goc

goc is a go command-line tool wrapper that injects code-coverage instrumentation into generated code. It instruments the compiled code using the standard Go toolchain command, and adds boilerplate code that allows collection of the coverage data through Ctrlz.

goc mimics go and is meant to be a transparent utility. For all commands, except build, it will silently call go internally, as-is, passing all the command-line parameters and environment variables. For build command, it will copy and create and instrumented version of the code, before using the supplied command-line parametes and environment variables to invoke go build on the instrumented code.
