Functions

func Concat

func Concat(pluginArgs [][2]string) string

Concat joins the given array of key=value formatted strings into a single ; delimited string.

func DownloadPlugin

func DownloadPlugin(source PluginSource, targetPath string) error

func FindInPaths

func FindInPaths(plugin string, paths []string) (string, error)

FindInPaths returns the full path of the plugin executable by searching in the provided list of paths

func MergeDuplicateEnviron

func MergeDuplicateEnviron(env []string) []string

MergeDuplicateEnviron returns a copy of environment variables with any duplicates removed, and keeping the latest values. Only variables of format "key=value" are considered for merging.

Types

type DefaultExecutor

type DefaultExecutor struct {
	Stderr io.Writer
}

DefaultExecutor finds the plugin executable and invokes it as a os command

func (*DefaultExecutor) ExecutePlugin

func (e *DefaultExecutor) ExecutePlugin(ctx context.Context, pluginPath string, cmdArgs []string, stdinData []byte, environ []string) ([]byte, error)

return the command output and the error

func (*DefaultExecutor) FindInPaths

func (e *DefaultExecutor) FindInPaths(plugin string, paths []string) (string, error)

type Error

type Error struct {
	Code    uint   `json:"code"`
	Msg     string `json:"msg"`
	Details string `json:"details,omitempty"`
}

Error describes an error during plugin execution

func NewError

func NewError(code uint, msg, details string) *Error

NewError creates new Error

func (*Error) Error

func (e *Error) Error() string

func (*Error) Print

func (e *Error) Print() error

type Executor

type Executor interface {
	// ExecutePlugin executes the plugin with the given parameters
	ExecutePlugin(ctx context.Context, pluginPath string, cmdArgs []string, stdinData []byte, environ []string) ([]byte, error)
	// FindInPaths finds the plugin in the given paths
	FindInPaths(plugin string, paths []string) (string, error)
}

Executor is an interface that defines methods to lookup a plugin and execute it.

type PluginArgs

type PluginArgs interface {
	AsEnviron() []string
}

type PluginSource

type PluginSource struct {
	Artifact     string                          `json:"artifact"`
	AuthProvider authprovider.AuthProviderConfig `json:"authProvider,omitempty"`
}

func ParsePluginSource

func ParsePluginSource(source interface{}) (PluginSource, error)
