Functions

func Filter 

func Filter(input <-chan Record, output chan<- Record, minLevel LogLevel, earliest, latest model.VirtualTime)

func GetLines 

func GetLines(filename string, lineNum uint32, count uint32) ([]string, error)

func LogColor 

func LogColor(level LogLevel, msg string) string

func LogColorRGB 

func LogColorRGB(level LogLevel) color.RGBA

LogColorRGB is for chart code, but it's kept here so that it can be synchronized with LogColor

func Parse 

func Parse(elfPaths []string, inputStream io.Reader, recordsOut chan<- Record, follow bool, fixTime bool) error

func ParseStream 

func ParseStream(inputStream io.Reader, outputCh chan<- []byte, junkCh chan<- []byte, follow bool) error

func Render 

func Render(record Record) string

func Renderer 

func Renderer(input <-chan Record, output io.Writer, srcPath string, full bool) error
