9e2830a3db - converted the rest of actors/shared.
- moved damagetype definitions to MAPINFO. These were in DECORATE which is not correct. The old code is left for compatibility.

905e44713f - deprecated A_SetUserVar family for ZSCRIPT due to its muddled semantics. Better use direct variable access which is a lot safer and also provides better error checking. 2016-10-14 09:32:45 +02:00

97107b6b6d Update lempar.c to 2016-10-04 version
- Every update rolled into one, because I'm pretty sure I missed some while
updating lemon.c (not counting today's commits), since it wasn't always
updated at the same time as lemon.c.
- In particular, I think this check-in from 2016-06-06 was very important to
  us after commit 3d5867d29e (For the
  Lemon-generated parser, add a new action type SHIFTREDUCE and use it to
  further compress the parser tables and improve parser performance.):
  * Fix lempar.c so that the shift-reduce optimization works for error
    processing.

696beca40f Lemon update 2016-08-16 16:46:40 on branch trunk
— Fix a bug in destructorprocessing of Lemon. That has no impact on the SQLite grammar. The bug was introduced by prior work to optimize the Lemon-generated parser used by SQLite. (user: drh)

7de683f9f5 - converted a few more DECORATE files.
- started with the AST converter. So far it only deals with direct function calls with simple constants as parameters.
- added an error condition for the defaults block to get rid of some asserts.

7e8d7eb2ec - fixed parsing of 'damage' default property.
- fixed processing of goto labels.

433bf46010 - removed token 'mode' because it isn't used anywhere and clashed with some actor properties.
- fixed uninitialized counter variable in DECORATE parser.
- allow dottable_id of xxx.color so that the property parser can parse 'powerup.color'.
- fixed crash with actor replacement in script compiler.
- add the lump number to tree nodes because parts of the property parser need that to make decisions.
- removed test stuff.
- converted inventory.txt, player.txt and specialspot.txt to ZSCRIPT. These were the minimal files required to allow actor.txt to parse successfully.
- removed the converted files from the DECORATE include list so that these are entirely handled by ZSCRIPT now.

a72fbb771f - separated the code generation from the DECORATE parser and cleaned up the interface to the code generator. Most importantly, the VMScriptFunctions are now preallocated when being added to the list of functions to compile and will be filled in later by the code generator. This allowed the removal of some ugly maintenance code. 2016-10-13 00:53:59 +02:00

59ed26c0b6 - resorted some of thingdef.cpp's contents into more appropriate files.
- split FinishActor into several functions. While DECORATE can, ZSCRIPT cannot do all this in one go.
- split the state finalization into several class-specific virtual functions.

b1a83bfd26 - started with cleanup and separation of DECORATE code.
* everything related to scripting is now placed in a subdirectory 'scripting', which itself is separated into DECORATE, ZSCRIPT, the VM and code generation.
 * a few items have been moved to different headers so that the DECORATE parser definitions can mostly be kept local. The only exception at the moment is the flags interface on which 3 source files depend.

Christoph Oelckers
6a8ab9a4d3 - implemented the state compiler. So far all it can handle is parameter-less functions.
To do the rest, some cleanup is needed first, to untangle the DECORATE parser from the actual code generation so that the low end stuff can actually be reused here instead of having to be redone.

6f92efc72c - renamed thingdef_codeptr.cpp and moved it out of thingdef/.
Ultimately, thingdef should only contain code that is directly related to the DECORATE parser, but that's not the case with this file. It's only function definitions which get used during gameplay and will also be accessed by ZScript.
The change is intentionally on master so that pull requests can adjust to it now instead of creating conflicts later.

f46b6b5be5 - fixed some issues with the grammar for parsing states:
* Goto did not support the class scope operator '::'. Like in DECORATE, this cannot be done with a simple '.' because it creates semantic problems with first part of a state label. This requires different syntax so that it can unambiguously distinguish between a scope identifier and the actual label
 * Goto used the incorrect token PLUS for '+' instead of ADD.
 * The state's duration was not stored in the AST.
 * Truncating the sprite name inside the parser is probably not the best idea because it used a simple Printf to report this. Let's do this during processing of the AST where this can be properly handled as an error.

5dc94a10c3 Added A_SetInventory.
- Sets the absolute amount of an inventory actor.
- Limits itself to the range [0, MaxAmount]. Setting beyondMax to true disregards the MaxAmount. Default is false.

d8c689d874 - initialize function symbols. At the moment all it does is process the existing native functions. Any further processing will be done once the base classes of the engine can be parsed from the scripting files.
- switched the types of the internal 'self' and 'stateowner' parameters so that they get assigned correctly. I can't tell if this will error out if fields get accessed from the caller with the wrong class, but for actual scripting to work these must be correct.

The committed 'actor.txt' can be parsed successfully, with the exception of a few subclass references that cannot be resolved yet.

bdbc7c3fb7 - removed CreateDamageFunction, because it's no longer needed for defining a 'damage' constant. 2016-10-11 14:43:17 +02:00
Christoph Oelckers
6989b81688 - extended the grammar so that the DECORATE function declaration list can almost be used as-is, with the sole exception of requiring any action function to declare a return type, even if it is void.
This adds:
 * builtin types color, state and sound.
 * ending a parameter list with an ellipsis to declare a varargs list. (A_Jump uses this.)
 * allowing to declare optional arguments by giving them a default value.
 * adding an 'action' qualifier for function declarations.

Christoph Oelckers
3b19887637 - implemented the Defaults property initializer.
This uses the same property and flag tables as DECORATE with a few changes:

 * it sets the parse mode to strict, so that several DECORATE warnings are now errors.
 * trying to change a deprecated flag will print a warning.
 * setting of editor numbers, spawn and conversation ID id not possible. Use MAPINFO to do this.
 * all subclass flags must use the qualified name now (e.g. +ALWAYSPICKUP will print an error.)
 * the scriptable Damage property is not yet implemented. This will require a special case with a differently named property in the processing function because in the AST it is no longer possible to distinguish between a damage value and a constant damage function.

084bf8c576 - fixed: VisibleAngle and VisiblePitch actor properties require both parameters to be present, but the second one was set to optional. 2016-10-11 00:23:50 +02:00
Christoph Oelckers
2b9af0176c - changed grammar for a class's default block to look and act like DECORATE, so that it can hook into the same property dispatcher.
This had been defined as a regular compound statement but in the context this will be used in, that makes very little sense, because all it can do is set some constant values.
The most important thing here is that it doesn't provide an unnecessary learning curve to its users and doing it this way will not only ensure that but also avoid redundant documentation.
To allow initialization of other user-defined properties it will require some extensions but that's a job for later and can just as easily be done in the current framework, rather than throwing everything out and start from zero.

31ca5a1900 Added OverlayX/Y(int layer)
- Retrieves the X/Y positions of an overlay.
- A_OverlayFlags and A_OverlayOffset now interpret a layer of 0 to mean 'use this calling layer'.

e84d6a06d8 - changed PClass:AddField so that it doesn't create defaults if none are present. The ZScript compiler will not create any defaults until after all fields have been added and this function created bad data if it was run on a class without defaults.
- added checks for duplicate field names.
- moved the tree node symbol tables out of PSymbolTreeNode to the worker data. That symbol is a bad location because it restricts the usefulness of the symbol class which is also needed for variables which use different AST structs.
- fixed some memory management issues with the work classes for the compiler that became apparent after moving the symbol tables in there. In several places these were copied around, possibly losing data.

ad43f2bc7e - parse the list of class/struct fields and add the PField entries to their type.
- fixed a few issues with trying to access a class's Type before it got initialized.

49f18c0a19 - renamed the symbol tables holding the tree nodes so that the code becomes clearer to read. Necessary because the unclear naming caused:
- fixed: The tree nodes for classes and struct members were stored in the global tree nodes table.
- sort variable declarations into their own list for processing.

08f313d011 - implemented complete resolving of constants - both global and class-local.
This uses a different algorithm as the old implementation - instead of recursively resolving unknown symbols it will first collect all constants from all scopes and then process them in one operation, doing multiple passes over the list until no more constants can be resolved anymore.

5bb6bb31ca - added ProcessStruct, analogous to ProcessClass.

d139ee9f68 - give the 'default' block its own node type in the AST.
- group a class's body the same way as the global AST. Only partially implemented so far so that constants can be processed.

82ac2081b6 - create struct types.
- fixed class creation. There was an infinite loop and some missing checks for native classes.
- do not write the compiler's symbols to the same symbol table as the output. The output must go to GlobalSymbols but the internal symbols must go to a namespace specific table that can be discarded after compilation.

b71e8d09ed - create class types from the AST.
This is the first thing the compiler has to do to get access to the class's symbol table. Of course at this point the final size of a class is not known yet so these are currently all treated as tentative.

994bb4fc7a - started to make ZScript parser work on real-life data. It will now read a lump named ZSCRIPT which is a list of filenames to be compiled.
- place generated symbols into GlobalSymbols instead of a scratch table that will be discarded right away.
- allow the state object to change source file scanners (I hope this works, but the old implementation was unable to do more than one with with a parse state so I had to change it.)
- It can now parse constants.txt and insert everything in it into the global symbol table and make subsequent DECORATE compile properly.

d819aafcf3 - changed handling of duplicate classes in DECORATE.
Instead of replacing the original, the second class will get renamed now, using the originating file as an identifier. In the vast majority of cases this should do exactly what is needed: Create an unconflicting second class that can coexist with the original. Unless the class is used by name this should eliminate all problems with this, but so far I haven't seen anything that used them by name.

This is choosing the lesser of two evils. While some mod out there may get broken, the old setup meant that the first class of a given name could not be written out to a savegame because it was not retrievable when loading it back.

06ca41f8b5 - do not declare PNamedType::Outer as DObject.
Ultimately we may have to get a fully qualified name out of this, so Outer should be a type that can handle this feature. The new class for this is currently used as base for PType and PSymbol so that PNamedType inherits from it and maybe later a namespace symbol can, too.
