JUnit and XML reporters will no longer skip over successful tests when running without `-s`  (#1264, #1267, #1310)
+  * See improvements for more details
+
+### Improvements
+* pkg-config and CMake integration has been rewritten
+  * If you use them, the new include path is `#include <catch2/catch.hpp>`
+  * CMake installation now also installs scripts from `contrib/`
+  * For details see the [new documentation](cmake-integration.md#top)
+* Reporters now have a new customization point, `ReporterPreferences::shouldReportAllAssertions`
+  * When this is set to `false` and the tests are run without `-s`, passing assertions are not sent to the reporter.
+  * Defaults to `false`.
+* Added `DYNAMIC_SECTION`, a section variant that constructs its name using stream
+  * This means that you can do `DYNAMIC_SECTION("For X := " << x)`.
+
+
+## 2.2.3
+
+**To fix some of the bugs, some behavior had to change in potentially breaking manner.**
+**This means that even though this is a patch release, it might not be a drop-in replacement.**
+
+### Fixes
+* Listeners are now called before reporter
+  * This was always documented to be the case, now it actually works that way
+* Catch's commandline will no longer accept multiple reporters
+  * This was done because multiple reporters never worked properly and broke things in non-obvious ways
+  * **This has potential to be a breaking change**

+### Improvements
+* XML encoder now hex-encodes invalid UTF-8 sequences (#1207)
+  * This affects xml and junit reporters
+  * Some invalid UTF-8 parts are left as is, e.g. surrogate pairs. This is because certain extensions of UTF-8 allow them, such as WTF-8.

 Between tag expressions and wildcarded test names (as well as combinations of the two) quite complex patterns can be constructed to direct which test cases are run. If a complex pattern is used often it is convenient to be able to create an alias for the expression. This can be done, in code, using the following form:
 
-	CATCH_REGISTER_TAG_ALIAS( <alias string>, <tag expression> )
+    CATCH_REGISTER_TAG_ALIAS( <alias string>, <tag expression> )
 
 Aliases must begin with the `@` character. An example of a tag alias is:
 
-	CATCH_REGISTER_TAG_ALIAS( "[@nhf]", "[failing]~[.]" )
+    CATCH_REGISTER_TAG_ALIAS( "[@nhf]", "[failing]~[.]" )

 Most built-in or std types are supported out of the box but there are two ways that you can tell Catch how to convert your own types (or other, third-party types) into strings.

 ## Writing tests
 
 Let's start with a really simple example ([code](../examples/010-TestCase.cpp)). Say you have written a function to calculate factorials and now you want to test it (let's leave aside TDD for now).
