Environments and lua_Reader cannot be used together

[MehradN]

The problem:

Currently (in sol2 version 3.3.0) there is no way to use sol::environment and lua_Reader together. sol::state::safe_script doesn't have an overload that can accept both, and sol::set_environment doesn't accept sol::load_result.

Why I have this problem:

I'm using Sol in an environment that I can't make any assumptions about the provided scripts. I'm planning to utilize sol::environment to prevent scripts from calling potentially dangerous functions that are provided by the Lua libraries. I can't be sure that the loaded scripts are small enough to fit in the ram, so loading all of the script to a std::string is not a viable option, and I might need to load scripts from non-conventional sources in the future, so loading the script using sol::state::safe_script_file is not a viable option either. So my only option is to use lua_Reader.

Possible solutions

• Adding an overload to sol::state::(safe_)script that accepts lua_Reader and sol::environment at the same time.
• Allowing sol::environment::set_on and sol::set_environment to accept sol::load_result.
