func New

func New(std StdLogger) logr.Logger

New returns a logr.Logger which is implemented by Go's standard log package.

Example: stdr.New(log.New(os.Stderr, "", log.LstdFlags))

You can also just instantiate your own:

var log = stdr.Logger{
        Std: log.New(os.Stderr, "", log.LstdFlags),
        Depth: 0
        Formatter: stdr.DefaultFormatter{},
}

func SetVerbosity

func SetVerbosity(v int) int

SetVerbosity sets the global level against which all info logs will be compared. If this is greater than or equal to the "V" of the logger, the message will be logged. A higher value here means more logs will be written. The previous verbosity value is returned.

SetVerbosity is concurrent-safe.

type DefaultFormatter

type DefaultFormatter struct {
    // TimestampFormat sets the format used to print log timestamp.
    // If TimestampFormat is set, make sure timestamp flags are off
    // for the std. logger. Otherwise there will be duplicate timestamp
    // in the output.
    TimestampFormat string
    // ForceQuote true quotes all fieldKeys and fieldValues using %q.
    ForceQuote bool
    // HideKeys true will show [fieldValue] instead of [fieldKey=fieldValue]
    HideKeys bool
}

func (DefaultFormatter) Format

func (f DefaultFormatter) Format(e Entry) string

Format a log entry.

type Entry

type Entry struct {
    // Err is an error being logged using `logr Error(err error ...)` method.
    Err error
    // Name is logger name. It constists of a series of name "segments"
    // added by successive calls to `logr WithName(name string)` method.
    Name string
    // Verbosity represents how little a log matters.
    // Level zero, the default, matters most. Increasing levels matter less and less.
    // Verbosity is specified using `logr V(level int)` method.
    Verbosity int
    // Message consists of a constant message attached to the the log line.
    // This should generally be a simple description of what's occuring,
    // and should never be a format string.
    // Message is spcified using `logr Info` method and `logr Error` method.
    Message string
    // KeyAndValues where keys are arbitrary strings, while values may be any Go value.
    // KeyAndValues specified using `logr WithValues`, `logr Info`, and `logr Error` method.
    KeysAndValues []interface{}
}

Entry is a log entry. It is used by Formatter to log format output.

type Formatter

type Formatter interface {
    Format(Entry) string
}

Formatter formats a log entry Entry.

type Logger

type Logger struct {
    Std StdLogger
    // DepthOffset biases the assumed number of call frames to the "true"
    // caller.  This is useful when the calling code calls a function which then
    // calls glogr (e.g. a logging shim to another API).  Values less than zero
    // will be treated as zero.
    Depth int
    // All log entries pass through the formatter before logged to Out. The
    // included formatter is `DefaultFormatter`.
    // You can easily implement your Formatter implements the `Formatter` interface, see the
    // or included formatters for example.
    Formatter Formatter
    // contains filtered or unexported fields
}

func (Logger) Enabled

func (l Logger) Enabled() bool

func (Logger) Error

func (l Logger) Error(err error, msg string, kvList ...interface{})

func (Logger) Info

func (l Logger) Info(msg string, kvList ...interface{})

func (Logger) V

func (l Logger) V(level int) logr.InfoLogger

func (Logger) WithName

func (l Logger) WithName(name string) logr.Logger

WithName returns a new logr.Logger with the specified name appended. stdr uses '/' characters to separate name elements. Callers should not pass '/' in the provided name string, but this library does not actually enforce that.

func (Logger) WithValues

func (l Logger) WithValues(kvList ...interface{}) logr.Logger

type StdLogger

type StdLogger interface {
    // Output is the same as log.Output and log.Logger.Output.
    Output(calldepth int, logline string) error
}

StdLogger is the subset of the Go stdlib log.Logger API that is needed for this adapter.
