=head1 NAME
|
||
|
||
diagnostics, splain - produce verbose warning diagnostics
|
||
|
||
=head1 SYNOPSIS
|
||
|
||
Using the C<diagnostics> pragma:
|
||
|
||
use diagnostics;
|
||
use diagnostics -verbose;
|
||
|
||
enable diagnostics;
|
||
disable diagnostics;
|
||
|
||
Using the C<splain> standalone filter program:
|
||
|
||
perl program 2>diag.out
|
||
splain [-v] [-p] diag.out
|
||
|
||
Using diagnostics to get stack traces from a misbehaving script:
|
||
|
||
perl -Mdiagnostics=-traceonly my_script.pl
|
||
|
||
=head1 DESCRIPTION
|
||
|
||
=head2 The C<diagnostics> Pragma
|
||
|
||
This module extends the terse diagnostics normally emitted by both the
|
||
perl compiler and the perl interpreter (from running perl with a -w
|
||
switch or C<use warnings>), augmenting them with the more
|
||
explicative and endearing descriptions found in L<perldiag>. Like the
|
||
other pragmata, it affects the compilation phase of your program rather
|
||
than merely the execution phase.
|
||
|
||
To use in your program as a pragma, merely invoke
|
||
|
||
use diagnostics;
|
||
|
||
at the start (or near the start) of your program. (Note
|
||
that this I<does> enable perl's B<-w> flag.) Your whole
|
||
compilation will then be subject(ed :-) to the enhanced diagnostics.
|
||
These still go out B<STDERR>.
|
||
|
||
Due to the interaction between runtime and compiletime issues,
|
||
and because it's probably not a very good idea anyway,
|
||
you may not use C<no diagnostics> to turn them off at compiletime.
|
||
However, you may control their behaviour at runtime using the
|
||
disable() and enable() methods to turn them off and on respectively.
|
||
|
||
The B<-verbose> flag first prints out the L<perldiag> introduction before
|
||
any other diagnostics. The $diagnostics::PRETTY variable can generate nicer
|
||
escape sequences for pagers.
|
||
|
||
Warnings dispatched from perl itself (or more accurately, those that match
|
||
descriptions found in L<perldiag>) are only displayed once (no duplicate
|
||
descriptions). User code generated warnings a la warn() are unaffected,
|
||
allowing duplicate user messages to be displayed.
|
||
|
||
This module also adds a stack trace to the error message when perl dies.
|
||
This is useful for pinpointing what
|
||
caused the death. The B<-traceonly> (or
|
||
just B<-t>) flag turns off the explanations of warning messages leaving just
|
||
the stack traces. So if your script is dieing, run it again with
|
||
|
||
perl -Mdiagnostics=-traceonly my_bad_script
|
||
|
||
to see the call stack at the time of death. By supplying the B<-warntrace>
|
||
(or just B<-w>) flag, any warnings emitted will also come with a stack
|
||
trace.
|
||
|
||
=head2 The I<splain> Program
|
||
|
||
Another program, I<splain> is actually nothing
|
||
more than a link to the (executable) F<diagnostics.pm> module, as well as
|
||
a link to the F<diagnostics.pod> documentation. The B<-v> flag is like
|
||
the C<use diagnostics -verbose> directive.
|
||
The B<-p> flag is like the
|
||
$diagnostics::PRETTY variable. Since you're post-processing with
|
||
I<splain>, there's no sense in being able to enable() or disable() processing.
|
||
|
||
Output from I<splain> is directed to B<STDOUT>, unlike the pragma.
|
||
|
||
=head1 EXAMPLES
|
||
|
||
The following file is certain to trigger a few errors at both
|
||
runtime and compiletime:
|
||
|
||
use diagnostics;
|
||
print NOWHERE "nothing\n";
|
||
print STDERR "\n\tThis message should be unadorned.\n";
|
||
warn "\tThis is a user warning";
|
||
print "\nDIAGNOSTIC TESTER: Please enter a <CR> here: ";
|
||
my $a, $b = scalar <STDIN>;
|
||
print "\n";
|
||
print $x/$y;
|
||
|
||
If you prefer to run your program first and look at its problem
|
||
afterwards, do this:
|
||
|
||
perl -w test.pl 2>test.out
|
||
./splain < test.out
|
||
|
||
Note that this is not in general possible in shells of more dubious heritage,
|
||
as the theoretical
|
||
|
||
(perl -w test.pl >/dev/tty) >& test.out
|
||
./splain < test.out
|
||
|
||
Because you just moved the existing B<stdout> to somewhere else.
|
||
|
||
If you don't want to modify your source code, but still have on-the-fly
|
||
warnings, do this:
|
||
|
||
exec 3>&1; perl -w test.pl 2>&1 1>&3 3>&- | splain 1>&2 3>&-
|
||
|
||
Nifty, eh?
|
||
|
||
If you want to control warnings on the fly, do something like this.
|
||
Make sure you do the C<use> first, or you won't be able to get
|
||
at the enable() or disable() methods.
|
||
|
||
use diagnostics; # checks entire compilation phase
|
||
print "\ntime for 1st bogus diags: SQUAWKINGS\n";
|
||
print BOGUS1 'nada';
|
||
print "done with 1st bogus\n";
|
||
|
||
disable diagnostics; # only turns off runtime warnings
|
||
print "\ntime for 2nd bogus: (squelched)\n";
|
||
print BOGUS2 'nada';
|
||
print "done with 2nd bogus\n";
|
||
|
||
enable diagnostics; # turns back on runtime warnings
|
||
print "\ntime for 3rd bogus: SQUAWKINGS\n";
|
||
print BOGUS3 'nada';
|
||
print "done with 3rd bogus\n";
|
||
|
||
disable diagnostics;
|
||
print "\ntime for 4th bogus: (squelched)\n";
|
||
print BOGUS4 'nada';
|
||
print "done with 4th bogus\n";
|
||
|
||
=head1 INTERNALS
|
||
|
||
Diagnostic messages derive from the F<perldiag.pod> file when available at
|
||
runtime. Otherwise, they may be embedded in the file itself when the
|
||
splain package is built. See the F<Makefile> for details.
|
||
|
||
If an extant $SIG{__WARN__} handler is discovered, it will continue
|
||
to be honored, but only after the diagnostics::splainthis() function
|
||
(the module's $SIG{__WARN__} interceptor) has had its way with your
|
||
warnings.
|
||
|
||
There is a $diagnostics::DEBUG variable you may set if you're desperately
|
||
curious what sorts of things are being intercepted.
|
||
|
||
BEGIN { $diagnostics::DEBUG = 1 }
|
||
|
||
|
||
=head1 BUGS
|
||
|
||
Not being able to say "no diagnostics" is annoying, but may not be
|
||
insurmountable.
|
||
|
||
The C<-pretty> directive is called too late to affect matters.
|
||
You have to do this instead, and I<before> you load the module.
|
||
|
||
BEGIN { $diagnostics::PRETTY = 1 }
|
||
|
||
I could start up faster by delaying compilation until it should be
|
||
needed, but this gets a "panic: top_level" when using the pragma form
|
||
in Perl 5.001e.
|
||
|
||
While it's true that this documentation is somewhat subserious, if you use
|
||
a program named I<splain>, you should expect a bit of whimsy.
