* Introduction
~ivy-quick-find-files.el~ is a utility package for all of you out there
that often find themselves looking for the right file in the right
place, but you can’t be bothered to have a specific keybinding for
that particular file for one reason or another.

Now, you have a utility for finding files by directory with an
associated extension! Let’s say you often open files with a ~.org~
extension from your directory =~/org/=, this package will try to find it
insantly for you!

* Motivation
I often find myself opening a specific set of files, but they are too
numerous to make each one of them a keybinding. Well, I actually
could, but I end up with way too much for my taste. In fact, at the
time I’m writing this, I would have to manage a hundred keybindings
for my various org files alone! Unmanageable!

* Installation
** Prerequisites
First of all, make sure either ~find~ (which is fairly standard, it
should be there by default) or [[https://github.com/sharkdp/fd][fd]] are installed on your system, as
this package relies on one or the other depending on your choices
(~find~ by default).

** Local installation
The vanilla way of installing this package would be to clone this
repository somewhere in your Emacs’ ~load-path~, or add the following
line to your ~.emacs~ or ~init.el~:
#+begin_src emacs-lisp
  (add-to-list 'load-path "/path/to/ivy-quick-find-files.el")
#+end_src

Then add the following lines to your ~.emacs~ or ~init.el~:
#+begin_src emacs-lisp
  (require 'ivy-quick-find-files)
#+end_src

** Straight + use-package
My personnal choice in terms of installing packages is using straight
with use-package. If you are using it too, add the following code to
your ~.emacs~ or ~init.el~:
#+begin_src emacs-lisp
  (use-package ivy-quick-find-files
    :defer t
    :ensure t
    :straight (ivy-quick-find-files :type git
                                    :host github
                                    :repo "Phundrak/ivy-quick-find-files.el")
    :config ; Depending on your preferences of course
    (setq ivy-quick-find-files-program 'fd
          ivy-quick-find-files-dirs-and-exts '(("~/org" . "org"))))
#+end_src

** Other methods
I am aware other methods are available for installing packages in
Emacs, such as ~quelpa~ or Spacemacs’ and DoomEmacs’ package managers,
however I am yet unsure how to install this package with them. If you
do, feel free to submit a PR with new instructions!

* Customizing
A couple of variables can be editer by the user in order to configure
~ivy-quick-find-files.el~:
- ~ivy-quick-find-files-program~ :: The program to use in order to find
  your files. The two currently supported options are ~'find~ and ~'fd~.
- ~ivy-quick-find-files-fd-executable~ :: Specify the executable to use
  when using the option ~'fd~.
- ~ivy-quick-find-files-find-executable~ :: Specify the executable to
  use when using the option ~'find~.
- ~ivy-quick-find-files-dirs-and-exts~ :: List of pairs between
  directories and extensions. For one directory, the program will be
  searching recursively all files with the specified
  extension. Possible value:
  #+begin_src emacs-lisp
    '(("~/org" . "org")
      ("/tmp" . "html")
      ("~/code/C" . "h"))
  #+end_src
  This specific example will recursively search for all ~.org~ files in
  =~/org=, all ~.html~ files in ~/tmp~, and all ~.h~ files in =~/code/C=.

* I don’t want to use Ivy, I want to use <insert ivy alternative here>
You can still use this package then! I made the function
~ivy-quick-find-files-list-files~ specifically for this kind of
situation. For instance, if you are an ido user, you could write an
~ido-quick-find-files-list-files~ function like so:
#+begin_src emacs-lisp
  (defun my/ido-quick-find-files ()
    (interactive)
    (find-file (ido-completing-read "Open file: "
                                    (ivy-quick-find-files-list-files))))
#+end_src

* Upcoming changes
Plans exist to customize the maximum depth at which ~find~ and ~fd~ are to
search for files.

* License 
~ivy-quick-find-files.el~ is available under the GNU GPL-3.0
