de7d8995d5 Added string representation of 'static const' token
No more 'Unknown(-141)' in 'Expecting ...' error message

7df698dad8 - implemented the parser basics of a ZScript versioning system.
Note that this completely disables the newly added keywords 'play' and 'ui' for unversioned code to allow using them as identifiers as I have found at least one mod that uses a variable named 'play' that would have been rendered broken otherwise.
This also disables many ZScript only keywords for other parsing jobs.

b5ab011bb9 Static virtualscope checking. This is possible, because virtualscope can't produce false positives (data readable for everyone), only false negatives (which are handled at runtime later) 2017-02-18 04:07:12 +02:00

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

5e5d0d3e57 Using separate keyword 'nonew' as reverse abstract; nonew is inherited, and nonew class can only be created from the first nonew class in the hierarchy 2017-02-16 12:40:09 +02:00

03283de4e8 - fixed issues with option menu items.
- fixed the octal parser in strbin.
- remove 'new' token because it gets in the way.

6f5fff00a0 Implemented static methods in String struct. Implemented String.Format and String.AppendFormat. Implemented native vararg methods for the future. 2017-01-21 10:32:26 +01:00

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.

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

5ce5466e18 - scriptified hexenspecialdecs.
- made '->' a single token. Although ZScript does not use it, the parser tends to get confused and fatally chokes on leftover arrows so this ensures more robust error handling.

2ece9b6172 - scriptified Heretic's staff and wand. 2016-11-24 10:39:16 +01:00

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.

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.

3fa315aaea - replaced 'vector<2>' and 'vector<3>' with 'vector2' and 'vector3'.
- added initializer syntax for vectors. A vector can be set with vectorvar = (x,y,z); for a 3-dimensional vector and vectorvar = (x, y); for a 2-dimensional one.

9f8a5dae21 - scriptified A_BruisAttack.
- removed 'self' as a dedicated token. Internally this gets handled as a normal but implicitly named variable so the token just gets in the way of proper processing.
- removed P_ prefix from SpawnMissile export.
- fixed a crash with misnamed function exports.

a2116fc7bf - created an export for P_SpawnMissile so that I can do some tests with functions.
- allow class extensions.

These are separate blocks in different files that get concatenated to one class body for processing. The reason is to allow spreading the many functions in Actor over multiple files, so that they remain manageable. For example, all the Doom action functions should be in their respective files, but their symbols need to be in Actor. To extend a class, both files need to be in the same translation unit, so it won't allow user-side extension of internal classes.

665d752686 - added 'null' token to the ZScript parser which is needed for null pointers.
- removed function declaration parser from DECORATE because it is not needed anymore.
- fixed: comparison operators could not handle names.

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.

3a598d672e - removed the angle_t type from the VM, now that nothing in the interface requires it anymore. 2016-03-25 14:55:01 +01:00

964ff46063 Add new state options to parser and actually enable them
- Added new state options that DECORATE got to the lemon parser.
- Enable token generation for state options. They were previously not
  generated, so the grammar treated them as function calls instead.

326907f6ab Cleanup parsing of DECORATE intrinsics
- Split specific parsing for each intrinsic out of ParseExpression0 and
  into their own functions.
- Instead of reserving keywords for intrinsics, identify them by name
  within TK_Identifier's handling.

8e0151b4c1 Add FRandomPick
- This is RandomPick but for floats. Considering what RandomPick
  translates into in the scripting branch, I hope I don't regret not using
  type inference on RandomPick instead of creating a new keyword.

- Added register reuse to VMFunctionBuilder for FxPick's code emitter.
- Note to self: Need to reimplement IsPointerEqual and CheckClass, which
  were added to thingdef_function.cpp over the past year, as this file no
  longer exists in this branch.

33344201fa Let the scanner returned unsigned integers
- The scanner already recognized the u suffix for unsigned integers, but
  otherwise ignored it. Return it as a proper token.

081ebbb64b - I have decided to opt for simplicity over C-like-ness and group array sizes with the rest
of the type declaration rather than split it up after the variable name.
- More AST work. At this rate, maybe I'll finally be building a complete AST by the end of the
  month!
