Say I have a Lua program that accepts user input which happens to be valid Lua source code. This is sanitized, compiled and executed while the program is still running. Is (or will) such a thing (be) possible with Go?
I have an idea on how you could accomplish that, but you would pretty much have to do the same in C.
Go is a compiled language, so in order to achieve what you would like to accomplish you would need to write a wrapper over CSP that would support versioning of the binary and export functionality over some kind of a RPC. The steps would be as following:
Obviously this is ridiculously complicated and you'll end up saving a lot of time using a scripting language through something like Otto or go-lua.
I think that the following two projects have enough meat between them to help me achieve what I want. Neither is a perfect drop-in replacement but both can be extended to deliver a service that is close enough to what I originally did with dynamic compilation in Lua.
