protoc-gen-go-cli

Generate command line interfaces to your gRPC services.

How to

Step 1: Install the plugin

$ GOBIN=$PWD/build go install go.einride.tech/protoc-gen-go-cli

Step 2: Configure the code generator

The following example uses a buf generate template to configure the CLI generator.

buf.gen.example.yaml:

version: v1

managed:
  enabled: true
  go_package_prefix:
    default: go.einride.tech/protoc-gen-go-cli/proto/cmd/examplectl
    except:
      - buf.build/googleapis/googleapis

plugins:
  # The CLI generator requires the stubs generated by protoc-gen-go.
  - name: go
    out: cmd/examplectl
    opt: module=go.einride.tech/protoc-gen-go-cli/proto/cmd/examplectl
    path: ./build/protoc-gen-go

  # The CLI generator also requires the stubs generated by protoc-gen-go-grpc.
  - name: go-grpc
    out: cmd/examplectl
    opt: module=go.einride.tech/protoc-gen-go-cli/proto/cmd/examplectl
    path: ./build/protoc-gen-go-grpc

  # The CLI generator optionally generates a root command and a main file
  # to the root of the output module.
  - name: go-cli
    out: cmd/examplectl
    strategy: all
    opt:
      - module=go.einride.tech/protoc-gen-go-cli/proto/cmd/examplectl
      - root=examplectl
      - main=true
      - gcloud_identity_tokens=true
    path: ./build/protoc-gen-go-cli

Step 3: Generate the code

$ buf generate buf.build/einride/aip \
  --template buf.gen.example.yaml \
  --path einride/example/freight

Step 4: Install the CLI

$ go install ./cmd/examplectl

Step 5: Use the CLI

$ examplectl help freight

this api represents a simple freight service

  examplectl freight [command]

  batch-get-sites batch get sites
