Functions

func Run 

func Run(
	st *store.Store,
	databasePath, user, activeProject, version string,
	options ...tea.ProgramOption,
) (err error)

Run opens the data-version watcher and runs the full-screen program. activeProject is the project local commands default to, resolved by the caller that owns the data directory; it opens the switcher and defaults the editor's mandatory project field, and may be empty. version is the build identifier the launch screen's meta row prints (spec section 10.6.5); the TUI cannot reach package main's build info, so the caller passes it in and an empty string renders the meta row with its left slot only. Program options are accepted for deterministic tests; production passes none.

Types

type DataVersionWatcher 

type DataVersionWatcher struct {
	// contains filtered or unexported fields
}

DataVersionWatcher compares PRAGMA data_version on one pinned SQLite connection. Values from pooled or replacement connections are unrelated and therefore useless for cross-process change detection.

func OpenDataVersionWatcher 

func OpenDataVersionWatcher(ctx context.Context, path string) (*DataVersionWatcher, error)

OpenDataVersionWatcher opens a dedicated, otherwise-idle connection to the board database. It never holds a transaction across polls.

func (*DataVersionWatcher) Close 

func (w *DataVersionWatcher) Close() error

Close releases the pinned connection and its one-connection pool.

func (*DataVersionWatcher) DataVersion 

func (w *DataVersionWatcher) DataVersion(ctx context.Context) (int64, error)

DataVersion reads SQLite's connection-local external-change counter.

type Model 

type Model struct {
	// contains filtered or unexported fields
}

Model is the single Bubble Tea root. It owns board state, focus, terminal dimensions, and all message routing; commands perform IO and only return messages, so Update remains deterministic.

func NewModel 

func NewModel(store boardReader, watcher dataVersionReader, user string) Model

NewModel creates the root model for one local board owner.

func (Model) Init 

func (m Model) Init() tea.Cmd

Init loads the first board snapshot and starts the external-write watcher.

func (Model) RenderPlanStats 

func (m Model) RenderPlanStats() RenderPlanStats

RenderPlanStats returns a value copy so instrumentation cannot mutate the frame or its revision graph.

func (*Model) SetActiveProject 

func (m *Model) SetActiveProject(name string)

SetActiveProject hands the board the project local commands default to (KB_PROJECT, else the project stored by kb project use). It is the switcher's opening scope and the editor's default for a new card; stored preferences override the scope, never the default.

func (*Model) SetVersion 

func (m *Model) SetVersion(version string)

SetVersion records the build version the launch screen's meta row prints. The TUI cannot reach package main's build info, so the string arrives on tui.Run and is stored here (spec section 10.6.5).

func (Model) Update 

func (m Model) Update(message tea.Msg) (tea.Model, tea.Cmd)

func (Model) View 

func (r Model) View() tea.View

View returns the complete immutable frame most recently installed by Update. Rendering, hit-map construction, and overlay composition happen only at the render-plan publication seam.

type RenderPlanRevisions 

type RenderPlanRevisions struct {
	Tasks      uint64 `json:"tasks"`
	Projection uint64 `json:"projection"`
	Layout     uint64 `json:"layout"`
	Appearance uint64 `json:"appearance"`
	Overlay    uint64 `json:"overlay"`
	Temporal   uint64 `json:"temporal"`
	Pointer    uint64 `json:"pointer"`
}

RenderPlanRevisions identifies the immutable inputs used to build the retained frame. Separate revisions keep layout invalidation independent from appearance invalidation instead of hiding both behind an unkeyed cache.

type RenderPlanStats struct {
	Revisions                      RenderPlanRevisions `json:"revisions"`

}

RenderPlanStats is the instrumentation seam used by the regression harness. DiscardedEvents and StaleWorkerResults are zero until their bounded-admission and worker slices land; reserving them here keeps one report contract.
