Now that `run_action()` returns a `Result`
(e4c21b11069297d289f25834cfc3c001a4604b5f), we need to use that `Result`
when we call it in `run_key_action()`.
Pass on the `Result` to `ffi::run_key_action()`, and print the error
message from there.
|
|
Instead of handling the error in this function, pass it up to the
caller. This will allow the error message to be printed, as we've only
allowed 'stderrlog' to print log messages in the `ffi` module.
|
|
Remove code that was commented in
44f6a2d5544e3ad49e5e3c52167c045aed1d56b2. Since we weren't able to
correctly link to the Core Audio framework from the Objective-C code
using this Rust audio code, get rid of it. Instead, we play audio in the
Objective-C application.
|
|
Take a function pointer argument that will be called whenever a mode is
activated or deactivated. We'll be using this on the Objective-C side to
play audio when the mode changes.

I was getting the following error when building the Objective-C project
with the latest audio playing code:

Couldn't figure out how to get past this, so decided to move the audio
playing into the Objective-C code. It's been something of a theme, where
if something doesn't work in one language (like
dome_key_event_source_simulator), write it in the other.
Here we just comment out the audio-related code so I can work on
connecting mode activation and deactivation and audio playing. I'll be
completely removing this code soon.

Log errors to stderr logger.
|
|
Mirror the `map::run_key_action()` function and add an extra `PlayAudio`
argument, which will control whether audio cues are played when a mode
is activated or deactivated.
The Objective-C code will pass in this value based on the value of a
`Config` setting, which will have come from a command line argument.
|
|
This has already been handled. See the condition just below the comment.
|
|
Play audio on mode activation and deactivation depending on the value of
the new argument.
Decided to make it an enum instead of a bool for better readability.
Will need to get rid of the `unwrap`s.
|
|
Now that this function no longer takes a "current mode" argument, the
"mode" part of the name doesn't make sense.
|
|
Create a new function that encapsulates the code we experimented with
for playing audio.
Clean up what we had and handle errors by passing them back in a
`Result`.
This allows us to encapsulate, audio playing so we can do it in a single
action during mode switching.
|
|
Success! Using the 'rodio' crate to play an audio file. Include the
audio file in the binary using `include_bytes!`. This makes it so we get
a single self-contained binary.
Struggled a bit with getting the reader/array to `Seek`, but finally
figured out `Cursor` and got it working. Cool.
|
|
Keep FFI functions separate from the rest.
