I got +;; tired of the old gallery program I used as it did not allow +;; multi-file operations easily. Also, it put things out of my +;; control. Image viewing programs I tested did not allow multi-file +;; operations or did not do what I wanted it to. +;; +;; So, I got the idea to use the wonderful functionality of Emacs and +;; `dired' to do it. It would allow me to do almost anything I wanted, +;; which is basically just to browse all my pictures in an easy way, +;; letting me manipulate and tag them in various ways. `dired' already +;; provide all the file handling and navigation facilities; I only +;; needed to add some functions to display the images. +;; +;; I briefly tried out thumbs.el, and although it seemed more +;; powerful than this package, it did not work the way I wanted to. It +;; was too slow to created thumbnails of all files in a directory (I +;; currently keep all my 2000+ images in the same directory) and +;; browsing the thumbnail buffer was slow too. tumme.el will not +;; create thumbnails until they are needed and the browsing is done +;; quickly and easily in dired. I copied a great deal of ideas and +;; code from there though... :) +;; +;; About the name: tumme means thumb in Swedish and it is used for +;; working with thumbnails, so... :) If you want to know how to +;; pronounce it, go to the page on EmacsWiki and download the .ogg +;; file from there. +;; +;; `tumme' stores the thumbnail files in `tumme-dir' using the file +;; name format ORIGNAME.thumb.ORIGEXT. For example +;; ~/.tumme/myimage01.thumb.jpg. The "database" is for now just a +;; plain text file with the following format: +;; +;; file-name-non-directory;comment:comment-text;tag1;tag2;tag3;...;tagN +;; +;; +;; PREREQUISITES +;; ============= +;; +;; * The ImageMagick package. Currently, `convert' and `mogrify' are +;; used. Find it here: http://www.imagemagick.org. +;; +;; * For non-lossy rotation of JPEG images, the JpegTRAN program is +;; needed. +;; +;; * For `tumme-get-exif-data' and `tumme-write-exif-data' to work, +;; the command line tool `exiftool' is needed. It can be found here: +;; http://www.sno.phy.queensu.ca/~phil/exiftool/. These two functions +;; are, among other things, used for writing comments to image files +;; using `tumme-thumbnail-set-image-description' and to create +;; "unique" file names using `tumme-get-exif-file-name' (used by +;; `tumme-copy-with-exif-file-name'). +;; +;; +;; USAGE +;; ===== +;; +;; If you plan to use tumme much, setting up key bindings for it in +;; dired is a good idea: +;; +;; (tumme-setup-dired-keybindings) +;; +;; Next, do M-x tumme-dired RET. This will ask you for a directory +;; where image files are stored, setup a useful window configuration +;; and enable the two special modes that tumme provides. NOTE: If you +;; do not want tumme to split your windows, call it with a prefix +;; argument. +;; +;; Start viewing thumbnails by doing C-S-n and C-S-p to go up and down +;; in the dired buffer while at the same time displaying a thumbnail +;; image. The thumbnail images will be created on the fly, and +;; cached. This means that the first time you browse your images, it +;; will be a bit slow because the thumbnails are created. If you want +;; to avoid this, you can pre-create the thumbnail images by marking +;; all images in dired (% m \.jpg$ RET) and then do M-x +;; tumme-create-thumbs. +;; +;; Next, try `tumme-display-thumbs' (C-t d). If no file is marked, a +;; thumbnail for the file at point will show up in +;; `tumme-thumbnail-buffer'. If one or more files are marked, +;; thumbnails for those files will be displayed. +;; +;; Pressing TAB will switch to the window containing the +;; `tumme-thumbnail-buffer' buffer. In there you can move between +;; thumbnail images and display a semi-sized version in an Emacs +;; buffer (RET), or the original image in an external viewer +;; (C-RET). By pressing SPC or DEL you will navigate back and fort +;; while at the same time displaying each image in Emacs. You can also +;; navigate using arrow keys. Comment a file by pressing "c". Press +;; TAB to get back to dired. +;; +;; While in dired mode, you can tag and comment files, you can tell +;; `tumme' to mark files with a certain tag (using a regexp) etc. +;; +;; The easiest way to see the available commands is to use the Tumme +;; menus added in tumme-thumbnail-mode and dired-mode. +;; +;; +;; LIMITATIONS +;; =========== +;; +;; * In order to work well, `tumme' require that all your images have +;; unique names. The reason is the way thumbnail file names are +;; generated. I will probably not fix this problem as my images all +;; have unique names. +;; +;; * Supports all image formats that Emacs and convert supports, but +;; the thumbnails are hard-coded to JPEG format. +;; +;; * WARNING: The "database" format used might be changed so keep a +;; backup of `tumme-db-file' when testing new versions. +;; +;; +;;; History: +;; ======== +;; +;; Version 0.1, 2005-04-16 +;; +;; * First release, only browsing support for now. +;; +;; Version 0.2, 2005-04-21 +;; +;; * Changed calls to dired-filename-at-point to dired-get-filename +;; +;; Version 0.3, 2005-04-25 +;; +;; Quite a lot of changes: +;; +;; * Added basic image tagging support. No commands that make use of +;; it yet. +;; +;; * Added text properties for the thumbnail images to be able to +;; track where they came from originally. Used in `tumme-mode'. +;; +;; * Added `tumme-mode' to be used when navigating the thumbnail +;; buffer. Currently, there are commands to mark, unmark, flag and +;; jump to the original file in associated dired buffer. +;; +;; * When moving around in the thumbnail buffer (in `tumme-mode'), the +;; user can turn on tracking of the movements and let them be +;; mirrored in the associated dired buffer. +;; +;; * In this version I have been looking at some ideas in thumbs.el, +;; for example the image margin and relief and the `thumbs-mode' +;; which I copied and made the `tumme-mode' from. +;; +;; Version 0.4, 2005-05-02 +;; +;; * Renamed the functions that are to be used in `tumme-mode' in the +;; thumbnail buffer. +;; +;; * The mark, unmark and flag commands in `tumme-mode' now also moves +;; to next thumbnail, like how dired normally works. +;; +;; * Added `tumme-mode-line-up', `tumme-display-thumbs-append' and +;; `tumme-mode-delete-char'. +;; +;; * Each thumbnail's tags is now displayed when navigating among the +;; thumbnails in the thumbnail buffer. +;; +;; * Added simple slideshow functionality. +;; +;; Version 0.4.1, 2005-05-05 +;; +;; * Fixed bug in `tumme-flag-thumb-original-file' +;; +;; * Added commands to display original image in external viewer +;; (`tumme-display-external') and in a Emacs buffer +;; (`tumme-display-image'). +;; +;; * Minor code clean-up +;; +;; * Renamed some functions back again... +;; +;; * Added rotation of thumbnail images (90 degrees left and right) +;; +;; Version 0.4.2, 2005-05-06 +;; +;; * Removed need for `tumme-display-image-size' in +;; `tumme-display-image'. Now, the maximum image size that fits in +;; `tumme-display-buffer' is calculated automatically. Introduced +;; two correction variables, `tumme-display-window-width-correction' +;; and `tumme-display-window-height-correction' to be used to +;; correct width and height depending on width and height of window +;; decorations, fringes etc. This works really well! +;; +;; Version 0.4.3, 2005-05-07 +;; +;; * Added menus to `dired-mode' and `tumme-mode' +;; +;; * Added `tumme-mark-and-display-next' +;; +;; * Added `tumme-jump-thumbnail-buffer' +;; +;; * Bound TAB in `dired-mode-map' and `tumme-mode-map' to +;; `tumme-jump-thumbnail-buffer' and +;; `tumme-jump-original-dired-buffer', respectively. +;; +;; * Changed `tumme-display-image' to be more general. Now, it can be +;; used from both thumbnail buffer and dired buffer by calling +;; `tumme-display-thumbnail-original-image' and +;; `tumme-display-dired-image', respectively. +;; +;; Version 0.4.4, 2005-05-10 +;; +;; * Added `tumme-get-exif-file-name' and +;; `tumme-copy-with-exif-file-name'. These commands might not be +;; useful for all people because they are very specific. See the +;; documentation for each function for more information. +;; +;; * Added `tumme-display-next-thumbnail-original' and +;; `tumme-display-previous-thumbnail-original' to be used for easy +;; image browsing in thumbnail buffer. +;; +;; * Added support for comments. New function +;; `tumme-comment-thumbnail' added, to be used in thumbnail buffer. +;; +;; * Added `tumme-mark-tagged-files'. Use it in dired buffer to mark +;; tagged files. +;; +;; * Added `mouse-face' property `highlight' for mouse highlighting +;; and had to add a space between each thumbnail to avoid whole rows +;; to be highlighted. Doing this meant that I had to update +;; `tumme-line-up' too... +;; +;; * Added `tumme-mouse-display-image'. Use mouse-2 to display image +;; thumbnail when is highlighted. +;; +;; * As suggested by Ehud Karni on gnu.emacs.help, changed +;; `tumme-window-DIMENSION-pixels' to use `frame-char-DIMENSION' +;; instead of `frame-pixel-DIMENSION'. Feels better +;; +;; * Corrected a bug in `tumme-window-height-pixels'. I did not know +;; that the mode-line consumed one line. Also, after experimenting, it +;; seems that the only correction needed for the image display width +;; is one single pixel. I left the corection variables in there, just +;; in case someone has a system that differs. +;; +;; Version 0.4.5, 2005-05-19 +;; +;; * Added `tumme-line-up-dynamic' that calculates the number of +;; thumbnails that will fit in the thumbnail buffer's window and +;; `tumme-line-up-interactive' that asks the user. +;; +;; * Changed `tumme-display-thumbs' to call one of the `tumme-line-up' +;; functions instead of doing the line-up itself. +;; +;; * Finally! Added experimental gallery creation. See customizable +;; variables `tumme-gallery-dir', `tumme-gallery-image-root-url' and +;; `tumme-gallery-thumb-image-root-url' and new command +;; `tumme-gallery-generate'. Not beatiful, but it works quite +;; well. Probably needs some CSS-stuff in it eventually. Also, I'm not +;; sure this is the way I want to generate my image galleries in the +;; future. After all, static pages cannot do what dynamic pages using +;; PHP et al can do. Serves like a proof-of-concept of the tagging +;; though. +;; +;; * Added option to hide images with certain tags. See +;; `tumme-gallery-hidden-tags'. +;; +;; * Added `tumme-tag-thumbnail' for tagging files from thumbnail +;; buffer. +;; +;; * Added `tumme-tag-remove' and `tumme-tag-thumbnail-remove' so that +;; you can remove tags. Sorry if I have kept you waiting for +;; this... :) +;; +;; * Added option `tumme-append-when-browsing' and new command +;; `tumme-toggle-append-browsing'. +;; +;; Version 0.4.6, 2005-05-21 +;; +;; * Changed `tumme-thumb-name' to always use ".jpg" as file extension +;; for thumbnail files, instead of using the extension from the +;; original file's name. This was a very easy way to open up for +;; allowing browsing of all image file types that Emacs support, +;; assuming ImageMagick supports it too. +;; +;; * Fixed bug in `tumme-create-thumb' `tumme-rotate-thumbnail' and +;; `tumme-display-image' by adding quotes around the file names. The +;; conversion failed if the file name, or path, contained a +;; space. Also expanded the file name, as convert (or is it bash?) +;; does not work as expected for paths like "~/.tumme...". +;; +;; * Fixed another "space bug" :) in `tumme-display-external'. +;; +;; * In call to convert, added "jpeg:" in front of the output file +;; name, so that all generated files becomes JPEG files. For now, only +;; useful if `tumme-temp-image-file' does not end in .jpg. +;; +;; Version 0.4.7, 2005-05-26 +;; +;; * Change header line of tumme.el so that it does not wrap and cause +;; evaluation problems for people getting the source from Usenet. +;; +;; * Changed `tumme-write-tag' slightly to get better performance when +;; tagging many files. +;; +;; * Fixed bug in `tumme-create-gallery-lists' that made it puke if +;; there was empty lines in the database. Changed the code so that it +;; does not car about that. Also, fixed `tumme-remove-tag' so that it +;; tries not to add empty lines at the end of the database. +;; +;; * Changed all commands that execute shell commands to be +;; configurable using the `tumme-cmd-x' custom variables. This makes +;; it easier to switch among different image conversion tools which +;; might use different syntax and options. +;; +;; * Added `tumme-toggle-dired-display-properties'. +;; +;; * Added `tumme-thumb-file-name-format' and changed +;; `tumme-thumb-name' to make it possible to configure the format of +;; thumbnail files. Did not make it customizable yet though. It might +;; be a bad idea to be able to switch between formats... +;; +;; * Changed `tumme-display-window' so that it looks for tumme's +;; display window in all frames. Useful if you want to create an own +;; frame for displaying the temporary image. +;; +;; * After changing the call to `get-window-with-predicate' to scan +;; all frames for tumme's special buffers in visible windows, and also +;; changing the way tumme tracks thumbnail movement in the dired +;; buffer (now using `set-buffer' together with `set-window-point'), +;; tumme now works quite happily with all three buffers in different +;; frames. This empowers the user to setup the special buffers the way +;; that best fits his need at the time. Jumping between dired and +;; `tumme-thumbnail-buffer' work independent on in which frames they +;; are. +;; +;; * Renamed `tumme-track-movement-in-dired' to +;; `tumme-toggle-movement-tracking'. +;; +;; * Added `tumme-track-thumbnail' for movement tracking from dired +;; buffer, analoguous to the tracking done in thumbnail buffer. Both +;; uses the same custom variable `tumme-track-movement' which can be +;; toggled on and off with `tumme-toggle-movement-tracking'. This is +;; neat. :) Changed `tumme-setup-dired-keybindings' to make use of +;; this in the best way. Read more about this there. +;; +;; Version 0.4.8, 2005-06-05 +;; +;; * Changed `tumme-display-dired-image' and +;; `tumme-display-thumbnail-original-image' so that when called with a +;; prefix argument, the image is not resized in the display +;; buffer. This will be useful for later additions of image +;; manipulation commands. +;; +;; * Added `tumme-kill-buffer-and-window' to make it easy to kill the +;; tumme buffers. +;; +;; * Renamed `tumme-mode' to `tumme-thumbnail-mode'. +;; +;; * `tumme-tag-thumbnail' and `tumme-tag-thumbnail-remove' now +;; updates the tags property for the thumbnail. +;; +;; * Added `tumme-dired-display-external' to display images in +;; external viewer from dired buffer. +;; +;; * Added support for multiple files in `tumme-remove-tag' to +;; increase performance. +;; +;; * Added `tumme-display-image-mode' so that we can add image +;; manipulation commands there. +;; +;; * Added call to `tumme-display-thumb-properties' in +;; `tumme-track-thumbnail'. +;; +;; * Added command `tumme-display-current-image-in-full-size' to be +;; used in `tumme-display-image-mode'. +;; +;; * Changed `tumme-display-image' to call +;; `tumme-create-display-image-buffer' so that we are sure that +;; `tumme-display-image-buffer' is always available. +;; +;; * Added optional prefix argument to `tumme-dired-folder' that tells +;; it to skip the window splitting and just creates the needed +;; buffers. +;; +;; * Fixed bug somewhere that relied on `tumme-dired-folder' having +;; created the `tumme-display-image-buffer'. Now `tumme-dired-folder' +;; *should* not be necessary to call at all, just convenient. +;; +;; * Added tracking to `tumme-mouse-display-image'. +;; +;; * Added `tumme-mouse-select-thumbnail' and bound mouse-1 to it, so +;; that selecting a thumbnail will track the original file. +;; +;; * Added three new custom variables, `tumme-cmd-ACTION-program' to +;; make the command options cleaner and easier to read. +;; +;; * Added `tumme-display-properties-format' and +;; `tumme-format-properties-string' to make it possible to configure +;; the display format of the image file's properties. +;; +;; * Added missing (require 'format-spec) +;; +;; Version 0.4.9, 2005-09-25 +;; +;; * Fixed bug in `tumme-display-thumbs'. If a thumbnail file could +;; not be created for some reason (bad file for example), even if +;; several other thumbnails was created sucessfully, the code +;; generated an error and never continued doing the line-up. +;; +;; * Made tumme.el pass the M-x checkdoc test, phew! +;; +;; * Added `tumme-rotate-original', `tumme-rotate-original-left' and +;; `tumme-rotate-original-right' to rotate the original image from +;; thumbnail view. By default it uses JpegTRAN to rotate the images +;; non-lossy. Only works on JPEG images. The two new commands were +;; added to thumbnail mode. Thanks to Colin Marquardt who told me +;; about the "-copy all" option to jpegtran. +;; +;; * Added the functions `tumme-get-exif-data' and +;; `tumme-set-exif-data' for reading and writing EXIF data to image files. +;; +;; * Rewrote `tumme-get-exif-file-name': now uses +;; `tumme-get-exif-data'. Slight change to replace spaces with +;; underscores (tt seems not all cameras use the exact same format for +;; DateTimeOriginal). Added code for handling files that has no +;; EXIF-data (use file's timestamp instead). +;; +;; * Changed from using the exif program to exiftool because exiftool +;; also handles writing of EXIF data, which is very useful. +;; +;; * Added the command `tumme-thumbnail-set-image-description' that +;; can be used to set the EXIF tag ImageDescription. Thanks to Colin +;; Marquardt for the suggestion. +;; +;; * Added `tumme-toggle-mark-thumb-original-file' and +;; `tumme-mouse-toggle-mark' and changed +;; `tumme-modify-mark-on-thumb-original-file' to support toggling of +;; mark of original image file in dired, from +;; `tumme-thumbnail-mode'. Bound C-down-mouse-1 +;; `tumme-mouse-toggle-mark' to in `tumme-thumbnail-mode'. +;; +;; * Changed `tumme-mouse-select-thumbnail' to also display properties +;; after the file is selected. +;; +;; Version 0.4.10, 2005-11-07 +;; +;; * Renamed `tumme-dired-folder' to `tumme-dired'. +;; +;; * Changed format of the database file slightly, now the full path +;; and file name is used. Had to change most of the tag functions +;; (writing, reading, searching) slightly to cope with the change. If +;; you are an old tumme user, you have to update your database +;; manually, probably you only need to prefix all rows with a +;; directory name to get the full path and file name. +;; +;; * Removed `tumme-thumb-file-name-format'. Added +;; `tumme-thumbnail-storage' and changed `tumme-thumb-name' to provide +;; two different thumbnail storage schemes. It is no longer necessary +;; to have unique image file names to use tumme fully. +;; +;; * As a consequence of the above, gallery generation is currently +;; not supported if per-directory thumbnail file storage is used. +;; +;; * Changed parameters to `tumme-create-thumb'. +;; +;; * To be included in Emacs 22. +;; +;; +;; +;; TODO +;; ==== +;; +;; * Support gallery creation when using per-directory thumbnail +;; storage. +;; +;; * Some sort of auto-rotate function based on rotate info in the +;; EXIF data. +;; +;; * Check if exiftool exist before trying to call it to give a better +;; error message. +;; +;; * Investigate if it is possible to also write the tags to the image +;; files. +;; +;; * From thumbs.el: Add an option for clean-up/max-size functionality +;; for thumbnail directory. +;; +;; * From thumbs.el: Add setroot function. +;; +;; * Asynchronous creation of thumbnails. +;; +;; * Add `tumme-display-thumbs-ring' and functions to cycle that. Find +;; out which is best, saving old batch just before inserting new, or +;; saving the current batch in the ring when inserting it. Adding it +;; probably needs rewriting `tumme-display-thumbs' to be more general. +;; +;; * Find some way of toggling on and off really nice keybindings in +;; dired (for example, using C-n or instead of C-S-n). Richard +;; suggested that we could keep C-t as prefix for tumme commands as it +;; is currently not used in dired. He also suggested that +;; `dired-next-line' and `dired-previous-line' figure out if tumme is +;; enabled in the current buffer and, if it is, call +;; `tumme-dired-next-line' and `tumme-dired-previous-line', +;; respectively. +;; +;; * Enhanced gallery creation with basic CSS-support and pagination +;; of tag pages with many pictures. +;; +;; * Rewrite `tumme-modify-mark-on-thumb-original-file' to be less +;; ugly. +;; +;; * In some way keep track of buffers and windows and stuff so that +;; it works as the user expects. +;; +;; * More/better documentation +;; +;; +;;; Code: + +(require 'dired) +(require 'format-spec) + +(defgroup tumme nil + "Use dired to browse your images as thumbnails, and more." + :prefix "tumme-" + :group 'files) + +(defcustom tumme-dir "~/.tumme/" + "*Directory where thumbnail images for are stored." + :type 'string + :group 'tumme) + +(defcustom tumme-thumbnail-storage 'use-tumme-dir + "*How to store tumme's thumbnail files. +Tumme can store thumbnail files in one of two ways and this is +controlled by this variable. \"Use tumme dir\" means that the +thumbnails are stored in a central directory. \"Per directory\" +means that each thumbnail is stored in a subdirectory called +\".tumme\" in the same directory where the image file is." + :type '(choice :tag "How to store thumbnail files" + (const :tag "Use tumme-dir" use-tumme-dir) + (const :tag "Per-directory" per-directory)) + :group 'tumme) + +(defcustom tumme-db-file "~/.tumme/.tumme_db" + "*Database file where file names and their associated tags are stored." + :type 'string + :group 'tumme) + +(defcustom tumme-temp-image-file "~/.tumme/.tumme_temp" + "*Name of temporary image file used by various commands." + :type 'string + :group 'tumme) + +(defcustom tumme-gallery-dir "~/.tumme/.tumme_gallery" + "*Directory to store generated gallery html pages. +This path needs to be \"shared\" to the public so that it can access +the index.html page that tumme creates." + :type 'string + :group 'tumme) + +(defcustom tumme-gallery-image-root-url +"http://your.own.server/tummepics" + "*URL where the full size images are to be found. +Note that this path has to be configured in your web server.
