Method P

protoc-gen-go/generator/generator.go:1008–1042

P prints the arguments to the generated output. It handles strings and int32s, plus handling indirections because they may be *string, etc. Any inputs of type AnnotatedAtoms may emit annotations in a .meta file in addition to outputting the atoms themselves (if g.annotateCode is true).

(str ...interface{})

// annotations in a .meta file in addition to outputting the atoms themselves (if g.annotateCode
// is true).
