Overview ¶
Package cli contains initialisation functions for go-flags and go-logging. It facilitates sharing them between several projects.

Functions ¶
func MustGetLogger ¶
func MustGetLogger() *logging.Logger
MustGetLogger is a wrapper around go-logging's function of the same name. It automatically determines a logger name. The logger is registered and will be returned by ModuleLevels().
func MustGetLoggerNamed ¶
func MustGetLoggerNamed(name string) *logging.Logger
MustGetLoggerNamed is like MustGetLogger but lets the caller choose the name.
Types ¶
type LogLevelInfo ¶
type LogLevelInfo interface {
// ModuleLevels returns the level of all loggers retrieved by MustGetLogger().
ModuleLevels() map[string]logging.Level
// SetLevel modifies the level of a specific logger.
SetLevel(level logging.Level, module string)
}
A LogLevelInfo describes and can modify levels of the set of registered loggers.
func InitFileLogging ¶
func InitFileLogging(stderrVerbosity, fileVerbosity Verbosity, filename string) (LogLevelInfo, error)
InitFileLogging initialises logging backends, both to stderr and to a file. If the file path is empty then it will be ignored.
func InitLogging ¶
func InitLogging(verbosity Verbosity) LogLevelInfo
InitLogging initialises logging backends.
func InitStructuredLogging ¶
func InitStructuredLogging(stderrVerbosity, fileVerbosity Verbosity, filename string, structured bool) (LogLevelInfo, error)
InitStructuredLogging is like InitFileLogging but allows specifying whether the output should be structured as JSON.
func MustInitFileLogging ¶
func MustInitFileLogging(stderrVerbosity, fileVerbosity Verbosity, filename string) LogLevelInfo
MustInitFileLogging is like InitFileLogging but dies on any errors.
func MustInitStructuredLogging ¶
func MustInitStructuredLogging(stderrVerbosity, fileVerbosity Verbosity, filename string, structured bool) LogLevelInfo
MustInitStructuredLogging is like InitStructuredLogging but dies on any errors.
type Verbosity ¶
type Verbosity logging.Level
A Verbosity is used as a flag to define logging verbosity.
MaxVerbosity is the maximum verbosity we support.
MinVerbosity is the maximum verbosity we support.
func (*Verbosity) UnmarshalFlag ¶
UnmarshalFlag implements flag parsing. It accepts input in three forms: As an integer level, -v 4 (where -v 1 == warning & error only) As a named level, -v debug As a series of flags, -vvv (but note that bare -v does *not* work)
