I am switching to Emacs from TextMate. One feature of TextMate that I would really like to have in Emacs is the "Find in Project" search box that uses fuzzy matching. Emacs sort of has this with ido, but ido does not search recursively through child directories. It searches only within one directory.

Is there a way to give ido a root directory and to search everything under it?

Update:

The questions below pertain to find-file-in-project.el from Michal Marczyk's answer.

If anything in this message sounds obvious it's because I have used Emacs for less than one week. :-)

As I understand it, project-local-variables lets me define things in a .emacs-project file that I keep in my project root.

How do I point find-file-in-project to my project root?

I am not familiar with regex syntax in Emacs Lisp. The default value for ffip-regexp is:

".*\\.\\(rb\\|js\\|css\\|yml\\|yaml\\|rhtml\\|erb\\|html\\|el\\)"

I presume that I can just switch the extensions to the ones appropriate for my project.

Could you explain the ffip-find-options? From the file:

(defvar ffip-find-options "" "Extra options to pass to `find' when using find-file-in-project.

Use this to exclude portions of your project: \"-not -regex \\".vendor.\\"\"")

What does this mean exactly and how do I use it to exclude files/directories?

Could you share an example .emacs-project file?
