afd9347087 - changed order of script files to match the old DECORATE list for easy comparison of the disassembly.
- added a descriptive name to all types for error messages.
- added a generic type cast node to the code generator.
- added a few more cast operations to the 'cast' VM instruction.
- extended FxClassTypeCast to handle all possible input that can be cast to a class pointer, not just names.

59ab8b7ccd - implemented array-style syntax for Random calls.
- implemented handling of the basic math operators so that heretic/beast.txt can be processed.

This is working, aside from still needing the type casts to properly transform the strings to class pointers.

d6ce60f63a - added named RNG support to FxFunctionCall.
This looks simpler than duplicating all that stuff and avoids a lot code duplication.

55f6661c87 - added handling for all the builtins supported by DECORATE to FxFunctionCall.
For the random functions this class only handles the default-RNG version. The one with an explicit RNG needs to be done separately because the parser produces different output for them.

b299b64e47 - the compile context now knows if it is invoked by ZScript or DECORATE, so that it can be more strict with ZScript if needed.
- added a truncation warning to FxIntCast, which only occurs with ZScript, not with DECORATE. FxBoolCast is intentionally left out because it would defeat the reason for this cast type.

c3e693b507 - added FindClassMemberFunction which retrieves a function symbol and performs some verification.
- removed Self parameter from FxFunctionCall. Actual member function calls through an object require quite different handling so lumping these two together makes no sense.
- added a workaround to deal with ACS_NamedExecuteWithResult to both the compiler and FindClassMemberFunction. The way the ZScript compiler sets this up means that it will call the builtin, not the actual action function, so the parser needs to do some explicit check to get past the same-named action function.
- pass a proper self pointer to FxActionSpecial. Although it's still not being used, propagating design shortcuts through several function levels is a very, very bad idea.

cbb990a79e - pass the current function to the compile context instead of just the containing class. 2016-10-15 17:40:27 +02:00

db8ab1bc4a - give PFunction a bit more information:
* explicitly require passing the owning class when creating it.
 * extract self pointer class when adding a variant.
 * put the flags on the single variants, we can not fully rule out that they will be 100% identical, if variants ever get allowed.

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.

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
Renamed from src/scripting/codegeneration/thingdef_expression.cpp (Browse further)
