implicitly added to the build process, and in the list of phases
executed. Some of these build systems are listed below.
@defvar agda-build-system
This variable is exported by @code{(guix build-system agda)}. It
implements a build procedure for Agda libraries.
It adds @code{agda} to the set of inputs. A different Agda can be
specified with the @code{#:agda} key.
The @code{#:plan} key is a list of cons cells @code{(@var{regexp}
. @var{parameters})}, where @var{regexp} is a regexp that should match
the @code{.agda} files to build, and @var{parameters} is an optional
list of parameters that will be passed to @code{agda} when type-checking
it.
When the library uses Haskell to generate a file containing all imports,
the convenience @code{#:gnu-and-haskell?} can be set to @code{#t} to add
@code{ghc} and the standard inputs of @code{gnu-build-system} to the
input list. You will still need to manually add a phase or tweak the
@code{'build} phase, as in the definition of @code{agda-stdlib}.
@end defvar
@defvar ant-build-system
This variable is exported by @code{(guix build-system ant)}. It
implements the build procedure for Java packages that can be built with
