Types

type GlogHandler

type GlogHandler struct {
	// contains filtered or unexported fields
}

GlogHandler is a log handler that mimics the filtering features of Google's glog logger: setting global log levels; overriding with callsite pattern matches; and requesting backtraces at certain positions.

func NewGlogHandler

func NewGlogHandler(h Handler) *GlogHandler

NewGlogHandler creates a new log handler with filtering functionality similar to Google's glog logger. The returned handler implements Handler.

func (*GlogHandler) BacktraceAt

func (h *GlogHandler) BacktraceAt(location string) error

BacktraceAt sets the glog backtrace location. When set to a file and line number holding a logging statement, a stack trace will be written to the Info log whenever execution hits that statement.

Unlike with Vmodule, the ".go" must be present.

func (*GlogHandler) Log

func (h *GlogHandler) Log(r *Record) error

Log implements Handler.Log, filtering a log record through the global, local and backtrace filters, finally emitting it if either allow it through.

func (*GlogHandler) SetHandler

func (h *GlogHandler) SetHandler(nh Handler)

SetHandler updates the handler to write records to the specified sub-handler.

func (*GlogHandler) Verbosity

func (h *GlogHandler) Verbosity(level Lvl)

Verbosity sets the glog verbosity ceiling. The verbosity of individual packages and source files can be raised using Vmodule.

func (*GlogHandler) Vmodule

func (h *GlogHandler) Vmodule(ruleset string) error

Vmodule sets the glog verbosity pattern.

The syntax of the argument is a comma-separated list of pattern=N, where the pattern is a literal file name or "glob" pattern matching and N is a V level.

For instance:

pattern="gopher.go=3"
 sets the V level to 3 in all Go files named "gopher.go"

pattern="foo=3"
 sets V to 3 in all files of any packages whose import path ends in "foo"

pattern="foo/*=3"
 sets V to 3 in all files of any packages whose import path contains "foo"
