Log

Logs a message at a level you pass, or returns a record to add fields to.

Syntax

Log( lv ) as LogEvent
Log( lv, m )

Notes

• and the same six taking a message

Examples

#import "std/logs"
using logs

'' The process-wide logger is DefaultLogger( ), set up with LogInit and
'' used by the LogInfo-style macros. An explicit Logger, as here, is the
'' alternative when a part of the program wants its own sinks.
dim con as ConsoleSink
dim lg as Logger
lg.AddSink( @con )

'' Log( ) takes the level as an argument; the six named methods are the
'' same call with the level baked in
lg.Log( LOG_INFO, "starting" )
lg.Info( "started" )

'' Each also has a no-argument form returning a LogEvent to add fields to
lg.Log( LOG_WARN ).AddText( "disk", "C:" ).Msg( "almost full" )
