Option to display tag cloud in descending order

[Adriana]

How can I modify tractags.macros to display tag cloud in descending order, starting with the most used tags? I don't understantand what is the current sort order.

It is strange, because on my Trac (running TagsPlugin 0.6) they are mostly displayed alphabetically, with the exception of the entries at the end,

I don't mean alphabetical order. I would like to see the most used tags at the beginning of the cloud (tags ordered by their occurrence).

I was just trying to determine what is the current sort order. Given that, maybe we can add an option to the macro ... however, the current sort order doesn't make much sense to me.

I need tags ordered by their occurrence because I'm working to create a plugin that suggests tags. :-) The first step of implementation should be suggest the most used tags (eg. top ten).

[Steffen Hoffmann]

I see your point.

There is an internal object, that could be used for sorting on number of occurrences. However, please understand, that right now performance (#4503) is a much higher priority than new features, so this is still getting postponed.

Implementation of this feature request will be easier now with new Counter objects, still it should be considered for next release's development.

Since [13427] we have tractags.api.TagSystem.get_all_tags(), so it is part of current stable tractags-0.7 as well.

This method returns a Counter object. Use its .most_common(n) method to extract the <n> top-most tags as a list of tuples with their number of occurrence in descending order. This will likely give you all you need for your plugin application.

I'm undecided how to proceed here. The request regarding API usage for other Trac plugins is clearly resolved IMHO.

Do we need more options regarding the sorting order? For the macro and web-UI. Maybe, but if any, I suggest extending cloud_caseless_sort into something more general, like a cloud_sort list option, and make desc another list entry next to caseless. Thoughts?
