Editing SimTX API/Schema (section)

== Generating bindings ==
Save the files under a directory <code>simtx/v25/</code>, because they import each other by that path, and run <code>protoc</code> from the directory above it. For example, for Python:

<syntaxhighlight lang="bash">
protoc -I . --python_out=. simtx/v25/common.proto simtx/v25/session.proto simtx/v25/control.proto simtx/v25/frames.proto
</syntaxhighlight>

Any protobuf 3 toolchain works. Read and write frames with the library's length-delimited helpers, after the 8-byte [[SimTX API/Framing#Preface|preface]]. A minimal hand-written codec is shown on [[SimTX API/Quick start]].
