m4_ifndef([m4_chomp_all], [m4_define([m4_chomp_all], [m4_format([[%.*s]], m4_bregexp(m4_translit([[$1]], [/], [/ ]), [/*$]), [$1])])])
m4_ifndef([m4_esyscmd_s], [m4_define([m4_esyscmd_s], [m4_chomp_all(m4_esyscmd([$1]))])])
dnl NUT version number is defined here, with a Git suffixed macro like
dnl NUT_VERSION_MACRO "2.7.4-2838+gdfc3ac08"
dnl defined separately in include/nut_version.h (generated by make)
dnl ...or not defined, for quicker rebuilds, depending on settings.
dnl Old hard-coded approach (mangled a bit):
dnl AC INIT([nut],[2.8.2.1],[https://github.com/networkupstools/nut/issues])
dnl Note: srcdir is only set after AC INIT has completed, but $0 points
dnl to the generated configure script which is part of dist tarball and
dnl should be at source root too.
dnl Note: this gets evaluated (script called) a lot of times during autoconf
dnl but ends up as static strings in the generated configure script. It may
dnl be beneficial to have a `version.m4` generated by `autogen.sh` and/or
dnl shipped in a tarball, allowing for a singular include into configure.ac
dnl See https://github.com/networkupstools/nut/issues/1949 for details.
dnl Oddly, autoconf-2.69 on CentOS 7 both complains that AC INIT argument
dnl is not a literal, and does contain expected values in the generated
dnl script and include/config.h. A "pure" m4 solution would be quieter.
AC_INIT([nut],
m4_esyscmd_s([NUT_VERSION_QUERY=VER50 "`dirname "$0"`/tools/gitlog2version.sh" 2>/dev/null]),
[https://github.com/networkupstools/nut/issues],[nut],
m4_esyscmd_s([NUT_VERSION_QUERY=URL "`dirname "$0"`/tools/gitlog2version.sh" 2>/dev/null]))
dnl See docs/maintainer-guide.txt about releases - updating the version
dnl above is a small part of the consistent ritual!
dnl PACKAGE_URL="https://www.networkupstools.org/" for development iterations
dnl or "https://www.networkupstools.org/historic/v1.2.3/index.html" for release
dnl snapshots further set in stone. Either way, there should be a slash and
dnl either a filename, or nothing. Adding a bogus filename and chopping it
dnl off by `dirname` should do the trick.
dnl NOTE: the resulting NUT_WEBSITE_BASE string does not end with a slash!
NUT_WEBSITE_BASE="`dirname "${PACKAGE_URL}index.html"`"
dnl Fallback, no trailing slash!
test -n "${NUT_WEBSITE_BASE-}" || NUT_WEBSITE_BASE='https://www.networkupstools.org'
dnl Note: this refers to GITREV at the time of configure script running
dnl primarily for better messaging in the script itself (also to render
dnl the PDF documentation revision history via docs/docinfo.xml.in).
dnl If the NUT codebase in this workspace is being developed and rebuilt
dnl without reconfiguration, detailed version in the binaries will differ
dnl (that one comes from the NUT_VERSION_MACRO from nut_version.h file).
dnl # Example: NUT_SOURCE_GITREV='2.8.2.695.1-696+g0e00f0777'
NUT_SOURCE_GITREV="`NUT_VERSION_QUERY=DESC50 "${srcdir}/tools/gitlog2version.sh" 2>/dev/null`"
dnl A true/false (literally) response that can be used for prettier messages
dnl emitted by NUT code.
NUT_SOURCE_GITREV_IS_RELEASE="`NUT_VERSION_QUERY=IS_RELEASE "${srcdir}/tools/gitlog2version.sh" 2>/dev/null || echo false`"
NUT_SOURCE_GITREV_IS_PRERELEASE="`NUT_VERSION_QUERY=IS_PRERELEASE "${srcdir}/tools/gitlog2version.sh" 2>/dev/null || echo false`"
AS_IF([$NUT_SOURCE_GITREV_IS_RELEASE], [NUT_SOURCE_GITREV_DEVREL="release"], [
AS_IF([$NUT_SOURCE_GITREV_IS_PRERELEASE], [NUT_SOURCE_GITREV_DEVREL="pre-release"],
[NUT_SOURCE_GITREV_DEVREL="development iteration"])
])
dnl Semantic version of most-recent NUT release this code is derived from.
dnl It may equal the NUT_SOURCE_GITREV and NUT_SOURCE_GITREV_NUMERIC, but
dnl this situation is only expected if NUT_SOURCE_GITREV_IS_RELEASE==true;
dnl for a pre-release it may differ from even the base NUT_VERSION numbers
dnl (e.g. a commit tagged as 2.8.3-rc5 can have its own NUT_VERSION based
dnl on 2.8.2-something, but is assumed as a pre-release for 2.8.3 SEMVER).
NUT_SOURCE_GITREV_SEMVER="`NUT_VERSION_QUERY=SEMVER "${srcdir}/tools/gitlog2version.sh" 2>/dev/null`"
dnl Gitrev-based build identifier which can be used for e.g. PyPI uploads:
dnl # Example: NUT_SOURCE_GITREV_NUMERIC='2.8.2.695.1.696'
dnl # NUT_SOURCE_GITREV_NUMERIC="`echo "${NUT_SOURCE_GITREV}" | sed -e 's/^v//' -e 's/@<:@+-@:>@g.*$//' -e 's/-/./g'`"
dnl # Without the commit-count since tag (dash-separated part):
dnl # Example: NUT_SOURCE_GITREV_NUMERIC='2.8.2.695.1'
NUT_SOURCE_GITREV_NUMERIC="`echo "${NUT_SOURCE_GITREV}" | sed -e 's/^v//' -e 's/@<:@+-@:>@g.*$//' -e 's/-@<:@0-9@:>@*$//'`"
dnl Note: except for experiments, do not pass this into config.h - use
dnl the NUT_VERSION_MACRO from nut_version.h instead. Developers may
dnl want to disable their "force-nut-version-header" configure option
dnl to reduce rebuild scope and so speed up the iterations with ccache.
dnl New "config.h" contents for every reconfig would defeat that purpose!
