Commit Message

  This commit adds a new service type to generate configuration file for the mpv
media player.

Originally I attempted to use Guix Records (via define-configuration) for
this, but ran into the bug #74748, so I had to switch to procedures instead.
The usage is (hopefully) sufficiently described in the documentation.  When
the bug is resolved, I will update it to use define-configuration instead.

The full list of supported options is documented, however I decided to *not*
document types and purpose for each individual fields.  While I had mostly
working prototype to extract the documentation from mpv, once I realized it
would be few 10k of lines added, I decided it is not worth it.  It would bloat
the .texi file (by more than 50%), be hard to maintain and, in my opinion,
would not provide enough value to justify that.  The current version seems
like sane middle ground.

* gnu/home/services/mpv.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Register it.
* doc/guix.texi (mpv Media Player): Document it.

+@c This is ugly, but upstream does *not* capitalize the ``m'' even when
+@c at the beginning of a sentence.  So let us follow the branding.
+@node mpv Media Player
+@subsection mpv Media Player
+
+@cindex mpv, Home Service
+@cindex mpv, configuration
+Configuring the @uref{https://mpv.io/, mpv media player} can be somewhat
+daunting task, due to the sheer amount of options available, especially
+if one wants to be able to inherit the configuration in their code.  The
+@code{home-mpv-service-type} is provided to help with that problem.
+When the service is added to your home environment, file based on the
+passed configuration is generated and placed into the correct location.
+
+Due to the bug #74748, it does not use Guix Records to represent the
+configuration, but uses keyword arguments to achieve similar result.
+Example follows:
+
+@lisp
+(service home-mpv-service-type
+         (make-home-mpv-configuration
+          #:global (make-mpv-profile-configuration
+                    #:fullscreen? #t
+                    #:alang '("jpn" "eng"))))
+@end lisp
+
+@defvar home-mpv-service-type
+This is the type of the mpv home service, whose value is a
+@code{home-mpv-configuration} object.
+@end defvar
+
+@deffn {Procedure} make-home-mpv-configuration
+Return a new instance of @code{home-mpv-configuration}.  Available
+keyword arguments are:
+
+@table @asis
+@item @code{inherit} (default: @code{#t})
+Inherit fields from an another instance.
+
+@item @code{global} (default: @code{(make-mpv-profile-configuration)})
+The global configuration preceding all profiles.
+
+@item @code{profiles} (default: @code{()})
+An alist containing configuration for any additional profiles to include
+in the configuration file.
+
+@lisp
+(make-home-mpv-configuration
+ #:profiles `((fullscreen . ,(make-mpv-profile-configuration
+                              #:fullscreen? #t))))
+@end lisp
+
+@item @code{extra-config} (default: @code{#f})
+Additional content to include in the configuration file.  It is placed
+at the end of the file.
+
+@end table
+@end deffn
+
+@deffn {Procedure} make-mpv-profile-configuration
+Return a new instance of @code{mpv-profile-configuration}.  As above, it
+also supports the @code{#:inherit} argument.  Additionally it supports
+keyword arguments named after the options of @command{mpv}.  Hence
+@option{--fullscreen} (or @code{fullscreen} in the configuration file)
+becomes @code{#:fullscreen?}.
+
+Few options are using their aliases instead.  @option{audio} instead of
+@option{aid}, @option{video} instead of @option{vid}, @option{sub}
+instead of @option{sid}, @option{screenshot-directory} instead of
+@option{screenshot-dir} and @option{watch-later-directory} instead of
+@option{watch-later-dir}.
+
+Valid values for the fields depend on their type.
+
+@table @asis
+@item Flags
+The value should be @code{#f} or @code{#t}.
+
+@item Numerical fields
+Integer and integer64 fields are validated by @code{integer?}, float and
+double fields by @code{real?}.  Ranges are checked when applicable.
+
+@item Aspect
+Same as integer.
+
+@item ByteSize
+Same as integer64.
+
+@item Choice
+The value should be a symbol representing member of the enumeration.  If
+the choice has @samp{or ...} part, it can also be value of that
+alternative type.
+
+@item @var{type} list
+The value should be a list of the @var{type}.
+
+@end table
+
+Other types accept strings, with validation of the values where possible
+(e.g. type @samp{Color} is validated, but type @samp{Audio channels or
+channel map} is not).
+
+The full list of currently supported keyword arguments is below.  For
+the types, allowed values and full description please refer to the
+@command{mpv --list-options} and
+@uref{https://mpv.io/manual/stable/#options, mpv manual}.
+
+Only set fields are outputted to the configuration file.  Accessors are
+provided for every field, returning either their value or a sentinel
+object @code{%unset-value} (from @code{(gnu services configuration)}).
