I've tested on GNOME environment, with Enlightenment, Sawmill and traditional Twm. Jan. 23, 2000 Version 0.23, mainly for bug fix. Probably this version works correctly on Gnome/Enlightenment environment. - New features: Add '-titlemode' option to show information in window's title bar, and you can freeze this with 'f' key (thanks, Bernard). Add '-viewall' option allowing to show 'dot files' and files right under the root (thanks, Nix). - Bug fixes: Fix some lacking arguments in fprintf (thanks, Gabriel). Use X events FocusIn and FocusOut instead of EnterWindow and LeaveWindow (thanks, Roger). Use a good way for getting mouse events (thanks, Alan, David and Ryan). Dec. 2, 1999 Version 0.22 Bug fixes in draw.c (Thanks to Naoki Oshiro) and task.c. Nov. 25, 1999 Version 0.2 Put under GPL, some bugfixes, make sources a bit tidy. Unify xcrvar.c into main.c. Nov. 22, 1999 Version 0.1 Post to fj.sources. WHAT IS XCRUISE? XCruise allows you to ``cruise'' within a 3D-formed file system. It constructs the universe from a directory tree, and you can move your viewpoint with mouse. 1. Analogies Directories : Galaxies (Pale blue or white rings) Files : Planets (Solid circles with warm colors) Symbolic links : Wormholes (Green curve lines) 2. The radius of a planet is determined by its mass. (proportional to the cubic root of the file size) 3. The color, the position and the direction of a star are determined by its file name. a) Stars whose name resembles each other are placed close. b) Stars whose name is short are placed close to the center of the parent galaxy. c) Stars which don't have read permission are displayed purple. 4. When you approach a galaxy, you ``enter'' the galaxy and it is set as a ``current galaxy.'' Stars in the current galaxy appears bright. 5. The universe (root directory) appears a blue ring. Move a white cursor with mouse. The left button causes forward acceleration. The middle button causes backward. You can accelerate more quickly with the right button. When you release the buttons, your ship stops. Press Q key to quit. F key to freeze the screen. If you want to change star colors, the file XCruise.ad. Enjoy a nice cruise! Take care of motion sickness. TECHNICAL NOTE This program uses readdir and lstat to get directory information. When you come a galaxy nearer, this program ``expands'' the galaxy and scans the directory recursively. When you leave the galaxy, it is ``collapsed'' to free memory. Wormholes are drawn as cubic berier curves. HISTORY When I was a university junior, I heard that tree-like file systems are not necessarily appropriate to us since we sometime remember objects with spatial hints. And I was inspired with this idea. First I developed this program on Macintosh SE/30 and ported to UNIX with monochrome X terminals. That is why this program supports -monochrome mode (but it is too slow). I wish this program inspire anybody to develop more user-friendly interfaces. MACHINES Linux 2.2 Solaris 2.6 (use gcc) Digital UNIX 4.0 NEWS-OS 4.1 (use gcc) IRIX 6.3 FreeBSD-3.2R OpenBSD 2.6 XCruise will basically work on any machine which has X.
