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' allowing for | ||
11 | # 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 | # | ||

36 | # PKGV = "${GITPKGVTAG}" # expands to something like 1.0-31337+g4c1c21d | ||
37 | # if there is tag v1.0 before this revision or | ||
