README
¶
This package contains a convenience function that takes a comma-separated
glob-style string and uses spacelog.SetLevel to set the log level
on all the matching loggers.
This is designed so that you can easily enable certain debug levels using
an environment variable or your other method of choice, similar to the NPM
module debug.
// From some variable
config := "incoming*,core*"
levelstring.Configure(config, spacelog.Debug)
// Or straight from the environment
levelstring.Configure(os.Getenv("DEBUG"), spacelog.Debug)
See http://godoc.org/github.com/dimfeld/spacelog-levelstring for more examples.
Limitations
Calls to Configure only affect logger names that exist at the time of the call. New
loggers created afterward will use the logger collection's default level.

Functions ¶
func Configure ¶
Configure sets all loggers matching a comma-separated glob-style string to the requested level.
Example ¶
spacelog.MustSetup("configure-example", spacelog.SetupConfig{
Output: "stdout",
Level: "info",
Format: "{{.Level}} {{.LoggerName}} - {{.Message}}",
})
inLogger := spacelog.GetLoggerNamed("input")
inputVerboseLogger := spacelog.GetLoggerNamed("input:verbose")
coreLogger := spacelog.GetLoggerNamed("core")
outLogger := spacelog.GetLoggerNamed("output")
outputVerboseLogger := spacelog.GetLoggerNamed("output:verbose")
print := func() {
// Only the enabled facilities will actually print
inLogger.Debug("input logger debug enabled")
inputVerboseLogger.Debug("input:verbose logger debug enabled")
coreLogger.Debug("core logger debug enabled")
outLogger.Debug("output logger debug enabled")
outputVerboseLogger.Debug("output:verbose logger debug enabled")
fmt.Println()
}
coreLogger.Info("Enabling input* DEBUG")
Configure("input*", spacelog.Debug)
print()
coreLogger.Info("Enabling *verbose DEBUG")
Configure("*verbose", spacelog.Debug)
print()
coreLogger.Info("Enabling all DEBUG")
Configure("*", spacelog.Debug)
print()
coreLogger.Info("Setting input:verb*, output:verbose back to WARN")
Configure("input:verb*, output:verbose", spacelog.Warning)
print()
Output: INFO core - Enabling input* DEBUG DEBUG input - input logger debug enabled DEBUG input:verbose - input:verbose logger debug enabled INFO core - Enabling *verbose DEBUG DEBUG input - input logger debug enabled DEBUG input:verbose - input:verbose logger debug enabled DEBUG output:verbose - output:verbose logger debug enabled INFO core - Enabling all DEBUG DEBUG input - input logger debug enabled DEBUG input:verbose - input:verbose logger debug enabled DEBUG core - core logger debug enabled DEBUG output - output logger debug enabled DEBUG output:verbose - output:verbose logger debug enabled INFO core - Setting input:verb*, output:verbose back to WARN DEBUG input - input logger debug enabled DEBUG core - core logger debug enabled DEBUG output - output logger debug enabled
