8 mgorny 1.4 # @BLURB: support eclass for unpacking VCS snapshot tarballs
9 mgorny 1.1 # @DESCRIPTION:
10 mgorny 1.4 # This eclass provides a convenience src_unpack() which does unpack all
11     # the tarballs in SRC_URI to locations matching their (local) names,
12     # discarding the original parent directory.
13     #
14     # The typical use case are VCS snapshots, coming from github, bitbucket
15     # and similar services. They have hash appended to the directory name
16     # which makes extracting them a painful experience. But if you just use
17     # a SRC_URI arrow to rename it (which you're likely have to do anyway),
18     # vcs-snapshot will just extract it into a matching directory.
19     #
20     # Please note that this eclass handles only tarballs (.tar, .tar.gz,
21     # .tar.bz2 & .tar.xz). For any other file format (or suffix) it will
22     # fall back to regular unpack. Support for additional formats may be
23     # added at some point so please keep your SRC_URIs clean.
24     #
25 mgorny 1.1 # @EXAMPLE:
26     #
27     # @CODE
28     # EAPI=4
29     # AUTOTOOLS_AUTORECONF=1
30     # inherit autotools-utils vcs-snapshot
31     #
32     # SRC_URI="http://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz"
33     # @CODE
34 mgorny 1.4 #
35     # and however the tarball was originally named, all files will appear
36     # in ${WORKDIR}/${P}.
