# options for formatters:
#
# :match => regexp for matching a log line
# :color => what color the line should be
# :style => what style the line should be
# :priority => what order the formatters are applied in. higher numbers first.
# :match_level => only apply filter at the specified log level
# :level => make this line visible at this log level or higher
# :replace => replace the matched text
# :prepend => insert text at start of message
# :append => append text to end of message
# :exit => force the exit code to be this (does not interrupt program, just
# ensures a specific exit code when the program eventually exits)
