SFEED(1)

NAME
sfeed - RSS and Atom parser

SYNOPSIS
sfeed [baseurl]

DESCRIPTION
sfeed reads RSS or Atom feed data (XML) from stdin. It writes the feed data in a TAB-separated format to stdout. If the baseurl argument is a valid absolute URL then the relative links or enclosures will be made an absolute URL.

TAB-SEPARATED FORMAT FIELDS
The items are output per line in a TAB-separated format.

For the fields title, id and author each whitespace character is replaced by a SPACE character. Control characters are removed.

The content field can contain newlines and these are escaped. TABs, newlines and '\' are escaped with '\', so it becomes: '\t', '\n' and '\\'. Other whitespace characters except spaces are removed. Control characters are removed.

The order and content of the fields are:

1. timestamp
    UNIX timestamp in UTC+0, empty if missing or on a parse failure.

2. title
    Title text, HTML code in titles is ignored and is treated as plain-text.

3. link
    Link

4. content
    Content, can have plain-text or HTML code depending on the content-type field.

5. content-type
    "html" or "plain" if it has content.

6. id
    RSS item GUID or Atom id.

7. author
    Item, first author.

8. enclosure
    Item, first enclosure.

9. category
    Item, categories, multiple values are separated by the '|' character.

EXIT STATUS

EXAMPLES

    curl -s 'https://codemadness.org/atom.xml' | sfeed

To convert the character set from a feed that is not UTF-8 encoded the iconv(1) tool can be used:

    curl -s 'https://codemadness.org/some_iso-8859-1_feed.xml' | \
    iconv -f iso-8859-1 -t utf-8 | \
    sfeed

EXAMPLE SETUP
1. Create a directory for the sfeedrc configuration and the feeds:

    mkdir -p ~/.sfeed/feeds

2. Copy the example sfeedrc(5) configuration:

    cp sfeedrc.example ~/.sfeed/sfeedrc
    $EDITOR ~/.sfeed/sfeedrc

Or import existing OPML subscriptions using sfeed_opml_import(1):

    sfeed_opml_import < file.opml > ~/.sfeed/sfeedrc

3. To update feeds and merge the new items with existing items:

    sfeed_update

4. Format feeds to a plain-text list:

    sfeed_plain ~/.sfeed/feeds/*

Or format feeds to a curses interface:

    sfeed_curses ~/.sfeed/feeds/*

There are also other formatting programs included. The README file has more examples.

CAVEATS
If a timezone for the timestamp field is not in the RFC 822 or RFC 3339 format it is not supported and the timezone is interpreted as UTC+0.
