CI: fix "JSON_MultipleHeaders" option spelling (#3555) 2022-06-25 13:38:39 +02:00
Florian Albrechtskirchinger 39e27684ea
Use DOCTEST_* compiler macros and suppress pragmas warning (#3550)
Use DOCTEST_* macros in place of predefined compiler macros for compiler
detection and version checks.

The suppression of warning -Wrange-loop-construct in unit-items.cpp
causes GCC<11 to warn about pragmas. Suppressed by adding a version
check.

Use `std::iterator_traits` to extract `iterator_category` (#3544)
* Use `std::iterator_traits` to extract `iterator_category`

In third-party STL implementations, `array_t::iterator` might be a pointer (e.g., `vector` in [EASTL](https://github.com/electronicarts/EASTL)) rather than a class, in which case directly using `array_t::iterator::iterator_category` is invalid. This commit fixes it with `std::iterator_traits`, which handles pointers correctly.

* add the changes to the single-header version

Implement support for string_view (attempt no. 3) (#3423)
* Add key_compare member to ordered_map

* Replace == with key_compare in ordered_map

* Expose the actual comparison function used by object_t

nlohmann::ordered_map uses a different comparison function than the one
provided via template parameter.
* Introduce a type trait to detect if object_t has a key_compare member.
* Rename object_comparator_t to default_object_comparator_t.
* Add object_comparator_t to be conditionally defined as
  object_t::key_compare, if available, or default_object_comparator_t
  otherwise.
* Update the documentation accordingly.

Co-authored-by: Niels Lohmann <niels.lohmann@gmail.com>

* Add type traits to check if a type is usable as object key

Add type trait to check:
* if a type is a specialization of a template.
* if a type is a json_pointer.
* if a type is a basic_json::{const_,}iterator.
* if two types are comparable using a given comparison functor.
* if a type is comparable to basic_json::object_t::key_type.
* if a type has a member type is_transparent.
* if a type is usable as object key.
* if a type has an erase() function accepting a given KeyType.

* Rework basic_json element access to accept more key types

Rework basic_json element access member functions and operators to
accept any type that meets the requirements defined by type trait
detail::is_usable_as_key_type.

Member functions and operators:
* at()
* operator[]
* value()
* erase()
* find()
* count()
* contains()

Update documentation to reflect these changes.

Add unit tests to excercise the new functions using std::string_view.

Restore disabled check for #3070 (except on MSVC) (#3421)
Restore the previously disabled check for regression #3070 on all
compilers but MSVC.

To summarize the issue:
Given namespace fs = std::filesystem.
On MSVC attempting to construct an fs::path from json results in an
ambiguous overload resolution because fs::path can be constructed from
both a std::string as well as another fs::path.
To the best of my knowledge there is no way to fix an ambiguous overload
situation involving a type we do not control and with json implicitly
converting to both std::string and fs::path.

Re-enabling the check where it compiles and keeping it disabled for MSVC
is the best we can do.

Closes #3377 and #3382.
