#### 9.4.3 Listing components

The command `--list-components` will list all components that can be configured with `gpgconf`. Usually, one component will correspond to one GnuPG-related program and contain the options of that program’s configuration file that can be modified using `gpgconf`. However, this is not necessarily the case. A component might also be a group of selected options from several programs, or contain entirely virtual options that have a special effect rather than changing exactly one option in one configuration file.

A component is a set of configuration options that semantically belong together. Furthermore, several changes to a component can be made in an atomic way with a single operation. The GUI could for example provide a menu with one entry for each component, or a window with one tabulator sheet per component.

The command `--list-components` lists all available components, one per line. The format of each line is:

`name:description:pgmname:`

name

  This field contains a name tag of the component. The name tag is used to specify the component in all communication with `gpgconf`. The name tag is to be used verbatim. It is thus not in any escaped format.

description

  The string in this field contains a human-readable description of the component. It can be displayed to the user of the GUI for informational purposes. It is percent-escaped and localized.

pgmname

  The string in this field contains the absolute name of the program’s file. It can be used to unambiguously invoke that program. It is percent-escaped.

Example:

    $ gpgconf --list-components
    gpg:GPG for OpenPGP:/usr/local/bin/gpg2:
    gpg-agent:GPG Agent:/usr/local/bin/gpg-agent:
    scdaemon:Smartcard Daemon:/usr/local/bin/scdaemon:
    gpgsm:GPG for S/MIME:/usr/local/bin/gpgsm:
    dirmngr:Directory Manager:/usr/local/bin/dirmngr:
