NAME

       Log::Any::Adapter::ScreenColoredLevel - Send logs to screen with colorized messages according to level

VERSION

       This document describes version 0.08 of Log::Any::Adapter::ScreenColoredLevel (from Perl distribution
       Log-Any-Adapter-ScreenColoredLevel), released on 2015-06-18.

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.
