tinylog singlelevel cw

A tinylog console writer extension to restrict writers to single log levels.

Features

The singlelevel-cw extends tinylog with the singlelevel-console parameter to restrict log outputs to the corresponding level. This supports debugging by defining multiple writers and print exactly the log-levels you need (e.g. traces, warnings, and errors).

   tinylog.writer              = singlelevel-console 
   tinylog.writer.singlelevel  = <true|false>

Example

The following screenshot shows the example where messages are logged to all log-levels (see Main.java) but the singlelevel-cw prints only the log-levels trace, warn and error are printed (here in Eclipse using the 'err ' stream for warn/error). This is realized by defining multiple writers, one per log-level and all restricted to the corresponding level, but activating only the needed ones.

You can reproduce the example by running mvn clean install and then java -jar target/tinylog-singlelevel-cw-1.3.1-executable.jar.

Maven artifact

Add the following dependency to use the singlelevel-cw in your maven project:

<dependency>
	<groupId>com.github.tobiasrm</groupId>
	<artifactId>tinylog-singlelevel-cw</artifactId>
	<version>1.3.1</version>
</dependency>

Comments

• Versioning. The versioning (see pom.xml) uses the original tinylog versions, e.g. tinylog-singlelevel-cw in version 1.3.1 uses tinylog v1.3.1. If needed, you may simply exclude it and use another tinylog version.
• Patched Configuration class. The singlelevel-cw implements the tinylog writer interface and is based on the tinylog consolewriter implementation. However, as the original tinylog Configuration does not provide the access on writer specific levels, a patch is provided with this project. The modifications are highlighted in the screenshots one and two. Of course, feel invited to diff with the original version.

Other tinylog writer extensions

• tinylog-coloredconsole for colored log-level and arbitrary source-code generated data through custom tags.
• tinylog-tagging-filewriter extension to remove custom strings (e.g. the tinylog-coloredconsole custom tags) before writing to file (based on filewriter)
• tinylog-tagging-rollingfilewriter extension to remove custom strings (e.g. the tinylog-coloredconsole custom tags) before writing to file (based on rollingfilewriter)
