(TESTS): Add `tests/packages.scm'. (EXTRA_DIST): New variable. * guix/packages.scm, distro/base.scm, tests/packages.scm: New files. * guix/http.scm (http-fetch): Make `name' an optional argument, to match the expectations of `package-source-derivation'. --- Makefile.am | 8 ++- distro/base.scm | 49 +++++++++++++++++ guix/http.scm | 3 +- guix/packages.scm | 127 +++++++++++++++++++++++++++++++++++++++++++++ tests/packages.scm | 51 ++++++++++++++++++ 5 files changed, 235 insertions(+), 3 deletions(-) create mode 100644 distro/base.scm create mode 100644 guix/packages.scm create mode 100644 tests/packages.scm diff --git a/Makefile.am b/Makefile.am index b2b6d943a5..8b5713b1d9 100644 --- a/Makefile.am +++ b/Makefile.am @@ -26,7 +26,9 @@ MODULES = \ guix/build/gnu-build-system.scm \ guix/build/http.scm \ guix/build/utils.scm \ - guix.scm + guix/packages.scm \ + guix.scm \ + distro/base.scm GOBJECTS = $(MODULES:%.scm=%.go) @@ -36,13 +38,15 @@ nobase_nodist_guilemodule_DATA = $(GOBJECTS) TESTS = \ tests/builders.scm \ tests/derivations.scm \ - tests/utils.scm + tests/utils.scm \ + tests/packages.scm TESTS_ENVIRONMENT = \ NIXPKGS="$(NIXPKGS)" \ GUILE_LOAD_COMPILED_PATH="$(top_builddir):$$GUILE_LOAD_COMPILED_PATH" \ $(GUILE) -L "$(top_srcdir)" +EXTRA_DIST = $(TESTS) CLEANFILES = $(GOBJECTS) *.log .scm.go: diff --git a/distro/base.scm b/distro/base.scm new file mode 100644 index 0000000000..d830d6efef --- /dev/null +++ b/distro/base.scm @@ -0,0 +1,49 @@ +;;; Guix --- Nix package management from Guile. -*- coding: utf-8 -*- +;;; Copyright (C) 2012 Ludovic Courtès +;;; +;;; This file is part of Guix. +;;; +;;; Guix is free software; you can redistribute it and/or modify it +;;; under the terms of the GNU General Public License as published by +;;; the Free Software Foundation; either version 3 of the License, or (at +;;; your option) any later version. +;;; +;;; Guix is distributed in the hope that it will be useful, but +;;; WITHOUT ANY WARRANTY; without even the implied warranty of +;;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
