=head1 NAME

HACKING.pod - contributing to TAP::Harness

=head1 ABOUT

This is the guide for TAP::Harness internals contributors (developers,
testers, documenters.)

If you are looking for more information on how to I<use> TAP::Harness,
you probably want the L<TAP::Harness::Cookbook> instead.

=head1 Getting Started

See the resources section in META.yml (or Build.PL) for links to the
project mailing list, bug tracker, svn repository, etc.

For best results, read the rest of this file, check RT for bugs which
scratch your itch, join the mailing list, etc.

=head1 Formatting

=head2 perltidy

The project comes with a C<.perltidyrc>, which perltidy will
automatically use if the project root is your working directory.  This
is setup by default to read and write the perl code on a pipe.  To
configure your editor:

=over 4

=item * vim

In C<.vimrc>, you can add the following lines:

 nnoremap <Leader>pt :%!perltidy -q<cr> " only work in 'normal' mode
 vnoremap <Leader>pt :!perltidy -q<cr>  " only work in 'visual' mode

In other words, if your C<Leader> is a backslash, you can type C<\pt> to
reformat the file using the C<.perltidyrc>.  If you are in visual mode
(selecting lines with shift-v), then only the code you have currently have
selected will be reformattted.

=item * emacs

For emacs, you can use this snippet from Sam Tregar
(L<http://use.perl.org/~samtregar/journal/30185>):

 (defun perltidy-region ()
    "Run perltidy on the current region."
    (interactive)
    (save-excursion
      (shell-command-on-region (point) (mark) "perltidy -q" nil t)
      (cperl-mode)))

 (defun perltidy-all ()
    "Run perltidy on the current region."
    (interactive)
    (let ((p (point)))
      (save-excursion
        (shell-command-on-region (point-min) (point-max) "perltidy -q" nil t)
        )
      (goto-char p)
      (cperl-mode)))

 (global-set-key "\M-t" `perltidy-region)
 (global-set-key "\M-T" `perltidy-all)

=head1 Tests and Coverage

=for eric_not_it
  TODO link to a good guide on writing tests for TAP::Parser

=head1 Writing for Compatibility

...

=for eric_not_it
  TODO explain no bundling, PERL_CORE, etc

=head1 Documentation

The end-user and API documentation is all in the 'lib/' directory.  In
.pm files, the pod is "inline" to the code.  See L<perlpod> for more
about pod.

=head2 Pod Commands

For compatibility's sake, we do not use the =head3 and =head4 commands.

=over

=item C<=head1 SECTION>

Sections begin with an C<=head1> command and are all-caps.

=for eric_not_it
  I guess... Mixed case messes with various pod hacking tools.

  NAME
  VERSION
  SYNOPSIS
  CONSTRUCTOR
  METHODS
  CLASS METHODS
  SOME OTHER SORT OF METHODS
  SEE ALSO

=item C<=head2 method>

=for eric_not_it
  The following is how I would do it, but opposite of what we have.

The C<=head2> command documents a method.  The name of the method should have no adornment (e.g. don't CE<gt>method> or CE<gt>method($list, $of, $params)>.)

These sections should begin with a short description of what the method
does, followed by one or more examples of usage.  If needed, elaborate
on the subtleties of the parameters and context after (and/or between)
the example(s).

  =head2 this_method

  This method does some blah blah blah.

    my @answer = $thing->this_method(@arguments);

  =head2 that_thing

  Returns true if the thing is true.

    if($thing->that_thing) {
      ...
    }

=item C<=item parameter>

Use C<=item> commands for method arguments and parameters (and etc.)  In
most html pod formatters, these I<do not> get added to the
table-of-contents at the top of the page.

=back

=head2 Pod Formatting Codes

=over

=item LE<lt>Some::Module>

Be careful of the wording of C<LE<lt>Some::ModuleE<gt>>.  Older pod
formatters would render this as "the Some::Module manpage", so it is
best to either word your links as "C<(see E<lt>Some::ModuleE<gt> for
details.)>" or use the "explicit rendering" form of
"C<E<lt>Some::Module|Some::ModuleE<gt>>".

=back

=head2 VERSION

The version numbers are updated by L<Perl::Version>.

=head2 DEVELOPER DOCS/NOTES

The following "formats" are used with C<=begin>/C<=end> and C<=for>
commands for pod which is not part of the public end-user/API
documentation.

=over

=item note

Use this if you are uncertain about a change to some pod or think it
needs work.

  =head2 some_method

    ...

  =for note
    This is either falsely documented or a bug -- see ...

=item developer

  =begin developer

  Long-winded explanation of why some code is the way it is or various
  other subtleties which might incite head-scratching and WTF'ing.

  =end developer

=item deprecated

  =for deprecated
    removed in 0.09, kill by ~0.25

=for developer
... or whatever.  I'm just making stuff up here.  If any of this is
wrong, please correct it.  To the extent that there is an "official
policy", it should be written down. --Eric
