Types ¶

type BuilderLogger ¶

type BuilderLogger struct {
	Log
	Stderr io.Writer
	Stdout io.Writer
}

BuilderLogger is the implementation of the Log interface for this project.

func Initialize ¶

func Initialize(quiet bool) *BuilderLogger

Initialize returns a BuilderLogger that either contains a null logger (that prints nothing) or a standard logger (from the log package) with project-specific output.

func (*BuilderLogger) Write ¶

func (logger *BuilderLogger) Write(p []byte) (n int, err error)

type Log ¶

type Log interface {
	Print(v ...interface{})
	Printf(format string, v ...interface{})
	Println(v ...interface{})
	Fatal(v ...interface{})
	Fatalf(format string, v ...interface{})
	Fatalln(v ...interface{})
	Panicf(format string, v ...interface{})
	Panicln(v ...interface{})
}

Log is the interface for all general logging methods.

type Logger ¶

type Logger interface {
	Log
	Write(p []byte) (int, error)
}

Logger is almost identical to Log except that it also contains the Write(p []byte) method so it can satisfy tye io.Writer interface. At some point, these two types should probably be combined.

type NullLogger ¶

type NullLogger struct{}

NullLogger is an exported symbol for the nullLogger struct.

func (*NullLogger) Fatal ¶

func (nl *NullLogger) Fatal(v ...interface{})

Fatal fatals.

func (*NullLogger) Fatalf ¶

func (nl *NullLogger) Fatalf(format string, v ...interface{})

Fatalf fatalfs.

func (*NullLogger) Fatalln ¶

func (nl *NullLogger) Fatalln(v ...interface{})

Fatalln fatallns.

func (*NullLogger) Panicf ¶

func (nl *NullLogger) Panicf(format string, v ...interface{})

Panicf panicfs.

func (*NullLogger) Panicln ¶

func (nl *NullLogger) Panicln(v ...interface{})

Panicln paniclns.

func (*NullLogger) Print ¶

func (nl *NullLogger) Print(v ...interface{})

Print prints.

func (*NullLogger) Printf ¶

func (nl *NullLogger) Printf(format string, v ...interface{})

Printf printfs.

func (*NullLogger) Println ¶

func (nl *NullLogger) Println(v ...interface{})

Println printlns.

func (*NullLogger) Write ¶

func (nl *NullLogger) Write(p []byte) (int, error)

Write writes.

type OutWriter ¶

type OutWriter struct {
	Log
	// contains filtered or unexported fields
}

An OutWriter is responsible for for implementing the io.Writer interface.

func NewOutWriter ¶

func NewOutWriter(logger Log, fmtString string) *OutWriter

NewOutWriter accepts a logger and a format string and returns an OutWriter. When written to, the OutWriter will take the input, split it into lines, and print it to the logger using the provided format string. The intended use case of this functionality is for printing nice, colorful messages

func (*OutWriter) Write ¶

func (ow *OutWriter) Write(p []byte) (n int, err error)

Write writes the provided bytes, one line at a time, after interpolating them into the provided format string, to the provided logger.
