A context contains enough (error) information to determine precisely what just happened, eg:
code = "a = 1\n"& "b = 2/0\n"& "c = 3" context = string_exec(context,code)
Somewhere in context (I am implying the above is not the first time it is used), there should now be one of:
- line 1, variable a has not been defined
What if variable a was declared in the program already?
In the caller of string_exec() you mean? In that case, IIUC petelomax correctly, it wouldn't make a difference in his implementation, since the context is still different - so you'd still get that error since variable a was declared in the wrong context.
And what if
atom b = 9 b += 1would b now be accessable to the program that called the string_exec()?
No, not in petelomax's implementation, because the context is different.
Edit: well, not directly of course. You probably would be able to do something like "set_string_exec_variable(context, "b", 10)" or "get_string_exec_variable(context, "b")" though.
