Question

I’m trying to add a print statement to all functions in a python script (the programming language shouldn’t matter here though) using vim. Basically I want to change this:

def func1(a, b):
    pass

into this:

def func1(a, b):
    print 'in func1'
    pass

I was thinking of something like :g/\vdef (\w+)\(/CMD , but my vim skills are not yet good enough to come up with CMD. Does anyone know what I could use?

Thanks!

You can use whatever you’ve used to do this job by yourself, prefixed with :normal!:

g/\vdef\ (\w+)\(/exe "normal!^wywoprint 'in \<C-r>0'"

(note: according to the help, you must escape space when using \v:

Use of “\v” means that in the pattern after it all ASCII characters except
‘0’-‘9’, ‘a’-‘z’, ‘A’-‘Z’ and ‘_’ have a special meaning. “very magic”

. You see, space is not listed here.)
