By default it looks for images cover_small.jpg, -;; cover_med.jpg, etc. Customize emms-browser-covers to use your own -;; covers. Note that you'll probably want to resize your existing -;; covers to particular sizes. Suggested sizes are 100x100 for small, -;; and 200x200 for medium. - -;; Also emacs by default will jump around a lot when scrolling a -;; buffer with images. Set the following variables to prevent that: - -;; scroll-up-aggressively 0.0 -;; scroll-down-aggressively 0.0 - -;; To show a 'no cover' image for albums which don't have a cover, add -;; the following code to your .emacs: - -;; (setq emms-browser-default-covers -;; (list "/path/to/cover_small.jpg" nil nil) - -;; (the medium and large images can be set too, if you want) - -;; You can download an example 'no cover' image from: -;; http://repose.cx/cover_small.jpg - -;; Filtering tracks -;; ------------------------------------------------------------------- - -;; If you want to display a subset of your collection (such as a -;; directory of 80s music, only avi files, etc), then you can make -;; some filters using code like this: - -;; ;; show everything -;; (emms-browser-make-filter "all" 'ignore) - -;; ;; Set "all" as the default filter -;; (emms-browser-set-filter (assoc "all" emms-browser-filters)) - -;; ;; show all files (no streamlists, etc) -;; (emms-browser-make-filter -;; "all-files" (emms-browser-filter-only-type 'file)) - -;; ;; show only tracks in one folder -;; (emms-browser-make-filter -;; "80s" (emms-browser-filter-only-dir "~/Mp3s/80s")) - -;; ;; show all tracks played in the last month -;; (emms-browser-make-filter -;; "last-month" (emms-browser-filter-only-recent 30)) - -;; After executing the above commands, you can use M-x -;; emms-browser-show-all, emms-browser-show-80s, etc to toggle -;; between different collections. Alternatively you can use '<' and -;; '>' to cycle through the available filters. - -;; The second argument to make-filter is a function which returns t if -;; a single track should be filtered. You can write your own filter -;; functions to check the type of a file, etc. - -;; Some more examples: - -;; ;; show only tracks not played in the last year -;; (emms-browser-make-filter "not-played" -;; (lambda (track) -;; (not (funcall (emms-browser-filter-only-recent 365) track)))) - -;; ;; show all files that are not in the pending directory -;; (emms-browser-make-filter -;; "all" -;; (lambda (track) -;; (or -;; (funcall (emms-browser-filter-only-type 'file) track) -;; (not (funcall -;; (emms-browser-filter-only-dir "~/Media/pending") track))))) - -;; Changing tree structure -;; ------------------------------------------------------------------- - -;; You can change the way the tree is displayed by modifying -;; `emms-browser-next-mapping-type'. The following code displays -;; artist->track instead of artist->album->track when you switch to -;; the 'singles' filter. - -;; (defadvice emms-browser-next-mapping-type -;; (after no-album (current-mapping)) -;; (when (eq ad-return-value 'info-album) -;; (setq ad-return-value 'info-title))) - -;; (defun toggle-album-display () -;; (if (string= emms-browser-current-filter-name "singles") -;; (ad-activate 'emms-browser-next-mapping-type) -;; (ad-deactivate 'emms-browser-next-mapping-type))) - -;; (add-hook 'emms-browser-filter-changed-hook 'toggle-album-display) - -;; Changing display format -;; ------------------------------------------------------------------- - -;; Format strings govern the way items are displayed in the browser -;; and playlist. You can customize these if you wish. - -;; `emms-browser-default-format' controls the format to use when no -;; other format has been explicitly defined. By default, only track and -;; albums deviate from the default. - -;; To customise the format of a particular type, find the name of the -;; field you want to use (eg `info-artist', `info-title', etc), and -;; insert that into emms-browser--format or -;; emms-browser-playlist--format. For example, if you wanted to -;; remove track numbers from tracks in both the browser and playlist, -;; you could do: - -;; (defvar emms-browser-info-title-format "%i%n") -;; (defvar emms-browser-playlist-info-title-format -;; emms-browser-info-title-format) - -;; The format specifiers available include: - -;; %i indent relative to the current level -;; %n the value of the item - eg -info-artist might be "pink floyd" -;; %y the album year -;; %A the album name -;; %a the artist name of the track -;; %C the composer name of the track -;; %p the performer name of the track -;; %t the title of the track -;; %T the track number -;; %cS a small album cover -;; %cM a medium album cover -;; %cL a big album cover - -;; Note that if you use track-related items like %t, it will take the -;; data from the first track. - -;; Changing display faces -;; ------------------------------------------------------------------- - -;; The faces used to display the various fields are also customizable. -;; They are in the format emms-browser--face, where type is one -;; of "year/genre", "artist", "composer", "performer", "album" or -;; "track". Note that faces lack the initial "info-" part. For example, -;; to change the artist face, type -;; M-x customize-face emms-browser-artist-face. - -;; Deleting files -;; ------------------------------------------------------------------- - -;; You can use the browser to delete tracks from your hard disk. -;; Because this is dangerous, it is disabled by default. - -;; The following code will delete covers at the same time, and remove -;; parent directories if they're now empty. - -;; (defun de-kill-covers-and-parents (dir tracks) -;; (when (> (length tracks) 1) -;; ;; if we're not deleting an individual file, delete covers too -;; (dolist (cover '("cover.jpg" -;; "cover_med.jpg" -;; "cover_small.jpg" -;; "folder.jpg")) -;; (condition-case nil -;; (delete-file (concat dir cover)) -;; (error nil))) -;; ;; try and delete empty parents - we actually do the work of the -;; ;; calling function here, too -;; (let (failed) -;; (while (and (not (string= dir "/")) -;; (not failed)) -;; (condition-case nil -;; (delete-directory dir) -;; (error (setq failed t))) -;; (setq dir (file-name-directory (directory-file-name dir))))))) -;; (add-hook 'emms-browser-delete-files-hook 'de-kill-covers-and-parents) - -;;; Code: - -(require 'cl-lib) -(require 'emms) -(require 'emms-cache) -(require 'emms-source-file) -(require 'emms-playlist-sort) -(require 'sort) -(require 'seq) - - -;; -------------------------------------------------- -;; Variables and configuration -;; -------------------------------------------------- - -(defvar emms-browser-mode-hook nil - "Emms browser mode hook.") - -(defgroup emms-browser nil - "*The Emacs Multimedia System browser" - :prefix "emms-browser-" - :group 'multimedia - :group 'applications) - -(defcustom emms-browser-default-browse-type - 'info-artist - "*The default browsing mode." - :group 'emms-browser - :type 'function) - -(defcustom emms-browser-make-name-function - 'emms-browser-make-name-standard - "*A function to make names for entries and subentries. -Overriding this function allows you to customise how various elements -are displayed.

Its clients can run in -;; their own processes (ie. as normal applications), or they can run -;; within the JACK server (ie. as a "plugin"). -;; -;; JACK was designed from the ground up for professional audio work, and -;; its design focuses on two key areas: synchronous execution of all -;; clients, and low latency operation. -;; -;; jack.el provides a fascility for starting jackd from within Emacs. -;; It also povides convenience functions for prompting the user for -;; jack client and port names in the minibuffer, as well as the -;; functions `jack-connect' and `jack-disconnect' which can be used to -;; rearrange jack port wiring with a minimum of keystrokes. - -;;; Code: - -(require 'emms-compat) - -(defgroup jack () - "Jack Audio Connection Kit" - :group 'processes) - -(defcustom jack-rc '("~/.jackdrc" "/etc/jackd.conf") - "*JACK run control paths." - :group 'jack - :type 'repeat) - -(defcustom jack-use-jack-rc t - "*If non-nil, try to retrieve jack startup arguments from run control files -listed in `jack-rc'.
