v2.13.2

The problem was that Catch2 did not reliably include `<exception>`

`<exception>` everywhere, the configuration check was split out
into a separate header.

Closes #2021

-So you want to contribute something to Catch? That's great! Whether it's a bug fix, a new feature, support for

-Of course so are bug reports and other comments and questions.

+a bug fix, a new feature, support for additional compilers - or just
+a fix to the documentation - all contributions are very welcome and very
+much appreciated. Of course so are bug reports, other comments, and
+questions, but generally it is a better idea to ask questions in our
+[Discord](https://discord.gg/4CWS9zD), than in the issue tracker.
 
-If you are contributing to the code base there are a few simple guidelines to keep in mind. This also includes notes to
-help you find your way around. As this is liable to drift out of date please raise an issue or, better still, a pull
-request for this file, if you notice that.
 
-## Branches
+This page covers some guidelines and helpful tips for contributing
+to the codebase itself.
 
-Ongoing development is currently on _master_. At some point an integration branch will be set-up and PRs should target
- that - but for now it's all against master. You may see feature branches come and go from time to time, too.
+## Using Git(Hub)
 
-## Directory structure
+Ongoing development happens in the `master` branch for Catch2 v2, and in
+`dev-v3` for the next major version, v3.
 
-_Users_ of Catch primarily use the single header version. _Maintainers_ should work with the full source (which is still,
-primarily, in headers). This can be found in the `include` folder. There are a set of test files, currently under
-`projects/SelfTest`. The test app can be built via CMake from the `CMakeLists.txt` file in the root, or you can generate
-project files for Visual Studio, XCode, and others (instructions in the `projects` folder). If you have access to CLion,
-it can work with the CMake file directly.
+Commits should be small and atomic. A commit is atomic when, after it is
+applied, the codebase, tests and all, still works as expected. Small
+commits are also prefered, as they make later operations with git history,
+whether it is bisecting, reverting, or something else, easier.
 
-As well as the runtime test files you'll also see a `SurrogateCpps` directory under `projects/SelfTest`.
-This contains a set of .cpp files that each `#include` a single header.
-While these files are not essential to compilation they help to keep the implementation headers self-contained.
-At time of writing this set is not complete but has reasonable coverage.
-If you add additional headers please try to remember to add a surrogate cpp for it.
+_When submitting a pull request please do not include changes to the
+single include. This means do not include them in your git commits!_
 
-The other directories are `tools/scripts` which contains a set of python scripts to help in testing Catch as well as
-generating the single include, and `docs`, which contains the documentation as a set of markdown files.
 
-__When submitting a pull request please do not include changes to the single include, or to the version number file
-as these are managed by the scripts!__
+When addressing review comments in a MR, please do not rebase/squash the
+commits immediately. Doing so makes it harder to review the new changes,
+slowing down the process of merging a MR. Instead, when addressing review
+comments, you should append new commits to the branch and only squash
+them into other commits when the MR is ready to be merged. We recommend
+creating new commits with `git commit --fixup` (or `--squash`) and then
+later squashing them with `git rebase --autosquash` to make things easier.
+
 
 
 ## Testing your changes
 
-Obviously all changes to Catch's code should be tested. If you added new
-functionality, you should add tests covering and showcasing it. Even if you have
-only made changes to Catch internals (i.e. you implemented some performance
-improvements), you should still test your changes.
+_Note: Running Catch2's tests requires Python3_
 
-This means 2 things
 
-* Compiling Catch's SelfTest project:
+Catch2 has multiple layers of tests that are then run as part of our CI.
+The most obvious one are the unit tests compiled into the `SelfTest`
+binary. These are then used in "Approval tests", which run (almost) all
+tests from `SelfTest` through a specific reporter and then compare the
+generated output with a known good output ("Baseline"). By default, new
+tests should be placed here.
+
+However, not all tests can be written as plain unit tests. For example,
+checking that Catch2 orders tests randomly when asked to, and that this
+random ordering is subset-invariant, is better done as an integration
+test using an external check script. Catch2 integration tests are written
+using CTest, either as a direct command invocation + pass/fail regex,
+or by delegating the check to a Python script.
+
+There are also two more kinds of tests, examples and "ExtraTests".
+Examples serve as a compilation test on the single-header distribution,
+and present a small and self-contained snippets of using Catch2 for
+writing tests. ExtraTests then are tests that either take a long time
+to run, or require separate compilation, e.g. because of testing compile
+time configuration options, and take a long time because of that.
+
+Both of these are compiled against the single-header distribution of
+Catch2, and thus might require you to regenerate it manually. This is
+done by calling the `generateSingleHeader.py` script in `scripts`.
+
+Examples and ExtraTests are not compiled by default. To compile them,
+add `-DCATCH_BUILD_EXAMPLES=ON` and `-DCATCH_BUILD_EXTRA_TESTS=ON` to
+the invocation of CMake configuration step.
+
+Bringing this all together, the steps below should configure, build,
+and run all tests in the `Debug` compilation.
+
+1. Regenerate the single header distribution
 ```
 $ cd Catch2
-$ cmake -Bdebug-build -H. -DCMAKE_BUILD_TYPE=Debug
+$ ./scripts/generateSingleHeader.py
+```
+2. Configure the full test build
+```
+$ cmake -Bdebug-build -H. -DCMAKE_BUILD_TYPE=Debug -DCATCH_BUILD_EXAMPLES=ON -DCATCH_BUILD_EXTRA_TESTS=ON
+```
+3. Run the actual build
+```
 $ cmake --build debug-build
 ```
-because code that does not compile is evidently incorrect. Obviously,
-you are not expected to have access to all the compilers and platforms
-supported by Catch2, but you should at least smoke test your changes
-on your platform. Our CI pipeline will check your PR against most of
-the supported platforms, but it takes an hour to finish -- compiling
-locally takes just a few minutes.
-
-
-* Running the tests via CTest:
+4. Run the tests using CTest
 ```
 $ cd debug-build
-$ ctest -j 2 --output-on-failure
+$ ctest -j 4 --output-on-failure -C Debug
 ```
-__Note:__ When running your tests with multi-configuration generators like
-Visual Studio, you might get errors "Test not available without configuration."
-You then have to pick one configuration (e.g. ` -C Debug`) in the `ctest` call.
-
-If you added new tests, approval tests are very likely to fail. If they
-do not, it means that your changes weren't run as part of them. This
-_might_ be intentional, but usually is not.
-
-The approval tests compare current output of the SelfTest binary in various
-configurations against known good outputs. The reason it fails is,
-_usually_, that you've added new tests but have not yet approved the changes
-they introduce. This is done with the `scripts/approve.py` script, but
-before you do so, you need to check that the introduced changes are indeed
-intentional.
 
 
-## Documenting your code
+## Writing documentation
 
 If you have added new feature to Catch2, it needs documentation, so that
 other people can use it as well. This section collects some technical
 information that you will need for updating Catch2's documentation, and
 possibly some generic advise as well.

-Now, for the generic tips:
-  * Usage examples are good
-  * Don't be afraid to introduce new pages
-  * Try to be reasonably consistent with the surrounding documentation
+Now, for some content tips:
+
+* Usage examples are good. However, having large code snippets inline
+can make the documentation less readable, and so the inline snippets
+should be kept reasonably short. To provide more complex compilable
+examples, consider adding new .cpp file to `examples/`.
+
+* Don't be afraid to introduce new pages. The current documentation
+tends towards long pages, but a lot of that is caused by legacy, and
+we know that some of the pages are overly big and unfocused.
+
+* When adding information to an existing page, please try to keep your
+formatting, style and changes consistent with the rest of the page.
+
+* Any documentation has multiple different audiences, that desire
+different information from the text. The 3 basic user-types to try and
+cover are:
+  * A beginner to Catch2, who requires closer guidance for the usage of Catch2.
+  * Advanced user of Catch2, who want to customize their usage.
+  * Experts, looking for full reference of Catch2's capabilities.

+and tips on things like code formatting, code constructions to avoid,
+and so on.

+### Formatting
+
+To make code formatting simpler for the contributors, Catch2 provides
+its own config for `clang-format`. However, because it is currently
+impossible to replicate existing Catch2's formatting in clang-format,
+using it to reformat a whole file would cause massive diffs. To keep
+the size of your diffs reasonable, you should only use clang-format
+on the newly changed code.

+## Deprecations
+
+### `--list-*` return values
+
+The return codes of the `--list-*` family of command line arguments
+will no longer be equal to the number of tests/tags/etc found, instead
+it will be 0 for success and non-zero for failure.
+
+
+### `--list-test-names-only`
+
+`--list-test-names-only` command line argument will be removed.
+
+
+### `ANON_TEST_CASE`
+
+`ANON_TEST_CASE` is scheduled for removal, as it can be fully replaced
+by a `TEST_CASE` with no arguments.
+
+
+### Secondary description amongst tags
+
+Currently, the tags part of `TEST_CASE` (and others) macro can also
+contain text that is not part of tags. This text is then separated into
+a "description" of the test case, but the description is then never used
+apart from writing it out for `--list-tests -v high`.
+
+Because it isn't actually used nor documented, and brings complications
+to Catch2's internals, description support will be removed.
+
+### SourceLineInfo::empty()
+
+There should be no reason to ever have an empty `SourceLineInfo`, so the
+method will be removed.
+
+
+### Composing lvalues of already composed matchers
+
+Because a significant bug in this use case has persisted for 2+ years
+without a bug report, and to simplify the implementation, code that
+composes lvalues of composed matchers will not compile. That is,
+this code will no longer work:
+
+```cpp
+            auto m1 = Contains("string");
+            auto m2 = Contains("random");
+            auto composed1 = m1 || m2;
+            auto m3 = Contains("different");
+            auto composed2 = composed1 || m3;
+            REQUIRE_THAT(foo(), !composed1);
+            REQUIRE_THAT(foo(), composed2);
+```
+
+Instead you will have to write this:
+
+```cpp
+            auto m1 = Contains("string");
+            auto m2 = Contains("random");
+            auto m3 = Contains("different");
+            REQUIRE_THAT(foo(), !(m1 || m2));
+            REQUIRE_THAT(foo(), m1 || m2 || m3);
+```
+
+
 ## Planned changes
 
+
+### Reporter verbosities
+
+The current implementation of verbosities, where the reporter is checked
+up-front whether it supports the requested verbosity, is fundamentally
+misguided and will be changed. The new implementation will no longer check
+whether the specified reporter supports the requested verbosity, instead
+it will be up to the reporters to deal with verbosities as they see fit
+(with an expectation that unsupported verbosities will be, at most,
+warnings, but not errors).
+
+
+### Output format of `--list-*` command line parameters
+
+The various list operations will be piped through reporters. This means
+that e.g. XML reporter will write the output as machine-parseable XML,
+while the Console reporter will keep the current, human-oriented output.

+TEST_CASE("B", "[.][bar]") {}

+specifying `[foo]` as the testspec will run test "A" and specifying

+`~[baz]` will run both tests. This behaviour is often surprising and will
+be changed so that hidden tests are included in a run only if they
+positively match a testspec.

 ### Console Colour API
 
 The API for Catch2's console colour will be changed to take an extra
 argument, the stream to which the colour code should be applied.
 
 
+### Type erasure in the `PredicateMatcher`
+
+Currently, the `PredicateMatcher` uses `std::function` for type erasure,
+so that type of the matcher is always `PredicateMatcher<T>`, regardless
+of the type of the predicate. Because of the high compilation overhead
+of `std::function`, and the fact that the type erasure is used only rarely,
+`PredicateMatcher` will no longer be type erased in the future. Instead,
+the predicate type will be made part of the PredicateMatcher's type.

 This is best explained with an example:
 ```cpp
 TEST_CASE("Generators") {

-    SECTION("one") {
-        auto j = GENERATE( -3, -2, -1 );
-        REQUIRE(j < i);
-    }
+    auto i = GENERATE(1, 3, 5);
+    REQUIRE(is_odd(i));
 }
 ```
 
-The assertion in this test case will be run 9 times, because there
-are 3 possible values for `i` (1, 2, and 3) and there are 3 possible
-values for `j` (-3, -2, and -1).
+The "Generators" `TEST_CASE` will be entered 3 times, and the value of
+`i` will be 1, 3, and 5 in turn. `GENERATE`s can also be used multiple
+times at the same scope, in which case the result will be a cartesian
+product of all elements in the generators. This means that in the snippet
+below, the test case will be run 6 (2\*3) times.
 
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE(1, 2);
+    auto j = GENERATE(3, 4, 5);
+}
+```
 
 There are 2 parts to generators in Catch2, the `GENERATE` macro together
 with the already provided generators, and the `IGenerator<T>` interface
 that allows users to implement their own generators.
 
+
+## Combining `GENERATE` and `SECTION`.
+
+`GENERATE` can be seen as an implicit `SECTION`, that goes from the place
+`GENERATE` is used, to the end of the scope. This can be used for various
+effects. The simplest usage is shown below, where the `SECTION` "one"
+runs 4 (2\*2) times, and `SECTION` "two" is run 6 times (2\*3).
+
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE(1, 2);
+    SECTION("one") {
+        auto j = GENERATE(-3, -2);
+        REQUIRE(j < i);
+    }
+    SECTION("two") {
+        auto k = GENERATE(4, 5, 6);
+        REQUIRE(i != k);
+    }
+}
+```
+
+The specific order of the `SECTION`s will be "one", "one", "two", "two",
+"two", "one"...
+
+
+The fact that `GENERATE` introduces a virtual `SECTION` can also be used
+to make a generator replay only some `SECTION`s, without having to
+explicitly add a `SECTION`. As an example, the code below reports 3
+assertions, because the "first" section is run once, but the "second"
+section is run twice.
+
+```cpp
+TEST_CASE("GENERATE between SECTIONs") {
+    SECTION("first") { REQUIRE(true); }
+    auto _ = GENERATE(1, 2);
+    SECTION("second") { REQUIRE(true); }
+}
+```
+
+This can lead to surprisingly complex test flows. As an example, the test
+below will report 14 assertions:
+
+```cpp
+TEST_CASE("Complex mix of sections and generates") {
+    auto i = GENERATE(1, 2);
+    SECTION("A") {
+        SUCCEED("A");
+    }
+    auto j = GENERATE(3, 4);
+    SECTION("B") {
+        SUCCEED("B");
+    }
+    auto k = GENERATE(5, 6);
+    SUCCEED();
+}
+```

 Because Catch is implemented *entirely* in headers you might think that the whole of Catch must be compiled into every translation unit that uses it! Actually it's not quite as bad as that. Catch mitigates this situation by effectively maintaining the traditional separation between the implementation code and declarations. Internally the implementation code is protected by ```#ifdef```s and is conditionally compiled into only one translation unit. This translation unit is that one that ```#define```s ```CATCH_CONFIG_MAIN``` or ```CATCH_CONFIG_RUNNER```. Let's call this the main source file.
 
-As a result the main source file *does* compile the whole of Catch every time! So it makes sense to dedicate this file to *only* ```#define```-ing the identifier and ```#include```-ing Catch (and implementing the runner code, if you're doing that).

 ## Practical example
 Assume you have the `Factorial` function from the [tutorial](tutorial.md#top) in `factorial.cpp` (with forward declaration in `factorial.h`) and want to test it and keep the compile times down when adding new tests. Then you should have 2 files, `tests-main.cpp` and `tests-factorial.cpp`:

 Although this was a simple test it's been enough to demonstrate a few things about how Catch is used. Let's take a moment to consider those before we move on.
 
 1. All we did was ```#define``` one identifier and ```#include``` one header and we got everything - even an implementation of ```main()``` that will [respond to command line arguments](command-line.md#top). You can only use that ```#define``` in one implementation file, for (hopefully) obvious reasons. Once you have more than one file with unit tests in you'll just ```#include "catch.hpp"``` and go. Usually it's a good idea to have a dedicated implementation file that just has ```#define CATCH_CONFIG_MAIN``` and ```#include "catch.hpp"```. You can also provide your own implementation of main and drive Catch yourself (see [Supplying-your-own-main()](own-main.md#top)).
-2. We introduce test cases with the ```TEST_CASE``` macro. This macro takes one or two arguments - a free form test name and, optionally, one or more tags (for more see <a href="#test-cases-and-sections">Test cases and Sections</a>, ). The test name must be unique. You can run sets of tests by specifying a wildcarded test name or a tag expression. See the [command line docs](command-line.md#top) for more information on running tests.

See the [command line docs](command-line.md#top) for more information on running tests.
 3. The name and tags arguments are just strings. We haven't had to declare a function or method - or explicitly register the test case anywhere. Behind the scenes a function with a generated name is defined for you, and automatically registered using static registry classes. By abstracting the function name away we can name our tests without the constraints of identifier names.
 4. We write our individual test assertions using the ```REQUIRE``` macro. Rather than a separate macro for each type of condition we express the condition naturally using C/C++ syntax. Behind the scenes a simple set of expression templates captures the left-hand-side and right-hand-side of the expression so we can display the values in our test report. As we'll see later there _are_ other assertion macros - but because of this technique the number of them is drastically reduced.
