Hi Remi,

At the moment there is only the both outputs and the arguments. So there seems to be no way to actually interact with a ToolProvider using the "run" method. Since there is no way to interact, the benefit is not given this way or am I wrong here? -Patrick

Hi Patrick, good question !

The Tool provider interface provide a non-interactive interface, so it's equivalent to calling jshell with some scripts as arguments and not with interacting with jshell on the console. So the input scripts are provided in the argument.

I think the module jdk.jshell should provide a java.util.spi.ToolProvider so i can embed jshell, like i can embed any dynmic langage runtimes, in my program instead of having to invoke it using the command line (without being able to control the exact version of jshell or even if jshell is present in case of a custom jdk image). regards, > Rémi
