Functions

func FileNameToFsFilePath

func FileNameToFsFilePath(fileName string) (fs.FS, string, error)

func GetParentsFromDir

func GetParentsFromDir(dir string) []string

GetParentsFromDir is a helper function to simply return a list of parent verbs for applications loaded from declarative yaml files. The directory structure mirrors the verb structure in cobra.

func LoadCommandAliasFromYAML

func LoadCommandAliasFromYAML(s io.Reader, options ...alias.Option) ([]*alias.CommandAlias, error)

func LoadCommandOrAliasFromReader

func LoadCommandOrAliasFromReader(
	r io.Reader,
	rawLoadCommand LoadReaderCommandFunc,
	options []cmds.CommandDescriptionOption,
	aliasOptions []alias.Option,
) ([]cmds.Command, error)

func LoadCommandsFromFS

func LoadCommandsFromFS(
	f fs.FS, dir string,
	loader CommandLoader,
	options []cmds.CommandDescriptionOption,
	aliasOptions []alias.Option,
) ([]cmds.Command, error)

LoadCommandsFromFS walks the FS and loads all commands and command aliases found.

Types

type CommandLoader

type CommandLoader interface {
	LoadCommands(
		f fs.FS, entryName string,
		options []cmds.CommandDescriptionOption,
		aliasOptions []alias.Option,
	) ([]cmds.Command, error)
	IsFileSupported(f fs.FS, fileName string) bool
}

CommandLoader is an interface that describes the most generic loader type, which is then used to load commands and command aliases from embedded queries and from "repository" directories used by glazed.

Examples of this pattern are used in sqleton, escuse-me and pinocchio.

type LoadReaderCommandFunc

type LoadReaderCommandFunc func(
	r io.Reader,
	options []cmds.CommandDescriptionOption,
	aliasOptions []alias.Option,
) ([]cmds.Command, error)
