@end defvr
@defvr {Scheme Variable} julia-build-system
This variable is exported by @code{(guix build-system julia)}. It implements
the build procedure used by @uref{https://julialang.org/, julia} packages,
which essentially is similar to running @command{julia -e 'using Pkg;
Pkg.add(package)'} in an environment where @code{JULIA_LOAD_PATH} contains the
paths to all Julia package inputs. Tests are run not run.
Julia packages require the source @code{file-name} to be the real name of the
package, correctly capitalized.
For packages requiring shared library dependencies, you may need to write the
@file{/deps/deps.jl} file manually. It's usually a line of @code{const
variable = /gnu/store/libary.so} for each dependency, plus a void function
@code{check_deps() = nothing}.
Some older packages that aren't using @file{Package.toml} yet, will require
this file to be created, too. The function @code{julia-create-package-toml}
helps creating the file. You need to pass the outputs and the source of the
package, it's name (the same as the @code{file-name} parameter), the package
uuid, the package version, and a list of dependencies specified by their name
and their uuid.
@end defvr
@defvr {Scheme Variable} minify-build-system
This variable is exported by @code{(guix build-system minify)}. It
implements a minification procedure for simple JavaScript packages.
