Protoc Gen API Linter

Currently early ALPHA, APIs can and will change

Wraps https://github.com/googleapis/api-linter as a protoc plugin.

Protosets for unit tests

If you add or change the protos in internal/apilinter/testdata do this to regenerate:

buf build internal/apilinter/testdata/ --output internal/apilinter/testdata/protos.bin

Using the API Linter plugin locally

First, you need to generate the binary:

$ go install ./cmd/protoc-gen-api-linter

$ protoc-gen-api-linter help
Usage of protoc-gen-api-linter:
  -config_path string
    	Set the filepath to the linter config
  -disable_rule value
    	Disable a rule with the given name.
    	May be specified multiple times.
  -enable_rule value
    	Enable a rule with the given name.
    	May be specified multiple times.
  -exit_on_error
    	Exit on first error (default true)
  -report_filename string
    	Set the filename of the JSON report (default "api_linter.json")
  -report_pretty_print
    	Pretty print JSON reports
  -version
    	Print version and exit.

buf.gen.yaml is configured in this repo to use the binary installed in $GOPATH/bin

Then run buf generate --debug -vv and you should see the following:

$ tree gen
gen
└── reports
    └── apilinter-report.json

Roadmap

• Expose base api-linter functionality
• Add support for enabling and disabling one or more rules
• Add optional non-zero exit behaviour to halt code-generation process
• Add verbose output option
• Add support for using a local config file
• Add to Buf BSR for remote code generation
• Add Goreleaser
