| # @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 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: |
| # |
| # @CODE |
| # EAPI=4 |
| # AUTOTOOLS_AUTORECONF=1 |
| # inherit autotools-utils vcs-snapshot |
| # |
| # SRC_URI="http://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz" |
| # @CODE |
| # |
| # and however the tarball was originally named, all files will appear |
| # in ${WORKDIR}/${P}. |
