## 5 Configuration

All Newsticker options are customizable, i.e. they can be changed with Emacs customization methods: Call the command `customize-group` and enter ‘`newsticker`’ for the customization group.

All Newsticker options have reasonable default values, so that in most cases it is not necessary to customize settings before starting Newsticker for the first time.

The following list shows the available groups of newsticker options and some of the most important options.

- `newsticker-retrieval` contains options that define which news feeds are retrieved and how this is done.
  - `newsticker-url-list` defines the list of headlines which are retrieved.
  - `newsticker-retrieval-method` defines how headlines are retrieved. This is either done using Emacs' built-in download capabilities or using an external tool.
  - `newsticker-retrieval-interval` defines how often headlines are retrieved.
- `newsticker-headline-processing` contains options that define how the retrieved headlines are processed.
  - `newsticker-keep-obsolete-items` decides whether unread headlines that have been removed from the feed are kept in the Newsticker cache.
  - `newsticker-auto-mark-filter-list` provides the possibility to automatically mark headlines as immortal or old.
- `newsticker-hooks` contains options for hooking other Emacs commands to newsticker functions.
  - `newsticker-new-item-functions` allows for automatic processing of headlines. See `newsticker-download-images', and `newsticker-download-enclosures' for sample functions.
  - The subgroup `newsticker-plainview-hooks` contains hook which apply to the plainview reader only.
- `newsticker-miscellaneous` contains other Newsticker options.

  - `newsticker-ticker-interval` and `newsticker-scroll-smoothly` define how headlines are shown in the echo area.
- `newsticker-reader` contains options for adjusting the headline reader.
  - `newsticker-frontend` determines the actual headline reader. The “plainview” reader uses a single buffer, the “treeview” uses separate buffers and windows.
