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.

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.

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.

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.

Robbert van der Helm 2f59adadcc Update vst3-sys to a version with atomic refcounts 2022-01-31 19:42:35 +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.

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 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.

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 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
