Changelog

All changes to this project will be documented in this file. The format is based on Keep a Changelog.

[0.1.0a19]

Added

tnt::unroll on types/TypeUtils.hpp, which emulates a partially unrolled loop.
json/JsonEnum.hpp, which adds support for automatically generating json bindings for desired enum types on request. For enabling automatic enum bindings, please modify tnt::enum_traits<T> from types/EnumTraits.hpp to true for your enum T like this:

    enum my_enum { /* some custom values */ };

    #include "types/EnumTraits.hpp" // needed for tnt::enum_traits

    template <>
    struct tnt::enum_traits<my_enum>
    {
        inline static constexpr my_enum count = my_enum::count; // change this if your enum doesn't have count at the end as a "sentinel"
        inline static constexpr bool jsonable = true;
    };

tnt::enum_sentinel<T>, a variable template that signalises "end of parsing" to enum-stringifying functions on mirror/Light.hpp. It can be specialised for your custom enums, and it defaults to T::count.
tnt::enum_name for getting a string representation of an enum's name either at compile time or run time.
tnt::enum_value for getting an concrete enum value from a string representation either at compile time or run time.
Support for tnt::task<void>.
mirror/Light.hpp which contains some basic reflection facilities. tnt::type_name and tnt::value_name now live there.
tnt::conceptify on types/TypeUtils.hpp, which helps convert simple type traits to concepts without you needing to write requires.

Changed

Reduced template instantiations on the new type lists implementation. You can find them on types/TypeLists.hpp.
Improved tnt::range to cover some corner cases.
tnt::enums now returns an array of pairs containing the name and the value of the enum.
tnt::Vector is now trivially default constructible. Also the constructor which has a single parameter is now explicit.
include/json/*'s folder files now have a corresponding source file on src/json. Also the "registration" technique is changed, but shouldn't affect the code that uses these files.
tnt::doo::system_base<T>::clear now works even if T doesn't provide a clear method by calling remove on each object on T::active. Also tnt::doo::system doesn't require types to provide a clear method anymore.
Methods of tnt::system<T> are now conditionally noexcept depending on the implementation of these methods on T.

Deprecated

tnt::Expected. Use tnt::expected from the same file instead as it offers exceptionless error handling and constexpr usage.

Removed

Old typelists implementation. It is replaced by the implementation that was previously found on folder exp.
[[deprecated]] functions on tnt::doo::physics_sys.

[0.1.0a18]

Added

operator== for tnt::bit_mask types.
utils/SDL_forward.hpp, which forward-declares some opaque SDL structs.
tnt::Vector now is move assignable.
tnt::value_name which returns a string representation of the value passed as a template parameter. It can be especially useful when used with enums.
Conversion operator from tnt::basic_hashed_string<Char> to std::basic_string_view<Char>.

Fixed

Some warnings related to the naming of some local variables.

Changed

Operators overloaded for tnt::bit_mask are now marked noexcept.
Separated the documentation part of the build from the rest. See cmake/Doxygen.cmake.
pcg/Random.hpp now has a corresponding source file.
Rewrote tnt::generator<T> to allow custom allocator support.
Minor quality of life improvements for tnt::generator<T> and tnt::task<T>.

[0.1.0a17]

Added

{fmt} support for tnt::type_info. See format/FormatedTypeInfo.hpp.
Support for the function from core/Graphics on Lua (table tnt:gfx). There is a new entry on tnt::lua::lib named graphics and some entries now have an updated value.
tnt::hashed_string, a non-mutable string with a pre-computed hash value on types/HashedString.hpp. std::hash (types/HashedString.hpp) and fmt::formatter (format/FormatedHashString.hpp) specialisations are provided.

Fixed

tnt::type_info::name() will now correctly show the type name stored.

Changed

tnt::type_info::operator== is now [[nodiscard]] to avoid accidentally using comparing instead of assignment.
tnt::type_info::name() will now return a std::string_view.
tnt::type_info is now final to avoid unintended usage.
tnt::type_id will not strip const& from the type name anymore.
Fixed warnings about tnt::doo::physics_sys::addForce being used on tnt::doo::steering_sys.
tnt::AudioPlayer now contains a pointer to the audio cache and one to the sfx cache.
tnt::Snipper, tnt::vfs_handle and tnt::vfs::* now use std:unordered_map.
tnt::Snipper, tnt::vfs_handle, tnt::vfs::*, tnt::asset_cache pre-defined specialisations now use tnt::hashed_string::hash_type as key.
Updated extra/.editorconfigto match the style used on the codebase.

Removed

physics folder, it was unused.

[0.1.0a16]

Added

tnt::type_name on TypeInfo.hpp if you need only the name of a type. tnt::operator<< for tnt::type_info so that it can be used with std::cout.
tnt::Vector::operator* with float as first argument, making some code easier to read.
tnt::physics_sys::force, that stores the force being applied to the objects on a certain moment. Related functions are updated accordingly.
tnt::is_debug_v and tnt::is_release_v on utils/Traits.hpp.
extra/tnt.natvis will be installed when building the install target.
utils/FLogger.hpp, which adds support for writing log output to a file by using functions on tnt::logger.
tnt::lua::registerLoader to add the TnT modules loader to the given lua state.
tnt::drawCircle and tnt::fillCircle on core/Graphics.
Deduction guides for classes on types/ScopeUtils.hpp.

Changed

Updated tnt::type_info and tnt::type_id<T> to work without friend.
tnt::physics_sys::AddForce and tnt::physics_sys::addGlobalForce are no longer profiled.
tnt::ImGui::WindowFlags is now 8 bit.
tnt::logger will now print the logging message type from ERROR: to [ERROR] to provide more readable output.
Moved tnt::logger::printable to namespace detail.
TnT libraries on Lua now MUST be required when used with tnt::scripts_sys from the Data Oriented ECS. Otherwise, the good ol' lua::load* functions are still available for use.
The third argument of tnt::scripts_sys::add_object, since TnT libraries can now be required from a Lua script.
tnt::crtp<T>::super is now protected.
Functions on core/Graphics are now marked as noexcept.

Fixed

Small tweaks.
Some incorrect things on exp/TypeListsv2.hpp.
Some incorrect things on doo_ecs/System.hpp.

Deprecated

tnt::physics_sys::addForce and tnt::physics_sys::addGlobalForce. Instead, just add the desired force to the tnt::physics_sys::force[id] and tnt::physics_sys::totalForce variables accordingly.

Removed

tnt::physics_sys::resolveVelocity and tnt::physics_sys::resolveInterpenetration. Use tnt::physics_sys::resolve instead.
tnt::crtp<T>::super. It gave issues when assigning a derived class. Use tnt::crtp<T>::base instead.

[0.1.0a15]

Added

tnt::y_comb on types/TypeUtils.hpp.
tnt::vfs_handle if you want to have separate virtual file systems. It is thread-safe, like the functions on tnt::vfs will be soon.
tnt::crtp<T>::super, which is the same as calling tnt::crtp<T>::base().
doo_ecs/System.hpp, which contains some utilities related to Data Oriented ECS systems.
utils/Bench.hpp which will replace utils/Benchmark.hpp.
tnt::sized_any<S>::operator bool to check the validity of the content of the any type.

Changed

tnt::crtp<T> is now default constructible and constexpr-ready.
TypeUtils.hpp is now moved on folder types.
PROFILE_FUNCTION now works with the three major compilers.
tnt::any is now tnt::sized_any<S> where S denotes the size of the storage for the any. It is deduced by default or can be set by the user. If you want to use different any objects with different sizes on an array/vector, use tnt::any which is equal to tnt::sized_any<(std::size_t)-1> and has a default size.

Deprecated

utils/Benchmark.hpp, but you should still use it, until utils/Bench.hpp is finished.

        "script": {
            "file": "script.lua",
            // optional, core by default.
            "libs": ["core", "math"]
        }
    }

Exported tnt::lua::load.
exe linked with TnT.dll crash randomly. NOTE that if you need to use the Data Oriented ECS (you normally need) and the Lua bindings for the Data Oriented ECS (src/tolua/LuaDooEcs.cpp), you have to build the source files on the src/doo_ecs folder together with your executable.

Changed

tnt::lua::load now needs std::span<const tnt::lua::lib> as an argument.
tnt::sparse_iterator's explicit ctor now accepts a tnt::sparse_set<T> const& instead of tnt::sparse_set<T> const*.

Now ImGui widgets require std::size_t for their id rather than long long, so that the id is not negative and it is compatible with std::hash.
The title on ImGui's windows is now more centered.
tnt::ImGui::checkbox() now doesn't need to have an id, x and y, because it is drawn on the window. Just a window where to draw it, the text to draw to it and a bool *value. The same with tnt::ImGui::button() and tnt::ImGui::menu().
tnt::ImGui::progress_bar() now has an offset between it's body and it's filled part and doesn't need x and y as parameter, but needs a text to draw on its side.
