NAME

vcs-snapshot.eclass - 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 github, 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.

 

EXAMPLE

EAPI=4
AUTOTOOLS_AUTORECONF=1
inherit autotools-utils vcs-snapshot

SRC_URI="http://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz"

and however the tarball was originally named, all files will appear in ${WORKDIR}/${P}.  

FUNCTIONS

vcs-snapshot_src_unpack
Extract all the archives from ${A}. The .tar, .tar.gz, .tar.bz2 and .tar.xz archives will be unpacked to directories matching their local names. Other archive types will be passed down to regular unpack.
