Created with contents that were learned at +# the last time autoconf was run, and used by git-version-gen. Must not +# be present in either $(srcdir) or $(builddir) for git-version-gen to +# give accurate answers during normal development with a checked out tree, +# but must be present in a tarball when there is no version control system. +# Therefore, it cannot be used in any dependencies. GNUmakefile has +# hooks to force a reconfigure at distribution time to get the value +# correct, without penalizing normal development with extra reconfigures. +# +# .version - present in a checked-out repository and in a distribution +# tarball. Usable in dependencies, particularly for files that don't +# want to depend on config.h but do want to track version changes. +# Delete this file prior to any autoconf run where you want to rebuild +# files to pick up a version string change; and leave it stale to +# minimize rebuild time after unrelated changes to configure sources. +# +# As with any generated file in a VC'd directory, you should add +# /.version to .gitignore, so that you don't accidentally commit it. +# .tarball-version is never generated in a VC'd directory, so needn't +# be listed there. +# +# Use the following line in your configure.ac, so that $(VERSION) will +# automatically be up-to-date each time configure is run (and note that +# since configure.ac no longer includes a version string, Makefile rules +# should not depend on configure.ac for version updates). +# +# AC_INIT([GNU project], +# m4_esyscmd([build-aux/git-version-gen .tarball-version]), +# [bug-project@example]) +# +# Then use the following lines in your Makefile.am, so that .version +# will be present for dependencies, and so that .version and +# .tarball-version will exist in distribution tarballs. +# +# EXTRA_DIST = $(top_srcdir)/.version +# BUILT_SOURCES = $(top_srcdir)/.version +# $(top_srcdir)/.version: +# echo '$(VERSION)' > $@-t +# mv $@-t $@ +# dist-hook: +# echo '$(VERSION)' > $(distdir)/.tarball-version + + +me=$0 + +year=`expr "$scriptversion" : '\([^-]*\)'` +version="git-version-gen $scriptversion + +Copyright (C) ${year} Free Software Foundation, Inc. +License GPLv3+: GNU GPL version 3 or later <https://gnu.org/licenses/gpl.html>. +This is free software: you are free to change and redistribute it. +There is NO WARRANTY, to the extent permitted by law." + +usage="\ +Usage: $me [OPTION]... \$srcdir/.tarball-version [TAG-NORMALIZATION-SED-SCRIPT] +Print a version string. + +Options: + + --prefix PREFIX prefix of git tags (default 'v') + --fallback VERSION + fallback version to use if \"git --version\" fails + + --help display this help and exit + --version output version information and exit + +Send patches and bug reports to <bug-gnulib@gnu.org>." + +prefix=v +fallback= + +while test $# -gt 0; do + case $1 in + --help) echo "$usage"; exit 0;; + --version) echo "$version"; exit 0;; + --prefix) shift; prefix=${1?};; + --fallback) shift; fallback=${1?};; + -*) + echo "$0: Unknown option '$1'." >&2 + echo "$0: Try '--help' for more information." >&2 + exit 1;; + *) + if test "x$tarball_version_file" = x; then + tarball_version_file="$1" + elif test "x$tag_sed_script" = x; then + tag_sed_script="$1" + else + echo "$0: extra non-option argument '$1'." >&2 + exit 1 + fi;; + esac + shift +done + +if test "x$tarball_version_file" = x; then + echo "$usage" + exit 1 +fi + +tag_sed_script="${tag_sed_script:-s/x/x/}" + +nl=' +' + +# Avoid meddling by environment variable of the same name. +v= +v_from_git= + +# First see if there is a tarball-only version file. +# then try "git describe", then default. +if test -f $tarball_version_file +then + v=`cat $tarball_version_file` || v= + case $v in + *$nl*) v= ;; # reject multi-line output + esac + test "x$v" = x \ + && echo "$0: WARNING: $tarball_version_file is damaged" 1>&2 +fi + +if test "x$v" != x +then + : # use $v +# Otherwise, if there is at least one git commit involving the working +# directory, and "git describe" output looks sensible, use that to +# derive a version string. +elif test "`git log -1 --pretty=format:x . 2>&1`" = x \ + && v=`git describe --abbrev=4 --match="$prefix*" HEAD 2>/dev/null \ + || git describe --abbrev=4 HEAD 2>/dev/null` \ + && v=`printf '%s\n' "$v" | sed "$tag_sed_script"` \ + && case $v in + $prefix[0-9]*) ;; + *) (exit 1) ;; + esac +then + # Is this a new git that lists number of commits since the last + # tag or the previous older version that did not? + # Newer: v6.10-77-g0f8faeb + # Older: v6.10-g0f8faeb + vprefix=`expr "X$v" : 'X\(.*\)-g[^-]*$'` || vprefix=$v + case $vprefix in + *-*) : git describe is probably okay three part flavor ;; + *) + : git describe is older two part flavor + # Recreate the number of commits and rewrite such that the + # result is the same as if we were using the newer version + # of git describe. + vtag=`echo "$v" | sed 's/-.*//'` + commit_list=`git rev-list "$vtag"..HEAD 2>/dev/null` \ + || { commit_list=failed; + echo "$0: WARNING: git rev-list failed" 1>&2; } + numcommits=`echo "$commit_list" | wc -l` + v=`echo "$v" | sed "s/\(.*\)-\(.*\)/\1-$numcommits-\2/"`; + test "$commit_list" = failed && v=UNKNOWN + ;; + esac + + # Change the penultimate "-" to ".", for version-comparing tools. + # Remove the "g" to save a byte. + v=`echo "$v" | sed 's/-\([^-]*\)-g\([^-]*\)$/.\1-\2/'`; + v_from_git=1 +elif test "x$fallback" = x || git --version >/dev/null 2>&1; then + v=UNKNOWN +else + v=$fallback +fi + +v=`echo "$v" |sed "s/^$prefix//"` + +# Test whether to append the "-dirty" suffix only if the version +# string we're using came from git.
