32a3f57a54 - more preparations to compile functions:
* Allow PFunction to work without a VMFunction being attached.
 * The Variant for a function must store the prototype itself instead of relying on the VMFunction it points to. Otherwise it would not be possible to reference a prototype during compilation of the function because it does not exist yet.
 * Give the variant a list of the function's argument's names, because these are also needed to compile the function.
 * create an anonymous function symbol when the function gets registered to the builder. At this point we have all the needed information to set it up correctly, but later this is no longer the case. This is the most convenient info to have here because it contains everything that's needed to compile the function in the proper context, so it has to be present when starting compilation.
 * added some preparations to implement special handling for weapons and custom inventory items, which can run action functions in another actor's context. This part is not active yet but the basics are present in SetImplicitArgs.

2cb5839c11 - count errors in the parser and abort afterward if there were some.
- use FScriptPosition's error counter throughout the compiler so that there is only one counter for everything, not two.

Parts of the compiler use FScriptPosition, so this is easier to handle than having a separate counter in the compiler class. It also avoids having to pass the compiler object to any function where an error may be output. The TreeNodes contain sufficient data to be converted to an FScriptPosition and using that for error message formatting.

f86e64e712 - renamed thingdef_expression to codegen. Eventually this needs to be split up into smaller units because the file is already quite large and there's still a lot to add here. 2016-10-15 10:39:58 +02:00

d8a8b59006 - cleaned up the loop statement nodes in the code generator, which put some handling in FCompileContext and some of their data into the base FxExpression class instead of having an intermediate base class for all loops which is responsible for the relevant data. All this is now encapsulated in a new FxLoopStatement class which serves as base for the actual loop statements. 2016-10-15 10:34:26 +02:00

f23e5d2677 Fixed: XLAT would not parse
- Disable the changes from commit 96afce241d
  because it appears to not recognize default rules that reduce as
  reducing.
- When tracing a parser, flush after every line output in case an
  assert is hit so you can actually see what it did up to that point.

d00e93bdab - fixed order of state setup.
It looks like the setup of the action function and the adding of the states got inverted by something I tried, leaving the ActionFunc member empty on the real states.

52005214c1 - Added some fudging so that A_PlayerSkinCheck creates proper code until I can rewrite the FunctionCall expression to match what the script compiler needs. The current version of this class is too much geared toward DECORATE. 2016-10-14 21:15:46 +02:00

784f7ed671 - converted all of Doom's actors.
- fixed a few problems that were encountered during conversion:
 * action specials as action functions were not recognized by the parser.
 * Player.StartItem could not be parsed.
 * disabled the naming hack for PowerupType. ZScript, unlike DECORATE will never prepend 'Power' to the power's name, it always needs to specified by its full name.
 * states and defaults were not checked for empty bodies.
 * the scope qualifier for goto labels was not properly converted to a string, because it is an ENamedName, not an FName.

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.

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.

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.

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
Christoph Oelckers
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.
2016-10-12 20:42:41 +02:00
Christoph Oelckers
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.

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.

3de83b8943 Added PSPF_FLIP.
Flips the overlay on the X axis.

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.
