Power Assert instrumentor from code to code, with SourceMap.
espower-source is a source code transformer that applies espower to target code.
espower manipulates assertion expression in the form of ECMAScript AST defined in The ESTree Spec (formerly known as Mozilla SpiderMonkey Parser API), to instrument power-assert feature into the code. SourceMap information is appended in SourceMap Comment syntax at the end of returned code.
Pull-requests, issue reports and patches are always welcomed. See power-assert project for more documentation.
