# Rosetta Code/Count examples/Full list

Full output for the Rosetta Code/Count examples#Raku task. Updated periodically.

This is something of a experiment. The languages have their completed task entries marked with a circled digit in the table so you can sort on the language to see which tasks have been done. Hold down control and click on several columns to do secondary, tertiary, etc. sorts.

Languages that omit a certain task have an uppercase O filled in for that task.

Ideally it would be nice to be able to generate the table on demand for any language but it is fairly intensive to generate. Once a week is ok, on demand would be unsustainable.

More than about 10 languages per page gets unwieldy and difficult to navigate. Generate reports for the top N languages in groups of 10. (N == 40 for now.)

See Rosetta_Code/Rank_languages_by_popularity/Full_list for a full language/task completion table.
