One Copyright Update to rule them all 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".

New GDScript tokenizer and parser Sometimes to fix something you have to break it first. This get GDScript mostly working with the new tokenizer and parser but a lot of things isn't working yet. It compiles and it's usable, and that should be enough for now. Don't worry: other huge commits will come after this.

#include "gdscript_analyzer.h"
Style: Harmonize header includes in modules This applies our existing style guide, and adds a new rule to that style guide for modular components such as platform ports and modules: Includes from the platform port or module ("local" includes) should be listed first in their own block using relative paths, before Godot's "core" includes which use "absolute" (project folder relative) paths, and finally thirdparty includes. Includes in `#ifdef`s come after their relevant section, i.e. the overall structure is: - Local includes * Conditional local includes - Core includes * Conditional core includes - Thirdparty includes * Conditional thirdparty includes

Clean up ProjectConverter3To4 architecture, move renames map to separate file This allows properly limiting what features depend on the RegEx module (doing the actual conversion) and what features only require the renames data (GDScript suggestions). Also better excludes the conversion command line options when actually disabling deprecated code. Fixes #73029.

GDScript: Refactor builtin functions They are now called "utility functions" to avoid confusion with methods of builtin types, and be consistent with the naming in Variant. Core utility functions are now available in GDScript. The ones missing in core are added specifically to GDScript as helpers for convenience. Some functions were remove when there are better ways to do, reducing redundancy and cleaning up the global scope.

GDScript: Add warnings that are set to error by default - Adds a list of default levels for all warning so they can be set individually. - Add warnings set by default to error for: - Using `get_node()` without `@onready`. - Using `@onready` together with `@export`. - Inferring a static type with a Variant value. - Overriding a native engine method. - Adjust how annotations to ignore warnings are treated so they also apply to method parameters. - Clean up a bit how ignored warnings are set. There were two sets but only one was actually being used. - Set all warnings to the `WARN` level for tests, so they they can be properly tested. - Fix enum types in native methods signatures being set to `int`. - Fix native enums being treated as Dictionary by mistake. - Make name of native enum types use the class they are defined in, not the direct super class of the script. This ensures they are always equal even when coming from different sources. - Fix error for signature mismatch that was only showing the first default argument as having a default. Now it shows for all.

GDScript: add errors when calling unimplemented virtual functions This PR does a small refactor of how method flags are handled in the GDScript analyzer. This way, it adds support for the analyzer to use any of MethodInfo's flags, where previously it could only use METHOD_FLAG_STATIC and METHOD_FLAG_VARARG. As a side-effect, this also normalizes behavior between editor and release templates, which fixes #76938. The tests added also brought a different issue to light, where using `super()` appears to generate a return variable discarded on calling super's _init(), which doesn't have a return value. This should be tackled in a different PR, which will have to change the output of this PR's tests.

There were two sets but only one was actually being used. - Set all warnings to the `WARN` level for tests, so they they can be properly tested. - Fix enum types in native methods signatures being set to `int`. - Fix native enums being treated as Dictionary by mistake. - Make name of native enum types use the class they are defined in, not the direct super class of the script. This ensures they are always equal even when coming from different sources. - Fix error for signature mismatch that was only showing the first default argument as having a default.

GDScript: Add warnings that are set to error by default - Adds a list of default levels for all warning so they can be set individually. - Add warnings set by default to error for: - Using `get_node()` without `@onready`. - Using `@onready` together with `@export`. - Inferring a static type with a Variant value. - Overriding a native engine method. - Adjust how annotations to ignore warnings are treated so they also apply to method parameters. - Clean up a bit how ignored warnings are set. There were two sets but only one was actually being used. - Set all warnings to the `WARN` level for tests, so they they can be properly tested. - Fix enum types in native methods signatures being set to `int`. - Fix native enums being treated as Dictionary by mistake. - Make name of native enum types use the class they are defined in, not the direct super class of the script. This ensures they are always equal even when coming from different sources. - Fix error for signature mismatch that was only showing the first default argument as having a default. Now it shows for all.

GDScript: add errors when calling unimplemented virtual functions This PR does a small refactor of how method flags are handled in the GDScript analyzer. This way, it adds support for the analyzer to use any of MethodInfo's flags, where previously it could only use METHOD_FLAG_STATIC and METHOD_FLAG_VARARG. As a side-effect, this also normalizes behavior between editor and release templates, which fixes #76938. The tests added also brought a different issue to light, where using `super()` appears to generate a return variable discarded on calling super's _init(), which doesn't have a return value. This should be tackled in a different PR, which will have to change the output of this PR's tests.

Replace most uses of Map by HashMap * Map is unnecessary and inefficient in almost every case. * Replaced by the new HashMap. * Renamed Map to RBMap and Set to RBSet for cases that still make sense (order matters) but use is discouraged. There were very few cases where replacing by HashMap was undesired because keeping the key order was intended. I tried to keep those (as RBMap) as much as possible, but might have missed some. Review appreciated!

GDScript: add errors when calling unimplemented virtual functions This PR does a small refactor of how method flags are handled in the GDScript analyzer. This way, it adds support for the analyzer to use any of MethodInfo's flags, where previously it could only use METHOD_FLAG_STATIC and METHOD_FLAG_VARARG. As a side-effect, this also normalizes behavior between editor and release templates, which fixes #76938. The tests added also brought a different issue to light, where using `super()` appears to generate a return variable discarded on calling super's _init(), which doesn't have a return value. This should be tackled in a different PR, which will have to change the output of this PR's tests.

GDScript: Check if method signature matches the parent To guarantee polymorphism, a method signature must be compatible with the parent. This checks if: 1. Return type is the same. 2. The subclass method takes at least the same amount of parameters. 3. The matching parameters have the same type. 4. If the subclass takes more parameters, all of the extra ones have a default value. 5. If the superclass has default values, so must have the subclass. There's a few test cases to ensure this holds up.

GDScript: do not warn of return value discarded for super() inside _init() DO NOT BATCH MERGE WITH #77324, WILL RESULT IN BROKEN CI Currently, calling super() inside _init() throws a RETURN_VALUE_DISCARDED warning. The analyzer identifies super() as being a constructor, which therefore returns an object of the relevant class. However, super() isn't really a constructor by itself: in this case, it is _part_ of the constructor, and so doesn't "return" a value. A test case for this is already in #77324, which contains the warning. I am duplicating it here, without the warning, and it should conflict with the other PR.

Clean up ProjectConverter3To4 architecture, move renames map to separate file This allows properly limiting what features depend on the RegEx module (doing the actual conversion) and what features only require the renames data (GDScript suggestions). Also better excludes the conversion command line options when actually disabling deprecated code. Fixes #73029.

Scripts with static variables are kept in memory indefinitely unless the `@static_unload` annotation is used or the `static_unload()` method is called on the GDScript. If the custom function `_static_init()` exists it will be called when the class is loaded, after the static variables are set.

GDScript: do not warn of return value discarded for super() inside _init() DO NOT BATCH MERGE WITH #77324, WILL RESULT IN BROKEN CI Currently, calling super() inside _init() throws a RETURN_VALUE_DISCARDED warning. The analyzer identifies super() as being a constructor, which therefore returns an object of the relevant class. However, super() isn't really a constructor by itself: in this case, it is _part_ of the constructor, and so doesn't "return" a value. A test case for this is already in #77324, which contains the warning. I am duplicating it here, without the warning, and it should conflict with the other PR.

GDScript: add errors when calling unimplemented virtual functions This PR does a small refactor of how method flags are handled in the GDScript analyzer. This way, it adds support for the analyzer to use any of MethodInfo's flags, where previously it could only use METHOD_FLAG_STATIC and METHOD_FLAG_VARARG. As a side-effect, this also normalizes behavior between editor and release templates, which fixes #76938. The tests added also brought a different issue to light, where using `super()` appears to generate a return variable discarded on calling super's _init(), which doesn't have a return value. This should be tackled in a different PR, which will have to change the output of this PR's tests.

GDScript: Check if method signature matches the parent To guarantee polymorphism, a method signature must be compatible with the parent. This checks if: 1. Return type is the same. 2. The subclass method takes at least the same amount of parameters. 3. The matching parameters have the same type. 4. If the subclass takes more parameters, all of the extra ones have a default value. 5. If the superclass has default values, so must have the subclass. There's a few test cases to ensure this holds up.

GDScript: Add warnings that are set to error by default - Adds a list of default levels for all warning so they can be set individually. - Add warnings set by default to error for: - Using `get_node()` without `@onready`. - Using `@onready` together with `@export`. - Inferring a static type with a Variant value. - Overriding a native engine method. - Adjust how annotations to ignore warnings are treated so they also apply to method parameters. - Clean up a bit how ignored warnings are set. There were two sets but only one was actually being used. - Set all warnings to the `WARN` level for tests, so they they can be properly tested. - Fix enum types in native methods signatures being set to `int`. - Fix native enums being treated as Dictionary by mistake. - Make name of native enum types use the class they are defined in, not the direct super class of the script. This ensures they are always equal even when coming from different sources. - Fix error for signature mismatch that was only showing the first default argument as having a default. Now it shows for all.
