This is only a DRAFT!

Guidelines for packaging Drupal 7 modules and themes

Different Kinds of Packages

  • Modules: Modules extend and customize Drupal functionality.
  • Themes: Themes allow users to change the look and feel of their Drupal site.

Naming Scheme

Every package MUST be named drupal7-<drupal_machine_name>. Drupal itself enforces unique machine names for each of its' projects and there is a single namespace for all modules, themes, and distributions/profiles. The <drupal_machine_name> MUST match the drupal.org project name (i.e. drupal.org/project/<drupal_machine_name>).

File Placement

  • Modules: A module package MUST be placed in the %drupal7_modules directory (base "modules/" directory)
  • Themes: A theme package MUST be placed in the %drupal7_themes directory (base "themes/" directory)
  • Libraries: A library package MUST be placed in the %drupal7_libraries directory (base "libraries/" directory)

Requires and Provides

  • Every package SHOULD require "drupal7(<drupal_machine_name>)" virtual resources instead of "drupal7-<drupal_machine_name>" packages.
  • Every package MUST include the following in its' spec:
    • The drupal7-rpmbuild package automatically requires drupal7(core) and scans files for provides (from *.info files) and automatically adds them to the package during build time as "drupal7(<drupal_machine_name>)" virtual resources. Hidden projects are ignored. The use of virtual provides and requires helps alleviate the confusion of sub-modules and which modules actually provide those sub-modules. They also help simplify spec files. 
      BuildRequires: drupal7-rpmbuild >= 7.22-5
    • For compatibility with RPM < 4.9 (i.e. EPEL 5/6): 
      %{?drupal7_find_provides_and_requires}
  • Every package MUST NOT:
    • explicitly require "drupal7" or "drupal7(core)" (unless a specific core version is required) because drupal7-rpmbuild auro-requires "drupal7(core)"
    • explicitly provide "drupal7(<drupal_machine_name>)" virtual resources because drupal7-rpmbuild auto-provides these

Other Packages

See PHP packaging guidelines.

PHP Extensions

See PHP packaging guidelines.

To get a list of required PHP extensions, use PHP_CompatInfo (phpci): 

phpci print --recursive --report=extension unpacked_package_source_directory

To install PHP_CompatInfo (phpci), run "yum install php-bartlett-PHP-CompatInfo".

Requiring a Minimum PHP Version

See PHP packaging guidelines but note that this should not normally be required by most packages (see [1]).

Important.png
This needs to be added to the drupal7-rpmbuild package so it is automatic.

Macros and Scriptlets

Macros provided by the drupal7-rpmbuild package:

Macro Value Description
%drupal7 %{_datadir}/drupal7 Drupal 7 base directory
%drupal7_modules %{drupal7}/modules Drupal 7 modules directory
%drupal7_themes %{drupal7}/themes Drupal 7 themes directory
%drupal7_libraries %{_sysconfdir}/drupal7/all/libraries Drupal 7 libraries directory
%drupal7_find_provides_and_requires Fedora:

%{nil}

EPEL 5/6:
%{expand: \
%global _use_internal_dependency_generator 0
%global __find_provides %{_rpmconfigdir}/drupal7.prov %{version}
%global __find_requires %{_rpmconfigdir}/drupal7.req
}

Fedora:

No-op macro to allow spec compatibility with RPM < 4.9 (no fileattrs)

EPEL 5/6:
Macro to allow spec compatibility with RPM < 4.9 (no fileattrs)

Additional Hints

  • Every module package SHOULD list the Drupal modules it provides in its' description: 
     This package provides the following Drupal module(s):
 * %{module_name}

    For example, the drupal7-domain package contains the following in its' description: 

    This package provides the following Drupal modules:
* %{module_name}
* %{module_name}_alias
* %{module_name}_conf
* %{module_name}_content
* %{module_name}_nav
* %{module_name}_settings
* %{module_name}_source
* %{module_name}_strict
* %{module_name}_test
* %{module_name}_theme

Templates

RPM README

After installation, you must enable this module from the Drupal administration
page.

If upgrading this module separately from the core Drupal package, be sure to
run the http://hostname/drupal7/upgrade.php script after this RPM is upgraded.
