Log::Any::Adapter::Capture - phpMan

NAME
    Log::Any::Adapter::Capture - Adapter for capturing log messages into an
    arrayref

VERSION
    version 1.710

SYNOPSIS
      # temporarily redirect arrays of [ $level, $category, $message ] into an array
      Log::Any::Adapter->set( { lexically => \my $scope }, Capture => to => \my @array );

      # temporarily redirect just the text of log messages into an array
      Log::Any::Adapter->set( { lexically => \my $scope }, Capture => text => \my @array );

      # temporarily redirect the full argument list and context of each call, but only for
      # log levels 'info' and above.
      Log::Any::Adapter->set(
        { lexically => \my $scope },
        Capture =>
            format => 'structured',
            to => \my @array,
            log_level => 'info'
      );

DESCRIPTION
    This logging adapter provides a convenient way to capture log messages
    into a callback or arrayref of your choice without needing to write your
    own adapter. It is intended for cases where you want to temporarily
    capture log messages, such as showing them to a user of your application
    rather than having them written to a log file.

ATTRIBUTES
  to
    Specify a coderef or arrayref where the messages will be delivered. The
    content pushed onto the array or passed to the coderef depends on
    "format".

  format
    'messages'
          sub ( $level, $category, $message_text ) { ... }
          push @to, [ $level, $category, $message_text ];

        This is the default format. It passes/pushes 3 arguments: the name
        of the log level, the logging category, and the message text as a
        plain string.

    'text'
          sub ( $message_text ) { ... }
          push @to, $message_text;

        This format is the simplest, and only passes/pushes the text of the
        message.

    'structured'
          sub ( $level, $category, @message_parts, \%context? ) { ... }
          push @to, [ $level, $category, @message_parts, \%context? ];

        This passes/pushes the full information available about the call to
        the logging method. The @message_parts are the actual arguments
        passed to the logging method, and if the final argument is a
        hashref, it is the combined "context" from the logging proxy and any
        overrides passed to the logging method.

  log_level
    Like other logging adapters, this optional argument can filter out any
    log messages above the specified threshhold. The default is to pass
    through all messages regardless of level.

ATTRIBUTE ALIASES
    These are not actual attributes, just shortcuts for others:

  text
      text => $dest

    is shorthand for

      format => 'text', to => $dest

  structured
      structured => $dest

    is shorthand for

      format => 'structured', to => $dest
