NAME

HACKING.pod - contributing to TAP::Harness

ABOUT

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

If you are looking for more information on how to use TAP::Harness, you probably want <http://testanything.org/wiki/index.php/TAP::Parser_Cookbook> instead.

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.

Formatting

perltidy

The project comes with a ".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:

•

vim

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

•

emacs

For emacs, you can use this snippet from Sam Tregar (<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)
 
 

Tests and Coverage

Writing for Compatibility

...

Documentation

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

Pod Commands

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

"=head1 SECTION"

Sections begin with an "=head1" command and are all-caps.

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

"=head2 method"

The "=head2" command documents a method. The name of the method should have no adornment (e.g. don't C>method> or C>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 parameter"

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

Pod Formatting Codes

L<Some::Module>

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

VERSION

The version numbers are updated by Perl::Version.

DEVELOPER DOCS/NOTES

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

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 ...
 
 

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
 
 

deprecated

   =for deprecated
     removed in 0.09, kill by ~0.25
