I can't get this simple LLDB alias to work
问题 I want to create an LLDB alias ps, such that ps foo becomes print [self foo] I've been watching the LLDB talk (WWDC session 321 on iTunes), and based on that, it looks like the alias to do that should be this one: command alias ps print [ self %1 ] but it doesn't work. Here I've given my app delegate a simple "count" method that returns an integer: (lldb) command alias ps print [ self %1 ] (lldb) ps count error: invalid operands to binary expression ('AppDelegate *' and 'int') error: 1 errors
