local_variable_get(p1)

public

Returns the value of the local variable symbol.

def foo
  a = 1
  binding.local_variable_get(:a) #=> 1
  binding.local_variable_get(:b) #=> NameError
end

This method is the short version of the following code:

binding.eval("#{symbol}")

static VALUE
bind_local_variable_get(VALUE bindval, VALUE sym)
{
    ID lid = check_local_id(bindval, &sym);
    const rb_binding_t *bind;
    const VALUE *ptr;

    if (!lid) goto undefined;

    GetBindingPtr(bindval, bind);

    if ((ptr = get_local_variable_ptr(bind->env, lid)) == NULL) {
      undefined:
        rb_name_error_str(sym, "local variable `%"PRIsVALUE"' not defined for %"PRIsVALUE,
                          sym, bindval);
    }

    return *ptr;
}
