"The easy way is always mined. The important things are always simple. The simple things are always hard." -- Some of Murphy's Laws of Combat This is a short set of guidelines for those contributing ExtUtils::MakeMaker. It's not an iron-clad set of rules, but just things which make life easier when reading and integrating a patch. Reporting bugs - Often the only information we have for fixing a bug is contained in your report. So... - Please report your bugs via http://rt.cpan.org or https://github.com/Perl-Toolchain-Gang/ExtUtils-MakeMaker/issues or by mailing to makemaker@perl.org. RT or GitHub are preferred. - Please report your bug immediately upon encountering it. Do not wait until you have a patch to fix the bug. Patches are good, but not at the expense of timely bug reports. - Please be as verbose as possible. Include the complete output of your 'make test' or even 'make test TEST_VERBOSE=1' and a copy of the generated Makefile. Err on the side of verbosity. The more data we have to work with, the faster we can diagnose the problem. - If you find an undocumented feature, or if a feature has changed/been added which causes a problem, report it. Do not assume it was done deliberately. Even if it was done deliberately, we still want to hear if it caused problems. - If you're testing MakeMaker against a development version of Perl, please also check it against the latest stable version. This makes it easier to figure out if it's MakeMaker or Perl at fault. Pull Request - If you wrote a patch already, please Pull Request on GitHub. - Pull Request against the latest development snapshot from GitHub repository are preferred. - Pull Request against the latest CPAN version are ok, too. Code formatting - No literal tabs (except where necessary inside Makefile code, obviously). - 4 character indentation. - this_style is preferred instead of studlyCaps. - Private subroutine names (ie. those used only in the same package they're declared in) should start with an underscore (_sekret_method). - Protected subroutines (ie. ones intended to be used by other modules in ExtUtils::*) should be named normally (no leading underscore) but documented as protected (see Documentation below). - Do not use indirect object syntax (ie. new Foo::Bar (@args)) - make variables use dollar signs like Perl scalars. This causes problems when you have to mix them both in a string. If you find yourself backwacking lots of dollar signs because you have one interpolated perl variable, like this: return <<EOT; subdirs :: \$(NOECHO)cd $subdir && \$(MAKE) -f \$(FIRST_MAKEFILE) all \$(PASTHRU) EOT or are switching quoting contexts: return q{ subdirs :: $(NOECHO)cd }.$subdir.q{ && $(MAKE) -f $(FIRST_MAKEFILE) all $(PASTHRU) }; consider using sprintf instead. return sprintf <<'EOT', $subdir; subdirs :: $(NOECHO)cd %s && $(MAKE) -f $(FIRST_MAKEFILE) all $(PASTHRU) EOT Refactoring and Cleanup - MakeMaker is a mess. We like patches which clean things up. Backwards Compatibility - MakeMaker must be backwards compatible to 5.6.2. Avoid any obvious 5.8-isms. - MakeMaker should avoid having module dependencies. But if new code need depends the modules absolutely, it will bundle the modules. See Makefile.PL of ExtUtils::MakeMaker for detail. Cross-Platform Compatibility - MakeMaker must work on all architectures Perl works on (see perlport.pod). This means all Unixen (including Cygwin and MacOS X), Windows, and VMS. - Use the available macros rather than shell commands $(MV), $(CP), $(TOUCH), etc... - MakeMaker must work on many makes. GNU, BSD, Solaris, nmake, dmake, MMS and MMK to name the most common. Keep your make code as simple as possible. - Avoid special make variables (even $@). - Format targets as "target : dependency", the spacing is important. - Use $(NOECHO) instead of @. - Use - to tell make to ignore the exit code of a command. (Unfortunately, some make variants don't honor an $(IGNORE) macro). - Always put a space between $(NOECHO) and the command. - Always put a space between - (ignore) and the command. - Always put $(NOECHO) and - together, no space between them. # Right -$(NOECHO) command $(NOECHO) command - command - Often when you patch ExtUtils::MM_Unix, similar patches must be done to the other MM_* modules. If you can, please do this extra work otherwise I have to. If you can't, that's ok. We can help. - If possible, please test your patch on two Very Different architectures. Unix, Windows and VMS being Very Different. Note: Cygwin and OS X are Unixen for our purposes. - If nothing else, at least try it on two different Unixen machines (ie. Linux and OS X). - If you find yourself writing "do_this if $^O eq 'That'" (ie. checks on the OS type) perhaps your code belongs in one of the non-Unix MM_* modules (ie. MM_Win32, MM_VMS, etc...). If one does not exist, consider creating one. It's ok to have an MM_* module with only one method. - Some shells have very small buffers. This means command lines must be as small as possible. If your command is just too long, consider making it an ExtUtils::Command::MM function. If your command might receive many arguments (such as pod2man or pm_to_blib) consider using split_command() to split it into several, shorter calls. - Most shells quote differently. If you need to put a perl one-liner in the Makefile, please use oneliner() to generate it. Tests - Tests would be nice, but I'm not going to pretend testing MakeMaker is easy. If nothing else, let us know how you tested your patch by hand. It does really help everyone if you can improve tests, though! - Travis CI (https://travis-ci.org) is good sources of testing machines of many perl versions. Accounts are free. Documentation - Documentation would be nice. - If the new feature/method is private, please document it with POD wrapped in "=begin/end private" tags. That way it will be documented, but won't be displayed (future versions of perldoc may have options to display). =begin private =head3 _foo_bar $mm->_foo_bar Blah blah blah =end private =cut sub _foo_bar { ... - If you're overriding a method, document that it's an override and *why* it's being overridden. Don't repeat the original documentation.
