RYUDO(1)

NAME
ryudo - The floatiling window manager that flows

SYNOPSIS
ryudo [ -font FONTNAME ] [ -term TERMPROG ] [ -virtuals NUMVIRTS ] [ -ffm ] [ -version ] [ exit | restart ]

DESCRIPTION
Ryudo is a window manager for X which is a fork of rio from plan9port by Russ Cox, which is itself a fork of David Hogan's 9wm. Ryudo aims to be a more dynamic and configurable window manager while keeping most of the behavior of Rio.

The -font option sets the font in ryudo's menu to FONTNAME, overriding the default/fallback list in the config.h. As in rio, this is an X11 font, not a Plan 9 font.

The -term option sets the default terminal emulator, overriding the builtin defaults of urxvt, 9term, and xterm.

The -virtuals option sets the number of virtual desktops (an integer from 1 to 12). The default, and their names, is set in the config.h.

The -ffm option sets the focus model to "focus-follows-mouse", instead of "click-to-focus".

The -version option prints the current version to stderr and then exits.

If either exit or restart is given, the appropriate message is sent to an already-running ryudo instance to execute the named action.

CONFIGURATION
Many configuration options have been enabled as compile-time options configured in the config.h configuration file. The config.def.h file shipped with the source code documents all of the options and contains what I hope are sane defaults. If config.h does not exist in the source directory, it will be copied from config.def.h on build. After changing the configuration, it is necessary to run the build.sh and/or install.sh script again and restart the program.

BUILDING AND INSTALLATION
Run the provided build.sh and install.sh scripts to build and install ryudo. If run as root, they will install the program and manual pages to the PLAN9 installation path. If run as a regular user, they will install the program to ~/bin/9/ and not install the manual pages.

Building requires plan9port and the libX11 and libXT headers. Optionally, libnotify is used to show notifications when switching virtual desktops.

USAGE
Right-clicking on the desktop or an inactive window opens a menu with the following options (not all enabled by default):

•   New: Create a terminal window. Press mouse button 3 where one corner of the new window's area should start, hold it down, and drag the mouse to the opposite corner. Release the button to draw the window. The new window will be made active. The terminal program is either specified by the -term runtime option or the first of whichever of urxvt, 9term, or xterm is installed.

•   Reshape: Change the size and location of a window. Click mouse button 3 in the window to be changed, then sweep out the new window geometry as in the New operation. The changed window is made active.

•   Move: Change the location of a window. Press and hold mouse button 3 on the window to be moved, and then drag the window to its new position. The window is made active.

•   Maximize: Not enabled by default. Click mouse button 3 on the window to maximize, and it will fill the entire screen and be made active.

•   Stick: Not enabled by default. Click mouse button 3 on a window to toggle its stickiness. If sticky, it will be present on all virtual desktops. If made unsticky, the window will be restricted to the current virtual desktop.

•   Delete: Closes a window. Click the window to close with mouse button 3. SIGHUP (hangup signal) is sent to all processes in the window's process group.

•   Hide: Minimize a window. Click the window with mouse button 3. It will be hidden and its label truncated and appended to the menu. There is a compiled-in limit of 128 hidden windows.

•   LABEL: Select any label after the Hide option to restore it to the current virtual desktop.

Windows may be arranged by dragging their borders. Mouse buttons 1 or 2 can be used to drag an individual side/corner of a window around, resizing it. Mouse button 3 can be used to move the whole window.

Mouse button 2 on the desktop or an inactive window opens the virtual desktop list.

Mouse button 1 focuses a window. The click is not transferred to the window (you can only interact with it once it has been made active).

Alt-Tab cycles focus through all windows on the current desktop.

The following operations are bindable to key combinations (shown are the default bindings):

•   Launch (Super + /): Open a new terminal in the center of the screen and make it active.

•   Reshape (Super + R): Initiate a reshape operation as if the Reshape option was selected in the menu and the currently active window selected for the operation.

•   Move (Super + V): Initiate a move operation as if the Move option was selected from the menu and the currently active window selected for the operation.

•   Maximize (Super + M): Maximize the currently active window.

•   Hide (Super + I): Minimize the currently active window.

•   Unhide (Super + U): Restore the most recently minimized window.

•   Delete (Super + D): Close the currently active window.

•   Stick (Super + S): Toggle stickiness of the currently active window.

•   Zoom (Super + Z): Toggle zoom mode. In zoom mode, the currently active window is maximized, new windows are opened maximized, and using Alt-Tab to switch to another window maximizes it.

•   Tile Left (Super + H): Tile the currently active window to fill the left half of the screen.

•   Tile Right (Super + L): Tile the currently active window to fill the right half of the screen.

•   Tile Top (Super + K): Tile the currently active window to fill the top half of the screen.

•   Tile Bottom (Super + J): Tile the currently active window to fill the bottom half of the screen.

•   Tile Top-Left (Super + Q): Tile the currently active window to fill the top-left quarter of the screen.

•   Tile Bottom-Left (Super + W): Tile the currently active window to fill the bottom-left quarter of the screen.

•   Tile Bottom-Right (Super + O): Tile the currently active window to fill the bottom-right quarter of the screen.

•   Tile Top-Right (Super + P): Tile the currently active window to fill the top-right quarter of the screen.

•   Center (Super + C): Center the currently active window (primary geometry preference).

•   Center/Alternate (Super + Shift + C): Center the currently active window (alternate geometry preference).

BUGS AND CAVEATS
Multimonitor output is not currently supported -- the whole "screen" (collection of active monitors) is treated as one monitor, and keybinds and automatic window placement will not work properly.

Click events don't pass through when clicking to activate a window.

Clicking mouse button 3 on an inactive window brings up the Button 3 Menu instead of focusing the window. I personally sometimes find this behavior useful.

Programs that expect to run fullscreen will probably just open in a window the size of whatever resolution they expect to run at. Depending on the implementation, they may respond well to being maximized or you may have to change your screen resolution manually before doing so.

Fullscreen Virtualbox VM windows are a strange outlier and start with their graphics offset. Maximize the window after opening and it should be good.

There is no native support for compositing, but included is a shell script (transsetter.sh) which I use for translucent terminal and editor windows. It works well and is decently lightweight.
