* guix/build-system/trivial.scm: New file.
* Makefile.am (MODULES): Add it.
* tests/packages.scm ("trivial"): New test.
* guix/packages.scm (package-derivation): Allow SOURCE to be #f.
This is a first step towards bootstrapping from a set of pre-built,
statically-linked binaries.
* guix/build-system/gnu.scm (package-with-explicit-inputs,
standard-inputs): New procedure.
(%store): New variable.
(%standard-inputs): Remove.
(gnu-build): New `implicit-inputs?' keyword parameter. Use it to
choose whether to use `(standard-inputs SYSTEM)' or the empty list.
* distro/base.scm (guile-2.0): Remove dependency on XZ, which is now
implicit.
(%bootstrap-inputs, gcc-boot0, binutils-boot0, linux-headers-boot0,
%boot1-inputs, glibc-final, %boot2-inputs, m4-boot2, gmp-boot2,
mpfr-boot2, mpc-boot2, %boot3-inputs, gcc-final, %boot4-inputs,
%final-inputs): New variables.
* guix/packages.scm (transitive-inputs): New procedure.
(package-transitive-inputs): Rewrite in terms of `transitive-inputs'.
(package-transitive-propagated-inputs): New procedure.
* guix/build/utils.scm (substitute): Do not pass the OUT to PROC; use
`list-matches' instead of `regexp-exec' and pass a list of matches to
PROC. Expect PROC to return a string, and output that. Fold over
RX+PROC in order. Use `(read-line p 'concat)' to include the trailing
delimiter in LINE.
(substitute*): Produce code to iterate over the matches, and return a
string, which includes anything from the original line that's in
between matches.
* distro/base.scm (gcc-4.7, glibc): Adjust accordingly: remove use
of (ice-9 regex) and `regexp-substitute/global'; return a string.
* guix/derivations.scm (%guile-for-build): Use `nixpkgs-derivation*'
instead of `nixpkgs-derivation'.
(build-expression->derivation): New `guile-for-build' keyword
parameter. Use it.
* guix/build/gnu-build-system.scm (set-paths): Add new `path-exclusions'
parameter; honor it.
* guix/build-system/gnu.scm (gnu-build): New `path-exclusions' keyword
parameter; pass it to BUILDER.
* distro/base.scm (gcc-4.7): Exclude "libc" from $LIBRARY_PATH.
* guix/build/gnu-build-system.scm (strip): New procedure.
(%standard-phases): Add it.
* guix/build-system/gnu.scm (gnu-build): New `strip-binaries?',
`strip-flags', and `strip-directories' keyword parameters. Pass them
to BUILDER.
* guix/packages.scm (&package-error, &package-input-error): New
condition types.
(package-derivation): Raise a `&package-input-error' when no match is
made.
* guix/build/utils.scm (patch-shebang): Add an optional `path'
parameter. Change SHEBANG-RX to match the whole interpreter file
name. Don't patch when BIN and CMD are the same. Add docstring.
* guix/build/gnu-build-system.scm (patch-shebangs): New procedure.
(%standard-phases): Add it.
* guix/build-system/gnu.scm (gnu-build): New `patch-shebangs?' keyword
parameter. Pass it to the builder's `gnu-build'.
* Makefile.am (.scm.go): Define $NIX_INSTANTIATE.
(TESTS_ENVIRONMENT): Likewise, and define $NIX_HASH.
* guix/utils.scm (nixpkgs-derivation): Use $NIX_INSTANTIATE when
defined.
* tests/utils.scm (%nix-hash): New variable.
("sha256 & bytevector->nix-base32-string"): Use it.
* guix/packages.scm (package-transitive-inputs): New procedure.
(package-derivation): Use it to compute INPUTS.
* tests/packages.scm (dummy-package): New macro.
("package-transitive-inputs"): New test.
* guix/build/utils.scm (substitute): Change to accept a `pattern+procs'
parameter. Iterate over it.
(substitute*): Adjust accordingly.
* distro/base.scm (guile-1.8): Adjust accordingly.
* guix/build/utils.scm (let-matches, substitute*): New macros.
* distro/base.scm (guile-1.8): Use `substitute*' instead of
`substitute'. Remove the #:modules argument.
* guix/build/gnu-build-system.scm (set-paths): Dump the value of
environment variables in the `environment-variables' files, similar to
what Nixpkgs does.
* guix/build/gnu-build-system.scm (patch): New procedure.
(%standard-phases): Add `patch'.
* guix/build-system/gnu.scm (gnu-build): Add `patches' and `patch-flags'
parameters. Pass them on.
