As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
- Avoid generic types in `ScriptPathAttributeGenerator`, this
means they won't be added to the `[AssemblyHasScripts]` attribute
and a `[ScriptPath]` attribute won't be added to the class.
Since generic classes can't be used as scripts they shouldn't use
those attributes, this also makes CSharpScript consider those types
invalid since they won't be added to the script/type map.
- Avoid generic types in `ScriptManagerBridge.LookupScriptsInAssembly`.
- Set `outMethodsDest` in `ScriptManagerBridge.UpdateScriptClassInfo`.
- Renamed `ConvertToX` to `ConvertToNativeX`.
- Renamed `ConvertToXObject` to `ConvertToX`.
- Renamed `ConvertToXManaged` to `ConvertToX`.
- Fix `Signal` name in bindings generator and csharp script.
Non-exhaustive list of case-sensitive renames:
GDExtension -> GDNative
GDNATIVE -> GDEXTENSION
gdextension -> gdnative
ExtensionExtension ->Extension (for where there was GDNativeExtension)
EXTENSION_EXTENSION ->EXTENSION (for where there was GDNATIVE_EXTENSION)
gdnlib -> gdextension
gdn_interface -> gde_interface
gdni -> gde_interface
This was a regression from 17b2838f39.
`MarshalUtils` was changed in the source generators to use
`ConvertTo<T>` and `CreateFrom<T>`, which don't support `GodotObject[]`
because it would need reflection.
As such, we need to keep the custom cases for `GodotObject[]` in
`MarshalUtils`.
- Exposes the properties of C# attribute so they can be accessed from
reflection, renaming them to PascalCase to follow .NET conventions.
- Added some documentation to the newly exposed members.
- Made attribute properties readonly to avoid giving the impression that
they could be modified.
This commit replaces most usages of `ConvertManagedObjectToVariant` and
`ConvertVariantToManagedObjectOfType`, by using the `Godot.Variant`
struct instead of `System.Object`.
The most notable change is to the `GetGodotPropertyDefaultValues` method
that's generated for scripts. The dictionary it returns now stores
`Godot.Variant` values.
Remaining usages are:
- The `DelegateUtils` class, for the serialization of closure display
classes during assembly reloading by the editor. These display classes
are compiler generated classes to store values captured by a closure.
Since it's generated by the compiler, the only way we have to access
the fields is through reflection. This leads to using `System.Object`.
- Converting parameters when invoking constructors from the engine.
This will be replaced with source generators in the future.
- Legacy support for old `GetGodotPropertyDefaultValues` return values.
We need to keep supporting the old version of this generated method
for some time. Otherwise, if loading a project built with the previous
version, it could lead to the loss of exported property values.
Ideally, we should remove this legacy support before a stable release.
Its two usages were:
- The Array `ICollection.CopyTo` implementation.
It's possible that this class shouldn't be implementing the
non-generic `ICollection`, but this commit doesn't change that.
The new implementation stores the elements as boxed `Variant` values.
- The `Variant.Obj` property.
I'm not sure if this property's existence is justified, but for now
I rewrote it as a simpler version of `ConvertVariantToManagedObject`.
- Removed `UnicodeAt`
- Removed `EndsWith`
- Removed `LPad` and `RPad`
- Deprecated `BeginsWith` in favor of `string.StartsWith`
- Deprecated `LStrip` and `RStrip` in favor of `string.TrimStart` and `string.TrimEnd`
- Remove `VariantSpanDisposer`, no need to dispose of the Variant Spans
since we are now borrowing the Variants instead of copying them.
- Remove `VariantSpanExtensions.Cleared` that was only used so the
Span was initialized for `VariantSpanDisposer` to know what to dispose.
- Fix stackalloc Spans to use constant VarArgsSpanThreshold
and avoid bound checks.
- Replaced `MD5Buffer`, `MD5Text`, `SHA256Buffer` and `SHA256Text` implementation to use the `System.Security.Cryptography` classes and avoid marshaling.
- Added `SHA1Buffer` and `SHA1Text`.
- Renamed `ToUTF8` to `ToUTF8Buffer`.
- Renamed `ToAscii` to `ToASCIIBuffer`.
- Added `ToUTF16Buffer` and `ToUTF32Buffer`.
- Added `GetStringFromUTF16` and `GetStringFromUTF32`.
- Renamed `IsValidInteger` to `IsValidInt`.
- Added `IsValidFileName`.
- Added `IsValidHexNumber`.
- Added support for IPv6 to `IsValidIPAddress`.
- Added `ValidateNodeName`.
- Updated the documentation of the `IsValid*` methods.
- Moved `GetBaseName` to keep methods alphabetically sorted.
- Removed `Length`, users should just use the Length property.
- Removed `Insert`, string already has a method with the same signature that takes precedence.
- Removed `Erase`.
- Removed `ToLower` and `ToUpper`, string already has methods with the same signature that take precedence.
- Removed `FindLast` in favor of `RFind`.
- Replaced `RFind` and `RFindN` implemenation with a ca ll to `string.LastIndexOf` to avoid marshaling.
- Added `LPad` and `RPad`.
- Added `StripEscapes`.
- Replaced `LStrip` and `RStrip` implementation with a call to `string.TrimStart` and `string.TrimEnd`.
- Added `TrimPrefix` and `TrimSuffix`.
- Renamed `OrdAt` to `UnicodeAt`.
- Added `CountN` and move the `caseSensitive` parameter of `Count` to the end.
- Added `Indent` and `Dedent`.
These callbacks are used for marshaling by callables and generic Godot
collections.
C# generics don't support specialization the way C++ templates do.
I knew NativeAOT could optimize away many type checks when the types
are known at compile time, but I didn't trust the JIT would do as good
a job, so I initially went with cached function pointers.
Well, it turns out the JIT is also very good at optimizing in this
scenario, so I'm changing the methods to do the conversion directly,
rather than returning a function pointer for the conversion.
The methods were moved to `VariantUtils`, and were renamed from
`GetFromVariantCallback/GetToVariantCallback` to `ConvertTo/CreateFrom`.
The new implementation looks like it goes through many `if` checks
at runtime to find the right branch for the type, but in practice it
works pretty much like template specialization. The JIT only generates
code for the relevant branch. Together with inlining, the result is
very close or the same as doing the conversion manually:
```cs
godot_variant variant;
int foo = variant.Int;
int bar = VariantUtils.ConvertTo<int>(variant);
```
If the type is a generic Godot collection, the conversion still goes
through a function pointer call.
The new code happens to be much shorter as well, with the file going
from 1057 lines to 407.
Side note: `Variant.cs` was mistakenly created in the wrong folder,
so I moved it to the `Core` folder.
