0f031c5f22 Renamed 'allowui' to 'clearscope'. 'allowui' doesn't reflect the real meaning of the keyword which clears implicit 'play' or 'ui' inherited from parent class (for classes) or owning type (for methods/fields) 2017-02-17 18:24:01 +02:00

Christoph Oelckers
776509e68a - let skip_super use the AActor assignment operator. The blanket memcpy it used was clobbering some data.
- moved the Finalize method from PClassActor to AActor. Now that defaults get their vtbl pointer initialized this will actually work.

ca48a687f8 - major work on dynamic array support. Mostly working, some issues still exist with Move and Copy methods and with assignments in stack variables. 2017-02-06 21:39:21 +01:00

6d28aa3541 - do not use strtol for parsing critical values that can get large.
This function will truncate everything that is larger than LONG_MAX or smaller than LONG_MIN to fit into a long variable, but longs are 32 bit on Windows and 64 bit elsewhere, so to ensure consistency and the ability to parse larger values better use strtoll which does not truncate 32 bit values.

eef91463ab - fixed: Non-actor classes never called InitializeDefaults to set up their special variables.
- fixed: DThinkerIterator and DBlockThingsIterator did not have a default constructor that was safe to call from an out-of-game context.

3f999a990c - removed a line of debug code that made GCC/Clang go nuclear. 2017-01-23 23:06:29 +01:00
Christoph Oelckers
b3aa7c61a9 - fixed: Class and struct name lookup was not context aware.
If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files.
Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed.

Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values.

Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class.

Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore.

- made PEnum inherit from PInt and not from PNamedType.

The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

5a4a5a17db - added core lump checks for ZScript.
- load internal shaders only from file 0. This does not contain aborts, like most of the other checks,but it will now refuse to load any core shader file from anything but gzdoom.pk3.

3c30b59bab more inventory scriptification
* completely scriptified DehackedPickup and FakeInventory.
* scriptified all remaining virtual functions of Inventory, so that its inheritance is now 100% script-side.
* scriptified CallTryPickup and most of the code called by that.

- fixed: Passing local variables by reference did not work in the VM.

Christoph Oelckers
98f9219334 - scriptified the remaining functions in a_artifacts.cpp.
- added some helpers to set scripted member variables through the native property parser.

Unfortunately some classes, e.g. PowerMorph, MorphProjectile and the powerup contain some that cannot be handled through the 'property' definition on the script side so they need to be done from the native side.

Christoph Oelckers
179b6e1a39 - added property definitions to the ZScript parser. This will allow defining custom properties for the default block in custom base classes. See 'Health' for an example.
- support transient object member variables for information that does not need to be put in a savegame.
- fixed: special initialization of objects needs to pass the proper defaults along, otherwise the parent classes will use their own, inappropriate one.

de4153ceaf some groundwork for the implementation of dynamic arrays
- created script exports for all relevant functions with all integral types.
- created script side definitions for the underlying data types.
- added a void pointer type so that the prototype for the pointer array can use a generic type every pointer can be assigned to.

8036719f45 - Add GCCPRINTF to ZScript compiler code.

Christoph Oelckers
902a4b839c - fixed: Type determination of multi-dimensional arrays failed, apparently because ZCCCompiler::Simplify is too broken to leave the node's ring list intact.
Instead of trying to fix Simplify, which seems to be a lost cause, the ring list now gets unraveled into an array which is immune from this type of problem.

52645afb4b - for the time being, make ZScript command line switch locked so that everybody understands that it's not ready for use in released mods yet. 2016-12-06 22:42:10 +01:00
Christoph Oelckers
f722967abe - added automatic type deduction capabilities for local variables. If you type 'let variable = value;' the type of 'variable' will be deduced from the given value. This is mostly of interest for type casting pointers, because 'let p = Classtype(objectvar);' does not require writing the class type name twice. 2016-12-05 13:24:42 +01:00

71bda99c3b - fixed: DECORATE didn't pass all needed arguments to FunctionBuildList.AddFunction. Removed the default parameter values from this function's declaration to prevent it from happening again. 2016-12-03 18:14:07 +01:00
Christoph Oelckers
0da233a664 changed ZScript include mechanism.
* It will now use #include, just like most other definition formats and can be mixed with regular definitions. However, due to how the Lemon-generated parser works this will not recursively pull in all files, but store them in a list and process them sequentially. Functionally this shouldn't make a difference, because ZScript is mostly order-independent - the only thing where order is important is native classes, but these are completely internal to zdoom.pk3 where proper order is observed.

Christoph Oelckers
86544086df - allow the VM to run on one global stack per thread.
It is utterly pointless to require every function that wants to make a VM call to allocate a new stack first. The allocation overhead doubles the time to set up the call.
With one stack, previously allocated memory can be reused. The only important thing is, if this ever gets used in a multithreaded environment to have the stack being declared as thread_local, although for ZDoom this is of no consequence.

- eliminated all cases where native code was calling other native code through the VM interface. After scriptifying the game code, only 5 places were left which were quickly eliminated. This was mostly to ensure that the native VM function parameters do not need to be propagated further than absolutely necessary.

3af9232fca - scriptified a_strifeitems.cpp and a_debris.cpp.
- Changed the glass shards so that they do not have to override FloorBounceMissile. It was the only place where this was virtually overridden and provided little usefulness.
- made 'out' variables work.
- fixed virtual call handling for HandlePickup.

8551a4f6e1 - scriptified the Sigil. This isn't fully tested yet. 2016-11-28 14:39:25 +01:00
Christoph Oelckers
de6969997a - scriptified Hexen's flies.
A few notes:

 * this accesses the lines array in sector_t which effectively is a pointer to an array of pointers - a type the parser can not represent. The compiler has no problems with it, so for now it is defined internally.
 * array sizes were limited to 65536 entries because the 'bound' instruction only existed as an immediate version with no provisions for larger values. For the static map arrays 65536 is not sufficient so now there are alternative instructions for these cases.
 * despite the above, at the moment there is no proper bounds checking for arrays that have no fixed size. To do this, a lot more work is needed. The type system as-is is not prepared for such a scenario.

aab304c0cf - fixed: Lemon includes ParseTrace only in debug builds so the option to use it must be #ifdef'd. 2016-11-27 17:43:11 +01:00
Christoph Oelckers
36f559ecb7 - fixed bad definition of struct grammar which tried to resolve from right to left, creating large amounts of recursion and strange problems with PlayerInfo.
- added a command line option to generate a parser trace file.

Christoph Oelckers
177aa6ec42 - converted half of ClericHoly. (Making a commit before starting on the more complex stuff.)
- added a 'constructor' for color values.
2016-11-26 13:18:48 +01:00
Christoph Oelckers
66d28a24b8 - disabled the scripted virtual function module after finding out that it only works if each single class that may serve as a parent for scripting is explicitly declared.
Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going.
It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

Christoph Oelckers
9ae272d753 - scriptified Heretic's blaster.
- scriptified all Effect functions of Fastprojectile's children
- implemented access to class meta data.
- added a VM instruction to retrieve the class metadata, to eliminate the overhead of the function call that would otherwise be needed.
- made GetClass() a builtin so that it can use the new instruction

Important note about this commit: Scriptifying CFlameMissile::Effect revealed a problem with the virtual function interface: In order to work, this needs to be explicitly enabled for each single native class that may be used as a base for a scripted class. Needless to say, this will end up way too much work, as there are over 100 native classes, excluding those which will be scriptified. But in order to fix the problem this partially broken state needs to be committed first.

cd919e72e1 - Don't null-check the ZCC_TreeNode 'this' pointer.
Compilers are allowed to simplify the 'this == nullptr' code block because it makes no sense in 'well-defined C++ code'.

5e67cf79d3 - scriptified the Ironlich. 2016-11-23 21:26:59 +01:00
Christoph Oelckers
099b9970ef - added proper definitions for all exported native fields.
- synthesize native fields for all declared flags, not just for AActor.
2016-11-22 23:43:32 +01:00
Christoph Oelckers
980c986305 - allow defining native fields through scripts. Internally this only requires exporting the address, but not the entire field.
- added new VARF_Transient flag so that the decision whether to serialize a field does not depend solely on its native status. It may actually make a lot of sense to use the auto-serializer for native fields, too, as this would eliminate a lot of maintenance code.
- defined (u)int8/16 as aliases to the byte and short types (Can't we not just get rid of this naming convention already...?)
- exporting the fields of Actor revealed a few name clashes between them and some global types, so Actor.Sector was renamed to CurSector and Actor.Inventory was renamed to Actor.Inv.
2016-11-22 19:20:31 +01:00
Christoph Oelckers
135cfcf016 - implemented State as an actual native struct, so that its fields can be accessed from scripts.
- refactored state bitfield members into a flag word because the address of a bitfield cannot be taken, making such variables inaccessible to scripts.
- actually use PNativeStruct for representing native structs defined in a script.
2016-11-21 21:34:34 +01:00
Christoph Oelckers
6cc00e79a6 - made all internal struct types NativeStructs so that all variables of their types are made references. 2016-11-21 19:20:27 +01:00
Christoph Oelckers
360436c201 - scriptified the scripted marines.
- fixed symbol name generation for native functions.
- moved PrintableName to VMFunction so that native functions also have this information.
2016-11-21 19:09:58 +01:00
Christoph Oelckers
7d99552903 - added two new integral types SpriteID and TextureID, both are needed to allow proper serialization as they require something different to be written out than a regular integer. 2016-11-21 13:45:33 +01:00
Christoph Oelckers
de2eb18727 - added per-channel access for color variables. However, since they are locally stored in registers, it required a minor bit of fudging for this case.
- make sure that a PFunction's implementation is always initialized before starting the code generator.
2016-11-21 12:38:39 +01:00
Christoph Oelckers
e7f6bae83e - implemented named arguments.
- fixed flag CVAR access. As it turned out, OP_LBIT is a bit messy to set up properly when accessing integers that may or may not be big endian, so it now uses a shift and bit masking to do its work.
- used the SpawnPlayerMissile call in A_FireBFG to test named arguments.
2016-11-21 01:32:01 +01:00
Christoph Oelckers
5951a9449c - added static constant arrays. At the moment they can only be defined inside functions due to lack of dedicated storage inside classes for static data.
- added new VM instructions to access the constant tables with a variable index.
- refactored VMFunctionBuilder's constant tables so that they are not limited to one entry per value. While this works fine for single values, it makes it impossible to store constant arrays in here.
2016-11-20 18:00:37 +01:00
Christoph Oelckers
af34d82888 - scriptified A_Saw.
- implemented multiple-return-value assignment. Due to some grammar conflicts the originally intended Lua-inspired syntax of 'a, b = Function()' could not be done, so it's '[a, b] = Function()'
2016-11-20 00:25:38 +01:00
Christoph Oelckers
f11f020b6c - allow functions in structs. This is needed for several internal data types like players, sectors, lines, etc.
- added a new type 'NativeStruct'. This will be used for types that cannot be instantiated, and is also needed to cleanly handle many internal types that only can exist as reference.
2016-11-19 12:12:29 +01:00
Christoph Oelckers
3ce699bf9b - implemented pass-by-reference arguments - so far only for memory based variables.
- changed Dehacked weapon function lookup to check the symbol table instead of directly referencing the VM functions. Once scriptified these pointers will no longer be available.
- removed all special ATAGs from the VM. While well intentioned any pointer tagged with them is basically unusable because it'd trigger asserts all over the place.
- scriptified A_Punch for testing pass-by-reference parameters and stack variables.
2016-11-19 01:23:56 +01:00
Christoph Oelckers
34c949f84b - implemented the string concatenation operator '..'. This is capable of stringifying all of the common types for output.
- gave OP_CONCAT some sane semantics. The way this was defined, by specifying the source operands as a range of registers instead of a pair like everything else made it completely useless for the task at hand.
- changed formatting for floats to %.5f which for normal output in a game makes more sense. For special cases there should be a special formatting function for ints and floats that can do more specialized conversions.
2016-11-18 17:44:25 +01:00
Christoph Oelckers
f71aad4cdd - cleanup of the remaining FxBinary operators.
- changed FxCompareEq with strings and other types that can be cast to from a string always convert the string to the other type before comparing.
2016-11-18 14:19:55 +01:00
Christoph Oelckers
3bcd85eb8a added class pointer casts. Due to grammar problems the type has to be put into parentheses to get the class token out of the global parsing namespace:
class<Actor> myclass = (class<Actor>)(GetClass());
2016-11-17 20:31:53 +01:00
Christoph Oelckers
2cc48ec378 - implemented code generation for stack variables.
- fixed code generation for using local variables as array index. This must use a different register for the array element offset because the original register may not be overwritten.
2016-11-17 16:44:41 +01:00
Christoph Oelckers
633da6e5d8 - scriptified two of the Acolyte's functions.
- added a DActorIterator class.
- fixed: It was not possible to have functions of the same name in two different classes because the name they were searched for was not qualified by the class. Changed so that the class name is included now, but to avoid renaming several hundreds of functions all at once, if the search fails, it will repeat with 'Actor' as class name.

This commit contains preparations for scriptifying Hexen's Dragon, but that doesn't work yet so it's not included.

96d093d01f - added compile time checks for bad state links and state label references.
- preserve a state's source line information for the postprocessing phase so that the checker can output more useful information.
- added missing check for weapon psprites to DPSprite::SetState.

4f998fa879 - finished the state usage parser.
- added state usage specifiers to Actor and Inventory. The states in these classes must be set to full access so that any existing mod can link to them.

ac86a535e7 - fixed: State labels were resolved in the calling function's context instead of the called function one's.
This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx.
This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem.
Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table.
The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions.

- refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function. It is strongly recommended to use the boolean checkers unless using an inline function invocation in a state as they lead to vastly clearer code and offer more flexibility.

- let Min() and Max() use the OP_MIN and OP_MAX opcodes. Although these were present, these function were implemented using some grossly inefficient branching tests.
- the DECORATE 'state' cast kludge will now actually call ResolveState because a state label is not a state and needs conversion.

a2f4cd7cda - fixed: All functions that are callable from weapon states and not members of Actor need to be declared 'action'.
With the stricter type checks of the self pointer that were now implemented these all produced errors.

a603af805c - fixed identifier resolution in FxIdentifier for action functions with a different invoker than self.
- fixed creation of direct function invocations on a state line. In order to receive the implicit arguments this needs to be wrapped into a compound statement so that the local variable getter works.

479b216c06 - fixed: ZScript did not properly fill in tentatively created classes from defaults processing.
The proper setup for such classes was only done in CreateDerivedClass, but not in FindClassTentative itself. This extends CreateDerivedClass to allow it to create a class without fully initializing it.

72e77a6c65 - implemented handling for virtual function.
Syntax-wise I chose to make it as strict as possible to reduce the chance of errors: Virtual base functions must be declared with the 'virtual' keyword, and overrides in child classes with the 'override' keyword. This way any mismatch in parameters that otherwise would cause silent failure will outright produce a compile error.
