Hello, I wrote the previous mail on the phone by memory, sorry. I meant i'm using cl_safe_eval, which you understood correctly.
I understand that cl_safe_eval(form, env, value) is just a macro to si_safe_eval(3,form,env,value), so i tried si_save_eval(2, c_string_to_obj(_expr), Cnil) as per your suggestion and it works like a charm. This is great for faster development! Many thanks Daniel, Diogo On 8 December 2015 at 06:34, Daniel Kochmański <dan...@turtleware.eu> wrote: > Hello, > > do you mean si_safe_eval?
