1 Introduction

## About Feeder
Feeder is a syndication feed library. It presents a general protocol for representation of feed items, as well as a framework to translate these objects from and to external formats. It also implements the RSS 2.0 and Atom formats within this framework.

## Translating Feeds
During this document code examples will assume that ``org.shirakumo.feeder`` has the local nickname ``feeder``.

In order to parse a feed, simply call ``parse-feed``:

:: common lisp
(feeder:parse-feed "test1http://example.com" T)
::

It should determine the format used automatically and construct standardised ``feed`` instances out of the source. In order to reverse the process and turn a ``feed`` into an external format again, simply call ``serialize-feed``:

:: common lisp
(feeder:serialize-feed (first *) 'feeder:atom)
::

Note that while parsing is very lenient, serialising is not, and it will error if certain attributes are missing or malformed. You therefore cannot always round-trip feeds like this.

For ``xml-format``s, the resulting value of ``serialize-feed`` will be a ``plump:node`` that can be turned into a string with ``plump:serialize``:

:: common lisp
(plump:serialize * NIL)
::

## Generating Feeds
In order to generate feeds, you need to translate whatever internal representation of your items you have into ``entry`` instances, and then bundle them together into a ``feed`` instance. Both ``feed`` and ``entry`` instances require in the very least an ``:id``, ``:link``, ``:title``, and ``:summary``. The ``:id`` can be whatever you want it to be, but it should be an ID that uniquely identifies your item for all time, preferably even globally so. If the link to your item can be used as a unique identifier, you can supply the same ``link`` instance to ``:id`` and ``:link``. The ``:summary`` can either be a string of plain text content, or a ``plump:node`` for HTML content.

You should also strongly consider filling in the ``:authors`` and ``:published-on`` fields, as well as the ``:content`` field on ``entry`` instances. For the ``:content``, you may supply either plain text or HTML, just as for the ``:summary``.

In order to bundle the ``entry`` instances into the ``feed``, simply put them into a list and set that as the ``feed``'s ``:content``.

When generating and feed objects and serialising them, the system will check for validity of elements to some limited extent. For instance, required slots that are missing will be reported with errors. Generally whenever an error is signalled, plenty of restarts will be available to help deal with the problem both interactively and in an automated fashion.

Please see the descriptions of ``feed-condition``'s subtypes for more information on the error circumstances and possible restarts.

## Extending Feeds and Formats
If you need to extend the feed objects or add new feed formats, the functions you should look at are ``parse-to`` and ``serialize-to``. In both cases you should add methods to them that specialise on all three arguments, at least one of which must be on a class you control.

Assuming for instance you define an extended ``person`` that has an additional ``location`` field. Ensuring this field is output into the ``atom`` format, you would do something like this:

:: common lisp
(defclass extended-person (feeder:person)
  ((location :initarg :location :initform NIL :accessor location)))

(defmethod feeder:serialize-to ((target plump:element) (person extended-person) (format feeder:atom))
  (call-next-method)
  (when (location person)
    (feeder:make-element target :location - (location person))))
::

When parsing we need to substitute our new class for the instance to use when creating ``person``s. To do so, we require a new ``format`` subclass, and a method on ``instance-for-type``:

:: common lisp
(defclass extended-format (feeder:atom)
  ())

(defmethod feeder:instance-for-type ((type (eql 'person)) (format extended-format))
  (feeder:instance-for-type 'extended-person format))
::

Finally we can read out the field in a ``parse-to`` method:

:: common lisp
(defmethod feeder:parse-to ((person extended-person) (node plump:element) (format extended-format))
  (call-next-method)
  (feeder:with-child (child node :location)
    (setf (location person) (feeder:text child))))
::

Naturally, it is also possible to define entirely new formats that don't necessarily serialise to XML.

5 Definitions

Definitions are sorted by export status, category, package, and then by lexicographic order.

5.1 Exported definitions

5.1.1 Macros

Macro: make-element PARENT TAG-NAME &body ATTRIBUTES

Construct a new XML element.

ATTRIBUTES should be a plist of alternating keys and values. A key may either be a string or a symbol. If a symbol, it is treated as the attribute name in lowercase. The attribute is only set if the value is non-NIL.

If the key is a symbol with the name "-", the value is used as the text content of the element.

For example, constructing an element like

<foo bar="baz">bam</foo>

would be

(make-element parent "foo"
:bar "baz"
- "bam")

toolkit.lisp (file)

Macro: with-children (NAME ROOT) &body CLAUSES

Scans through the immediate children of ROOT and executes bodies as matching.

The format should be as follows:

CLAUSES ::= (TAG . form*)*
TAG — A string designator

The forms of a clause are executed with NAME bound to a PLUMP:ELEMENT whose tag-name matches that specified in the clause. Tag names are matched case-insensitively.

Generic Function: parse-feed SOURCE FORMAT

Parses the given source into standardised feed objects according to the specified format.

If FORMAT is T, the format is determined automatically depending on
the source’s contents.

Returns a list of FEED instances.

This function should construct the appropriate base object and then
call PARSE-TO.

5.1.4 Conditions

Condition: argument-missing ()

Error signalled when a required argument is missing.

This usually happens when you try to create an instance of an object but omitted an argument that is required to create a valid feed.

When this condition is signalled, the following restarts are available

- USE-VALUE
Requires an argument that is then used for the missing argument. - CONTINUE
Set the slot to NIL anyway.

Class: rss ()

RSS 2.0 Feed Format

As defined in https://validator.w3.org/feed/docs/rss2.html with select extensions such as content:encoded.

RSS is a very "web" format, which is to say that the files claiming to be RSS that can be found out there all do not adhere to any strict specifications, or anything at all for that matter. This makes parsing and dealing with RSS a pain in the ass.

This parser performs a best-effort at parsing the content you hand it, and attempts to standardise and culminate certain features together as appropriate. It should not error when parsing a feed, but may miss or misinterpret certain values present in the raw feed data. For instance, of duplicated tags that should only exist once, only the last tag is actually preserved in the generated objects.

Serialising to RSS will follow the description as closely as possible without touching undefined parts.
