Compare Module across Configurations


Compare Module acreoss Configuration is intended for very quick comparison of your module against another configuration, usually stream against previous version (baseline)



) )


This extension provides a convenient solution for quickly comparing module configurations in IBM DOORS Next Generation. 
With this extension, users can effortlessly compare the current stream against a previous version or baseline with just one click, significantly reducing the time and effort required to perform this task. Additionally, the comparison is presented in a user-friendly format that allows for easy identification of differences and similarities between the two configurations. Overall, this extension improves the efficiency and accuracy of module comparisons in DNG.
Users to initiate a Module comparison in the UI with a single click, thereby streamlining the process which would otherwise necessitate nine separate clicks. The comparison will display the current UI's rich text in a side-by-side format.

Use Cases and Features

Based on the functionalities and use cases that this extension is helping you with, we kept the user interface as simple as possible. In the current version of the widget you can find: 

  • Widget information section - section with version, short description and other informations about the extension
  • Dropdown for selection of Baseline - 
  • Main Button - after all necessary selections are made this button must be pressed to start an extension

The Module Comparator (CMC) extension is designed to address the problem of time-consuming and inefficient comparison of modules in IBM Rational DNG. With this extension, users can compare their current module against the same module in other configurations, with the default configuration being the last baseline of the current stream. The extension provides a quick and easy way to identify which artifacts have changed, with blue indicating changes, yellow indicating new artifacts, and gray with red strike-through indicating deleted artifacts.

Additionally, many users who have transitioned from DOORS Classic to DNG have reported missing the blue and yellow bars that were used to indicate changes in the former tool. This extension restores this feature to DNG users, allowing for a more familiar and intuitive comparison experience. Moreover, the extension eliminates the need for multiple clicks to access information on the last baseline, allowing for a more streamlined and efficient comparison process.

The Compare Module across Configuration widget has the following features:

  • Show only changes - The extension has a default setting to display only the modified artifacts, along with their heading parents. This feature ensures that even significant modules with minimal changes can be analyzed for modifications. To view the complete module explorer tree, users may click on the 'Expand' button.
  • Expand Button - The Expand button (+) enables users to expand the entire module with all the changes made. As some modules can be very large in size, sections with no changes are shown but collapsed by default. Although users can expand them manually, it is not necessary to do so when there are no changes in the chapter.
  • Collapse Button - The Collapse Button (-) enables the display of only the sections of the module where changes have been made. Additionally, it displays the unchanged Parent Headings to facilitate the identification of the specific areas where modifications have been performed.
  • Jump to Artifact  - The CMC Widget empowers users to navigate with ease to specific artifacts within the module. Simply clicking on an artifact in the widget will promptly highlight the relevant section within the module.
  • Full Compare - The "Full Compare" function provides users with a streamlined process to open the DNG native comparison of the configurations. By clicking this button, users can avoid the 8-10 clicks typically required to access this comparison. In addition to displaying textual changes, the Full Compare screen provides the added benefit of showing changed links. It should be noted that the CMC widget only compares textual changes, as changes to links on artifacts do not alter the "Modified On" attribute.
  • Rich Text Direct Compare - The CMC widget provides the option to directly compare the changed primary text within the widget itself, without the need to initiate a full compare. If there are no changes displayed, it indicates that attributes other than the primary text have been modified in the artifact.

Softacus has developed an extensionwhich is facilitate rapid comparison of a user's module against an alternative configuration, typically a stream versus a prior version, or baseline (all of which within your Mini Dashboard only by 1 click).

Preconditions and Restrictions

As with any software solution, this extension has certain limitations that users should be aware of. These limitations include:

  • The script cannot be executed outside the module
  • The links in the module are not color coded in the Extension and are compared only "Full Compare" view. The reason for this is the fact that Modification of links tags and comments does not affect "Last Modified Date" which we use for performance reasons
  • Comparison does not work for tags and comments
