Variables

var DefaultCaller = log.Caller(4)

DefaultCaller is an alternative to the go-kit object of the same name to account for wrapping

var DefaultTimestampUTC = log.DefaultTimestampUTC

DefaultTimestampUTC is a passthrough to the go-kit object of the same name

var NewFromKitLogger = NewFrom

NewFromKitLogger wraps a BaseLogger (e.g., go-kit) in our custom extension

Functions

func PatchStdLib

func PatchStdLib(l Logger)

PatchStdLib sets up the stdlib global logger to run through the provided one instead

Types

type BaseLogger

type BaseLogger interface {
	Log(keyvals ...interface{}) error
}

func BaseFrom

func BaseFrom(l Logger) BaseLogger

type Logger

type Logger interface {
	Log(keyvals ...interface{}) error
	Message(string, ...interface{})
	Err(string, error, ...interface{})
	Printf(string, ...interface{})
}

Logger is the extended logging interface for the corvee applications

func NewFrom

func NewFrom(l BaseLogger) Logger

NewFrom wraps a BaseLogger (e.g., go-kit) in our custom extension

func NewJSONLogger

func NewJSONLogger() Logger

NewJSONLogger creates a new logger that writes json to stdout

func NewLogfmtLogger

func NewLogfmtLogger() Logger

NewLogfmtLogger creates a new logger that writes logfmt to stdout

func With

func With(l Logger, keyvals ...interface{}) Logger

With wraps a logger so that every emitted line contains the provided key/val pairs

func WithContext

func WithContext(ctx context.Context, logger Logger, keyvals ...interface{}) Logger

WithContext wraps a logger to include the request_id from a context in log messages

func WithLevel

func WithLevel(l Logger, levelStr string) Logger

WithLevel wraps a logger to filter out logs lower than the designated level

func WithRequest

func WithRequest(req *http.Request, l Logger, keyvals ...interface{}) Logger

WithRequest wraps a logger with fields from a http.Request
