# gitpkgv.bbclass provides a GITPKGV and GITPKGVTAG variables to be
# used in PKGV, as described bellow:
#
# - GITPKGV which is a sortable version with the format NN+GITHASH, to
# be used in PKGV, where
#
# NN equals the total number of revs up to SRCREV
# GITHASH is SRCREV's (full) hash
#
# - GITPKGVTAG which is the output of 'git describe --tags --exact-match'
# allowing for automatic versioning
#
# gitpkgv.bbclass assumes the git repository has been cloned, and
# contains SRCREV. So ${GITPKGV} and ${GITPKGVTAG} should never be
# used in PV, only in PKGV. It can handle SRCREV = ${AUTOREV}, as
# well as SRCREV = "<some fixed git hash>".
#
# WARNING: if upstream repository is always using consistent and
# sortable tag name scheme you can get sortable version including tag
# name with ${GITPKGVTAG}, but be aware that ie tag sequence "v1.0,
# v1.2, xtest, v2.0" will force you to increment PE to get upgradeable
# path to v2.0 revisions
#
# use example:
#
# inherit gitpkgv
#
# PV = "1.0+gitr${SRCPV}" # expands to something like 1.0+gitr3+4c1c21d7dbbf93b0df336994524313dfe0d4963b
# PKGV = "1.0+gitr${GITPKGV}" # expands also to something like 1.0+gitr31337+4c1c21d7d
#
# or
#
# inherit gitpkgv
#
# PV = "1.0+gitr${SRCPV}" # expands to something like 1.0+gitr3+4c1c21d7dbbf93b0df336994524313dfe0d4963b
# PKGV = "${GITPKGVTAG}" # expands to something like 1.0-31337+g4c1c21d
# if there is tag v1.0 before this revision or
# ver1.0-31337+g4c1c21d if there is tag ver1.0
GITPKGV = "${@get_git_pkgv(d, False)}"
GITPKGVTAG = "${@get_git_pkgv(d, True)}"
# This regexp is used to drop unwanted parts of the found tags. Any matching
# groups will be concatenated to yield the final version.
