I probably should have spotted this before, but "section" isn't being
properly escaped after this patch.  This needs to be:

	html("<a href='");
	html_attr(section);
	html("'>");
	html_txt(section);
	html("</a>");

(although the first and last strings could be combined with the
surrounding statements).

[PATCH 2/2] ui-repolist: Allow sections to be collapsible

[andy.doan]

The index page can be difficult to navigate for really large git
servers. This change allows a configuration like:

 section-collapse=people
 section-collapse=tests

And an index page would only display the "people" and "tests" section
headers entries (not their repos) with a hyperlink that can be used to
drill down into each section.

Additionally the boolean logic around displaying sections in
ui-repolist.c was simplified to eliminate an impossible condition.

[PATCHv3 0/2] Collapsible Section Support

[andy.doan]

This series adds hyperlinks to sections and allows them to be collapsed.
A running version of cgit with this change can be seen here:

  https://git-ap.linaro.org/cgit/

Changes since v2:
 - use proper html escaping for section hyperlinks.

[PATCHv2 0/2] Collapsible Section Support

[Jason]

Hey Andy,

One issue with this is -- isn't this the sort of thing that would be
better taken care of with css3 or css+javascript? That is to say you
list the children of some elements as being display:none until they're
clicked, and then upon click you make it visible? This seems like it'd
be a bit slicker of an interface too. Would this be an acceptable
interface?

Regards,
Jason

That's okay with me and I'll work up a patch to demonstrate it. For a
company with many repos like Linaro, not displaying them does make the
front page load faster, but I've already sensed momentary confusion when
people try out our UI:

 https://git-ap.linaro.org/cgit/

I'll work up a dynamic version this today and throw it on another Linaro
mirror so you can compare the differences.

Great! The unicode characters ?, ?, ?, and ? might come in handy,
depending on how you implement it.

Also, to clarify --

The patch for cgit for this should probably be just adding
id="section_name" to the various divs. Then users' stylesheets and js
files can contain the necessary logic for which to hide and when to
hide it. That is, unless you can think of some really slick way to
roll this out to everybody that isn't too invasive. But I'm leaning
toward the, "possible via section name IDs" approach.

The difficulty with this is that:

1) we use table-row elements rather than divs for "sections"
2) because of #1, we require some type of java-script logic
3) there doesn't seem to be any support for user-supplied java-script

Its all doable, but as I start to look into this the diff is going to
grow a little more than you might be expecting.

I've just found a way to do this with having to only change one line of
code (add an "id" to each section row):

diff --git a/ui-repolist.c b/ui-repolist.c

                     strcmp(section, last_section)))) {

                        html("</td></tr>");
                        last_section = section;

With that simple change, I was able to use your pluggable "header"
option to create something that works. The JS isn't exactly something I
would be proud of, but it does accomplish what you've described:

 http://paste.ubuntu.com/23271843/

You can compare the two approaches:

 new js hackery: https://git-ap.linaro.org/cgit/
 original patch: https://git-ie.linaro.org/cgit/

My page loads are almost 2x slower with the new approach. However, they
still seem "fast enough".

Let me know what you think, and I can re-submit this one-liner if you
prefer.

Adding to the discussion that I submitted a patch for something akin to 
this changeset back in March, albeit, I'm no longer working at the 
company that I was when I submitted it (as such I don't have as much 
vested interest in getting that patchset in). In that case, I had 
patched in section name filters so that the end user could organize it 
however they pleased.  The net result is similar to what this patch 
series does.
