;;; Commentary:
;; Here is another two-pane mc emulation layer for emacs. It's built on top of
;; Dired and takes advantage of all its features, offering at the same time the
;; double pane interface I'd been missing so badly since I started using regu-
;; larly emacs (for everything!). I tried both Ilya Zakharevich's nc.el and
;; Kevin Burton's mc.el, but none of them was what I was looking for (though
;; mc.el was near the ideal).
;; A lot of this code was once adapted from Kevin's mc.el, but it has evolved
;; quite a bit since then. Another part (the code for file copying and renaming)
;; derives originally from the dired extensions written by Kurt Nørmark for LAML
;; (http://www.cs.aau.dk/~normark/scheme/distribution/laml/).
;; I have added to the mix several useful functions:
;; * Sunrise is implemented as a derived major mode confined inside the pane
;; buffers, so its buffers and dired ones can live together without easymenu or
;; viper to avoid key binding collisions.
;; * It automatically closes unused buffers and tries to never keep open more
;; than the one or two used to display the panes.
;; * Each pane has its own history ring: press M-y / M-u for moving backwards /
;; forwards in the history of directories.
;; * Press M-t to swap (transpose) the panes.
;; * Press C-= for "smart" file comparison using ediff. It compares together the
;; first two files marked on each pane or, if no files have been marked, it as-
;; sumes that the second pane contains a file with the same name as the selected
;; one and tries to compare these two. You can also mark whole lists of files to
;; be compared and then just press C-= for comparing the next pair.
;; * Press = for fast "smart" file comparison -- like above, but using regular
;; diff.
;; * Press C-M-= for directory comparison (by date / size / contents of files).
;; * Press C-c C-s to change the layout of the panes (horizontal/vertical/top)
;; * Press C-c / to interactively refine the contents of the current pane using
;; fuzzy (a.k.a. flex) matching, then:
;; - press Delete or Backspace to revert the buffer to its previous state
;; - press Return, C-n or C-p to exit and accept the current narrowed state
;; - press Esc or C-g to abort the operation and revert the buffer
;; - use ! to prefix characters that should NOT appear after a given position
;; Once narrowed and accepted, you can restore the original contents of the pane
;; by pressing g (revert-buffer).
;; * Press C-x C-q to put the current pane in Editable Dired mode (allows to
;; edit the pane as if it were a regular file -- press C-c C-c to commit your
;; changes to the filesystem, or C-c C-k to abort).
;; * Press y to recursively calculate the total size (in bytes) of all files and
;; directories currently selected/marked in the active pane.
;; * Sunrise VIRTUAL mode integrates dired-virtual mode to Sunrise, allowing to
;; capture find and locate results in regular files and to use them later as if
;; they were directories with all Dired and Sunrise operations at your
;; fingertips.
;; The results of the following operations are displayed in VIRTUAL mode:
;; - find-dired-name (press C-c C-n),
;; - find-grep-name (press C-c C-g),
;; - find-dired (press C-c C-f),
;; - locate (press C-c C-l),
;; - list all recently visited files (press C-c C-r -- requires recentf),
;; - list all directories in active pane's history ring (press C-c C-d).
;; * Supports AVFS (http://www.inf.bme.hu/~mszeredi/avfs/) for transparent navi-
;; gation inside compressed archives (*.zip, *.tgz, *.tar.bz2, *.deb, etc. etc.)
;; You need to have AVFS with coda or fuse installed and running on your system
;; for this to work, though.
;; * Opening terminals directly from Sunrise:
;; - Press C-c C-t to inconditionally open a new terminal into the currently
;; selected directory in the active pane.
;; - Press C-c t to switch to the last opened terminal.
;; - Press C-c T to switch to the last opened terminal and change directory
;; to the one in the current directory.
;; * Terminal integration and Command line expansion: integrates tightly with
;; eshell or term-mode to allow interaction between terminal emulators in line
;; mode (C-c C-j) and the panes: the most important navigation commands (up,
;; down, mark, unmark, go to parent dir) can be executed on the active pane
;; directly from the terminal by pressing the usual keys with Meta: <M-up>,
;; <M-down>, etc. Additionally, the following substitutions are automagically
;; performed in term-line-mode:
;; %f - expands to the currently selected file in the left pane
;; %F - expands to the currently selected file in the right pane
;; %m - expands to the list of paths of all marked files in the left pane
;; %M - expands to the list of paths of all marked files in the right pane
;; %n - expands to the list of names of all marked files in the left pane
;; %N - expands to the list of names of all marked files in the right pane
;; %d - expands to the current directory in the left pane
;; %D - expands to the current directory in the right pane
;; * Cloning of complete directory trees: press K to clone the selected files
;; and directories into the passive pane. Cloning is a more general operation
;; than copying, in which all directories are recursively created with the same
;; names and structures at the destination, while what happens to the files
;; within them depends on the option you choose:
;; - "(D)irectories only" ignores all files, copies only directories,
;; - "(C)opies" performs a regular recursive copy of all files and dirs,
;; - "(H)ardlinks" makes every new file a (hard) link to the original one
;; - "(S)ymlinks" creates absolute symbolic links for all files in the tree,
;; - "(R)elative symlinks” creates relative symbolic links.
;; * Passive navigation: the usual navigation keys (n, p, Return, U, ;) combined
;; with Meta allow to move across the passive pane without actually having to
;; switch to it.
;; * Synchronized navigation: press C-c C-z to enable / disable synchronized
;; navigation. In this mode, the passive navigation keys (M-n, M-p, M-Return,
;; etc.) operate on both panes simultaneously. I've found this quite useful for
;; comparing hierarchically small to medium-sized directory trees (for large to
;; very large directory trees one needs something on the lines of diff -r
;; though).
;; * Sticky search: press C-c s to launch an interactive search that will remain
;; active from directory to directory, until you hit a regular file or press C-g
;; to abort the operation.
;; * etc. ;-)
;; It doesn't even try to look like MC, so the help window is gone (you're in
;; emacs, so you know your bindings, right?), though if you really miss it just
;; get and install the sunrise-x-buttons extension.
;; It was written on GNU Emacs 23 on Linux, and tested on GNU Emacs 22 and 23
;; for Linux and on EmacsW32 (version 23) for Windows. I have also received
;; feedback from a user reporting it works OK on the Mac (GNU Emacs 22.2 on Mac
;; OS X Leopard). I *am* aware that there are several functions (including,
;; alas, file and directory comparison) that simply will not work on GNU Emacs
;; 21, but unfortunately I do not have the time to port them back. It doesn't
;; work either on XEmacs -- please drop me a line if you would like to help
;; porting it. All contributions and/or bug reports will be very welcome.
;; For more details on the file manager, extensions and cool tips & tricks visit
;; http://www.emacswiki.org/emacs/Sunrise_Commander
;;; Installation and Usage:
;; 1) Put this file somewhere in your emacs load-path.
;; 2) Add a (require 'sunrise-commander) to your .emacs file.
;; 3) Choose some unused extension for files to be opened in Sunrise VIRTUAL
;; mode and add it to auto-mode-alist, e.g. if you want to name your virtual
;; directories like *.svrm just add to your .emacs file a line like the
;; following:
;;
;; (add-to-list 'auto-mode-alist '("\\.srvm\\'" . sr-virtual-mode))
;; 4) Evaluate the new lines, or reload your .emacs file, or restart emacs.
;; 5) Type M-x sunrise to invoke the Sunrise Commander (or much better: bind the
;; function to your favorite key combination). The command sunrise-cd invokes
;; Sunrise and automatically selects the current file wherever it is in the
;; filesystem. Type h at any moment for information on available key bindings.
;; 6) Type M-x customize-group <RET> sunrise <RET> to customize options, fonts
;; and colors (activate AVFS support here, too).
;; 7) Enjoy :)

Additionally, the following traditional commander-style keybindings are provided
(these may be disabled by customizing the `sr-use-commander-keys' option):
F2 ............ go to directory
F3 ............ quick visit selected file
F4 ............ visit selected file
F5 ............ copy marked (or current) files and directories
F6 ............ rename marked (or current) files and directories

C-F6 .......... sort contents of current pane by size
C-F7 .......... sort contents of current pane numerically
S-F7 .......... soft-link selected file/directory to passive pane
Insert ........ mark file
C-PgUp ........ go to parent directory
Any other dired keybinding (not overridden by any of the above) can be used in
Sunrise, like G for changing group, M for changing mode and so on.
Some more bindings are provided for terminals in line mode, most useful after
opening a terminal in the viewer window (with C-c t):
(these two are only for external shells - bash, ksh, etc. not for eshell)
C-c C-j ....... put terminal in line mode
C-c C-k ....... put terminal back in char mode
M-<up>, M-P ... move cursor up in active pane
M-<down>, M-N . move cursor down in active pane
M-Return ...... visit selected file/directory in active pane
M-J ........... go to parent directory in active pane
M-M ........... mark selected file/directory in active pane
M-Backspace ... unmark previous file/directory in active pane
M-U ........... remove all marks from active pane
C-Tab ......... switch focus to active pane
In a terminal in line mode the following substitutions are also performed
automatically:
%f - expands to the currently selected file in the left pane
%F - expands to the currently selected file in the right pane
%m - expands to the list of paths of all marked files in the left pane
%M - expands to the list of paths of all marked files in the right pane
%n - expands to the list of names of all marked files in the left pane
%N - expands to the list of names of all marked files in the right pane
%d - expands to the current directory in the left pane
%D - expands to the current directory in the right pane
%% - inserts a single % sign.
