K9LogPatternFormatter is flexible logging message formatter configurable with pattern string (inspired by Log4j PatternLayout). It includes a formatter implementation for CocoaLumberjack. Writing a new formatter for other framework is easy.

Usage

#import <CocoaLumberjack/CocoaLumberjack.h>
#import <K9LogPatternFormatter/K9LogLumberjackPatternFormatter.h>

...
id<DDLogger> consoleLogger = [DDTTYLogger sharedInstance];

consoleLogger.logFormatter = [[K9LogLumberjackPatternFormatter alloc] initWithPattern:@"%.1p: %m"];

[DDLog addLogger:consoleLogger];

Supported patterns:

%d{pattern} timestamp formatted by using NSDateFormatter
- %d{HH':'mm':'ss} prints 14:34:02
- Threre are some predefined formats:
  1. %d{ISO8601} prints 2014-03-12 14:34:02,781
  2. %d{ISO8601_BASIC} prints 20140312 143402,781
  3. %d{ABSOLUTE} prints 14:34:02,781
  4. %d{DATE} prints 12 Mar 2014 14:34:02,781
  5. %d{COMPACT} prints 20140312143402781
- If no format is given, ISO8601 is used.
%m message
%p log level
%F file name without extension
%l file path
%L line number
%M function or method name
%% single percent sign ('%')

Min/max width modifier is also supported:

%20m Left pad with spaces and min width = 20
%-5m Right pad with spaces and min width = 5
%.10m Truncate if message is longer than 10
%-5.10m Right pad with spaces and min:5, max:10

For example, if the conversion pattern is @"[%-5p] %d{HH':'mm':'ss} %m", it would yield the output:

[DEBUG] 00:45:20 Message1
[WARN ] 00:45:21 Message2

@"%.1p: %m at %F:%L" would yield:

D: Message1 at File1:15
W: Message2 at File2:32

Requirements

Mac OS X 10.9
iOS 7.0
Xcode 7
