#!/bin/bash
### Description
#
# Return the version representing the state of the working directory.
#
# Expected output variants:
# - 2.3.1
# - 2.3.1-dirty
# - 2.3.1-146-COMMITID
# - 2.3.1-146-COMMITID-dirty
#
# The "-dirty" suffix is added whenever there are uncommitted changes in the
# working directory.
#
# The "-xxx-COMMITID" part is added whenever the currently checked out commit
# does not have an associated git tag. "xxx" represents the number of commits
# since the latest tag. "COMMITID" is a hash representing the current commit.
### Shell configuration and error handler
#
set -e
set -u
_fatalError() {
MSG="$1"
echo "ERROR($0): $MSG" 1>&2
exit 1
}
### Check the runtime environment
#
if [ ! -d dev-tools ]; then
_fatalError "This script must be run from the root of either git repository or uncompressed distribution package directory"
fi
### Define the help method
#
_showHelp()
{
cat <<EOF
Purpose:
Return the version of Snoopy code in the source tree
Supported CLI arguments:
-i Ignore a dirty working directory - do not add '-dirty' suffix to the version.
Only applicable in 'git' mode (and when 'autoreconf' mode uses git too).
-m MODE Specify the mode of operation ('git', 'changelog', or 'autoreconf' [default]).
Mode 'autoreconf' uses 'git' mode if available, and falls back on 'changelog'
mode (i.e. when used within a distribution tarball).
-h/--help Show this help.
Supported environment variables:
SNOOPY_RELEASE_VERSION_IGNORE_DIRTY
If set, dirty working tree is not reported as such in the returned version.
Useful for fixing up (refreshed) release tooling on-the-fly while releasing
a package.
Usage:
Get the software release version:
$0
Get the version that ignores the "-dirty" git tag:
$0 -i

### Parse the CLI arguments

?)
_fatalError "Unsupported argument: '-$OPTARG'. Run '$0 -h' to list supported arguments." $LINENO
;;
*)
_fatalError "Internal error (opt=$opt)" $LINENO
;;
esac

### Parse ENV arguments
#
if [ ! -z ${SNOOPY_RELEASE_VERSION_IGNORE_DIRTY+x} ]; then
echo "[$0] WARNING: Environment varible SNOOPY_RELEASE_VERSION_IGNORE_DIRTY set, ignoring potentially dirty working directory." 1>&2

### Check arguments
#

#### First get current commit
##
#CURRENT_COMMIT_HASH=`git rev-parse HEAD`
#
#
#
#### Check if current commit has corresponding tag
##
#if git show-ref --tags | grep "^$CURRENT_COMMIT_HASH refs/tags" > /dev/null; then
# CURRENT_TAG=`git show-ref --tags | grep "^$CURRENT_COMMIT_HASH refs/tags" | awk '{print $2}' | sed -e 's#^refs/tags##'`
# CURRENT_PACKAGE_VERSION=`echo "$CURRENT_TAG" | sed -e 's/snoopy-//'`
#
# ### Is tree dirty?
# #
# if git describe --tags --dirty | grep -- '-dirty$' > /dev/null; then
# CURRENT_PACKAGE_VERSION="${CURRENT_PACKAGE_VERSION}-dirty"
# fi
#else
# # Here '-dirty' gets appended automatically
# CURRENT_PACKAGE_VERSION=`git describe --tags --dirty`
#fi
### Get current Snoopy version from git, if applicable
#
# Used for building from git, and for making RC packages
#
if [ "$MODE" == "autoreconf" -o "$MODE" == "git" ]; then
if [ -d .git ]; then
if [ "$IGNORE_DIRTY" == "true" ]; then
SNOOPY_RELEASE_VERSION=`git describe --tags --always | sed -e 's/^snoopy-//'`
else
SNOOPY_RELEASE_VERSION=`git describe --tags --always --dirty | sed -e 's/^snoopy-//'`
fi
echo $SNOOPY_RELEASE_VERSION
exit 0
fi
fi
### Otherwise get it from ChangeLog
#
# Used only if ./bootstrap.sh is run from distribution package, not from git
#
if [ "$MODE" == "autoreconf" -o "$MODE" == "changelog" ]; then
if [ -f ChangeLog ]; then
SNOOPY_RELEASE_VERSION=`cat ChangeLog | grep -E '^[-0-9]+ - Version [0-9]+\.[0-9]+\.[0-9]+(rc[0-9]+)?$' | head -n1 | awk '{print $4}'`
echo $SNOOPY_RELEASE_VERSION
exit 0
fi
fi
### Signal error
#
_fatalError "Unable to determine Snoopy version (mode=$MODE)"
