This is required since bundler support seems to be broken right now on
the default "image" of jruby-head on Travis. If we install it explicitly
(or update it to the latest version on all other Rubies), we will be
fine though.
Using methods named after the severity, users can esily log messages
based on their intended severity. We do support the block syntax
throughout to conditionally log expensive messages only if the log level
is low enough:
logger.debug { compute_details_for_log }
The Rackstash::Logger class will server as the public main entry point
for users. It will eventually implement the mostly complete interface of
Ruby's Logger.
The idea of Rackstash is the we will allow to buffer multiple log
messages allong with additional data until a combined log event is
eventually flushed to an underlying log target. This allows to keep
connected log messages and data as a single unit from the start without
having to painstakingly parse and connect these in later systems again.
We wnumerate exact Ruby versions in .travis.yml. This is required for
at least Ruby 2.4 which isn't currently recognized as a fuzzy match in
Travis' RVM version. When specifying it as an exact version, it will
install it though.
We specify all the other versions too since this makes our tests more
reproducable over time.
Since this is a complete rewrite of the original rackstash gem which got
up to v0.1, we start directly on 0.2 with our development and will
eventually release it as v0.2.
