import "golazy.dev/lazytui/lazycli"Functions ¶
func Execute ¶
Execute draws and runs a command tree. It returns a process-style exit code.
func Execute(ctx context.Context, draw Drawer, config ExecuteConfig) intfunc Exit ¶
Exit returns an error that stops command execution with code without printing another diagnostic. A zero code returns nil.
func Exit(code int) errorfunc Func ¶
Func adapts func(context.Context, Params) error into a command controller.
func Func(handler any) anyfunc Main ¶
Main executes a drawer using the process arguments and streams.
func Main(draw Drawer)func Params[T any] ¶
Params returns the parsed parameter struct of type T for the invocation.
func Params[T any](ctx context.Context) Tfunc Stderr ¶
func Stderr(ctx context.Context) io.Writerfunc Stdin ¶
func Stdin(ctx context.Context) io.Readerfunc Stdout ¶
func Stdout(ctx context.Context) io.WriterTypes ¶
type Command ¶
Command configures one command scope. Empty presentation fields inherit from lower merged layers and, for Logo and Palette, from parent scopes.
type Command struct {
Name string
Help string
Description string
Hidden bool
Disabled bool
Default bool
Logo string
Palette lazytui.Palette
Controller any
Method string
Autocomplete bool
}type Controller ¶
Controller is a zero-size controller type reference. It lets a router expose method metadata without constructing the controller during help or completion.
type Controller[T any] struct{}type Drawer ¶
type Drawer func(Scope)type ExecuteConfig ¶
type ExecuteConfig struct {
Args []string
Stdin io.Reader
Stdout io.Writer
Stderr io.Writer
Name string
}type Scope ¶
Scope builds a command tree. Repeated definitions overlay the existing node; controllers are composed in definition order.
type Scope interface {
Root(Command)
Define(name string, command Command)
Group(name string, command Command, draw Drawer)
Merge(Drawer)
}
Package lazycli provides a small reflection-driven command router.
