+**** Finding files from EMMS
+:PROPERTIES:
+:CUSTOM_ID: Packages-Configuration-Applications-EMMS-and-Media-Finding-files-from-EMMS-as6fgpv0baj0
+:header-args:emacs-lisp: :tangle no
+:END:
+EMMS has two default ways of finding files: either a built-in function
+relatively slow but portable, or with ~find~ which is arguably faster
+but less portable. Honestly, I don’t care about portability, I’ll
+always use this Emacs config on Linux, but I don’t want to use ~find~
+either since there is something even faster: ~fd~.
+
+First we’ll declare a variable that can hold the path to the ~fd~
+executable:
+#+name: emms-fd-name
+#+begin_src emacs-lisp
+(defvar emms-source-file-fd (executable-find "fd"))
+#+end_src
+
+Then, we need to declare a new function that will use ~fd~ to find
+files. The function, as specified by the documentation of
+~emms-source-file-directory-tree-function~, receives two arguments ~dir~
+and ~regex~. We can work with that!
+#+name: emms-fd-function
+#+begin_src emacs-lisp
+(defun emms-source-file-directory-tree-fd (dir regex)
+  "Return a list of all files under DIR that match REGEX.
+This function uses the external fd utility. The name for fd may
+be supplied using `emms-source-file-fd'."
+  (with-temp-buffer
+    (call-process emms-source-file-fd
+                  nil t nil
+                  "-L" ; follow symlinks
+                  regex
+                  "-t f"
+                  (expand-file-name dir))
+    (delete ""
+            (split-string (buffer-substring (point-min)
+                                          (point-max))
+                          "\n"))))
+#+end_src
+
+We can finally set this function as our search function.
+#+name: emms-search-set-variable
+#+begin_src emacs-lisp
+(setq emms-source-file-directory-tree-function #'emms-source-file-directory-tree-fd)
+#+end_src
