;;; Commentary:
;;
;; BACKGROUND
;; ==========
;;
;; I needed a program to browse, organize and tag my pictures. 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 <down> 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
