+=head1 DESCRIPTION
-=head1 NAME
+Major benefits:
-Log::Contextual - Super simple logging interface
+=over 2
-=head1 SYNOPSIS
+=item * Efficient
+
+The logging functions take blocks, so if a log level is disabled, the
+block will not run:
+
+ # the following won't run if debug is off
+ log_debug { "the new count in the database is " . $rs->count };
+
+Similarly, the C<D> prefixed methods only C<Dumper> the input if the level is
+enabled.
+
+=item * Handy
+
+The logging functions return their arguments, so you can stick them in
+the middle of expressions:
+
+ for (log_debug { "downloading:\n" . join qq(\n), @_ } @urls) { ... }
+
+=item * Generic
+
+C<Log::Contextual> is an interface for all major loggers. If you log through
+C<Log::Contextual> you will be able to swap underlying loggers later.
+
+=item * Powerful
+
+C<Log::Contextual> chooses which logger to use based on L<< user defined C<CodeRef>s|/LOGGER CODEREF >>.
+Normally you don't need to know this, but you can take advantage of it when you
+need to later
+
+=item * Scalable
+
+If you just want to add logging to your extremely basic application, start with
+L<Log::Contextual::SimpleLogger> and then as your needs grow you can switch to
+L<Log::Dispatchouli> or L<Log::Dispatch> or L<Log::Log4perl> or whatever else.
+
+=back
+
+This module is a simple interface to extensible logging. It exists to
+abstract your logging interface so that logging is as painless as possible,
+while still allowing you to switch from one logger to another.
+
+It is bundled with a really basic logger, L<Log::Contextual::SimpleLogger>,
+but in general you should use a real logger instead of that. For something
+more serious but not overly complicated, try L<Log::Dispatchouli> (see
+L</SYNOPSIS> for example.)
+
+=head1 A WORK IN PROGRESS
+
+This module is certainly not complete, but we will not break the interface
+lightly, so I would say it's safe to use in production code. The main result
+from that at this point is that doing:
use Log::Contextual;
- my $logger = WarnLogger->new;
- my $logger2 = FileLogger->new;
+will die as we do not yet know what the defaults should be. If it turns out
+that nearly everyone uses the C<:log> tag and C<:dlog> is really rare, we'll
+probably make C<:log> the default. But only time and usage will tell.
- set_logger { $logger };
+=head1 IMPORT OPTIONS
- log_debug { "program started" };
+See L</SETTING DEFAULT IMPORT OPTIONS> for information on setting these project
+wide.
- sub foo {
- with_logger {
- log_trace { "foo entered" };
- # ...
- log_trace { "foo left" };
- } $logger2;
- }
+=head2 -logger
-=head1 DESCRIPTION
+When you import this module you may use C<-logger> as a shortcut for
+L<set_logger>, for example:
+
+ use Log::Contextual::SimpleLogger;
+ use Log::Contextual qw( :dlog ),
+ -logger => Log::Contextual::SimpleLogger->new({ levels => [qw( debug )] });
+
+sometimes you might want to have the logger handy for other stuff, in which
+case you might try something like the following:
+
+ my $var_log;
+ BEGIN { $var_log = VarLogger->new }
+ use Log::Contextual qw( :dlog ), -logger => $var_log;
+
+=head2 -levels
+
+The C<-levels> import option allows you to define exactly which levels your
+logger supports. So the default,
+C<< [qw(debug trace warn info error fatal)] >>, works great for
+L<Log::Log4perl>, but it doesn't support the levels for L<Log::Dispatch>. But
+supporting those levels is as easy as doing
-This module is for simplistic but very extensible logging.
+ use Log::Contextual
+ -levels => [qw( debug info notice warning error critical alert emergency )];
+
+=head2 -package_logger
+
+The C<-package_logger> import option is similar to the C<-logger> import option
+except C<-package_logger> sets the the logger for the current package.
+
+Unlike L</-default_logger>, C<-package_logger> cannot be overridden with
+L</set_logger>.
+
+ package My::Package;
+ use Log::Contextual::SimpleLogger;
+ use Log::Contextual qw( :log ),
+ -package_logger => Log::Contextual::WarnLogger->new({
+ env_prefix => 'MY_PACKAGE'
+ });
+
+If you are interested in using this package for a module you are putting on
+CPAN we recommend L<Log::Contextual::WarnLogger> for your package logger.
+
+=head2 -default_logger
+
+The C<-default_logger> import option is similar to the C<-logger> import option
+except C<-default_logger> sets the the B<default> logger for the current package.
+
+Basically it sets the logger to be used if C<set_logger> is never called; so
+
+ package My::Package;
+ use Log::Contextual::SimpleLogger;
+ use Log::Contextual qw( :log ),
+ -default_logger => Log::Contextual::WarnLogger->new({
+ env_prefix => 'MY_PACKAGE'
+ });
+
+=head1 SETTING DEFAULT IMPORT OPTIONS
+
+Eventually you will get tired of writing the following in every single one of
+your packages:
+
+ use Log::Log4perl;
+ use Log::Log4perl ':easy';
+ BEGIN { Log::Log4perl->easy_init($DEBUG) }
+
+ use Log::Contextual -logger => Log::Log4perl->get_logger;
+
+You can set any of the import options for your whole project if you define your
+own C<Log::Contextual> subclass as follows:
+
+ package MyApp::Log::Contextual;
+
+ use base 'Log::Contextual';
+
+ use Log::Log4perl ':easy';
+ Log::Log4perl->easy_init($DEBUG)
+
+ sub arg_default_logger { $_[1] || Log::Log4perl->get_logger }
+ sub arg_levels { [qw(debug trace warn info error fatal custom_level)] }
+
+ # or maybe instead of default_logger
+ sub arg_package_logger { $_[1] }
+
+ # and almost definitely not this, which is only here for completeness
+ sub arg_logger { $_[1] }
+
+Note the C<< $_[1] || >> in C<arg_default_logger>. All of these methods are
+passed the values passed in from the arguments to the subclass, so you can
+either throw them away, honor them, die on usage, or whatever. To be clear,
+if you define your subclass, and someone uses it as follows:
+
+ use MyApp::Log::Contextual -default_logger => $foo,
+ -levels => [qw(bar baz biff)];
+
+Your C<arg_default_logger> method will get C<$foo> and your C<arg_levels>
+will get C<[qw(bar baz biff)]>;
=head1 FUNCTIONS
=head2 set_logger
my $logger = WarnLogger->new;
- set_logger { $logger };
+ set_logger $logger;
-Arguments: CodeRef $returning_logger
+Arguments: L</LOGGER CODEREF>
+
+C<set_logger> will just set the current logger to whatever you pass it. It
+expects a C<CodeRef>, but if you pass it something else it will wrap it in a
+C<CodeRef> for you. C<set_logger> is really meant only to be called from a
+top-level script. To avoid foot-shooting the function will warn if you call it
+more than once.
=head2 with_logger
my $logger = WarnLogger->new;
- with_logger { $logger } sub {
+ with_logger $logger => sub {
if (1 == 0) {
log_fatal { 'Non Logical Universe Detected' };
} else {
}
};
-Arguments: CodeRef $to_execute, CodeRef $returning_logger
+Arguments: L</LOGGER CODEREF>, C<CodeRef $to_execute>
+
+C<with_logger> sets the logger for the scope of the C<CodeRef> C<$to_execute>.
+As with L</set_logger>, C<with_logger> will wrap C<$returning_logger> with a
+C<CodeRef> if needed.
+
+=head2 log_$level
+
+Import Tag: C<:log>
-=head2 log_trace
+Arguments: C<CodeRef $returning_message, @args>
+
+C<log_$level> functions all work the same except that a different method
+is called on the underlying C<$logger> object. The basic pattern is:
+
+ sub log_$level (&@) {
+ if ($logger->is_$level) {
+ $logger->$level(shift->(@_));
+ }
+ @_
+ }
- log_trace { 'entered method foo with args ' join q{,}, @args };
+Note that the function returns it's arguments. This can be used in a number of
+ways, but often it's convenient just for partial inspection of passthrough data
-Arguments: CodeRef $returning_message
+ my @friends = log_trace {
+ 'friends list being generated, data from first friend: ' .
+ Dumper($_[0]->TO_JSON)
+ } generate_friend_list();
-=head2 log_debug
+If you want complete inspection of passthrough data, take a look at the
+L</Dlog_$level> functions.
- log_debug { 'entered method foo' };
+Which functions are exported depends on what was passed to L</-levels>. The
+default (no C<-levels> option passed) would export:
-Arguments: CodeRef $returning_message
+=over 2
-=head2 log_info
+=item log_trace
- log_info { 'started process foo' };
+=item log_debug
-Arguments: CodeRef $returning_message
+=item log_info
-=head2 log_warn
+=item log_warn
- log_warn { 'possible misconfiguration at line 10' };
+=item log_error
-Arguments: CodeRef $returning_message
+=item log_fatal
-=head2 log_error
+=back
- log_error { 'non-numeric user input!' };
+=head2 logS_$level
-Arguments: CodeRef $returning_message
+Import Tag: C<:log>
-=head2 log_fatal
+Arguments: C<CodeRef $returning_message, Item $arg>
- log_fatal { '1 is never equal to 0!' };
+This is really just a special case of the L</log_$level> functions. It forces
+scalar context when that is what you need. Other than that it works exactly
+same:
-Arguments: CodeRef $returning_message
+ my $friend = logS_trace {
+ 'I only have one friend: ' . Dumper($_[0]->TO_JSON)
+ } friend();
-=head1 SUGARY SYNTAX
+See also: L</DlogS_$level>.
-This package also provides:
+=head2 Dlog_$level
-L<Log::Contextual::Sugar> - provides Dlog_$level and DlogS_$level convenience
-functions
+Import Tag: C<:dlog>
+
+Arguments: C<CodeRef $returning_message, @args>
+
+All of the following six functions work the same as their L</log_$level>
+brethren, except they return what is passed into them and put the stringified
+(with L<Data::Dumper::Concise>) version of their args into C<$_>. This means
+you can do cool things like the following:
+
+ my @nicks = Dlog_debug { "names: $_" } map $_->value, $frew->names->all;
+
+and the output might look something like:
+
+ names: "fREW"
+ "fRIOUX"
+ "fROOH"
+ "fRUE"
+ "fiSMBoC"
+
+Which functions are exported depends on what was passed to L</-levels>. The
+default (no C<-levels> option passed) would export:
+
+=over 2
+
+=item Dlog_trace
+
+=item Dlog_debug
+
+=item Dlog_info
+
+=item Dlog_warn
+
+=item Dlog_error
+
+=item Dlog_fatal
+
+=back
+
+=head2 DlogS_$level
+
+Import Tag: C<:dlog>
+
+Arguments: C<CodeRef $returning_message, Item $arg>
+
+Like L</logS_$level>, these functions are a special case of L</Dlog_$level>.
+They only take a single scalar after the C<$returning_message> instead of
+slurping up (and also setting C<wantarray>) all the C<@args>
+
+ my $pals_rs = DlogS_debug { "pals resultset: $_" }
+ $schema->resultset('Pals')->search({ perlers => 1 });
+
+=head1 LOGGER CODEREF
+
+Anywhere a logger object can be passed, a coderef is accepted. This is so
+that the user can use different logger objects based on runtime information.
+The logger coderef is passed the package of the caller the caller level the
+coderef needs to use if it wants more caller information. The latter is in
+a hashref to allow for more options in the future.
+
+Here is a basic example of a logger that exploits C<caller> to reproduce the
+output of C<warn> with a logger:
+
+ my @caller_info;
+ my $var_log = Log::Contextual::SimpleLogger->new({
+ levels => [qw(trace debug info warn error fatal)],
+ coderef => sub { chomp($_[0]); warn "$_[0] at $caller_info[1] line $caller_info[2].\n" }
+ });
+ my $warn_faker = sub {
+ my ($package, $args) = @_;
+ @caller_info = caller($args->{caller_level});
+ $var_log
+ };
+ set_logger($warn_faker);
+ log_debug { 'test' };
+
+The following is an example that uses the information passed to the logger
+coderef. It sets the global logger to C<$l3>, the logger for the C<A1>
+package to C<$l1>, except the C<lol> method in C<A1> which uses the C<$l2>
+logger and lastly the logger for the C<A2> package to C<$l2>.
+
+Note that it increases the caller level as it dispatches based on where
+the caller of the log function, not the log function itself.
+
+ my $complex_dispatcher = do {
+
+ my $l1 = ...;
+ my $l2 = ...;
+ my $l3 = ...;
+
+ my %registry = (
+ -logger => $l3,
+ A1 => {
+ -logger => $l1,
+ lol => $l2,
+ },
+ A2 => { -logger => $l2 },
+ );
+
+ sub {
+ my ( $package, $info ) = @_;
+
+ my $logger = $registry{'-logger'};
+ if (my $r = $registry{$package}) {
+ $logger = $r->{'-logger'} if $r->{'-logger'};
+ my (undef, undef, undef, $sub) = caller($info->{caller_level} + 1);
+ $sub =~ s/^\Q$package\E:://g;
+ $logger = $r->{$sub} if $r->{$sub};
+ }
+ return $logger;
+ }
+ };
+
+ set_logger $complex_dispatcher;
+
+=head1 LOGGER INTERFACE
+
+Because this module is ultimately pretty looking glue (glittery?) with the
+awesome benefit of the Contextual part, users will often want to make their
+favorite logger work with it. The following are the methods that should be
+implemented in the logger:
+
+ is_trace
+ is_debug
+ is_info
+ is_warn
+ is_error
+ is_fatal
+ trace
+ debug
+ info
+ warn
+ error
+ fatal
+
+The first six merely need to return true if that level is enabled. The latter
+six take the results of whatever the user returned from their coderef and log
+them. For a basic example see L<Log::Contextual::SimpleLogger>.
+
+=head1 LOG ROUTING
+
+In between the loggers and the log functions is a log router that is responsible for
+finding a logger to handle the log event and passing the log information to the
+logger. This relationship is described in the documentation for C<Log::Contextual::Role::Router>.
+
+C<Log::Contextual> and packages that extend it will by default share a router singleton that
+implements the with_logger() and set_logger() functions and also respects the -logger,
+-package_logger, and -default_logger import options with their associated default value
+functions. The router singleton is available as the return value of the router() function. Users
+of Log::Contextual may overload router() to return instances of custom log routers that
+could for example work with loggers that use a different interface.
