Mention GOFLAGS in documentation as we don't have a -mod flag

[variadico]

This is more of a documentation ticket. This should probably make its way to the readme or some other document.

staticcheck will fail if you don't have git installed. This is because go list will "helpfully" try to install deps it thinks are missing.

The error looks like this:

$ staticcheck ./...
go [list -e -json -compiled -test=true -export=false -deps=true -find=false -tags= -- ./...]: exit status 1: go: github.com/lib/[email protected]: git init --bare in /root/go/pkg/mod/cache/vcs/01b4997f7dd5821a38fc67ad1dbddb0839f3fe66c76533286b350cb97434f24c: exec: "git": executable file not found in $PATH

If you use go build -mod vendor and have a vendor/ directory, then this will cause you problems. To make the -mod vendor setting global you have to set GOFLAGS.

export GOFLAGS="-mod=vendor"

Then staticcheck will work.

Noted, we'll mention GOFLAGS in the docs.

See also golang/go#27227 and golang/go#30240

GOFLAGS also helps to be able to specify -modfile

GOFLAGS="-mod=mod -modfile=go_test.mod" staticcheck

Is GOFLAGS="-mod=vendor" still required since Go 1.14, which added autodetection of vendoring? https://go.dev/doc/go1.14#vendor

[wallyqs]

If you want to use GOFLAGS="-modfile=go_test.mod" for example, yes would be required.
