For what it's worth, the author (sankho) mentions that he uses other editors for project-wide find and replace. This can be done in vim too (although I do not --- I'll return to this). You can check out the typically great vimcasts post on this: http://vimcasts.org/episodes/project-wide-find-and-replace/

For whatever reason, I find it easier to use commandline tools to do large search and replaces. I do embrace the vim-as-text-editor within the larger Linux-program-composability philosophy, but I understand that not everyone else does. So I use ack and perl, as mentioned in this StackOverflow post: http://stackoverflow.com/a/8744108/1141805

(Actually, sometimes I distinctly do things the wrong way. I open a scratch buffer, `:r! ls` to get my file names, restrict to those that I want, create a macro that does what I want on the file under the cursor, and then repeat the macro. I am not proud.)

Here's my find-and-replace command, copied from some StackOverflow answer at some point in time: https://github.com/tubbo/home/blob/master/bin/repl

It uses Ag to search over each file and Perl to perform the necessary regex. It also creates *.bak backup files in case I replaced something that wasn't supposed to be replaced, but will remove those backup files if I'm in a Git repo (because I basically had to `git clean -f` every time after using this command...so I just wrote it into the command)

It's possible to run a macro on a list of files? I usually just open the files one by one and @@:wq (oops)

Yes, it's quite possible:

  :args *.cpp  " or any other list of files
  :set autowrite
  :argdo normal @@
  :wq
