This adds the $projects_list_group_categories option which, if enabled,
will result in grouping projects by category on the project list page.
The category is specified for each project by the $GIT_DIR/category file
or the 'category' variable in its configuration file. By default, projects
are put in the $project_list_default_category category.

Note:
- Categories are always sorted alphabetically, with projects in
  each category sorted according to the globally selected $order.

I am not sure if always sorting the categories alphabetically is a severe
enough restriction, but if it was, you can use @project_list_categories
array that disables the feature when empty and otherwise enumerates the
categories in order.  Just an idle thought.

Well, this way of sorting, i.e. keeping order of categories constant,
and changing order _within_ categories has the advantage that changing
order (the column we sort by) doesn't change page layout, i.e. in this
case doesn't change categories layout.


It means that if we had:

  project1
  project2
  [category A]
  A/pr1
  A/pr2
  [category B]
  B/pr1
  B/pr2
  B/pr3

when sorting by project name, we will have similarly looking

  project2
  project1
  [category A]
  A/pr1
  A/pr2
  [category B]
  B/pr3
  B/pr1
  B/pr2

for example if we order by age (not shown here)

- When displaying a subset of all the projects, only the categories with
  projects in the chosen subset are displayed.

Could you clarify this bit?

It is not very clear to me how this subset selection happens.  As far as I
can see, the user does not choose the category to view, but lets the usual
page limiting to decide at which project to start and stop placing on the
page, and only show the ones in the same category as the one that happened
to be the first on the page.

Currently the only selection is by tag, but lets assume that we have
some page length limit and only first N projects (first N in given sort
order) are shown.

If we have selection by tag, only those categories that have at least
one project tagged with selected tag, and only projects with given tag
would be shown. If we have page limit on projects list page, and we
sort for example by age, then only categories with freshest projects
will be shown.

At least it is how I understand it...

 

While I think both the introduction of "git_get_project_config_or_file"

Errr... I think it is git_get_file_or_project_config ;-))))

which is a generalized interface usable between description and the new
feature and the refactoring of project_list_body into a seprate function
"print_project_rows" is a good idea, the patch would have been much easier
to read if these preparatory refactoring steps (without any new feature)
were done as a separate patch followed by the main patch to introduce the
new feature.

 
I agree, especially the second part, as adding print_project_rows patch
looks harder than it actually is.
