This works great for running the tests + * against Closure-style generated code, but we also want to run the + * tests against CommonJS-style generated code without having to fork + * the tests. + * + * Closure-style imports import each individual type by name. This is + * very different than CommonJS imports which are by file. So we put + * special comments in these tests like: + * + * // CommonJS-LoadFromFile: test_pb + * goog.require('proto.jspb.test.CloneExtension'); + * goog.require('proto.jspb.test.Complex'); + * goog.require('proto.jspb.test.DefaultValues'); + * + * This script parses that special comment and uses it to generate proper + * CommonJS require() statements so that the tests can run and pass using + * CommonJS imports. */ var lineReader = require('readline').createInterface({ |
