type MatcherSet struct {
	// contains filtered or unexported fields

func NewMatcherSet(matchers []Matcher, verbose bool) MatcherSet

func (*MatcherSet) Match ¶ added in v1.0.0

func (m *MatcherSet) Match(str string, stderr bool) bool

Match returns whether all matchers either: * currently match the string and stream type (stdout/stderr) * have matched previously and closes the `done` channel if so.

type Tracker ¶

type Tracker struct {
	// contains filtered or unexported fields
}

Tracker allows to track stdout and stderr of running commands and wait for certain messages to appear

func NewTracker ¶

func NewTracker(cmd *exec.Cmd, logStdout, logStderr bool, prefixStdout, prefixStderr string) (*Tracker, error)

func (*Tracker) LogStderr ¶

func (t *Tracker) LogStderr(b bool)

func (*Tracker) LogStdout ¶

func (t *Tracker) LogStdout(b bool)

func (*Tracker) Match ¶

func (t *Tracker) Match(matchers []Matcher, verbose bool) chan struct{}

Match creates a MatcherSet, registers it and returns a channel that will be closed when all matchers have matched

func (*Tracker) Wait ¶
