Robbert van der Helm 58736f5cc8 Add a super unsafe channel buffer adapter 
To avoid having to perform lifetime magic here, this buffer needs to own
the slices and be stored as part of the RwLock.
 2022-02-02 13:02:28 +01:00
Robbert van der Helm 7752ce6771 Add symmetrically and asymmetrically skewed ranges 
This is super useful. I'm sure the symmetrical implementation can be
optimized a lot, but my math-fu was not strong enough today.
 2022-02-01 23:37:28 +01:00
Robbert van der Helm 4aa85b43b4 Move parameter implementation details to a module 2022-02-01 21:01:28 +01:00
Robbert van der Helm 6bb83061dd Rename the params module to param 
It's a heterogeneous module, and splitting the ranges to their own
module will be a bit weird otherwise.

Robbert van der Helm 473447179f Handle idempotent latency changes 2022-02-01 17:17:10 +01:00
Robbert van der Helm e2e2c59d34 Pass the process context to the plugin 2022-02-01 17:09:23 +01:00
Robbert van der Helm 3a1fbed4c3 Mark MainThreadExecutor::execute as unsafe 
This should only be called from the main thread. Otherwise the API's
threading guarantees will not be upheld.
 2022-02-01 17:01:05 +01:00
Robbert van der Helm 459175b470 Call the component handler for restarts 2022-02-01 16:59:11 +01:00
Robbert van der Helm 223d0c3a90 Take a reference to the component handler 2022-02-01 16:52:55 +01:00
Robbert van der Helm d47aac25a1 Rearrange WrapperInner parameters 2022-02-01 16:40:51 +01:00
Robbert van der Helm 565d9259c3 Use weak references to the executor 
So this cyclic reference can't keep it alive.
 2022-02-01 15:31:16 +01:00
Robbert van der Helm f009384c2f Don't require Arcs for ProcessContext 
It makes more sense to pass this as a reference, so the plugin cannot do
weird things with it.
 2022-01-31 23:47:54 +01:00
Robbert van der Helm 22995df7ea Actually only calculate hashes once 2022-01-31 22:42:36 +01:00
Robbert van der Helm 7c57ac6737 Fix typo in hash overflow warning 2022-01-31 22:39:11 +01:00
Robbert van der Helm 0aad790fd7 Fix deserializing boolean parameters 2022-01-31 22:32:20 +01:00
Robbert van der Helm 85db4d82df Fix param_id_to_hash name 
These were swapped for some reason.
 2022-01-31 22:24:07 +01:00
Robbert van der Helm 880ee92a47 Drop param_id_to_hash 
As it turns out, it's redundant (and also had the opposite name).
 2022-01-31 22:23:29 +01:00
Robbert van der Helm fe8f1d27d6 Use a stable ordering for the parameters 
As the fields are specified on the parameters struct.
 2022-01-31 22:20:09 +01:00
Robbert van der Helm 260d38580b Warn on parameter hash overflow 2022-01-31 21:34:36 +01:00
Robbert van der Helm 4734a51440 Move wrapper data to an inner struct 
This fixes the soundness issue with the use of Arc. Moving a `Box` to an
`Arc` frees the old boxed data, and the internal reference counting
would also try to free that. As an added benefit, we no longer need the
unsafe Send+Sync implementation for the event loop.
 2022-01-31 20:18:12 +01:00
Robbert van der Helm 6c518fad9d Add stubs for using the event loop in VST3 wrapper 2022-01-31 19:47:16 +01:00
Robbert van der Helm 4495064558 Redesign the wrapper's interiors for thread safety 
There are a lot of locks needed now here, but none of them should be
contended. This is much better than potentially having RefCell's blow up
due to simultaneous mutable borrows, and the Arc is needed for the event
loop.
 2022-01-31 19:44:02 +01:00
Robbert van der Helm 1a2c90fdfd Set the VST3 parameter step counts 2022-01-31 13:33:30 +01:00
Robbert van der Helm 6494d1ed5f Store persistent fields as plain JSON strings 
On second thought, this is much better. The resulting file size will be
much smaller because only double quotes need to be escaped. It's also
easier to read at a glance.
 2022-01-30 18:23:13 +01:00
Robbert van der Helm 3111d75b29 Serialize custom persistent fields as base64 
This still takes up more space than plain JSON would, but I don't know
if serde_json would allow inlining that JSON. Presumably not. It would
get hairy quickly as a regular embedded JSON string due to the encoding.
 2022-01-30 18:15:01 +01:00
Robbert van der Helm 29a0f83163 Add a TODO on packing stored state 2022-01-30 17:29:25 +01:00

Robbert van der Helm 16238f1e00 Support VST3 parameter flushes 2022-01-30 01:50:22 +01:00
Robbert van der Helm 6ddae6a506 Handle the output channel map 
I apparently committed this a bit too early.

Robbert van der Helm 47d102f2ba Implement restoring parameter values 2022-01-29 16:42:20 +01:00
Robbert van der Helm ebb74a737c Use plain instead of unnormalized in the APIs 
It takes more effort than what should be needed to tell normalized and
unnormalized apart at a glance.
 2022-01-29 14:54:48 +01:00
Robbert van der Helm 97a88e0db2 Implement saving parameter state 
Restoring is next.

Robbert van der Helm b9d38f5c39 Implement most of IAudioProcessor 
Except for the process function itself.
 2022-01-28 13:40:47 +01:00
Robbert van der Helm a34293fbb4 Silence too_many_arguments Clippy lint in wrapper 
Aside from wrapping everything in another struct we can't really do
anything about this since this is all generated by the VST3 macro.
 2022-01-28 13:39:44 +01:00
Robbert van der Helm 5e17b2190a Add null pointer checks to the VST3 wrapper 2022-01-27 22:51:49 +01:00
Robbert van der Helm 91e20f1230 Don't internally use param string IDs in wrapper 
This avoids a layer of indirection for every parameter lookup using a
hash.
 2022-01-27 22:36:46 +01:00
Robbert van der Helm 217b28fdca Move VST3 categories and class ID to a new trait 
Makes more sense than having this in either the general plugin trait or
as part of the macro.

Robbert van der Helm dc6db232ed Pass a CID to the VST3 export macro 
Seems much less prone to breakage than generating them, since this way
the programmer has full control.
 2022-01-26 19:20:39 +01:00
Robbert van der Helm bd2e0eca0c Add a strlcpy implementation 2022-01-26 19:18:31 +01:00

Robbert van der Helm 070e68c084 Move nih_plug to the repo's root 
Makes more sense to have this be on the same level as the workspace
since technically this crate can be used separately.
