wvlet / log

Fancy logging library for Scala

wvlet

The wvlet, pronounced as weave-let, is a new query language for all types of data, including SQL engines (DBMSs), local files, programing language objects, etc.

wvlet queries (.wv) are designed to be:

• Composable. wvlet queries can be defined as functions, which can be reused for other data processing.
• Reproducible. You can build a reproducible data procesing pipeline with time-window based incremental processing.

wvlet queries will be compiled into SQL queries and code for target programming languages.

log's Issues

Asynchronous logging support

Here are several examples found in other loggers:

• https://github.com/twitter/util/blob/develop/util-logging/src/main/scala/com/twitter/logging/QueueingHandler.scala
• https://logging.apache.org/log4j/log4j-2.3/manual/async.html

Javascript console color support

CSS based coloring seems supported in Chrome and Firefox:

We can add formatter for this.

Support Scala.js

Using this would be sufficient: https://github.com/scala-js/scala-js-java-logging

Allow setting log level from Javascript console

Add method for cleaning up existing log handlers

For battling with libraries that sets log handlers in the library code

Fix log rotation file suffix

Log rotation file suffix is a bit weird:

access.log                      
access.log-2016-08-08.0.log.gz
