Modern Log MinLevel

Home › Logging › Logging › MinLevel

MinLevel

Sets or returns the lowest level the logger emits; LOG_OFF silences it.

Syntax

MinLevel as LogLevel        '' get and set

Notes

• A property, so it reads and assigns like a field.
• Records below it are dropped before any sink sees them, so raising it costs nothing at the sinks.
• LOG_OFF silences the logger completely.
• A child from WithName or WithField starts from its parent's value.

Examples

#import "std/logs"
using logs

dim con as ConsoleSink
dim lg as Logger
lg.AddSink( @con )

print lg.MinLevel = LOG_TRACE    '' -1 (true) -- the default

lg.MinLevel = LOG_WARN
lg.Info( "dropped -- below MinLevel" )
lg.Warn( "emitted" )

'' LOG_OFF silences it entirely
lg.MinLevel = LOG_OFF
lg.Error( "not emitted either" )
print "done"
