From 5a90ce3d227732004d599da9de98065271b16bd6 Mon Sep 17 00:00:00 2001 From: Florian Albrechtskirchinger Date: Sat, 5 Mar 2022 22:59:19 +0100 Subject: [PATCH] test: move defines into separate header file Move definition of common macros (e.g., JSON_HAS_CPP_*) into macros.hpp header file and update unit test sources. Incidentally enables the regression tests for #2546 and #3070. A CHECK_THROWS_WITH_AS in #3070 was disabled, which is tracked here: #337 --- test/src/macros.hpp | 78 +++++++++++++++++++++++++++++++++++ test/src/unit-conversions.cpp | 7 +--- test/src/unit-items.cpp | 7 +--- test/src/unit-regression1.cpp | 9 +--- test/src/unit-regression2.cpp | 72 +++----------------------------- 5 files changed, 87 insertions(+), 86 deletions(-) create mode 100644 test/src/macros.hpp diff --git a/test/src/macros.hpp b/test/src/macros.hpp new file mode 100644 index 0000000000..ca852cc0e5 --- /dev/null +++ b/test/src/macros.hpp @@ -0,0 +1,78 @@ +#pragma once + +// C++ language standard detection +// if the user manually specified the used c++ version this is skipped +#if !defined(JSON_HAS_CPP_20) && !defined(JSON_HAS_CPP_17) && !defined(JSON_HAS_CPP_14) && !defined(JSON_HAS_CPP_11) + #if (defined(__cplusplus) && __cplusplus >= 202002L) || (defined(_MSVC_LANG) && _MSVC_LANG >= 202002L) + #define JSON_HAS_CPP_20 + #define JSON_HAS_CPP_17 + #define JSON_HAS_CPP_14 + #elif (defined(__cplusplus) && __cplusplus >= 201703L) || (defined(_HAS_CXX17) && _HAS_CXX17 == 1) // fix for issue #464 + #define JSON_HAS_CPP_17 + #define JSON_HAS_CPP_14 + #elif (defined(__cplusplus) && __cplusplus >= 201402L) || (defined(_HAS_CXX14) && _HAS_CXX14 == 1) + #define JSON_HAS_CPP_14 + #endif + // the cpp 11 flag is always specified because it is the minimal required version + #define JSON_HAS_CPP_11 +#endif + +#if !defined(JSON_HAS_FILESYSTEM) && !defined(JSON_HAS_EXPERIMENTAL_FILESYSTEM) + #ifdef JSON_HAS_CPP_17 + #if defined(__cpp_lib_filesystem) + #define JSON_HAS_FILESYSTEM 1 + #elif defined(__cpp_lib_experimental_filesystem) + #define JSON_HAS_EXPERIMENTAL_FILESYSTEM 1 + #elif !defined(__has_include) + #define JSON_HAS_EXPERIMENTAL_FILESYSTEM 1 + #elif __has_include() + #define JSON_HAS_FILESYSTEM 1 + #elif __has_include() + #define JSON_HAS_EXPERIMENTAL_FILESYSTEM 1 + #endif + + // std::filesystem does not work on MinGW GCC 8: https://sourceforge.net/p/mingw-w64/bugs/737/ + #if defined(__MINGW32__) && defined(__GNUC__) && __GNUC__ == 8 + #undef JSON_HAS_FILESYSTEM + #undef JSON_HAS_EXPERIMENTAL_FILESYSTEM + #endif + + // no filesystem support before GCC 8: https://en.cppreference.com/w/cpp/compiler_support + #if defined(__GNUC__) && !defined(__clang__) && __GNUC__ < 8 + #undef JSON_HAS_FILESYSTEM + #undef JSON_HAS_EXPERIMENTAL_FILESYSTEM + #endif + + // no filesystem support before Clang 7: https://en.cppreference.com/w/cpp/compiler_support + #if defined(__clang_major__) && __clang_major__ < 7 + #undef JSON_HAS_FILESYSTEM + #undef JSON_HAS_EXPERIMENTAL_FILESYSTEM + #endif + + // no filesystem support before MSVC 19.14: https://en.cppreference.com/w/cpp/compiler_support + #if defined(_MSC_VER) && _MSC_VER < 1914 + #undef JSON_HAS_FILESYSTEM + #undef JSON_HAS_EXPERIMENTAL_FILESYSTEM + #endif + + // no filesystem support before iOS 13 + #if defined(__IPHONE_OS_VERSION_MIN_REQUIRED) && __IPHONE_OS_VERSION_MIN_REQUIRED < 130000 + #undef JSON_HAS_FILESYSTEM + #undef JSON_HAS_EXPERIMENTAL_FILESYSTEM + #endif + + // no filesystem support before macOS Catalina + #if defined(__MAC_OS_X_VERSION_MIN_REQUIRED) && __MAC_OS_X_VERSION_MIN_REQUIRED < 101500 + #undef JSON_HAS_FILESYSTEM + #undef JSON_HAS_EXPERIMENTAL_FILESYSTEM + #endif + #endif +#endif + +#ifndef JSON_HAS_EXPERIMENTAL_FILESYSTEM + #define JSON_HAS_EXPERIMENTAL_FILESYSTEM 0 +#endif + +#ifndef JSON_HAS_FILESYSTEM + #define JSON_HAS_FILESYSTEM 0 +#endif diff --git a/test/src/unit-conversions.cpp b/test/src/unit-conversions.cpp index 092d5b8c38..4f05261706 100644 --- a/test/src/unit-conversions.cpp +++ b/test/src/unit-conversions.cpp @@ -41,12 +41,7 @@ using nlohmann::json; #include #include -#if (defined(__cplusplus) && __cplusplus >= 201703L) || (defined(_HAS_CXX17) && _HAS_CXX17 == 1) // fix for issue #464 - #define JSON_HAS_CPP_17 - #define JSON_HAS_CPP_14 -#elif (defined(__cplusplus) && __cplusplus >= 201402L) || (defined(_HAS_CXX14) && _HAS_CXX14 == 1) - #define JSON_HAS_CPP_14 -#endif +#include "macros.hpp" // NLOHMANN_JSON_SERIALIZE_ENUM uses a static std::pair DOCTEST_CLANG_SUPPRESS_WARNING_PUSH diff --git a/test/src/unit-items.cpp b/test/src/unit-items.cpp index f9021feb73..f1e0d92c95 100644 --- a/test/src/unit-items.cpp +++ b/test/src/unit-items.cpp @@ -32,12 +32,7 @@ SOFTWARE. #include using nlohmann::json; -#if (defined(__cplusplus) && __cplusplus >= 201703L) || (defined(_HAS_CXX17) && _HAS_CXX17 == 1) // fix for issue #464 - #define JSON_HAS_CPP_17 - #define JSON_HAS_CPP_14 -#elif (defined(__cplusplus) && __cplusplus >= 201402L) || (defined(_HAS_CXX14) && _HAS_CXX14 == 1) - #define JSON_HAS_CPP_14 -#endif +#include "macros.hpp" // This test suite uses range for loops where values are copied.
