# @BLURB: support eclass for unpacking VCS snapshot tarballs
|
|
# @DESCRIPTION:
|
|
# This eclass provides a convenience src_unpack() which does unpack all
|
|
# the tarballs in SRC_URI to locations matching their (local) names,
|
|
# discarding the original parent directory.
|
|
#
|
|
# The typical use case are VCS snapshots, coming from bitbucket
|
|
# and similar services. They have hash appended to the directory name
|
|
# which makes extracting them a painful experience. But if you just use
|
|
# a SRC_URI arrow to rename it (which you're likely have to do anyway),
|
|
# vcs-snapshot will just extract it into a matching directory.
|
|
#
|
|
# Please note that this eclass handles only tarballs (.tar, .tar.gz,
|
|
# .tar.bz2 & .tar.xz). For any other file format (or suffix) it will
|
|
# fall back to regular unpack. Support for additional formats may be
|
|
# added at some point so please keep your SRC_URIs clean.
|
|
#
|
|
# Note: this eclass is no longer needed with the new-style 'archive'
|
|
# GitHub URLs. They have sane directory names and stable contents,
|
|
# so you should really prefer them.
|
|
#
|
|
# @EXAMPLE:
|
|
#
|
|
# @CODE
|
|
# EAPI=6
|
|
# inherit vcs-snapshot
|
|
#
|
|
# SRC_URI="https://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz
|
|
# https://github.com/example/${PN}-otherstuff/tarball/v${PV} -> ${P}-otherstuff.tar.gz"
|
|
# @CODE
|
|
#
|
|
# and however the tarballs were originally packed, all files will appear
|
|
# in ${WORKDIR}/${P} and ${WORKDIR}/${P}-otherstuff respectively.
