# Extending Emacs rgrep for Org Mode Only Search

## 2019/05/23

I recently wanted to extend emacs rgrep to search within org files only. Here is what I came up with:

(defun jc/rgrep-org (regexp dir)
"rgrep for org files only"
(interactive
(progn
(grep-compute-defaults)

Note that in order to get this jc/rgrep-org function to work, I had to study and borrow from the internals of rgrep. In particular, the interactive form was most inspired from studying grep.el.gz.
M-x find-function rgrep for more details.
