	FormBaseStyle   lipgloss.Style
	FormHeaderStyle lipgloss.Style
)

Active theme state. Populated by applyTheme; switched once at startup via SetTheme. These are package-level so existing call sites (util.Theme, util.Accented, util.Fg, …) keep working; they are read at render time, which always happens after the theme is selected.

Functions

func Accent added in v2.16.5

func Accented(text string) string

Confirm is a yes/no select styled by the active theme.

func CopyFile 

func CopyFile(src, dest string) error

func ToUnixPath(p string) string

Converts a path (possibly Windows-style) to a Unix-style path.

func UseTempPath 

func UseTempPath(permanentPath string) (string, func() error, func() error)

Provides a temporary path, a function to relocate it to a permanent path, and a function to clean up the temporary path that should always be deferred in the case of a failure to relocate.

Types

type ConsoleURLParams added in v2.16.1 

type ConsoleURLParams struct {
	AgentName    string            `url:"agentName,omitempty"`
	JobMetadata  string            `url:"jobMetadata,omitempty"`
	RoomName     string            `url:"roomName,omitempty"`
	RoomMetadata string            `url:"roomMetadata,omitempty"`
	Identity     string            `url:"identity,omitempty"`
	Metadata     string            `url:"metadata,omitempty"`
	Attributes   map[string]string `url:"attributes,omitempty"`
	Hidden       bool              `url:"hidden,omitempty"`
	AutoStart    bool              `url:"autoStart,omitempty"`
}

type OpenTarget added in v2.4.13 

type OpenTarget string
const (
	OpenTargetMeet    OpenTarget = "meet"
	OpenTargetConsole OpenTarget = "console"
)

type Printer added in v2.16.5 

type Printer struct {
	Out   io.Writer // primary output: data the user might pipe or redirect
	Err   io.Writer // status, warnings, diagnostics
	Quiet bool      // suppresses Status (warnings and errors still print)
	// contains filtered or unexported fields
}

Printer is a single sink for human-facing CLI output. One instance per process is initialized from the root command and reused everywhere, so all status, warning, and result lines share consistent streams and gating.

func NewPrinter added in v2.16.5 

func NewPrinter(out, err io.Writer, quiet bool) *Printer

NewPrinter builds a Printer targeting the given writers. Pass nil to default to os.Stdout / os.Stderr; this is the path tests use with bytes.Buffer.

func (*Printer) Await added in v2.16.5 

func (p *Printer) Await(title string, ctx context.Context, action func(ctx context.Context) error) error

Await runs action while showing a spinner, then returns the action's error.

The spinner is decoration: it only animates when the Printer targets an interactive terminal and is not in quiet mode. Otherwise Await emits the title once as a plain status line (itself suppressed by --quiet) and runs the action without animation, so redirected/piped/CI output stays free of escape sequences and --quiet stays silent.

func (*Printer) Result added in v2.16.5 

func (p *Printer) Result(a ...any)

Result writes the command's primary output to stdout. Always printed.

func (*Printer) ResultWriter added in v2.16.5 

func (p *Printer) ResultWriter() io.Writer

ResultWriter is the streaming counterpart of Result: always printed.

func (*Printer) Resultf added in v2.16.5 

func (p *Printer) Resultf(format string, a ...any)

Resultf is Printf-style Result.

func (*Printer) Status added in v2.16.5 

func (p *Printer) Status(a ...any)

Status writes an informational breadcrumb to stderr ("Using project [X]", "Cloning template…"). Suppressed by --quiet. A trailing newline is appended.

func (*Printer) StatusWriter added in v2.16.5 

func (p *Printer) StatusWriter() io.Writer

StatusWriter is the streaming counterpart of Status: io.Discard under --quiet.

func (*Printer) Statusf added in v2.16.5 

func (p *Printer) Statusf(format string, a ...any)

Statusf is Printf-style Status.

func (*Printer) WarnWriter added in v2.16.5 

func (p *Printer) WarnWriter() io.Writer

WarnWriter is the streaming counterpart of Warnf: never silenced.

func (*Printer) Warnf added in v2.16.5 

func (p *Printer) Warnf(format string, a ...any)

Warnf writes a warning to stderr. NOT suppressed by --quiet — warnings are always worth surfacing.

type ThemeName added in v2.16.5 

type ThemeName string

ThemeName identifies a color theme. The active theme is selected once at startup (see SetTheme) from the value persisted in the CLI config. 

const (
	// ThemeDefault uses only ANSI palette colors, so it adapts to the user's terminal
	// color scheme. This is the original look.
	ThemeDefault ThemeName = "default"
	// ThemeLiveKit uses the LiveKit brand palette (truecolor hex with light/dark variants).
	ThemeLiveKit ThemeName = "livekit"
)
