| # @BLURB: support eclass for unpacking VCS snapshot tarballs for |
| # software written in the Go programming language |
| # @DESCRIPTION: |
| # This eclass provides a convenience src_unpack() which unpacks the |
| # first tarball mentioned in SRC_URI to its appropriate location in |
| # ${WORKDIR}/${P}, treating ${WORKDIR}/${P} as a go workspace. |
| # |
| # The location where the tarball is extracted is defined as |
| # ${WORKDIR}/${P}/src/${EGO_PN}. |
| # |
| # The typical use case is VCS snapshots coming from github, bitbucket |
| # and similar services. |
| # |
| # Please note that this eclass currently handles only tarballs |
| # (.tar.gz), but support for more formats may be added in the future. |
| # |
| # @EXAMPLE: |
| # |
| # @CODE |
| # EGO_PN=github.com/user/package |
| # inherit golang-vcs-snapshot |
| # |
| # SRC_URI="http://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz" |
| # @CODE |
| # |
| # The above example will extract the tarball to |
| # ${WORKDIR}/${P}/src/github.com/user/package |
