Mike Welsh b181debff6 swf: Use bitflags for `avm1::GetUrl2` 2022-01-17 21:35:57 -08:00
Mike Welsh 4c3e14eae5 core: Clean up `DefineFunction` action 
* Have `DefineFunction` and `DefineFunction2` go through the same
   code path by implementing `From<DefineFunction>` for
   `DefineFunction2`.
 * Change `register` to a `Option<NonZeroU8>` for size optimization.
 * Add `function::Param` to store param info instead of a tuple.
 2022-01-17 21:35:57 -08:00
Mike Welsh 2b2346b65e swf: Add `avm1::Action::End` 
Returning an `Action::End` instead of `None` when reading the end
of an action.

Mike Welsh d5862809c7 swf: Remove extraneous ? in avm1::Writer 2022-01-17 21:35:57 -08:00
Mike Welsh 265bcc278a swf: Add avm1::Writer::write_small_action 
Convenience method for writing zero-length actions.
 2022-01-17 21:35:57 -08:00
Mike Welsh 9141451ca1 swf: Use structs for avm1 `Action` variants 
Use a struct for all variants of `avm1::Action`.
This makes the style more consistent instead of using a mix of
struct and tuple variants, and allows the data to be easily passed
around.

relrelb 34d1fa5226 avm1: Introduce `TextFormatObject` 
`TextFormat` objects differ from regular objects in that
`TextField.setTextFormat` and `TextField.setNewTextFormat` accept
only the former, and ignore the latter.

Also, `TextFormat.prototype` has native accessors that coerce the
values on get/set.

relrelb 281455be6d swf: Improve `ActionTry` read/write 
* Use `TryFlags` instead of hard-coded binary literals.
* Rename `try_length`, `catch_length`, `finally_length` to `try_size`,
`catch_size`, `finally_size` to match SWF19 namings.
* Refactor write and fix a few bugs there:
    * The actions length should not include the try, catch, finally
    bodies, only the metadata of `flags`, `try_size`, `catch_size`,
    `finally_size` and catch variable (either as `u8` or `SwfStr`).
    * A placeholder byte should be written in place of the catch variable
    when there is no catch clause.

relrelb d49ea10267 swf: Rename `TryBlock` fields

This aligns with the names used in SWF19, and is more consistent.

relrelb 55ffda9c97 swf: Take advantage of `ClipEventFlag` bit pattern 
Re-number the `ClipEventFlag` enum members to match how they
actually appear in a SWF. This allows much simpler read/write
operations.

Also, gracefully handle malformed ClipActions that are only 1 or 0
bytes, as it seems that Flash accepts those too.

relrelb 5dde3ecabf swf: Optimize `read_f64_me` and `write_f64_me` 
Each function is reduced to just 3 opcodes on x86:
https://godbolt.org/z/n6q6zxnh6

WebAssembly benefits as well: https://godbolt.org/z/fcETE9GYn

This should improve load-time performance because read_f64_me is
used frequently (for each AVM1 double constant).

relrelb c2378416a9 tests: Simplify `read_tag_bytes_from_file_with_index` 
Let the `Reader` outlive outside the loop, so it tracks its own
position, instead of doing so manually.
Also move `read_from_file` outside and reuse it.

relrelb 99deb90a1f swf: Avoid using `Reader::input` directly 
Change two cases to use `Reader::read_slice` instead of `self.input`.
Not only this avoids relying on an implementation detail, this also
