Types

type BareCommand

type BareCommand interface {
	Command
	Run(
		ctx context.Context,
		parsedLayers map[string]*layers.ParsedParameterLayer,
		ps map[string]interface{},
	) error
}

type Command

type Command interface {
	Description() *CommandDescription
}

type CommandDescription

type CommandDescription struct {
	Name      string                            `yaml:"name"`
	Short     string                            `yaml:"short"`
	Long      string                            `yaml:"long,omitempty"`
	Layout    *layout.Layout                    `yaml:"layout,omitempty"`
	Flags     []*parameters.ParameterDefinition `yaml:"flags,omitempty"`
	Arguments []*parameters.ParameterDefinition `yaml:"arguments,omitempty"`
	Layers    []layers.ParameterLayer           `yaml:"layers,omitempty"`

	Parents []string `yaml:",omitempty"`
	// Source indicates where the command was loaded from, to make debugging easier.
	Source string `yaml:",omitempty"`
}

CommandDescription contains the necessary information for registering a command with cobra. Because a command gets registered in a verb tree, a full list of Parents all the way to the root needs to be provided.

type GlazeCommand

type GlazeCommand interface {
	Command
	// Run is called to actually execute the command.
	//
	// NOTE(manuel, 2023-02-27) We can probably simplify this to only take parsed layers
	//
	// The ps and GlazeProcessor calls could be replaced by a GlazeCommand specific layer,
	// which would allow the GlazeCommand to parse into a specific struct. The GlazeProcessor
	// is just something created by the passed in GlazeLayer anyway.
	//
	// When we are just left with building a convenience wrapper for Glaze based commands,
	// instead of forcing it into the upstream interface.
