* Add support for base64-encoded hash values
The global template function 'get_file_hash' can now return a
base64-encoded hash value when its 'base64' parameter is set to true.
See discussion in #519.
* Fix integrity attribute's value in test site
SRI hash values must be base64-encoded.
* Update documentation about 'get_file_hash'
* Fix 'can_get_hash_for_static_files' unit test
* Move `load_tera` to `templates`
I don't know if this is a good place for it, conceptually. I'm moving it
there because I need to use it from `templates`, and `templates` can't
depend on `site`, because there's already a dependency in the opposite
direction.
* Load templates in `markdown` filter
This enables the `markdown` filter to handle shortcodes, as long as
those shortcodes don't access any context variables.
Addresses #1350
* Update documentation of `markdown` filter
* Only load templates for `markdown` filter once
* Clarify `markdown` filter documentation
This is a lightly edited version of what @southerntofu suggested.
* load_data() template function takes a `required` boolean flag
* Update tests for load_data()
* Add test to make sure invalid data always fails in load_data
* Better documentation, fixing a few typos

* Add a test for internal links in markdown filter

* Add support for loading Bibtex data.
* Add load_data() documentation for the bibtex format
* Force bibtex tags to be lower case.
Bibtex tags are case-insensitive, and this works around tera's case-sensitiveness.
* Improve the load_data() documentation for the bibtex format
* Per section/subsection feeds
* Added `generate_feed` variable to section front matter.
* Generate atom/rss feeds for sections/subsections that have the
`generate_feed` variable set to true (false by default); this works
independent of the `generate_feed` variable in the root `config.toml`
file, however, the name (and template) of the feed file for each section
is the same as `feed_filename` in `config.toml`, just located in the
root of each section.
* Slightly edited `atom.xml` and `rss.xml` so that they include the
section title (if any), and the url of a section, if it's a section
feed.
* Section feeds: tests
* Changed a couple of sections' front matter in order to generate feeds
for them for the test.
* Changed the can_build_feed test in site package to can_build_feeds and
included some assertions to make sure that section feeds are generated
when requested.
* Section feeds: documentation
* Added information about the section front matter variable
`generate_feed` in the section content page.
* Added information about section feeds in the feeds template page.
* Section feeds fix: use section.path for feed path
* Add support for SVG files to `get_image_metadata`
* Add support for SVG files to `get_image_metadata`
* Update documentation after adding SVG support
* Fix get_url(cachebust=true)
The previous implementation looked for static files in the wrong place.
Look in static_path, output_path and content_path. If file can't be
found in any of them, print a warning to stderr and fall back to using
a timestamp.
Add a test to ensure it also works in practice, not just in theory.
* Implement get_file_hash
If there is no response from the server, `load_data` would panic
with: `response status`.
This patch removes the `expect` in favor of an error message that we
couldn't get a response from the server for a given url.
Cache-busting was previously done with a compile-time timestamp. Change
to the SHA-256 hash of the file to avoid refreshing unchanged files.
The implementation could be used to add a new global fn (say,
get_file_hash) for subresource integrity use, but that's for another
commit.
Fixes#519.

Also change a few other things to use it, as noted in CHANGELOG.md.
TODO:
- Write a couple of tests: updated field, last_updated template variable
One slight open questions: should `updated` default to the value of
`date` rather than to None? Then pages with `date` could safely assume
`updated`.
The variable name matched the RSS tag it ended up in, but was misleading
about what it actually was—because if you actually want “last build
date”, you should use `now()`. (Due to the potential for edits, I think
that either there should be an official `updated` field on pages, or
that these templates should use `now()`.)
This includes several breaking changes, but they’re easy to adjust for.
Atom 1.0 is superior to RSS 2.0 in a number of ways, both technical and
legal, though information from the last decade is hard to find.
http://www.intertwingly.net/wiki/pie/Rss20AndAtom10Compared
has some info which is probably still mostly correct.
How do RSS and Atom compare in terms of implementation support? The
impression I get is that proper Atom support in normal content websites
has been universal for over twelve years, but that support in podcasts
was not quite so good, but getting there, over twelve years ago. I have
no more recent facts or figures; no one talks about this stuff these
days. I remember investigating this stuff back in 2011–2013 and coming
to the same conclusion. At that time, I went with Atom on websites and
RSS in podcasts. Now I’d just go full Atom and hang any podcast tools
that don’t support Atom, because Atom’s semantics truly are much better.
In light of all this, I make the bold recommendation to default to Atom.
Nonetheless, for compatibility for existing users, and for those that
have Opinions, I’ve retained the RSS template, so that you can escape
the breaking change easily.
I personally prefer to give feeds a basename that doesn’t mention “Atom”
or “RSS”, e.g. “feed.xml”. I’ll be doing that myself, as I’ll be using
my own template with more Atom features anyway, like author information,
taxonomies and making the title field HTML.
Some notes about the Atom feed template:
- I went with atom.xml rather than something like feed.atom (the .atom
file format being registered for this purpose by RFC4287) due to lack
of confidence that it’ll be served with the right MIME type. .xml is a
safer default.
- It might be nice to get Zola’s version number into the <generator>
tag. Not for any particularly good reason, y’know. Just picture it:
<generator uri="https://www.getzola.org/" version="0.10.0">
Zola
</generator>
- I’d like to get taxonomies into the feed, but this requires exposing a
little more info than is currently exposed. I think it’d require
`TaxonomyConfig` to preferably have a new member `permalink` added
(which should be equivalent to something like `config.base_url ~ "/" ~
taxonomy.slug ~ "/"`), and for the feed to get all the taxonomies
passed into it (`taxonomies: HashMap<String, TaxonomyTerm>`).
Then, the template could be like this, inside the entry:
{% for taxonomy, terms in page.taxonomies %}
{% for term in terms %}
<category scheme="{{ taxonomies[taxonomy].permalink }}"
term="{{ term.slug }}" label="{{ term.name }}" />
{% endfor %}
{% endfor %}
Other remarks:
- I have added a date field `extra.updated` to my posts and include that
in the feed; I’ve observed others with a similar field. I believe this
should be included as an official field. I’m inclined to add author to
at least config.toml, too, for feeds.
- We need to have a link from the docs to the source of the built-in
templates, to help people that wish to alter it.
Two main purposes of changes here:
- To make the formatting and indentation of the raw output prettier;
- To simplify the HTML yielded by dropping unnecessary bits.
The 404 changes are a tad more extensive, altering the actual wording to
match conventional stub 404 pages a little more.
* get_url takes an optionnal parameter
* Documentation about the 'lang' parameter of 'get_url'

Remove a link tag mistakenly imported from Atom XML namespace. The tag
was used to specify the link to the feed itself which is not supported
by RSS 2.0:
