* Refactor cmake file to have GSL as an interface
CMake supports header only libraries as INTERFACE libraries. Using
interfaces libraries make is easier for users to use the library because
one just need to "link" agaisnt the library and necessary include paths,
definitions, flags... will be taken care of.
This commit creates a new interface library called GSL. It then add the
following things to the GSL library:
- compiler flags ex: (-std=c++14)
- definitions ex: _SCL_SECURE_NO_WARNINGS
- include paths ex: include/gsl
- natvis file
Another project can now have the GSL project as a git submodule and one
only need to add the two following lines to their project to use the
GSL.
add_subdirectory(GSL)
target_link_libraries(<some target> GSL)
After cmake 3.8.0 a lot of the logic can be simplified. Right now the
cmake file has an if for version checking, but when the minimun required
version is 3.8.0 one can just delete the branching and keep the simpler
version.
* Cut support for c++11
Compiling on GCC6.2 with only the c++11 flag will generate compilation
errors. For example some of the errors are related to the use of
enable_if_t which is a c++14 feature.
To avoid compilation errors this comiit removes c++11 support on linux.
* Refactor code that pulls unittest-cpp
Two minor changes:
- uses cmake to find a proper installation of git (in case user does not
have it on the path)
- checks for the CMakeLists file instead. This is needed for the build
itself and seems like a better way to do the checking
* Refactor tests so they show together on VS
This commit will make a VS geenrated project to group all tests under
GSL_tests
* Refactor tests configuration
This creates a test configuration interface and add all the previous
compiler options to that interface. compiler options are now sorted so
it is easier to find them, and also one per line, so that modifications
are easier to track from git.
Project files were not following the clang-format style. For people
using IDEs were clang-format is always run after a save this would
cause unwanted changes.
This commit only applies "clang-format -i" to files.
* Add value_type to span
Currently I'm working on project which involves a lot of `span`s and mocking via Google Mock. Unfortunately a lot of standard matchers requires `value_type` type definition inside container which `gsl::span` lacks.
This pull request add `value_type` type definition inside `gsl::span`
* Strip cv from value_type of span and span_iterator
* Added support of not_null<smart_ptr> comparison
* The return type of not_null comparison operators is determined using SFINAE
#474
* tests for gsl::not_null comparison were added
* not_null comparison tests were rewritten to compare pointers to objects located in the same array
* not_null<shared_ptr> comparison was simplified
* initializer_list overload returns by value to avoid lifetime issues
* generic overload uses expression SFINAE to work with any type that has member size() and operator[], which notably includes const/non-const vector and array.
* Add test coverage for const objects, rvalue initializer_lists, and constexpr usage.
Fixes#357.
* Improve const correctness in string_span
* Improve const correctness in bounds_tests.cpp and byte_tests.cpp
* Improve const correctness in span_tests.cpp
* Improve const correctness in utils_tests.cpp
* Use gsl::owner for dynamically allocated memory in string_span_tests.cpp
* Improve const correctness in string_span_tests.cpp
* Improve const correctness for strided_span_tests.cpp
* CI updates:
Travis: use cmake 3.7
Appveyor: Add .appveyor.yml config, test VS2013/VS2015/VS2017 x86/x64 Debug/Release.
* Drop VS2013 support from AppVeyor.
* GSL_LIKELY/_UNLIKELY always contextually convert their argument to bool.
* Add macro GSL_ASSUME(cond) to inform the optimizer that the predicate cond must hold.
* Reimplement Expects & Ensures as expressions for flexibility and correctness. (Think about "if (cond1) Expects(cond2); else goto fail;")
* Expects and Ensures GSL_ASSUME their predicate when GSL_UNENFORCED_ON_CONTRACT_VIOLATION is defined.
* add gsl::not_null operator<<
Hippomocks, which is a popular mocking engine for C++ uses operator<< on pointers and gets confused about gsl::not_null not having this operator.
* Update gsl
* Update README.md
edited link to the `gsl` include directory
* Update README.md
added `include` to the include path according to the directory structure
* constexpr all the things.
* remove operator=(const T&)
* it leaves *this in an invalid state if ensure_invariant fails
* implicitly converting the T to not_null and then assigning is in every way superior.
* simplify conversion from not_null<U> with constructor delegation.
* remove the converting assignment operator; again let the conversion constructor and self-assignment operator do the work.
* Cover the remaining pointer arithmetic operations as Wakely suggests in issue #447.
* Cleanup not_null conversions from null pointer constants:
* replace constructor that accepts T with constructor template that accepts U convertible to T
* remove deleted constructor that accepts int
* Attempts to initialize with nullptr, 0, 0L, 0LL, etc. all unambiguously select the deleted nullptr_t constructor.
Now that the STL respects /W4, this test that uses std::copy_n to copy a span of ints to a span of chars triggers "warning C4244: '=': conversion from 'int' to 'char', possible loss of data". Switch the source & destination spans to short and int to maintain the test's cross-type nature but without narrowing.
* Nest "gsl" directory inside a new "include" directory.
* Cleanup the _MSC_VER conditionals a bit; use constexpr on VS2017+.
* Don't #define noexcept on non-Microsoft implementations.
* Workaround VS2017 bug in multi_span. (Also implement == and != for static_bounds_dynamic_range_t because I'm an EoP semantic soundness snob.)
Fixes#441.
This patch provides a make_span function to simplify the
creation of spans until C++17 is available. In addition
this patch updates the unit tests to includes tests that
verify this new functionality.
This patch adds support for std::unique_ptr and
std::shared_ptr to the gsl::span
class instead of having to manually grab the pointer via
get().
For reference, this is part of the following issue:
https://github.com/Microsoft/GSL/issues/402
When turning on the following flags, several additional warnings
were generated, which have been cleaned up in this patch. The
flags included:
-Wextra
-Wpedantic
-Wconversion
-Wsign-conversion
-Wctor-dtor-privacy
-Wshadow
-Wnon-virtual-dtor
-Wold-style-cast
-Wcast-align
-Woverloaded-virtual
This patch fixes an overflow that was identified with
strict overflow warnings enabled, and optimizations
turned on

'make install' should install the GSL library (ie. the headers),
not the tests.
It still installs the UnitTest++ headers, but that will be more
complex to fix, as GSL just imports UnitTest++ as a git submodule,
and the install command propagates down to UnitTest++'s
CMakeLists.txt.
* Add test to demonstrate byte aliasing problem on g++ and clang++
* Add note about no-strict-aliasing flag in README
* Activate aliasing unit test and use -fno-strict-aliasing flag
