<h1><a id="user-content-migrate-to-buf-from-prototool" class="anchor" aria-hidden="true" href="#migrate-to-buf-from-prototool"><span aria-hidden="true" class="octicon octicon-link"></span></a>Migrate to <code>buf</code> from <code>prototool</code>
|
|
</h1>
|
|
<p>Why? Because <code>prototool</code> is outdated, and can not run on M1 mac.</p>
|
|
<p>We need 3 files:</p>
|
|
<ul>
|
|
<li>
|
|
<code>build.go</code>: need to install protoc-gen-* binaries with pin version in <code>go.mod</code>
|
|
</li>
|
|
<li><code>buf.yaml</code></li>
|
|
<li><code>buf.gen.yaml</code></li>
|
|
</ul>
|
|
<p>FYI, the libs version I use:</p>
|
|
<ul>
|
|
<li><a href="https://github.com/golang/protobuf/releases/tag/v1.5.2">golang/protobuf v1.5.2</a></li>
|
|
<li><a href="https://github.com/grpc-ecosystem/grpc-gateway/releases/tag/v1.16.0">grpc-ecosystem/grpc-gateway v1.16.0</a></li>

<p>Run <code>make gen</code> to have fun of course.</p>

<h2><a id="user-content-faq" class="anchor" aria-hidden="true" href="#faq"><span aria-hidden="true" class="octicon octicon-link"></span></a>FAQ</h2>
|
|
<p>Remember <code>grpc-ecosystem/grpc-gateway</code>, <code>envoyproxy/protoc-gen-validate</code>, <code>kei2100/protoc-gen-marshal-zap</code> is optional, so feel free to delete if you don't use theme.</p>
|
|
<p>If use <code>vendor</code>:</p>
|
|
<ul>
|
|
<li>Replace <code>buf generate</code> with <code>buf generate --exclude-path vendor</code>.</li>
|
|
<li>Replace <code>buf format -w</code> with <code>buf format -w --exclude-path vendor</code>.</li>
|
|
</ul>
|
|
<p>If you use grpc-gateway:</p>
|
|
<ul>
|
|
<li>Replace <code>import "third_party/googleapis/google/api/annotations.proto";</code> with <code>import "google/api/annotations.proto";</code>
|
|
</li>
|
|
<li>Delete <code>security_definitions</code>, <code>security</code>, in <code>option (grpc.gateway.protoc_gen_swagger.options.openapiv2_swagger)</code>.</li>
|
|
</ul>
|
|
<p>The last step is delete <code>prototool.yaml</code>.</p>
|
|
<p>If you are not migrate but start from scratch:</p>
|
|
<ul>
|
|
<li>Add <code>buf lint</code> to make sure your proto is good.</li>
|
|
<li>Add <code>buf breaking --against "https://your-grpc-repo-goes-here.git"</code> to make sure each time you update proto, you don't break backward compatibility.</li>
|
|
</ul>
