The CLI sends single-character IPC commands to the daemon. The daemon owns lifecycle and runs a pipeline state machine that coordinates recording, transcription, optional LLM cleanup, and text injection. + +## Components +- CLI: command parsing and IPC client (`cmd/hyprvoice/main.go`). +- Daemon: IPC server, lifecycle, pipeline ownership (`internal/daemon/daemon.go`). +- Pipeline: state machine orchestration (`internal/pipeline/`). +- Recording: PipeWire capture (`internal/recording/`). +- Transcription: batch + streaming adapters (`internal/transcriber/`). +- LLM post-processing: adapters and prompt builders (`internal/llm/`). +- Injection: wtype/ydotool/clipboard backends (`internal/injection/`). +- Provider registry: model metadata and adapter selection (`internal/provider/`). +- Config manager: load/validate + hot reload (`internal/config/`). + +## IPC control plane +The daemon listens on a unix socket and accepts single-character commands. + +- Socket path: `~/.cache/hyprvoice/control.sock` (see `internal/bus/bus.go`). +- Command bytes: `t` toggle, `c` cancel, `s` status, `v` version, `q` quit. +- Responses are line-based: `OK ...`, `STATUS ...`, or `ERR ...`. + +The CLI writes one command byte and reads the response; the daemon maps commands to pipeline actions. + +## Pipeline state machine +The pipeline is a long-lived goroutine managed by the daemon. It exposes a small interface and uses channels to coordinate actions and notifications. + +States (from `internal/pipeline/pipeline.go`): + +`idle -> recording -> transcribing -> processing -> injecting -> idle` + +Key transitions: +- Toggle while idle: start recorder + transcriber, move to recording/transcribing. +- Inject action: stop recorder, finalize transcription, optional LLM processing, inject text. +- Cancel: stop current action and return to idle. + +Key interface (simplified): +- `Pipeline.Run()` starts the pipeline loop. +- `Pipeline.Stop()` stops the current run. +- `Pipeline.GetActionCh()` receives actions (toggle inject). +- `Pipeline.GetNotifyCh()` emits user-facing events. +- `Pipeline.GetErrorCh()` emits errors for the daemon to handle. + +## Recording +`internal/recording/recording.go` defines `Recorder` with `Start/Stop/IsRecording`. +The default implementation wraps `pw-record` and emits `AudioFrame` chunks on a buffered channel. + +## Transcription +`internal/transcriber/transcriber.go` defines the core interfaces: + +- `Transcriber`: lifecycle + `GetFinalTranscription()`. +- `BatchAdapter`: `Transcribe(audio, opts)` for full-file transcription. +- `StreamingAdapter`: `Start/SendChunk/Results/Finalize/Close` for realtime. + +`NewTranscriber()` selects between `SimpleTranscriber` (batch) and `StreamingTranscriber` (streaming) based on provider model metadata. Streaming adapters deliver incremental `TranscriptionResult` events and a final transcript on stop/finalize. + +## LLM post-processing +`internal/llm/llm.go` defines an `Adapter` interface with `Process(text, config)`. +Adapters (OpenAI, Groq) use a shared prompt builder in `internal/llm/prompt.go`. +The pipeline invokes LLM processing only if enabled in config. + +## Injection +`internal/injection/injection.go` defines `Injector` and an ordered list of backends. +`internal/injection/backend.go` defines the `Backend` interface (`Name/Available/Inject`). +Backends include: +- `wtype` (Wayland typing) +- `ydotool` (uinput typing) +- `wl-clipboard` fallback + +The injector tries backends in order and falls back to clipboard when typing fails. + +## Provider registry and adapter selection +Providers register themselves via `internal/provider/provider.go` and return model catalogs. +Each `Model` includes: +- `AdapterType` (which adapter to use) +- `Endpoint` and optional `StreamingEndpoint` +- `SupportedLanguages` and model capabilities + +`internal/provider/names.go` holds adapter constants and provider names. `internal/provider/model.go` implements language compatibility checks. `internal/provider/provider.go` exposes helpers like `GetModel`, `ModelsForLanguage`, and `ValidateModelLanguage`. + +## Language compatibility +`internal/language/language.go` defines the canonical language list and provider-specific formatting (ex: Deepgram locale mapping). Model-level language filters enforce compatibility at config time and runtime. + +## Config lifecycle and hot reload +`internal/config/load.go` loads config, applies defaults, and resolves env-based API keys. `internal/config/validate.go` enforces model/language compatibility and provider requirements. `internal/config/convert.go` converts config into runtime structs for the pipeline. + +`internal/config/manager.go` watches `~/.config/hyprvoice/config.toml` and triggers reloads with a debounce. The daemon wires `onConfigReload` to stop any running pipeline, refresh notifiers, and apply new settings without a restart. + +## Notifications and errors +The pipeline emits notification events and errors via channels.
