From e49951eb3e1e1a8e7bad6d7471483e70b0865352 Mon Sep 17 00:00:00 2001 From: Mark H Weaver Date: Thu, 14 Feb 2013 04:15:25 -0500 Subject: Replace individual scripts with master 'guix' script. * scripts/guix.in: New script. * Makefile.am (bin_SCRIPTS): Add 'scripts/guix'. Remove 'guix-build', 'guix-download', 'guix-import', 'guix-package', and 'guix-gc'. (MODULES): Add 'guix/scripts/build.scm', 'guix/scripts/download.scm', 'guix/scripts/import.scm', 'guix/scripts/package.scm', and 'guix/scripts/gc.scm'. * configure.ac (AC_CONFIG_FILES): Add 'scripts/guix'. Remove 'guix-build', 'guix-download', 'guix-import', 'guix-package', and 'guix-gc'. * guix-build.in, guix-download.in, guix-gc.in, guix-import.in, guix-package.in: Remove shell script boilerplate. Move to guix-COMMAND.in to guix/scripts/COMMAND.scm. Rename module from (guix-COMMAND) to (guix scripts COMMAND). Change "guix-COMMAND" to "guix COMMAND" in usage help string. * pre-inst-env.in: Add "@abs_top_builddir@/scripts" to the front of $PATH. Export $GUIX_UNINSTALLED. * tests/guix-build.sh, tests/guix-daemon.sh, tests/guix-download.sh, tests/guix-gc.sh, tests/guix-package.sh: Use "guix COMMAND" instead of "guix-COMMAND". * doc/guix.texi: Replace all occurrences of "guix-COMMAND" with "guix COMMAND". * po/POTFILES.in: Update. --- .gitignore | 6 +- Makefile.am | 11 +- configure.ac | 9 +- doc/guix.texi | 82 +++--- guix-build.in | 317 --------------------- guix-download.in | 164 ----------- guix-gc.in | 183 ------------ guix-import.in | 137 --------- guix-package.in | 706 ---------------------------------------------- guix/scripts/build.scm | 304 ++++++++++++++++++++ guix/scripts/download.scm | 151 ++++++++++ guix/scripts/gc.scm | 165 +++++++++++ guix/scripts/import.scm | 124 ++++++++ guix/scripts/package.scm | 693 +++++++++++++++++++++++++++++++++++++++++++++ guix/ui.scm | 38 ++- po/POTFILES.in | 8 +- pre-inst-env.in | 11 +- scripts/guix.in | 56 ++++ tests/guix-build.sh | 26 +- tests/guix-daemon.sh | 6 +- tests/guix-download.sh | 12 +- tests/guix-gc.sh | 24 +- tests/guix-package.sh | 56 ++-- 23 files changed, 1654 insertions(+), 1635 deletions(-) delete mode 100644 guix-build.in delete mode 100644 guix-download.in delete mode 100644 guix-gc.in delete mode 100644 guix-import.in delete mode 100644 guix-package.in create mode 100644 guix/scripts/build.scm create mode 100644 guix/scripts/download.scm create mode 100644 guix/scripts/gc.scm create mode 100644 guix/scripts/import.scm create mode 100644 guix/scripts/package.scm create mode 100644 scripts/guix.in diff --git a/.gitignore b/.gitignore index ecdaed2ef0..302e473fd8 100644 --- a/.gitignore +++ b/.gitignore @@ -34,7 +34,6 @@ config.cache /po/remove-potcdate.sin /po/stamp-po /po/guix.pot -/guix-build /tests/*.trs /INSTALL /m4/* @@ -44,12 +43,9 @@ config.cache /doc/guix.pdf /doc/stamp-vti /doc/version.texi -/guix-download /gnu/packages/bootstrap/x86_64-linux/guile-2.0.7.tar.xz /gnu/packages/bootstrap/i686-linux/guile-2.0.7.tar.xz -/guix-package /guix/config.scm -/guix-import /nix/nix-daemon/nix-daemon.cc /nix/config.h /nix/config.h.in @@ -64,7 +60,7 @@ stamp-h[0-9] /nix/scripts/list-runtime-roots /test-env /nix/nix-setuid-helper/nix-setuid-helper.cc -/guix-gc +/scripts/guix /doc/guix.aux /doc/guix.cp /doc/guix.cps diff --git a/Makefile.am b/Makefile.am index 7a1b6ad163..5932e1350a 100644 --- a/Makefile.am +++ b/Makefile.am @@ -18,17 +18,18 @@ # along with GNU Guix.
