• CodeIgniter - accessing $config variable in view

  Pretty often I need to access config variables in views. I know I can pass them from controller to load-view(). But it seems excessive to do it explicitly. Is there some way or trick to access $config variable from CI views without disturbing controllers with spare code?

• Use the keyword class as a variable name in C++

  - by Leif Andersen

  I am having trouble writing C++ code that uses a header file designed for a C file. In particular, the header file used a variable name called class: int BPY_class_validate(const char *class_type, PyObject *class, PyObject *base_class, BPY_class_attr_check* class_attrs, PyObject **py_class_attrs); This works in C as class isn't taken as a keyword, but in C++, class is. So is there anyway I can #include this header file into a c++ file, or am I out of luck? Thank you.

• What is the '@(' doing in this Perl code?

  - by Anthony Veckey

  In this code snippet: use strict; use warnings; use Data::Dumper; my $r = [qw(testing this thing)]; print Dumper($r); foreach my $row (@({$r}) { print "$row\n"; $row .= 'mod'; } print Dumper($r); print Dumper(@({$r}); I figured out that the '(' after the '@' in the foreach is causing this not to loop correctly. I have no idea why this code even works as there is no ending parenthesis. What is this doing? It looks to be creating a new variable on the fly, but shouldn't 'use strict' have fired or something? Please help explain what that '@(' is doing and why it still runs without an ending parenthesis.
