Print only by clojure code
Hi guys, I have developed a very very little application in clojure that use an external lib in java that i prefer do not touch. The problem is that this lib for some weird reason (debug i guess) print at video a bunch of information useless for me, there is any way to avoid this problem, i mean can i just print what the clojure code actually print and not what also the lib in java print ? I'm sorry for my English... -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Print only by clojure code
It's logging, and assuming the logging implementation it is using log4j, you can specify the logging properties in a properties file, as system properties, or set the properties in code. The easiest way is to place a file called log4j.properties on the classpath (in the resources directory of your project) containing the following: # set root logger level to OFF (OFF, FATAL, ERROR, WARN, INFO, DEBUG, TRACE, ALL) log4j.rootLogger=OFF On Wed, Feb 8, 2012 at 1:49 PM, Simone Mosciatti mweb@gmail.com wrote: Hi guys, I have developed a very very little application in clojure that use an external lib in java that i prefer do not touch.

Re: Print only by clojure code
Piggy-backing off Mark's answer, if it is log4j that's being used, you can also use log4j.properties to set different logging levels for your Java code vs. your Clojure code (assuming the code are in different packages): http://stackoverflow.com/questions/3569395/filtering-out-log4j-messages-from-third-party-frameworks On Wednesday, February 8, 2012 11:40:45 AM UTC-8, Mark Rathwell wrote: It's logging, and assuming the logging implementation it is using log4j, you can specify the logging properties in a properties file, as system properties, or set the properties in code.

Re: Print only by clojure code
Tassilo: I don't know it , but it is the most likely probability. One would hope that if a library is dumping to the console, or anywhere, it is done through a standard logging lib configurable by the client. If it turned out not to be the case, it would be evident quickly, and then try other possibilities.
