Stage File Proxy is a general solution for getting production files on a development server on demand. It saves you time and disk space by sending requests to your development environment's files directory to the production environment and making a copy of the production file in your development site. You should not need to enable this module in production.
Provides a database table containing indexes to entities of any type. This module doesn't do anything on its own and should only be installed if another module depends on it.
This module provides more features for developers and themers when they debugging drupal.
Writing code on your website using GeSHi? Maybe you'd like that code to be compiled automatically for you?
The Compile GeSHi Node module offers an interface for this purpose. It is a bit of manual setup, but you're a programmer, so it shouldn't scare you a bit. Get ready to compile your code without having to run make in your command line and copy/paste the code from your text files to your browser!
Note: The d7 version of this module should no longer be necessary when using more recent versions of Features module. If you feel this is incorrect, please open an issue.
This module is useful for feature development using the Features module. Occasionally the Features module auto detects components that you do not want exported to features. You can use this module to remove those auto-detected components from any and all features you choose. The Features Plumber UI module adds checkboxes to the feature create form, and unchecking these detected components will cause them to be removed from the actual generated export.
Selector lets you select a Features component to be exported to a feature right in the place in Drupal UI where a settings element for it resides. It provides a widget in that place near the element itself, which is giving you also information about the particular component and its presence (status) in available features.
At the moment it provides support for all core modules and these modules in addition:
This module integrates Node.js with Drupal.
It provides an API that other modules can use to add realtime capabilities to Drupal, such as push notifications or chat. The module relies on a Node.js server application that maintains an open connection with the visitor's browser to enable instant communication. In order to use this module, you will need to install the Node.js application on a server.
Drush script to check how broken a drupal installation is. Extra points for having contrib modules in the modules/ folder, for having php code in blocks and nodes. May also check if the core has been hacked for convenience (although http://drupal.org/project/hacked does that just fine).
This module brings various improvements to the core Taxonomy module.
