write log level in logged message

[bbottema]

Moved from pdorgambide/angular-logger#23

I would like to be able to see in logged messages which ones are ERROR or just WARN.

We could make prefixPattern to accept a third parameter corresponding to the log level used to log the message.

@pdesoyres, you mean to say you would like to add the text " DEBUG" or "ERROR" to the message prefix? Or do you want to see only a certain level of messages in the log excluding all other (above or below).

[pdesoyres]

@bbottema, yes I would like to see the log level ("DEBUG" for example) in the message prefix. This is because, when I read the output log, I want to see very easily the log level of the message.

@pdesoyres, what pattern would you like as a default? Currently it is '%s::[%s]> ' (timestamp, then context).

[pdesoyres]

@bbottema Something like '%s::[%s] [%s]> ' (timestamp; logLevel, context) may fit my need.

[bbottema]

Alright, should be solved in v1.1.0.

By default, the loglevel is not shown, unless sprintf.js is missing in which case angular-logger falls back to basic prefixpattern that includes the logging level.

To add logging level to the prefix pattern, simply add the third placeholder:

logEnhancerProvider.prefixPattern = '%s::[%s] [%s]> ';

@bbottema thank you for the fast implementation ! It works perfectly.
