Feature Request: File logging relative to rails root only

[cshupp1]

When deploying to a J2EE server file names can get a little long when using %F in the formatter.

For example, this log message:
[ALWAYS][2016-01-12T10:27:06][/work/ETS/glassfish/glassfish4/glassfish/domains/domain1/applications/ets_tooling/WEB-INF/config/initializers/02_log_initializer.rb][59] Logging started.

Would look better as:
[ALWAYS][2016-01-12T12:57:07][/config/initializers/02_log_initializer.rb][108] Logging started!

opening the logging module and redefining the logging event as follows solves the issue for me (but this will only work on JRuby).

v = $VERBOSE
$VERBOSE = nil
module Logging
  #opening and redefining LogEvent found in log_event.rb

  LogEvent = Struct.new( :logger, :level, :data, :time, :file, :line, :method ) {

    # Regular expression used to parse out caller information
    #
    # * $1 == filename
    # * $2 == line number
    # * $3 == method name (might be nil)
    CALLER_RGXP = %r/([-\.\/\(\)\w]+):(\d+)(?::in `(\w+)')?/o
    #CALLER_INDEX = 2
    CALLER_INDEX = ((defined? JRUBY_VERSION and JRUBY_VERSION > '1.6') or (defined? RUBY_ENGINE and RUBY_ENGINE[%r/^rbx/i])) ? 1 : 2

    def initialize( logger, level, data, caller_tracing )
      f = l = m = ''

      if caller_tracing
        stack = Kernel.caller[CALLER_INDEX]
        return if stack.nil?

        match = CALLER_RGXP.match(stack)
        f = match[1]
        separator = java.io.File.separator
        last = Rails.root.to_s.split(separator).last
        f = f.split(last).last
        l = Integer(match[2])
        m = match[3] unless match[3].nil?
      end

      super(logger, level, data, Time.now, f, l, m)
    end
  }

end  # module Logging
#put warnings back to whatever they were.
$VERBOSE = v

I had the same request and solved it by monkey patching the LogEvent class that returns the filename:

module Logging
  # patch LogEvent class to only return file path relative to rails root instead of full path if set
  module LogEventExtensions
    def file
      self[:file].blank? ? self[:file] : Pathname.new(self[:file]).relative_path_from(::Rails.root).to_s
    end
  end

  class LogEvent
    prepend LogEventExtensions
  end
end

I just made an attempt to upgrade from 2.0.0 to 2.1.0. I cannot find the basepath in the source code anywhere. And obviously my references to it fail.

Thanks,

Ah, my apologies on that one. I just pushed up a new release - version 2.2.0 - that contains the basepath changes you are looking for.
