Module std.experimental.logger.core

Functions

Name Description
globalLogLevel This methods get and set the global LogLevel.
isLoggingEnabled This functions is used at runtime to determine if a LogLevel is active. The same previously defined version statements are used to disable certain levels. Again the version statements are associated with a compile unit and can therefore not disable logging in other compile units. pure bool isLoggingEnabled()(LogLevel ll) @safe nothrow @nogc
log This function logs data.
log This function logs data.
log This function logs data.
log This function logs data.
logf This function logs data in a printf-style manner.
logf This function logs data in a printf-style manner.
logf This function logs data in a printf-style manner.
logf This function logs data in a printf-style manner.
sharedLog This property sets and gets the default Logger.
stdThreadLocalLog This function returns a thread unique Logger, that by default propergates all data logged to it to the sharedLog.

Classes

Name Description
Logger This class is the base of every logger. In order to create a new kind of logger a deriving class needs to implement the writeLogMsg method. By default this is not thread-safe.
StdForwardLogger The StdForwardLogger will always forward anything to the sharedLog.

Enums

Name Description
LogLevel There are eight usable logging level. These level are all, trace, info, warning, error, critical, fatal, and off. If a log function with LogLevel.fatal is called the shutdown handler of that logger is called.

Templates

Name Description
defaultLogFunction This template provides the global log functions with the LogLevel is encoded in the function name.
defaultLogFunctionf This template provides the global printf-style log functions with the LogLevel is encoded in the function name.
isLoggingActiveAt This template evaluates if the passed LogLevel is active. The previously described version statements are used to decide if the LogLevel is active. The version statements only influence the compile unit they are used with, therefore this function can only disable logging this specific compile unit.
moduleLogLevel This template returns the LogLevel named "logLevel" of type LogLevel defined in a user defined module where the filename has the suffix "loggerconfig.d". This LogLevel sets the minimal LogLevel of the module.

Enum values

Name Type Description
isLoggingActive This compile-time flag is true if logging is not statically disabled.
moduleLogLevel This template returns the LogLevel named "logLevel" of type LogLevel defined in a user defined module where the filename has the suffix "loggerconfig.d". This LogLevel sets the minimal LogLevel of the module.

Aliases

Name Type Description
critical This function logs data to the stdThreadLocalLog, optionally depending on a condition.
criticalf This function logs data to the sharedLog in a printf-style manner.
error This function logs data to the stdThreadLocalLog, optionally depending on a condition.
errorf This function logs data to the sharedLog in a printf-style manner.
fatal This function logs data to the stdThreadLocalLog, optionally depending on a condition.
fatalf This function logs data to the sharedLog in a printf-style manner.
info This function logs data to the stdThreadLocalLog, optionally depending on a condition.
infof This function logs data to the sharedLog in a printf-style manner.
trace This function logs data to the stdThreadLocalLog, optionally depending on a condition.
tracef This function logs data to the sharedLog in a printf-style manner.
warning This function logs data to the stdThreadLocalLog, optionally depending on a condition.
warningf This function logs data to the sharedLog in a printf-style manner.
