SYNOPSIS

     use Log::Any::Adapter;
     Log::Any::Adapter->set('ScreenColoredLevel',
         # min_level => 'debug', # default is 'warning'
         # colors    => { trace => 'bold yellow on_gray', ... }, # customize colors
         # use_color => 1, # force color even when not interactive
         # stderr    => 0, # print to STDOUT instead of STDERR
         # formatter => sub { "LOG: $_[1]" }, # default none
     );

DESCRIPTION

    This Log::Any adapter prints log messages to screen (STDERR/STDOUT)
    colored according to level. It is just like
    Log::Log4perl::Appender::ScreenColoredLevel, even down to the default
    colors (with a tiny difference), except that you don't have to use
    Log::Log4perl. Of course, unlike Log4perl, it only logs to screen and
    has minimal features.

    Parameters:

      * min_level => STRING

      Set logging level. Default is warning. If LOG_LEVEL environment
      variable is set, it will be used instead. If TRACE environment
      variable is set to true, level will be set to 'trace'. If DEBUG
      environment variable is set to true, level will be set to 'debug'. If
      VERBOSE environment variable is set to true, level will be set to
      'info'.If QUIET environment variable is set to true, level will be
      set to 'error'.

      * use_color => BOOL

      Whether to use color or not. Default is true only when running
      interactively (-t STDOUT returns true).

      * colors => HASH

      Customize colors. Hash keys are the logging methods, hash values are
      colors supported by Term::ANSIColor.

      The default colors are:

       method/level                 color
       ------------                 -----
       trace                        yellow
       debug                        (none, terminal default)
       info, notice                 green
       warning                      bold blue
       error                        magenta
       critical, alert, emergency   red

      * stderr => BOOL

      Whether to print to STDERR, default is true. If set to 0, will print
      to STDOUT instead.

      * formatter => CODEREF

      Allow formatting message. If defined, message will be passed before
      being colorized. Coderef will be passed:

       ($self, $message)

      and is expected to return the formatted message.

      The default formatter can optionally prefix the message with extra
      stuffs, depending on the content of LOG_PREFIX environment variable,
      such as: elapsed time (e.g. [0.023ms]) if LOG_PREFIX is elapsed.

      NOTE: Log::Any 1.00+ now has a proxy object which allows
      formatting/customization of message before it is sent to adapter(s),
      so formatting does not have to be done on a per-adapter basis. As an
      alternative to this attribute, you can also consider using the proxy
      object or the (upcoming?) global proxy object.

ENVIRONMENT

    LOG_LEVEL, QUIET, VERBOSE, DEBUG, TRACE. These environment variables
    can set the default for min_level. See documentation about min_level
    for more details.

    LOG_PREFIX. The default formatter groks these variables. See
    documentation about formatter about more details.
