Keep stack between eval

[sasq64]

I am implementing a REPL and want to keep local variables between calls to eval. I've looked at mirb and tried to do what it does, but I get a crash, maybe because I'm initiating the call from ruby instead of C, so I guess I call vm exec recursively ?

I also looked at eval.c but it's more complex (maybe because it needs to work when called from ruby).

Any help appreciated.

Show me the code, please.

Probably you can use mruby-binding gem (#5362, #5491).

b = binding
b.eval "a=12"
b.eval "p a"     # => 12

Don't forget to include mruby-binding gem when build.

Is the binding gem tested? I get very weird bugs when I use it. When assigning variables they sometimes end up containing different objects from random places?

Oh, it seems that it was a bug that was recently fixed; I pulled latest and now it seems to work :)

binding of course! Thank you.
