Types

type Logger

type Logger struct {
	Writer io.Writer
}

func (*Logger) Error

func (l *Logger) Error(domain string, message string, args ...interface{})

Info logs an error message for the given log domain.

func (*Logger) Info

func (l *Logger) Info(domain string, message string, args ...interface{})

Info logs an info message for the given log domain.

func (*Logger) Pipe

func (l *Logger) Pipe(domain string, cmd *exec.Cmd)

Pipe logs the stdin and stdout of a process. The combined output is split by line, and each line is logged as an info message for the given log domain.

In the context of a CLI, this prefixes every line of output with the log domain, and helps readability when the outputs are multiplexed.

PipeReader logs the lines scanned from a reader. Each line is logged as an info message for the given log domain.

In the context of a CLI, this prefixes every line of output with the log domain, and helps readability when the outputs are multiplexed.
