Question

I have a very useful macro defined in .gdbinit

define rc
call (int)[$arg0 retainCount]
end

Is there anyway to define the same macro for lldb ?

Answer 1

You can do that with the following command definition in lldb:

command regex rc 's/(.+)/print (int)[%1 retainCount]/'

Example:

(lldb) rc indexPath
print (int)[indexPath retainCount]
(int) $2 = 2

You can put that into ~/.lldbinit (and restart Xcode).

One should think that something like

command alias rc print (int)[%1 retainCount]

should work, but as explained in I can't get this simple LLDB alias to work the %1 expansion does not work with expression, and command regex is a workaround.
