Robbert van der Helm 0ecec104fb Completely reset smoothing on init or restore 2022-02-02 21:41:20 +01:00
Robbert van der Helm 1336139a65 Update smoothers on init and state restore 
Otherwise this would be filled with default values.
 2022-02-02 21:33:20 +01:00
Robbert van der Helm e30a72888a Add an update_smoother() parameter method 2022-02-02 21:26:34 +01:00
Robbert van der Helm ea7dc2ffa3 Implement smoothing for integers 2022-02-02 21:26:20 +01:00
Robbert van der Helm 8f89754ba5 Add simple linear parameter smoothing 2022-02-02 21:26:13 +01:00
Robbert van der Helm fced4001c0 Access plain values using the method 
Since we're also setting them using the method.
 2022-02-02 20:39:04 +01:00
Robbert van der Helm a42649b2de Derive a Default instance for the Buffer 
To make Clippy happy.
 2022-02-02 20:37:06 +01:00
Robbert van der Helm 13369e4085 Reinitialize the plugin after restoring state 
This lets you use the parameters to set fields on the plugin struct
during `initialize()`.
 2022-02-02 15:39:55 +01:00
Robbert van der Helm c982ad9599 Avoid duplicate state restores 2022-02-02 15:32:21 +01:00
Robbert van der Helm c8cc6bd26b Re-export all user facing includes 2022-02-02 15:16:10 +01:00
Robbert van der Helm f44597df7c Move the buffer adapter to its own module 2022-02-02 15:01:41 +01:00
Robbert van der Helm 048d69213e Make the buffer own the output slices 
This gets rid of a lot of lifetime casting and other unsoundness.
 2022-02-02 14:41:35 +01:00
Robbert van der Helm fbadfe3e12 Fix clippy lints 2022-02-02 13:02:28 +01:00
Robbert van der Helm 6cde9cea0e Simplify spawn_unchecked lifetime transmute 2022-02-02 13:02:28 +01:00
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 63e4a54d7c Center skewed parameters around the skew center 
It's a bit awkward and you can completely lose some parts of the range
if you don't do this.
 2022-02-02 00:06:07 +01:00
Robbert van der Helm 1202b2b9d6 Update unimplemented features list 
These things are now all implemented.
 2022-02-01 23:39:13 +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 740868a10c Move parameter ranges to their own module 
This module was too difficult to navigate with parameter types + ranges
+ implementation details.
 2022-02-01 21:06:13 +01:00
Robbert van der Helm 27bef6fbbc Move the param trait up in the module 2022-02-01 21:02:58 +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 bc60dc35b6 Fix rustdoc references 2022-02-01 20:53:20 +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.
 2022-02-01 20:51:22 +01:00
Robbert van der Helm 15e0f6f21a Remove unnecessary import 
I was going to add that set_parameter function in the next commit, but
that will need to wait a bit.
 2022-02-01 19:54:35 +01:00
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 98076ff792 Use a custom .spawn_unchecked without nightly req 
Courtesy of Yandros on the Rust Discord.
 2022-02-01 15:04:36 +01:00
Robbert van der Helm 8a0e083168 Add a TODO and stub for parameter smoothing 2022-02-01 00:14:33 +01:00
Robbert van der Helm b15991a495 Add a todo and stub for setting parameter values 2022-02-01 00:01:52 +01:00
Robbert van der Helm 735cec4fba Update context docs 2022-02-01 00:01:43 +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 5aec636f9f Format boolean parameters as On/Off by default 2022-01-31 22:36:58 +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 54bcf52912 Add Default implementations for parameter types 2022-01-31 21:19:40 +01:00
Robbert van der Helm 6fc733e029 Add callbacks for parameter changes 2022-01-31 21:02:47 +01:00
Robbert van der Helm 44172da94f Use Arcs for the callbacks 
So it becomes possible to reuse one callback for multiple parameters.
This will be important for value change notifications.
 2022-01-31 20:44:10 +01:00
Robbert van der Helm c883e0000d Move the PersistentField implementations 2022-01-31 20:41:46 +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 2380768bad Add a Linux-specific event loop 
Implementations for Windows and macOS should be fairly similar, but
using the OS' message loop instad of a thread.
 2022-01-31 19:45:11 +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 b65158283a Support parking_lot mutexes and rwlocks 2022-01-31 19:42:35 +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 64cf04a77d Add a todo about parking_lot 2022-01-30 17:10:42 +01:00
Robbert van der Helm 486fc67a4b Serialize persistent fields for VST3 plugins 2022-01-30 17:09:18 +01:00
Robbert van der Helm 221e424f78 Use thread safe interior mutability for persist 
Sadly there's not really a safe way to do this otherwise, but if you
really want to have persistence this way and absolutely need it to be
lock-free (because you're going to use it from the GUI thread), then you
can implement your own PersistentField.

Robbert van der Helm 6ddae6a506 Handle the output channel map 
I apparently committed this a bit too early.

Robbert van der Helm dabd2beca8 Add functions for interacting with plain values 2022-01-29 14:59:59 +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.
 2022-01-29 14:20:14 +01:00
Robbert van der Helm ef021915e5 Move the PlainParam functions to a trait 
We can use this for setting parameter values, as a &Param can be turned
into a pointer which can then later be mapped to a parameter ID to
handle outputting parameter values.
 2022-01-29 13:39:01 +01:00
Robbert van der Helm 5697183918 Rename from_string to set_from_string 
To make it a bit more obvious at a glance that this mutates the
parameter.

Robbert van der Helm 38bcf33a50 Use the precalculated bypass parameter hash 2022-01-28 14:52:04 +01:00
Robbert van der Helm 3064132821 Improve and simplify token handling in macros 
The standard library macros also use a `$($foo:tt)*` for this, so we
should probably too. Since eprinln!() already handles trailing commas we
don't need to do any special handling, and this fixes parsing with
complex expressions as arguments.
 2022-01-28 14:47:26 +01:00
Robbert van der Helm 71dc144c73 Add a simple formatters library 
We can add common formats here so you don't need to repeat them all the
time.

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 fa13371c5f Allow trailing commas in debug macros 2022-01-28 13:32:37 +01:00
Robbert van der Helm b91a02baa6 Add a todo and idea for non-parameter persistence 2022-01-28 01:34:36 +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.
