So I'm looking to have helm swoop look at all files in a project, not just the current set of open buffers.

This is so I can use swoop to find all occurrences in a project, mark relevant ones, then edit them (in helm swoops edit mode).

I feel that there's probably a clean way to do this with Helm/Helm swoop but here's my attempt to think through a solution:

1. gather filenames from projectile
2. create a list of buffers from the filename list
3. do the same routine as helm-multi-swoop-all besides using this new buffer list

(projectile-current-project-files), looks like it gives me the file list I'm looking for.

So helm-multi-swoop-all, looks like it'd be fairly easy to copy and then tweak.

(defun helm-multi-swoop-all (&optional $query)
  (interactive)
  "Apply all buffers to helm-multi-swoop"
  (cond ($query
         (setq helm-multi-swoop-query $query))
        (mark-active
         (let (($st (buffer-substring-no-properties
                     (region-beginning) (region-end))))
           (if (string-match "\n" $st)
               (message "Multi line region is not allowed")
             (setq helm-multi-swoop-query
                   (helm-swoop-pre-input-optimize $st)))))
        ((setq helm-multi-swoop-query
               (helm-swoop-pre-input-optimize
                (funcall helm-swoop-pre-input-function))))
        (t (setq helm-multi-swoop-query "")))
  (helm-multi-swoop--exec nil
                          :$query helm-multi-swoop-query
                          :$buflist (helm-multi-swoop--get-buffer-list)))

Just replace the call to helm-multi-swoop--get-buffer-list, to one that provided a list of buffers using projectiles list.

But now I'm a little stuck. I'm not sure how to create a list of buffers to feed into helm-swoop from a set of file names.

I also can't help but think there's a simpler way to achieve this, maybe without custom functions.
