One aspect of this project which is surprisingly difficult is standard output. Julia provides a handy redirect_stdio method for this, but there are a number of shortcomings. This is what is currently used to get the standard output from a Cell in Olive.
The only way to write this output into memory is to use a Pipe.
redirecting the output in this way duplicates stream descriptors -- throwing an error if more than one is opened at a time.
proposed solution
The solution to this, hopefully, will rely on the mutation of the new olive_module bare modules. These modules will remove println(a::Any) = println(stdout, a::Any ...) and replace it with println(a::Any ...) = println(ourbuffer, a ...)
Basically, we are going to change the Methods inside of Base to facilitate this rather than redirecting our output.
