And then execute:
$ bundle
Or install it yourself as:
$ gem install eventhub-components
Usage
require 'eventhub/components'
Pid Files
Takes care of writing, reading and deleting a PID file
pid_file = EventHub::Components::PidFile.new('my_application.pid')
pid_file.write # writes Process.pid
# or
pid_file.write(some_process_pid)
pid_file.read # => "some_pid" (it's a string as it comes from a file)
pid_file.delete
Logging
StructuredDataLogger
Provides a second argument (a hash) to the log methods (debug, info, ...)
logger = EventHub::Components::StructuredDataLogger.new(some_other_logger, 'app_name' => 'my fancy app', 'env' => 'staging')
logger.info("my message", :foo => 1, :bar => 2)
MultiLogger
Forwards calls to all devices that have been added to the multilogger.
logger = EventHub::Components::MultiLogger.new
logger.add_device(some_other_logger_1)
logger.add_device(some_other_logger_2)
logger.info("Hans")
ExceptionWriter
Helps writing exceptions and log messages to files. It creates
writer = EventHub::Components::ExceptionWriter.new() # logs to ./exceptions
# or
writer = EventHub::Components::ExceptionWriter.new('some_dir', max_number_of_files) # logs to ./exceptions/some_dir
writer.write(e)
