Hot reload?

[tonijota]

It is possible to do some kind of hot reloading with Jint (3)?

Currently I think state cannot be kept between such source code refresh, new Engine instance with new scripts executed into it.

I have an question related to this also. Its safe multiple instances of new Engine for per-script isolated environment?

For example i'm creating an plugin/module based system, that means each script will have two global functions OnInit and OnShutdown for instanting and cleanup their data, by script. Currently i'm using per engine instance to do this.

I'm using same technique like Lua Script State Lifetime, you have per script lua_State* then assign all global stuff for each lua_State* pointer.

It's ok about memory conditions?

Engine instances share very little information, basically just static information that doesn't change, like runtime type information.

Engine instance are also lazy by nature so they shouldn't allocate that many things when created to run simple small scripts.

You probably need to test and benchmark that your expectations are met.
