[PATCH 1/1] filter: add libravatar email-filter lua script

Cool! Merged to master.

What's the story with Libravatar? The FLOSS version? Do they bootstrap
from Gravatar or is it a totally different database?

Cool, thanks!

> What's the story with Libravatar? The FLOSS version?

Yes, it is. Source code is available.

It's a different database, though they send a 302 redirect to gravatar if no
libravatar icon is available.

kernel.org's libravatar lua script

[mricon]

Hi, all:

We upgraded to 0.10.1 on kernel.org with libravatar support:
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/

As you'll notice, it's slightly different from the default gravatar
script, so here are our changes (using lua-md5 instead of luacrypto):

email-libravatar-korg.lua:
----
local md5 = require("md5")

function filter_open(email, page)
        buffer = ""
        hexdigest = md5.sumhexa(email:sub(2, -2):lower())
end

function filter_close()
        html("<span class='libravatar'><img class='inline'
src='//seccdn.libravatar.org/avatar/" .. hexdigest ..
"?s=13&amp;d=retro' /><img class='onhover'
src='//seccdn.libravatar.org/avatar/" .. hexdigest ..
"?s=128&amp;d=retro' /></span>" .. buffer)
        return 0
end

function filter_write(str)
        buffer = buffer .. str
end
----

The following css additions are required for the hover effect:

----
div#cgit span.libravatar img.onhover {
        display: none;
        border: 1px solid gray;
        padding: 0px;
        -webkit-border-radius: 4px;
        -moz-border-radius: 4px;
        border-radius: 4px;
        width: 128px;
        height: 128px;
}

div#cgit span.libravatar img.inline {
        -webkit-border-radius: 3px;
        -moz-border-radius: 3px;
        border-radius: 3px;
        width: 13px;
        height: 13px;
        margin-right: 0.2em;
        opacity: 0.4;
}

div#cgit span.libravatar:hover > img.onhover {
        display: block;
        position: absolute;
        margin-left: 1.5em;
        background-color: #eeeeee;
        box-shadow: 5px 5px 3px #bbb;
}
----

I would increase the opacity value a bit, but I do like it otherwise. :D

It's point four now. Make a suggestion and I'll change it to that. I
was having trouble deciding myself.

I would go with dot six or dot seven...
Anybody else with an opinion?

Nice. Note that this currently doesn't work when accessing the site via
HTTP [1, 2].
