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.

The default configuration is sufficient to get Zola running locally but not more than that.
|
|
It follows the philosophy of paying for only what you need; almost everything is turned off by default.
|
|
|
|
To change the configuration, edit the `config.toml` file.
|
|
If you are not familiar with TOML, have a look at [the TOML spec](https://github.com/toml-lang/toml).
|
|
|
|
Only the `base_url` variable is mandatory; everything else is optional. All configuration variables
|
|
used by Zola as well as their default values are listed below:
|
|
|
|
|
|
```toml
|
|
# The base URL of the site; the only required configuration variable.

## Slugification strategies
|
|
|
|
By default, Zola will turn every path, taxonomies and anchors to a slug, an ASCII representation with no special characters.
|
|
You can however change that strategy for each kind of item, if you want UTF-8 characters in your URLs for example. There are 3 strategies:
|
|
|
|
- `on`: the default one, everything is turned into a slug
|
|
- `safe`: characters that cannot exist in files on Windows (`<>:"/\|?*`) or Unix (`/`) are removed, everything else stays
|
|
- `off`: nothing is changed, your site might not build on some OS and/or break various URL parsers
|
|
|
|
Since there are no filename issues with anchors, the `safe` and `off` strategies are identical in their case: the only change
|
|
is space being replaced by `_` since a space is not valid in an anchor.
|
|
|
|
Note that if you are using a strategy other than the default, you will have to manually escape whitespace and Markdown
|
|
tokens to be able to link to your pages. For example an internal link to a file named `some space.md` will need to be
|
|
written like `some%20space.md` in your Markdown files.
