* configure.ac: Don't check for 'sed' and 'cp' programs which are
considered portable. Don't check for 'head' and 'which' programs which
are not required.
Before that change, it was possible for 'make' to try linking programs
before 'src/libmcron.a' was built.
* Makefile.am (bin_mcron_DEPENDENCIES, bin_cron_DEPENDENCIES)
(bin_crontab_DEPENDENCIES): Add '$(noinst_LIBRARIES)'.
* tests/schedule.sh: New test.
* Makefile.am (TESTS): Add it.
* src/mcron/job-specifier.scm (configuration-time): Use
SOURCE_DATE_EPOCH for reproducible tests.
This procedure is a more generic and less coupled version of
'get-schedule' which has been kept for backward compatibility and
deprecated.
* src/mcron/base.scm (display-schedule): New procedure.
(get-schedule): Move to ...
* src/mcron/core.scm: ... here.
* src/mcron/scripts/cron.scm (main): Use 'display-schedule'.
* src/mcron/scripts/mcron.scm (main): Likewise.
* doc/mcron.texi (The base module): Document it.
* tests/init.sh: New test framework from Gnulib.
* tests/basic.sh: New test.
* Makefile.am (TESTS): Add it.
(TEST_EXTENSIONS): Add '.sh'.
(SH_LOG_COMPILER): Use 'pre-inst-env'.
(EXTRA_DIST): Add 'tests/init.sh'.
* build-aux/pre-inst-env.in: export $srcdir for shell tests.
'argp' is a convenient and maintainable way to parse command line arguments.
Guile doesn't offer an equivalent of this, so the command line handling has
been moved to C.
* src/mcron.c (parse_args, parse_opt): New functions.
(inner_main): Call 'parse_args'.
* src/mcron/scripts/mcron.scm (show-help, %options): Delete.
(main): Remove command line handling.
Unlike C code where debugging impose the "-g" compilation flags. This
debugging option only affects Guile code, so using an environment variable
works better since it doesn't impose to recompile Mcron or to edit
"config.scm".
* configure.ac: Remove "--enable-debug" configure option.
* src/mcron/config.scm.in (config-debug): Use MCRON_DEBUG environment variable
to trigger the debug mode at runtime.
* configure.ac: Define "--disable-multi-user" option instead of
"--enable-no-vixie-clobber".
* Makefile.am (install-exec-hook) [MULTI_USER]: Only set crontab setuid bit.
(bin_PROGRAMS): Keep only 'mcron' by default.
(bin_PROGRAMS) [MULTI_USER]: Add 'crontab'
(sbin_PROGRAMS) [MULTI_USER]: Add 'cron'.
(noinst_PROGRAMS) [!MULTI_USER]: Add 'cron' and 'crontab'.
(dist_man_MANS): Move 'crontab.1' and 'cron.8' ...
(extra_mans): here. New variable.
(dist_man_MANS) [MULTI_USER]: Add it.
(all-local) [!MULTI_USER]: New target. Depend on it.
(EXTRA_DIST) [!MULTI_USER]: Distribute it.
(MAINTAINERCLEANFILES): Clean it.
* configure.ac: Use 'GUILE_PKG' and 'GUILE_PROGS'. Remove explicit Guile
version check and check for 'guild'. Honor $GUILE_EFFECTIVE_VERSION in
'moduledir'.
* src/wrapper.c (wrap_env_path): New function.
(main): Use it.
(inner_main): Let 'wrap_env_path' set the environment variables.
Don't use 'scm_c_eval_string' when calling 'main' procedure.
* Makefile.am (AM_CPPFLAGS): Define _GNU_SOURCE for 'asprintf'.
* build-aux/git-version-gen: New script.
* configure.ac (AC_INIT): Use it.
(AC_REQUIRE_AUX_FILE): Distribute it.
* Makefile.am (.version): New target.
(BUILT_SOURCES, EXTRA_DIST): Add it.
(dist-hook): Generate ".tarball-version".
* .gitignore: Update.
