# This file implements dep (https://github.com/golang/dep) support in pkgsrc.

|
# GO_DEPS
|
|
# This is a list of dependencies of the format url:sha[:dir]. These
|
|
# dependencies can be generated using the print-go-deps helper target
|
|
# against an extracted WRKSRC, which parses the Godeps file contained in
|
|
# the source that would normally be used by dep.
|
|
#
|
|
# Currently only GitHub URLs are supported, so if a Godeps dependency
|
|
# uses a different URL, the equivalent GitHub URL needs to be calculated
|
|
# and the original URL added as the optional :dir argument. This file
|
|
# contains a list of GODEP_REDIRECTS which translates common redirects,
|
|
# and additions to this list are encouraged.
|
|
#
|
|
# The print-go-deps target will reduce SHA strings to the first 8
|
|
# characters to avoid long lines, but the extracted archive will use the
|
|
# full SHA.
|
|
#
|
|
# Examples:
|
|
# github.com/golang/protobuf:92554152
|
|
# github.com/collectd/go-collectd:2ce14454:collectd.org
|
|
# github.com/uber-go/atomic:8474b86a:go.uber.org/atomic

#
|
|
# GODEP_REDIRECTS
|
|
# Maps a URL or subset of a URL to its GitHub equivalent. URLs that are
|
|
# likely to be used across multiple packages should be added to this
|
|
# file, otherwise add them to the individual package Makefile.
|
|
#
|
|
# Examples:
|
|
# collectd.org=github.com/collectd/go-collectd
|
|
# golang.org/x=github.com/golang
