 yaml-cpp is a [YAML](http://www.yaml.org/) parser and emitter in C++ matching the [YAML 1.2 spec](http://www.yaml.org/spec/1.2/spec.html).
 
 To get a feel for how it can be used, see the [Tutorial](https://github.com/jbeder/yaml-cpp/wiki/Tutorial) or [How to Emit YAML](https://github.com/jbeder/yaml-cpp/wiki/How-To-Emit-YAML). For the old API (version < 0.5.0), see [How To Parse A Document](https://github.com/jbeder/yaml-cpp/wiki/How-To-Parse-A-Document-(Old-API)).

-[yaml-cpp 0.5.2](https://github.com/jbeder/yaml-cpp/releases/tag/release-0.5.2) has been released! This is a bug fix release.
+[yaml-cpp 0.6.0](https://github.com/jbeder/yaml-cpp/releases/tag/yaml-cpp-0.6.0) has been released! This release requires C++11, and no longer depends on Boost.
 
 [yaml-cpp 0.3.0](https://github.com/jbeder/yaml-cpp/releases/tag/release-0.3.0) is still available if you want the old API.
 
 **The old API will continue to be supported, and will still receive bugfixes!** The 0.3.x and 0.4.x versions will be old API releases, and 0.5.x and above will all be new API releases.

+## How to use
+Add yaml-cpp.natvis to your Visual C++ project like any other source file.  It will be included in the debug information, and improve debugger display on YAML::Node and contained types. 
+
+## Compatibility and Troubleshooting
+
+This has been tested for MSVC 2017. It is expected to be compatible with VS 2015 and VS 2019. If you have any problems, you can open an issue here: https://github.com/peterchen-cp/yaml-cpp-natvis

test/gmock-1.7.0/CHANGES

@@ -1,126 +0,0 @@
-Changes for 1.7.0:
-
-* All new improvements in Google Test 1.7.0.
-* New feature: matchers DoubleNear(), FloatNear(),
-  NanSensitiveDoubleNear(), NanSensitiveFloatNear(),
-  UnorderedElementsAre(), UnorderedElementsAreArray(), WhenSorted(),
-  WhenSortedBy(), IsEmpty(), and SizeIs().
-* Improvement: Google Mock can now be built as a DLL.
-* Improvement: when compiled by a C++11 compiler, matchers AllOf()
-  and AnyOf() can accept an arbitrary number of matchers.
-* Improvement: when compiled by a C++11 compiler, matchers
-  ElementsAreArray() can accept an initializer list.
-* Improvement: when exceptions are enabled, a mock method with no
-  default action now throws instead crashing the test.
-* Improvement: added class testing::StringMatchResultListener to aid
-  definition of composite matchers.
-* Improvement: function return types used in MOCK_METHOD*() macros can
-  now contain unprotected commas.
-* Improvement (potentially breaking): EXPECT_THAT() and ASSERT_THAT()
-  are now more strict in ensuring that the value type and the matcher
-  type are compatible, catching potential bugs in tests.
-* Improvement: Pointee() now works on an optional<T>.
-* Improvement: the ElementsAreArray() matcher can now take a vector or
-  iterator range as input, and makes a copy of its input elements
-  before the conversion to a Matcher.
-* Improvement: the Google Mock Generator can now generate mocks for
-  some class templates.
-* Bug fix: mock object destruction triggerred by another mock object's
-  destruction no longer hangs.
-* Improvement: Google Mock Doctor works better with newer Clang and
-  GCC now.
-* Compatibility fixes.
-* Bug/warning fixes.
-
-Changes for 1.6.0:
-
-* Compilation is much faster and uses much less memory, especially
-  when the constructor and destructor of a mock class are moved out of
-  the class body.
-* New matchers: Pointwise(), Each().
-* New actions: ReturnPointee() and ReturnRefOfCopy().
-* CMake support.
-* Project files for Visual Studio 2010.
-* AllOf() and AnyOf() can handle up-to 10 arguments now.
-* Google Mock doctor understands Clang error messages now.
-* SetArgPointee<> now accepts string literals.
-* gmock_gen.py handles storage specifier macros and template return
-  types now.
-* Compatibility fixes.
-* Bug fixes and implementation clean-ups.
-* Potentially incompatible changes: disables the harmful 'make install'
-  command in autotools.
-
-Potentially breaking changes:
-
-* The description string for MATCHER*() changes from Python-style
-  interpolation to an ordinary C++ string expression.
-* SetArgumentPointee is deprecated in favor of SetArgPointee.
-* Some non-essential project files for Visual Studio 2005 are removed.
-
-Changes for 1.5.0:
-
- * New feature: Google Mock can be safely used in multi-threaded tests
-   on platforms having pthreads.
- * New feature: function for printing a value of arbitrary type.
- * New feature: function ExplainMatchResult() for easy definition of
-   composite matchers.
- * The new matcher API lets user-defined matchers generate custom
-   explanations more directly and efficiently.
- * Better failure messages all around.
- * NotNull() and IsNull() now work with smart pointers.
- * Field() and Property() now work when the matcher argument is a pointer
-   passed by reference.
- * Regular expression matchers on all platforms.
- * Added GCC 4.0 support for Google Mock Doctor.
- * Added gmock_all_test.cc for compiling most Google Mock tests
-   in a single file.
- * Significantly cleaned up compiler warnings.
- * Bug fixes, better test coverage, and implementation clean-ups.
-
- Potentially breaking changes:
-
- * Custom matchers defined using MatcherInterface or MakePolymorphicMatcher()
-   need to be updated after upgrading to Google Mock 1.5.0; matchers defined
-   using MATCHER or MATCHER_P* aren't affected.
- * Dropped support for 'make install'.
-
-Changes for 1.4.0 (we skipped 1.2.* and 1.3.* to match the version of
-Google Test):
-
- * Works in more environments: Symbian and minGW, Visual C++ 7.1.
- * Lighter weight: comes with our own implementation of TR1 tuple (no
-   more dependency on Boost!).
- * New feature: --gmock_catch_leaked_mocks for detecting leaked mocks.
- * New feature: ACTION_TEMPLATE for defining templatized actions.
- * New feature: the .After() clause for specifying expectation order.
- * New feature: the .With() clause for for specifying inter-argument
-   constraints.
- * New feature: actions ReturnArg<k>(), ReturnNew<T>(...), and
-   DeleteArg<k>().
- * New feature: matchers Key(), Pair(), Args<...>(), AllArgs(), IsNull(),
-   and Contains().
- * New feature: utility class MockFunction<F>, useful for checkpoints, etc.
- * New feature: functions Value(x, m) and SafeMatcherCast<T>(m).
- * New feature: copying a mock object is rejected at compile time.
- * New feature: a script for fusing all Google Mock and Google Test
-   source files for easy deployment.
- * Improved the Google Mock doctor to diagnose more diseases.

-Google C++ Mocking Framework
-============================
-
-http://code.google.com/p/googlemock/
-
-Overview
---------
-
-Google's framework for writing and using C++ mock classes on a variety
-of platforms (Linux, Mac OS X, Windows, Windows CE, Symbian, etc).
-Inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s
-specifics in mind, it can help you derive better designs of your
-system and write better tests.
-
-Google Mock:
-
-- provides a declarative syntax for defining mocks,
-- can easily define partial (hybrid) mocks, which are a cross of real
-  and mock objects,
-- handles functions of arbitrary types and overloaded functions,
-- comes with a rich set of matchers for validating function arguments,
-- uses an intuitive syntax for controlling the behavior of a mock,
-- does automatic verification of expectations (no record-and-replay
-  needed),
-- allows arbitrary (partial) ordering constraints on
-  function calls to be expressed,
-- lets a user extend it by defining new matchers and actions.
-- does not use exceptions, and
-- is easy to learn and use.
-
-Please see the project page above for more information as well as the
-mailing list for questions, discussions, and development.  There is
-also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please
-join us!
-
-Please note that code under scripts/generator/ is from the cppclean
-project (http://code.google.com/p/cppclean/) and under the Apache
-License, which is different from Google Mock's license.
-
-Requirements for End Users
---------------------------
-
-Google Mock is implemented on top of the Google Test C++ testing
-framework (http://code.google.com/p/googletest/), and includes the
-latter as part of the SVN repositary and distribution package.  You
-must use the bundled version of Google Test when using Google Mock, or
-you may get compiler/linker errors.
-
-You can also easily configure Google Mock to work with another testing
-framework of your choice; although it will still need Google Test as
-an internal dependency.  Please read
-http://code.google.com/p/googlemock/wiki/ForDummies#Using_Google_Mock_with_Any_Testing_Framework
-for how to do it.
-
-Google Mock depends on advanced C++ features and thus requires a more
-modern compiler.  The following are needed to use Google Mock:
-
-### Linux Requirements ###
-
-These are the base requirements to build and use Google Mock from a source
-package (as described below):
-
-  * GNU-compatible Make or "gmake"
-  * POSIX-standard shell
-  * POSIX(-2) Regular Expressions (regex.h)
-  * C++98-standard-compliant compiler (e.g. GCC 3.4 or newer)
-
-### Windows Requirements ###
-
-  * Microsoft Visual C++ 8.0 SP1 or newer
-
-### Mac OS X Requirements ###
-
-  * Mac OS X 10.4 Tiger or newer
-  * Developer Tools Installed
-
-Requirements for Contributors
------------------------------
-
-We welcome patches.  If you plan to contribute a patch, you need to
-build Google Mock and its own tests from an SVN checkout (described
-below), which has further requirements:
-
-  * Automake version 1.9 or newer
-  * Autoconf version 2.59 or newer
-  * Libtool / Libtoolize
-  * Python version 2.3 or newer (for running some of the tests and
-    re-generating certain source files from templates)
-
-Getting the Source
-------------------
-
-There are two primary ways of getting Google Mock's source code: you
-can download a stable source release in your preferred archive format,
-or directly check out the source from our Subversion (SVN) repositary.
-The SVN checkout requires a few extra steps and some extra software
-packages on your system, but lets you track development and make
-patches much more easily, so we highly encourage it.
-
-### Source Package ###
-
-Google Mock is released in versioned source packages which can be
-downloaded from the download page [1].  Several different archive
-formats are provided, but the only difference is the tools needed to
-extract their contents, and the size of the resulting file.  Download
-whichever you are most comfortable with.
-
-  [1] http://code.google.com/p/googlemock/downloads/list
-
-Once downloaded expand the archive using whichever tools you prefer
-for that type.  This will always result in a new directory with the
-name "gmock-X.Y.Z" which contains all of the source code.  Here are
-some examples on Linux:
-
-  tar -xvzf gmock-X.Y.Z.tar.gz
-  tar -xvjf gmock-X.Y.Z.tar.bz2
-  unzip gmock-X.Y.Z.zip
-
-### SVN Checkout ###
-
-To check out the main branch (also known as the "trunk") of Google
-Mock, run the following Subversion command:
-
-  svn checkout http://googlemock.googlecode.com/svn/trunk/ gmock-svn
-
-If you are using a *nix system and plan to use the GNU Autotools build
-system to build Google Mock (described below), you'll need to
-configure it now.  Otherwise you are done with getting the source
-files.
-
-To prepare the Autotools build system, enter the target directory of
-the checkout command you used ('gmock-svn') and proceed with the
-following command:
-
-  autoreconf -fvi
-
-Once you have completed this step, you are ready to build the library.
-Note that you should only need to complete this step once.  The
-subsequent 'make' invocations will automatically re-generate the bits
-of the build system that need to be changed.
-
-If your system uses older versions of the autotools, the above command
-will fail.  You may need to explicitly specify a version to use.  For
-instance, if you have both GNU Automake 1.4 and 1.9 installed and
-'automake' would invoke the 1.4, use instead:
-
-  AUTOMAKE=automake-1.9 ACLOCAL=aclocal-1.9 autoreconf -fvi
-
-Make sure you're using the same version of automake and aclocal.
-
-Setting up the Build
---------------------
-
-To build Google Mock and your tests that use it, you need to tell your
-build system where to find its headers and source files.  The exact
-way to do it depends on which build system you use, and is usually
-straightforward.
-
-### Generic Build Instructions ###
-
-This section shows how you can integrate Google Mock into your
-existing build system.
-
-Suppose you put Google Mock in directory ${GMOCK_DIR} and Google Test
-in ${GTEST_DIR} (the latter is ${GMOCK_DIR}/gtest by default).  To
-build Google Mock, create a library build target (or a project as
-called by Visual Studio and Xcode) to compile
-
-  ${GTEST_DIR}/src/gtest-all.cc and ${GMOCK_DIR}/src/gmock-all.cc
-
-with
-
-  ${GTEST_DIR}/include and ${GMOCK_DIR}/include
-
-in the system header search path, and
-
-  ${GTEST_DIR} and ${GMOCK_DIR}
-
-in the normal header search path.  Assuming a Linux-like system and gcc,
-something like the following will do:
-
-  g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-      -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-      -pthread -c ${GTEST_DIR}/src/gtest-all.cc
-  g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-      -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-      -pthread -c ${GMOCK_DIR}/src/gmock-all.cc
-  ar -rv libgmock.a gtest-all.o gmock-all.o
-
-(We need -pthread as Google Test and Google Mock use threads.)
-
-Next, you should compile your test source file with
-${GTEST_DIR}/include and ${GMOCK_DIR}/include in the header search
-path, and link it with gmock and any other necessary libraries:
-
-  g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \
-      -pthread path/to/your_test.cc libgmock.a -o your_test
-
-As an example, the make/ directory contains a Makefile that you can
-use to build Google Mock on systems where GNU make is available
-(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
-Mock's own tests.  Instead, it just builds the Google Mock library and
-a sample test.  You can use it as a starting point for your own build
-script.
-
-If the default settings are correct for your environment, the
-following commands should succeed:
-
-  cd ${GMOCK_DIR}/make
-  make
-  ./gmock_test
-
-If you see errors, try to tweak the contents of make/Makefile to make
-them go away.  There are instructions in make/Makefile on how to do
-it.
-
-### Windows ###
-
-The msvc/2005 directory contains VC++ 2005 projects and the msvc/2010
-directory contains VC++ 2010 projects for building Google Mock and
-selected tests.
-
-Change to the appropriate directory and run "msbuild gmock.sln" to
-build the library and tests (or open the gmock.sln in the MSVC IDE).
-If you want to create your own project to use with Google Mock, you'll
-have to configure it to use the gmock_config propety sheet.  For that:
-
- * Open the Property Manager window (View | Other Windows | Property Manager)
- * Right-click on your project and select "Add Existing Property Sheet..."
- * Navigate to gmock_config.vsprops or gmock_config.props and select it.
- * In Project Properties | Configuration Properties | General | Additional
-   Include Directories, type <path to Google Mock>/include.
-
-Tweaking Google Mock
---------------------
-
-Google Mock can be used in diverse environments.  The default
-configuration may not work (or may not work well) out of the box in
-some environments.  However, you can easily tweak Google Mock by
-defining control macros on the compiler command line.  Generally,
-these macros are named like GTEST_XYZ and you define them to either 1
-or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below.  For a complete list,
-see file ${GTEST_DIR}/include/gtest/internal/gtest-port.h.
-
-### Choosing a TR1 Tuple Library ###
-
-Google Mock uses the C++ Technical Report 1 (TR1) tuple library
-heavily.  Unfortunately TR1 tuple is not yet widely available with all
-compilers.  The good news is that Google Test 1.4.0+ implements a
-subset of TR1 tuple that's enough for Google Mock's need.  Google Mock
-will automatically use that implementation when the compiler doesn't
-provide TR1 tuple.
-
-Usually you don't need to care about which tuple library Google Test
-and Google Mock use.  However, if your project already uses TR1 tuple,
-you need to tell Google Test and Google Mock to use the same TR1 tuple
-library the rest of your project uses, or the two tuple
-implementations will clash.  To do that, add
-
-  -DGTEST_USE_OWN_TR1_TUPLE=0
-
-to the compiler flags while compiling Google Test, Google Mock, and
-your tests.  If you want to force Google Test and Google Mock to use
-their own tuple library, just add
-
-  -DGTEST_USE_OWN_TR1_TUPLE=1
-
-to the compiler flags instead.
-
-If you want to use Boost's TR1 tuple library with Google Mock, please
-refer to the Boost website (http://www.boost.org/) for how to obtain
-it and set it up.
-
-### As a Shared Library (DLL) ###
-
-Google Mock is compact, so most users can build and link it as a static
-library for the simplicity.  Google Mock can be used as a DLL, but the
-same DLL must contain Google Test as well.  See Google Test's README
-file for instructions on how to set up necessary compiler settings.
-
-### Tweaking Google Mock ###
-
-Most of Google Test's control macros apply to Google Mock as well.
-Please see file ${GTEST_DIR}/README for how to tweak them.
-
-Upgrading from an Earlier Version
----------------------------------
-
-We strive to keep Google Mock releases backward compatible.
-Sometimes, though, we have to make some breaking changes for the
-users' long-term benefits.  This section describes what you'll need to
-do if you are upgrading from an earlier version of Google Mock.
-
-### Upgrading from 1.1.0 or Earlier ###
-
-You may need to explicitly enable or disable Google Test's own TR1
-tuple library.  See the instructions in section "Choosing a TR1 Tuple
-Library".
-
-### Upgrading from 1.4.0 or Earlier ###
-
-On platforms where the pthread library is available, Google Test and
-Google Mock use it in order to be thread-safe.  For this to work, you
-may need to tweak your compiler and/or linker flags.  Please see the
-"Multi-threaded Tests" section in file ${GTEST_DIR}/README for what
-you may need to do.
-
-If you have custom matchers defined using MatcherInterface or
-MakePolymorphicMatcher(), you'll need to update their definitions to
-use the new matcher API [2].  Matchers defined using MATCHER() or
-MATCHER_P*() aren't affected.
-
-  [2] http://code.google.com/p/googlemock/wiki/CookBook#Writing_New_Monomorphic_Matchers,
-      http://code.google.com/p/googlemock/wiki/CookBook#Writing_New_Polymorphic_Matchers
-
-Developing Google Mock
-----------------------
-
-This section discusses how to make your own changes to Google Mock.
-
-### Testing Google Mock Itself ###
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you'll need Autotools.  First, make sure you have followed
-the instructions in section "SVN Checkout" to configure Google Mock.
-Then, create a build output directory and enter it.  Next,
-
-  ${GMOCK_DIR}/configure  # Standard GNU configure script, --help for more info
-
-Once you have successfully configured Google Mock, the build steps are
-standard for GNU-style OSS packages.
-
-  make        # Standard makefile following GNU conventions
-  make check  # Builds and runs all tests - all should pass.
-
-Note that when building your project against Google Mock, you are building
-against Google Test as well.  There is no need to configure Google Test
-separately.
-
-### Regenerating Source Files ###
-
-Some of Google Mock's source files are generated from templates (not
-in the C++ sense) using a script.  A template file is named FOO.pump,
-where FOO is the name of the file it will generate.  For example, the
-file include/gmock/gmock-generated-actions.h.pump is used to generate

-Normally you don't need to worry about regenerating the source files,
-unless you need to modify them.  In that case, you should modify the
-corresponding .pump files instead and run the 'pump' script (for Pump
-is Useful for Meta Programming) to regenerate them.  You can find
-pump.py in the ${GTEST_DIR}/scripts/ directory.  Read the Pump manual
-[3] for how to use it.
