+# @BLURB: Eclass for building software written in the go |
22 |
+# programming language that uses go modules and does not vendor. |
23 |
+# @DESCRIPTION: |
24 |
+# This eclass provides a src_unpack function which supports vendoring |
25 |
+# dependencies for software written in the go programming language that |
26 |
+# uses go modules. |
27 |
+# |
28 |
+# You will know the software you are packaging uses modules because |
29 |
+# it will have files named go.sum and go.mod in its top-level source |
30 |
+# directory. If it does not have these files, use the golang-* eclasses. |
31 |
+# |
32 |
+# If there is also a directory named vendor in the top level source directory |
33 |
+# of your package, use the golang-module eclass instead of this one. |
34 |
+# |
35 |
+# This eclass provides a src_unpack function which unpacks the |
36 |
+# first tarball mentioned in SRC_URI to the usual location and unpacks |
37 |
+# any modules mentioned in EGO_VENDOR to ${S}/vendor. |
38 |
+# |
39 |
+# Please note that this eclass currently handles only tarballs |
40 |
+# (.tar.gz), but support for more formats may be added in the future. |
41 |
+# |
42 |
+# Since Go programs are statically linked, it is important that your ebuild's |
43 |
+# LICENSE= setting includes the licenses of all statically linked |
44 |
+# dependencies. So please make sure it is accurate. |
45 |
+# |
46 |
+# @EXAMPLE: |
47 |
+# |
48 |
+# @CODE |
49 |
+# EGO_VENDOR=( |
50 |
+# "github.com/xenolf/lego 6cac0ea7d8b28c889f709ec7fa92e92b82f490dd" |
51 |

57 |
+# ${EGO_VENDOR_URI}" |
58 |
+# @CODE |
