Tyler Wilding 18903f0561 decomp: Copy over new docstrings back to jak 2's common code, write some scripts to help automate this (#3366) 2024-02-04 13:53:06 -05:00
ManDude cd68cb671e deftype and defmethod syntax major changes (#3094)
Major change to how `deftype` shows up in our code:
- the decompiler will no longer emit the `offset-assert`,
`method-count-assert`, `size-assert` and `flag-assert` parameters. There
are extremely few cases where having this in the decompiled code is
helpful, as the types there come from `all-types` which already has
those parameters. This also doesn't break type consistency because:
  - the asserts aren't compared.
- the first step of the test uses `all-types`, which has the asserts,
which will throw an error if they're bad.
- the decompiler won't emit the `heap-base` parameter unless necessary
now.
- the decompiler will try its hardest to turn a fixed-offset field into
an `overlay-at` field. It falls back to the old offset if all else
fails.
- `overlay-at` now supports field "dereferencing" to specify the offset
that's within a field that's a structure, e.g.:
```lisp
(deftype foobar (structure)
  ((vec    vector  :inline)
   (flags  int32   :overlay-at (-> vec w))
   )
  )
```
in this structure, the offset of `flags` will be 12 because that is the
final offset of `vec`'s `w` field within this structure.
- **removed ID from all method declarations.** IDs are only ever
automatically assigned now. Fixes #3068.
- added an `:overlay` parameter to method declarations, in order to
declare a new method that goes on top of a previously-defined method.
Syntax is `:overlay <method-name>`. Please do not ever use this.
- added `state-methods` list parameter. This lets you quickly specify a
list of states to be put in the method table. Same syntax as the
`states` list parameter. The decompiler will try to put as many states
in this as it can without messing with the method ID order.

Also changes `defmethod` to make the first type definition (before the
arguments) optional. The type can now be inferred from the first
argument. Fixes #3093.

Hat Kid fc43870d85 decompiler: obj -> this, set-time! and time-elapsed? macros (#3026)
This renames the method object in `defmethod`s to `this` and adds
detection for the `set-time!` and `time-elapsed?` macros.

Definitely my biggest PR yet...

ManDude ff924f6b00 improve decomp of state handlers and art groups (#3014)
- state handlers that are not inlined lambdas have smarter type
checking, getting rid of 99.9% of the casts emitted (they were not
useful)
- art groups were not being properly linked to their "master" groups.
- `max` in `ja` in Jak 2 was not being detected.

Another huge PR...

ManDude fe491c2b5e [opengoal] make none a child of object (#3001)
Previously, `object` and `none` were both top-level types. This made
decompilation rather messy as they have no LCA and resulted in a lot of
variables coming out as type `none` which is very very wrong and
additionally there were plenty of casts to `object`. This changes it so
`none` becomes a child of `object` (it is still represented by
`NullType` which remains unusable in compilation).

This change makes `object` the sole top-level type, and the type that
can represent *any* GOAL object. I believe this matches the original
GOAL built-in type structure. A function that has a return type of
`object` can now return an integer or a `none` at the same time.
However, keep in mind that the return value of `(none)` is still
undefined, just as before. This also makes a cast to `object`
meaningless in 90% of the situations it showed up in (as every single
thing is already an `object`) and the decompiler will no longer emit
them. Casts to `none` are also reduced. Yay!

Additionally, state handlers also don't get the final `(none)` printed
out anymore. The return type of a state handler is completely
meaningless outside the event handler (which is return type `object`
anyway) so there are no limitations on what the last form needs to be. I
did this instead of making them return `object` to trick the decompiler
into not trying to output a variable to be used as a return value
(internally, in the decompiler they still have return type `none`, but
they have `object` elsewhere).

Fixes #1703 
Fixes #830 
Fixes #928

ManDude b50b9eadb2 [decompiler] new features + fixes, + other jak2 fixes (#2796)
Fixes empty boxed arrays of strings breaking some decomp
(`ctywide-speech` and `race-info`).

Adds `decomp-as` tag to decompiler types so that the static data
decompiler can use macros like `meters` and `seconds` on fields that
aren't of type `meters` or `time-frame`.

Adds `override` tag to decompiler types which overrides the type of
field with that name. The type must be a child type of the original
field's type (or the same type, but why would you do this?).

Fixes the camera being offset for `drillmtn` after loading `palout`
once.

This is a huge refactor sadly.

Tyler Wilding d13155bfd0 d/jak2: Decompile palace-ocean, ctysluma-part, nav-enemy-h and a bunch of work on enemy and nav-mesh related files (#1984)
Couldn't finish any of the enemy/nav-enemy related files for one reason
or another, but quite a bit of work that will be easier to merge and
iterate on instead of keeping track of the branch.

enemy/idle-control has some very weird focus related code.

nav-mesh/nav-control still has a bunch of CFG resolution problems that
need to be manually resolved.
