# https://golang.org/issue/45979: after 'go get' on a package,
# that package should be importable without error.


# We start out with an unresolved dependency.
# 'go list' suggests that we run 'go get' on that dependency.

! go list -deps .
stderr '^m.go:3:8: no required module provides package rsc\.io/quote; to add it:\n\tgo get rsc.io/quote$'


# When we run the suggested 'go get' command, the new dependency can be used
# immediately.
#
# 'go get' marks the new dependency as 'indirect', because it doesn't scan
# enough source code to know whether it is direct, and it is easier and less
# invasive to remove an incorrect indirect mark (e.g. using 'go get') than to
# add one that is missing ('go mod tidy' or 'go mod vendor').

go get rsc.io/quote

! grep 'rsc.io/quote v\d+\.\d+\.\d+$' go.mod
