Module Reference List

Modules I Use

Development

Devel A suite of modules containing tools for module developers and themers.

Field Modules

Date This package contains both a flexible date/time field type Date field and a Date API that other modules can use.
Link URL field type for content.
RSS field formatters Provides field formatters for the node RSS view mode. Notably, it adds RSS file enclosures back to Drupal 7.
Text Formatter This module provides a field formatter to render values in text, long text, number, list, and taxonomy reference fields as HTML or comma-separated lists.

Mapping

Geocoder

This module will geocode just about anything you throw at it including addresses, GPX files, geo-tagged images, and KML files.

Security Modules

Security Review The Security Review module automatically audits many of the easy-to-make mistakes that render your site insecure.

Site Building

Global Redirect Global Redirect adds some sanity around providing consistant path aliases. It's usually recommended for SEO purposes but worth adding for a consistant path presentation.
Login Destination The Login Destination module allows you to customize the destination that a user is redirected to after logging in, registering to the site (7.x), using a one-time login link or logging out (7.x).
Menu Position This module allows for the creation of rules that will dynamically add the current page into the menu system at the requested spots. This makes thinks like active menu classes work correctly on individual pieces of content.
Nodequeue The Nodequeue module allows users to collect nodes in an arbitrarily ordered list. This list can be used with Views to provide featured content or lists on a page or in blocks.

Pathauto

Automatically generates URL/path aliases for various kinds of content (nodes, taxonomy terms, users) without requiring the user to manually specify the path alias.
Token Tokens are small bits of text that can be placed into larger documents via simple placeholders, like %site-name or [user]. The Token module provides a central API for modules to use these tokens, and expose their own token values.
Views Views is block and page building tool that allows the easy construction of list and report style pages. There are a number of companion modules that extend this functionality to displaying slide shows and performing bulk operations.

Theming

Skinr Skinr's main purpose is to allow the theme to define a set of reusable and modular CSS styles, and to make those styles available in Drupal's UI.

User Interface Modules

Administration Menu Provides a theme-independent tool bar style pull-down menu for the site administration functions. Drupal 7 has it's own version but I like this one better.
Wysiwyg Allows to use client-side editors to edit content. It simplifies the installation and integration of the editor of your choice.
