   # "complex" use
   use AnyEvent::Log;

   my $tracer = AnyEvent::Log::logger trace => \$my $trace;

   $tracer->("i am here") if $trace;
   $tracer->(sub { "lots of data: " . Dumper $self }) if $trace;

   # configuration

   # set logging for this package to maximum
   AnyEvent::Log::ctx->level ("all");

   # set logging globally to anything below debug
   (AnyEvent::Log::ctx "")->level ("notice");

   # see also EXAMPLES, below

   # disable logging for package "AnyEvent" and all packages below it
   AnyEvent->AnyEvent::Log::ctx->level (0);

   # log everything below debug to a file, for the whole program
   my $ctx = AnyEvent::Log::ctx;
   $ctx->log_cb (sub { print FILE shift; 0 });
   (AnyEvent::Log::ctx "")->add ($ctx);

=head1 DESCRIPTION

This module implements a relatively simple "logging framework". It doesn't
attempt to be "the" logging solution or even "a" logging solution for
AnyEvent - AnyEvent simply creates logging messages internally, and this
module more or less exposes the mechanism, with some extra spiff to allow
using it from other modules as well.

Remember that the default verbosity level is C<0>, so nothing will be
logged, unless you set C<PERL_ANYEVENT_VERBOSE> to a higher number before
starting your program, or change the logging level at runtime with
something like:

   use AnyEvent;
   (AnyEvent::Log::ctx "")->level ("info");

The design goal behind this module was to keep it simple (and small),
but make it powerful enough to be potentially useful for any module, and
extensive enough for the most common tasks, such as logging to multiple
targets, or being able to log into a database.

The amount of documentation might indicate otherwise, but the module is
still just 240 lines or so.

=head1 LOGGING FUNCTIONS

These functions allow you to log messages. They always use the caller's
package as a "logging module/source". Also, the main logging function is
callable as C<AnyEvent::log> or C<AE::log> when the C<AnyEvent> module is
loaded.

=item AnyEvent::Log::log $level, $msg[, @args]

Requests logging of the given C<$msg> with the given log level (1..9).
You can also use the following strings as log level: C<fatal> (1),
C<alert> (2), C<critical> (3), C<error> (4), C<warn> (5), C<note> (6),
C<info> (7), C<debug> (8), C<trace> (9).

For C<fatal> log levels, the program will abort.

If only a C<$msg> is given, it is logged as-is. With extra C<@args>, the
C<$msg> is interpreted as an sprintf format string.

The C<$msg> should not end with C<\n>, but may if that is convenient for
you. Also, multiline messages are handled properly.

Last not least, C<$msg> might be a code reference, in which case it is
supposed to return the message. It will be called only then the message
actually gets logged, which is useful if it is costly to create the
message in the first place.

Whether the given message will be logged depends on the maximum log level
and the caller's package.

Note that you can (and should) call this function as C<AnyEvent::log> or
C<AE::log>, without C<use>-ing this module if possible (i.e. you don't
need any additional functionality), as those functions will load the
logging module on demand only. They are also much shorter to write.

Also, if you optionally generate a lot of debug messages (such as when
tracing some code), you should look into using a logger callback and a
boolean enabler (see C<logger>, below).

Example: log something at error level.

   AE::log error => "something";

Example: use printf-formatting.

   AE::log info => "%5d %-10.10s %s", $index, $category, $msg;

Example: only generate a costly dump when the message is actually being logged.

   AE::log debug => sub { require Data::Dump; Data::Dump::dump \%cache };

*AnyEvent::log = *AE::log = \&log;

=item $logger = AnyEvent::Log::logger $level[, \$enabled]

Creates a code reference that, when called, acts as if the
C<AnyEvent::Log::log> function was called at this point with the givne
level. C<$logger> is passed a C<$msg> and optional C<@args>, just as with
the C<AnyEvent::Log::log> function:

   my $debug_log = AnyEvent::Log::logger "debug";

   $debug_log->("debug here");
   $debug_log->("%06d emails processed", 12345);
   $debug_log->(sub { $obj->as_string });

The idea behind this function is to decide whether to log before actually
logging - when the C<logger> function is called once, but the returned
logger callback often, then this can be a tremendous speed win.

Despite this speed advantage, changes in logging configuration will
still be reflected by the logger callback, even if configuration changes
I<after> it was created.

To further speed up logging, you can bind a scalar variable to the logger,
which contains true if the logger should be called or not - if it is
false, calling the logger can be safely skipped. This variable will be
updated as long as C<$logger> is alive.

Full example:

   # near the init section
   use AnyEvent::Log;

   my $debug_log = AnyEvent:Log::logger debug => \my $debug;

   # and later in your program
   $debug_log->("yo, stuff here") if $debug;

   $debug and $debug_log->("123");

Note: currently the enabled var is always true - that will be fixed in a
future version :)

=head1 LOGGING CONTEXTS

This module associates every log message with a so-called I<logging
context>, based on the package of the caller. Every perl package has its
own logging context.

A logging context has three major responsibilities: filtering, logging and
propagating the message.

For the first purpose, filtering, each context has a set of logging
levels, called the log level mask. Messages not in the set will be ignored
by this context (masked).

For logging, the context stores a formatting callback (which takes the
timestamp, context, level and string message and formats it in the way
it should be logged) and a logging callback (which is responsible for
actually logging the formatted message and telling C<AnyEvent::Log>
whether it has consumed the message, or whether it should be propagated).

For propagation, a context can have any number of attached I<parent
contexts>. Any message that is neither masked by the logging mask nor
masked by the logging callback returning true will be passed to all parent
contexts.

Each call to a logging function will log the message at most once per
context, so it does not matter (much) if there are cycles or if the
message can arrive at the same context via multiple paths.

=head2 DEFAULTS

By default, all logging contexts have an full set of log levels ("all"), a
disabled logging callback and the default formatting callback.

Package contexts have the package name as logging title by default.

They have exactly one parent - the context of the "parent" package. The
parent package is simply defined to be the package name without the last
component, i.e. C<AnyEvent::Debug::Wrapped> becomes C<AnyEvent::Debug>,
and C<AnyEvent> becomes ... C<AnyEvent::Log::Top> which is the
exception of the rule - just like the parent of any package name in
Perl is C<main>, the default parent of any top-level package context is
C<AnyEvent::Log::Top>.

Since perl packages form only an approximate hierarchy, this parent
context can of course be removed.

All other (anonymous) contexts have no parents and an empty title by
default.

When the module is loaded it creates the default context called
C<AnyEvent::Log::Default> (also stored in C<$AnyEvent::Log::Default>),
which simply logs everything via C<warn> and doesn't propagate anything
anywhere by default. The purpose of the default context is to provide
a convenient place to override the global logging target or to attach
additional log targets. It's not meant for filtering.

It then creates the root context called C<AnyEvent::Log::Root> (also
stored in C<$AnyEvent::Log::Root>) and sets its log level set to all
levels up to the one specified by C<$ENV{PERL_ANYEVENT_VERBOSE}>. It
then attached the default logging context to it. The purpose of the root
context is to simply provide filtering according to some global log level.

Finally it creates the top-level package context called
C<AnyEvent::Log::Top> (also stored in, you might have guessed,
C<$AnyEvent::Log::Top>) and attached the root context but otherwise leaves
it at default config. It's purpose is simply to collect all log messages
system-wide.

These three special contexts can also be referred to by the
package/context names C<AE::Log::Default>, C<AE::Log::Root> and
C<AE::Log::Top>.

The effect of all this is that log messages, by default, wander up
to the root context where log messages with lower priority then
C<$ENV{PERL_ANYEVENT_VERBOSE}> will be filtered away and then to the
AnyEvent::Log::Default context to be passed to C<warn>.

Splitting the top level context into three contexts makes it easy to set
a global logging level (by modifying the root context), but still allow
other contexts to log, for example, their debug and trace messages to the
default target despite the global logging level, or to attach additional
log targets that log messages, regardless of the global logging level.

It also makes it easy to replace the default warn-logger by something that
logs to a file, or to attach additional logging targets.

=head2 CREATING/FINDING/DESTROYING CONTEXTS

=over 4

=item $ctx = AnyEvent::Log::ctx [$pkg]

This function creates or returns a logging context (which is an object).

If a package name is given, then the context for that packlage is
returned. If it is called without any arguments, then the context for the
callers package is returned (i.e. the same context as a C<AE::log> call
would use).

If C<undef> is given, then it creates a new anonymous context that is not
tied to any package and is destroyed when no longer referenced.

=cut

sub ctx(;$) {
   my $pkg = @_ ? shift : (caller)[0];

   ref $pkg
      ? $pkg
      : defined $pkg
         ? $CTX{$pkg} ||= AnyEvent::Log::_pkg_ctx $pkg
         : bless [undef, (1 << 10) - 1 - 1], "AnyEvent::Log::Ctx"
}

=item AnyEvent::Log::reset

Resets all package contexts contexts and recreates the default hierarchy
if necessary, i.e. resets the logging subsystem to defaults.

This can be used to implement config-file (re-)loading: before loading a
configuration, reset all contexts.

Note that this currently destroys all logger callbacks - bug me if you
need this fixed :)

   # hard to kill complex data structures
   # we recreate all package loggers and reset the hierarchy
   while (my ($k, $v) = each %CTX) {

      my $pkg = $k =~ /^(.+)::/ ? $1 : "AE::Log::Top";
      $v->attach ($CTX{$pkg});
   }

   $AnyEvent::Log::Default->title ("AnyEvent::Log::Default");
   $AnyEvent::Log::Default->log_cb (sub {

=item $ctx = new AnyEvent::Log::Ctx methodname => param...

This is a convenience constructor that makes it simpler to construct
anonymous logging contexts.

Each key-value pair results in an invocation of the method of the same
name as the key with the value as parameter, unless the value is an
arrayref, in which case it calls the method with the contents of the
array. The methods are called in the same order as specified.

Example: create a new logging context and set both the default logging
level, some parent contexts and a logging callback.

   $ctx = new AnyEvent::Log::Ctx
      title   => "dubious messages",
      level   => "error",
      log_cb  => sub { print STDOUT shift; 0 },
      parents => [$ctx1, $ctx, $ctx2],

=head2 CONFIGURING A LOG CONTEXT

The following methods can be used to configure the logging context.

=over 4

=item $ctx->title ([$new_title])

Returns the title of the logging context - this is the package name, for
package contexts, and a user defined string for all others.

If C<$new_title> is given, then it replaces the package name or title.

=cut

sub title {
   $_[0][0] = $_[1] if @_ > 1;

=head3 LOGGING LEVELS

The following methods deal with the logging level set associated with the
log context.

The most common method to use is probably C<< $ctx->level ($level) >>,
which configures the specified and any higher priority levels.

All functions which accept a list of levels also accept the special string
C<all> which expands to all logging levels.

=over 4

=item $ctx->levels ($level[, $level...)

Enables logging for the given levels and disables it for all others.

=item $ctx->level ($level)

Enables logging for the given level and all lower level (higher priority)
ones. In addition to normal logging levels, specifying a level of C<0> or
C<off> disables all logging for this level.

Example: log warnings, errors and higher priority messages.

   $ctx->level ("warn");
   $ctx->level (5); # same thing, just numeric

=item $ctx->enable ($level[, $level...])

Enables logging for the given levels, leaving all others unchanged.

=item $ctx->disable ($level[, $level...])

Disables logging for the given levels, leaving all others unchanged.

=cut

sub _lvl_lst {
   map {
      $_ > 0 && $_ <= 9 ? $_+0
      : $_ eq "all"     ? (1 .. 9)

=head3 PARENT CONTEXTS

The following methods attach and detach another logging context to a
logging context.

Log messages are propagated to all parent contexts, unless the logging
callback consumes the message.

=over 4

=item $ctx->attach ($ctx2[, $ctx3...])

Attaches the given contexts as parents to this context. It is not an error
to add a context twice (the second add will be ignored).

A context can be specified either as package name or as a context object.

=item $ctx->detach ($ctx2[, $ctx3...])

Removes the given parents from this context - it's not an error to attempt
to remove a context that hasn't been added.

A context can be specified either as package name or as a context object.

=item $ctx->parents ($ctx2[, $ctx3...])

Replaces all parents attached to this context by the ones given.

=cut

sub attach {
   my $ctx = shift;

   $ctx->[2]{$_+0} = $_
      for map { AnyEvent::Log::ctx $_ } @_;
}

sub detach {
   my $ctx = shift;

   delete $ctx->[2]{$_+0}
      for map { AnyEvent::Log::ctx $_ } @_;
}

sub parents {
   undef $_[0][2];
   &attach;
}

=back

=head3 MESSAGE LOGGING

The following methods configure how the logging context actually does
the logging (which consists of formatting the message and printing it or
whatever it wants to do with it) and also allows you to log messages
directly to a context, without going via your package context.

=over 4

=item $ctx->log_cb ($cb->($str))

Replaces the logging callback on the context (C<undef> disables the
logging callback).

The logging callback is responsible for handling formatted log messages
(see C<fmt_cb> below) - normally simple text strings that end with a
newline (and are possibly multiline themselves).

It also has to return true iff it has consumed the log message, and false
if it hasn't. Consuming a message means that it will not be sent to any
parent context. When in doubt, return C<0> from your logging callback.

Example: a very simple logging callback, simply dump the message to STDOUT
and do not consume it.

   $ctx->log_cb (sub { print STDERR shift; 0 });

You can filter messages by having a log callback that simply returns C<1>
and does not do anything with the message, but this counts as "message
being logged" and might not be very efficient.

Example: propagate all messages except for log levels "debug" and
"trace". The messages will still be generated, though, which can slow down
your program.

   $ctx->levels ("debug", "trace");
   $ctx->log_cb (sub { 1 }); # do not log, but eat debug and trace messages

=item $ctx->fmt_cb ($fmt_cb->($timestamp, $ctx, $level, $message))

Replaces the formatting callback on the context (C<undef> restores the
default formatter).

The callback is passed the (possibly fractional) timestamp, the original
logging context, the (numeric) logging level and the raw message string and needs to
return a formatted log message. In most cases this will be a string, but
it could just as well be an array reference that just stores the values.

Example: format just the raw message, with numeric log level in angle
brackets.

   $ctx->fmt_cb (sub {
      my ($time, $ctx, $lvl, $msg) = @_;

      "<$lvl>$msg\n"
   });

Example: return an array reference with just the log values, and use
C<PApp::SQL::sql_exec> to store the emssage in a database.

   $ctx->fmt_cb (sub { \@_ });
   $ctx->log_cb (sub {
      my ($msg) = @_;

      sql_exec "insert into log (when, subsys, prio, msg) values (?, ?, ?, ?)",
               $msg->[0] + 0,
               "$msg->[1]",
               $msg->[2] + 0,
               "$msg->[3]";

      0
   });

=cut

sub log_cb {
   my ($ctx, $cb) = @_;

   $ctx->[3] = $cb;
}

sub fmt_cb {
   my ($ctx, $cb) = @_;

   $ctx->[4] = $cb;
}

=item $ctx->log ($level, $msg[, @params])

context.

This section shows some common configurations.

=over 4

=item Setting the global logging level.

Either put PERL_ANYEVENT_VERBOSE=<number> into your environment before
running your program, or modify the log level of the root context:

   PERL_ANYEVENT_VERBOSE=5 ./myprog

   $AnyEvent::Log::Root->level ("warn");

=item Append all messages to a file instead of sending them to STDERR.

This is affected by the global logging level.

   open my $fh, ">>", $path
      or die "$path: $!";

   $AnyEvent::Log::Default->log_cb (sub {
      syswrite $fh, shift;
      0
   });

=item Write all messages with priority C<error> and higher to a file.

This writes them only when the global logging level allows it, because
it is attached to the default context which is invoked I<after> global
filtering.

   open my $fh, ">>", $path
      or die "$path: $!";

   $AnyEvent::Log::Default->attach (new AnyEvent::Log::Ctx
      log_cb => sub { syswrite $fh, shift; 0 });

This writes them regardless of the global logging level, because it is
attached to the toplevel context, which receives all messages I<before>
the global filtering.

   $AnyEvent::Log::Top->attach (new AnyEvent::Log::Ctx
      log_cb => sub { syswrite $fh, shift; 0 });

In both cases, messages are still written to STDOUT.

=item Write trace messages (only) from L<AnyEvent::Debug> to the default logging target(s).

Attach the CyAnyEvent::Log::Default> context to the C<AnyEvent::Debug>
context and increase the C<AnyEvent::Debug> logging level - this simply
circumvents the global filtering for trace messages.

   my $debug = AnyEvent::Debug->AnyEvent::Log::ctx;
   $debug->attach ($AnyEvent::Log::Default);
   $debug->levels ("trace"); # not "level"!

This of course works for any package.
