There is a tension between looking up the avatar at post time
and build time. I have not yet decided which is better.
Lookup at build time has the benefit that if a user changes their
email address, or sets up their own federated libravatar
server, on rebuild their new avatar will show up.
It also allows getting a https version of the avatar easily if
the site was using http but was changed to use https.
And it can look up avatars for posts that have already been made.
Which is a nice thing, especially as we roll this out, eh?
But it has a drawback, that it depends on the sessiondb contents
for emails and so rebuilding a site w/o that will lose info.
And, it means dns lookups every time a comment is rendered. A page
with a lot of comments on it would render them all whenever another is
posted or the page is changed, and that could significantly slow things
down. (This could be amelorated by caching the lookups.)
Since I'm undecided, I have moved it into a function that could be called
either way. Currently looking up only at post time.
* comments: Add avatar picture of comment author, using Libravatar::URL
when available. The avatar is looked up based on (Thanks, Francois Marier)
* Recommend libgravatar-url-perl, which contains Libravatar::URL.
Don't fail if libravatar fails for some reason. Reasons I can think
of:
* too old version to do openid lookups (fall back to email lookup)
* network problem perhaps
This has been a while coming. It turns out that non-excutable setup files
have a number of benefits. Also, I find YAML setup files easier to edit
myself, and I suspect many users will prefer not needing to deal with
perl syntax.
Oddly, this hadn't caused any visible breakage. Possibly inline,
which is the only thing to use targetpage, resolves the function
to the "real" one before po gets loaded?
If the inline plugin is not being loaded, or is perhaps loaded after po
(when IkiWiki::Setup::getsetup loads all the plugins, for example),
po should not inject its custom rootpage sub, as that will lead to a
redefinition error message when inline loads.
