Log::Any::Adapter::File - Simple adapter for logging to files
=head1 VERSION
version 1.038
=head1 SYNOPSIS
use Log::Any::Adapter ('File', '/path/to/file.log');
# or
use Log::Any::Adapter;
...
Log::Any::Adapter->set('File', '/path/to/file.log');
# with minimum level 'warn'
use Log::Any::Adapter (
'File', '/path/to/file.log', log_level => 'warn',
);
=head1 DESCRIPTION
This simple built-in L<Log::Any|Log::Any> adapter logs each message to the
specified file, with a datestamp prefix and newline appended. The file is
opened for append with autoflush on. If C<flock> is available, the handle
will be locked when writing.
The C<log_level> attribute may be set to define a minimum level to log.
The C<binmode> attribute may be set to define a PerlIO layer string to use
when opening the file. The default is C<:utf8>.
Category is ignored.
