Access system enivronment variables cross-platform?

[keith-miller]

Hello, I was wondering if I can access system enivronment variables like $GOPATH/%GOPATH% in a Taskfile. I have a task that looks like this:

  generate-protos:
    deps:
      - create-models-dir
    cmds:
      - go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
      - go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
      - |
        protoc --plugin=protoc-gen-go={{if eq OS "windows"}}%GOPATH%{{else}}$GOPATH{{end}}/bin/protoc-gen-go \
        --proto_path=protos \
        --go_out=models \
        --go_opt=paths=source_relative
       ...

but this isn't working.

Thanks!

Finally figured out that I can do this:

generate-protos:
    deps:
      - create-models-dir
    cmds:
      - go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
      - go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
      - |
        protoc --plugin=protoc-gen-go={{.GOPATH}}{{fromSlash "/bin/protoc-gen-go"}}{{exeExt}} \
        --proto_path=protos \
        --go_out=models \
        --go_opt=paths=source_relative
       ...

Still has issues on Windows though, even though the path is correct

Duh, I needed quoted for the back slashes in the path lol

generate-protos:
    deps:
      - create-models-dir
    cmds:
      - go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
      - go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
      - |
        protoc --plugin=protoc-gen-go="{{.GOPATH}}{{fromSlash "/bin/protoc-gen-go"}}{{exeExt}}" \
        --proto_path=protos \
        --go_out=models \
        --go_opt=paths=source_relative
       ...

Works on MacOS and Windows now.
