Icon+Unicon/Analysis of UnimplementedTasks

Analysis of Tasks Icon/Unicon Unimplemented

The following summarizes tasks that are not completed for Icon/Unicon on Rosetta Code. Note: This is not dynamically compiled and tasks may have been completed.

My intent is twofold.

• Encourage more contribution from other by more clearly identifying areas where they can help.
• Encourage a general discussion (beyond Icon/Unicon) of task classification/sub-classification. (I know that SML may have a huge impact on this once an approach is found).

While I realize that some of the tasks could easily fall into multiple categories, I've tried to pick a (near) best fit.

Also, I've annotated a (bare) handful of tasks.

Some quick links:

• Unicon main page
• Unicon Talk/Discussion page Lots of notes about things to do, help wanted, ideas, and guidance on formatting and markup
• Unimplementable tasks Tasks that cannot be implemented in the language
• Tasks requiring attention Tasks that could be improved
• Icon+Unicon/Intro Introduction to Icon and Unicon
• Most Linked Categories shows how many pages various languages (and other categories) have.

The official up to date list of tasks not yet implemented in Unicon

This list is dynamically generated by the RC Wiki:

Analysis of Programming Categories on Rosetta

The following list was manually gleaned from the list of categories (special pages) and annotated. It provides another way of looking at the program groupings. There are a number of discussions on the Rosetta Code:Village Pump and in individual tasks about categorization and how to approach it. Use of SMW may change the way in which this is done.

This may also prove useful for editors looking to cleanup categories (e.g. typos).
