Dreditor (short for "Drupal editor" and pronounced /'dɹɛdɪtə/) started as a simple idea for a (greasemonkey) browser user script to help module maintainers, Drupal core maintainers, and developers in general to review patches on

Dreditor provides multiple applications/helpers for and implements a concept of applications/namespaces/modules. The user script can re-use all available data on as well as common Drupal development practices.

APIs and helpers

Dreditor additionally contains the following noteworthy components and sub-systems:

jQuery.debug() Allows to debug and inspect arbitrary data/variables in Firebug's console, but also to access them again in the global window object (optionally using a named identifier, e.g. window.debug.myValue). Chainable via jQuery. Especially useful for re-accessing and debugging selected data via Firebug's console. (now also available via admin_devel module)

jQuery Form API Initial stab at building, processing, and rendering jQuery-enabled forms in a JS-only environment. Supports multiple form submit handlers. To be continued.
