@item
The @code{inputs} field specifies inputs to the build process---i.e.,
build-time or run-time dependencies of the package. Here, we define an
input called @code{"gawk"} whose value is that of the @code{gawk}
build-time or run-time dependencies of the package. Here, we add
an input, a reference to the @code{gawk}
variable; @code{gawk} is itself bound to a @code{<package>} object.

@cindex inputs, of packages
These fields list dependencies of the package. Each one is a list of
tuples, where each tuple has a label for the input (a string) as its
first element, a package, origin, or derivation as its second element,
and optionally the name of the output thereof that should be used, which
defaults to @code{"out"} (@pxref{Packages with Multiple Outputs}, for
more on package outputs). For example, the list below specifies three
inputs:
These fields list dependencies of the package. Each element of these
lists is either a package, origin, or other ``file-like object''
(@pxref{G-Expressions}); to specify the output of that file-like object
that should be used, pass a two-element list where the second element is
the output (@pxref{Packages with Multiple Outputs}, for more on package
outputs). For example, the list below specifies three inputs:
@lisp
(list libffi libunistring
`(,glib "bin")) ;the "bin" output of GLib
@end lisp
In the example above, the @code{"out"} output of @code{libffi} and
@code{libunistring} is used.
@quotation Compatibility Note
Until version 1.3.0, input lists were a list of tuples,
where each tuple has a label for the input (a string) as its
first element, a package, origin, or derivation as its second element,
and optionally the name of the output thereof that should be used, which
defaults to @code{"out"}. For example, the list below is equivalent to
the one above, but using the @dfn{old input style}:
@lisp
;; Old input style (deprecated).
`(("libffi" ,libffi)
("libunistring" ,libunistring)
("glib:bin" ,glib "bin")) ;the "bin" output of Glib
("glib:bin" ,glib "bin")) ;the "bin" output of GLib
@end lisp
This style is now deprecated; it is still supported but support will be
removed in a future version. It should not be used for new package
definitions.
