@ -2932,6 +2932,49 @@ The returned source tarball is the result of applying any patches and
code snippets specified in the package's @code{origin} (@pxref{Defining
Packages}).
@item --sources
Fetch and return the source of @var{package-or-derivation} and all their
dependencies, recursively. This is a handy way to obtain a local copy
of all the source code needed to build @var{packages}, allowing you to
eventually build them even without network access. It is an extension
of the @code{--source} option and can accept one of the following
optional argument values:
@table @code
@item package
This value causes the @code{--sources} option to behave in the same way
as the @code{--source} option.
@item all
Build all packages' source derivations, including any source that might
be listed as @code{inputs}. This is the default value.
@example
$ guix build --sources tzdata
The following derivations will be built:
/gnu/store/@dots{}-tzdata2015b.tar.gz.drv
/gnu/store/@dots{}-tzcode2015b.tar.gz.drv
@end example
@item transitive
Build all packages' source derivations, as well as all source
derivations for packages' transitive inputs. This can be used e.g. to
prefetch package source for later offline building.
@example
$ guix build --sources=transitive tzdata
The following derivations will be built:
/gnu/store/@dots{}-tzcode2015b.tar.gz.drv
/gnu/store/@dots{}-findutils-4.4.2.tar.xz.drv
/gnu/store/@dots{}-grep-2.21.tar.xz.drv
/gnu/store/@dots{}-coreutils-8.23.tar.xz.drv
/gnu/store/@dots{}-make-4.1.tar.xz.drv
/gnu/store/@dots{}-bash-4.3.tar.xz.drv
@dots{}
@end example
