1# gitpkgv.bbclass provides a GITPKGV and GITPKGVTAG variables to be 2# used in PKGV, as described bellow: 3# 4# - GITPKGV which is a sortable version with the format NN+GITHASH, to 5# be used in PKGV, where 6# 7# NN equals the total number of revs up to SRCREV 8# GITHASH is SRCREV's (full) hash 9# 10# - GITPKGVTAG which is the output of 'git describe --tags --exact-match' 11# allowing for automatic versioning 12# 13# gitpkgv.bbclass assumes the git repository has been cloned, and 14# contains SRCREV. So ${GITPKGV} and ${GITPKGVTAG} should never be 15# used in PV, only in PKGV. It can handle SRCREV = ${AUTOREV}, as 16# well as SRCREV = "<some fixed git hash>". 17# 18# WARNING: if upstream repository is always using consistent and 19# sortable tag name scheme you can get sortable version including tag 20# name with ${GITPKGVTAG}, but be aware that ie tag sequence "v1.0, 21# v1.2, xtest, v2.0" will force you to increment PE to get upgradeable 22# path to v2.0 revisions 23# 24# use example: 25# 26# inherit gitpkgv 27# 28# PV = "1.0+gitr${SRCPV}" # expands to something like 1.0+gitr3+4c1c21d7dbbf93b0df336994524313dfe0d4963b 29# PKGV = "1.0+gitr${GITPKGV}" # expands also to something like 1.0+gitr31337+4c1c21d7d 30# 31# or 32# 33# inherit gitpkgv 34# 35# PV = "1.0+gitr${SRCPV}" # expands to something like 1.0+gitr3+4c1c21d7dbbf93b0df336994524313dfe0d4963b 36# PKGV = "${GITPKGVTAG}" # expands to something like 1.0-31337+g4c1c21d 37# if there is tag v1.0 before this revision or 38# ver1.0-31337+g4c1c21d if there is tag ver1.0 39 40GITPKGV = "${@get_git_pkgv(d, False)}" 41GITPKGVTAG = "${@get_git_pkgv(d, True)}" 42 43# This regexp is used to drop unwanted parts of the found tags.
