+# [[ RYUDO ]]
+## the minimalist floatiling window manager that flows
+ -- Derek Stevens <drkste@zoho.com> 2019 --
+
+### About
+Ryudo is a fork of Russ Cox's Rio, itself a fork of David Hogan's 9wm.
+The primary additions I've made are:
+
+- URxvt is detected as a proper terminal program for sweeping out new windows
+- URxvt is the default terminal emulator (still tries 9term and then xterm if no dice)
+- Customizable colors, borders, fonts, and keybinds in config.h
+- Default keybindings:
+ + New Terminal: Super+Slash
+ + Destroy: Super+D
+ + Iconify: Super+I
+ + Maximize: Super+M
+ + moVe: Super+V
+ + Reshape: Super+R
+ + Snap Left: Super+H
+ + Snap Right: Super+L
+ + Snap Top: Super+K
+ + Snap Bottom: Super+J
+ + Snap Top-Left: Super+Q
+ + Snap Bottom-Left: Super+W
+ + Snap Bottom-Right: Super+O
+ + Snap Top-Right: Super+P
+ + Snap Floating-Center: Super+C
+ + Virtual Desk++: Super+Right
+ + Virtual Desk--: Super+Left
+
+The name "Ryudo" is a nod to "Rio" and a Japanese word for "flow."
+Using Ryudo should feel very natural -- you can do things with keyboard or
+mouse depending on the situation. Terminal launching can be done with mouse
+using the popup menu, or using the keyboar, which will spawn a terminal
+window centered taking up 9/25 of the screen (3/5 width, 3/5 height).
+
+### Dependencies, Building, Installation
+Being forked from Rio, Ryudo requires **plan9port**, **Xlib**, and **Xt**.
+Make it with **mk ryudo** and then copy the resulting executable **ryudo** to
+somewhere in your **PATH**
+
+If you try to install it with **mk install** it will probably install
+to **$PLAN9/bin/** under the name **rio**. This is less than ideal but I'm
+not a master of mk, so my protocol is to use a mk target **ryudo** which
+builds the program as **o.rio**, then calls **ryudomagic.sh** to rename
+the program.
+
+If you have trouble building, you might need to edit the **mkfile** at line 2
+to point to the proper location of your plan9port's **mkwsysrules.sh**.
+
+### Bugs and Caveats
+Of the bugs and caveats not already mentioned in Rio's readme:
+- Rendering of windows with RGBA surfaces is bound to RGB space (xshove and transset can be leveraged to get transparent terminals if you want it)
+- Since maximization doesn't use the EWM Hint for maximization, programs like Firefox will remember their window size as the maximized size and probably start offset so they aren't completely onscreen. There is probably a rule we can put in newwindow() to mitigate this, but it's not super important.
+- Probably more!
+
+### Legacy
+This is David Hogan's 9wm updated to behave more like
+Plan 9's rio.  Since I cannot get approval for the changes
+and I'd prefer not to resort to patches, I have renamed it "rio".
+
+Current incompatibilities that would be nice to fix:
+
+- The command-line options should be made more like Plan 9.
+
+- Should work out a protocol between 9term and rio so that:
+	* 9term can tell rio to blue its border during hold mode
+
+- Should change window focus on b2/b3 clicks and then
+  pass along the click event to the now-focused window.
+
+- Should change 9term to redirect b3 clicks to rio so that rio
+  can put up the usual b3 menu.
+
+Axel Belinfante contributed the code to handle border grabbing
+for resize and various other improvements.
+
+The original README is below.

+                           9wm Version 1.2
+                   Copyright 1994-1996 David Hogan.
+
+What is 9wm?
+============
+
+9wm is an X window manager which attempts to emulate the Plan 9 window
+manager 8-1/2 as far as possible within the constraints imposed by X.
+It provides a simple yet comfortable user interface, without garish
+decorations or title-bars. Or icons.  And it's click-to-type.  This
+will not appeal to everybody, but if you're not put off yet then read
+on.  (And don't knock it until you've tried it.)
+
+One major difference between 9wm and 8-1/2 is that the latter provides
+windows of text with a typescript interface, and doesn't need to run a
+separate program to emulate a terminal.  9wm, as an X window manager,
+does require a separate program.  For better 8-1/2 emulation, you should
+obtain Matthew Farrow's "9term" program (ftp://ftp.cs.su.oz.au/matty/unicode),
+version 1.6 or later (earlier versions don't cooperate with 9wm in
+implementing "hold mode").  Of course, you can run xterm under 9wm as well.
+
+What is 9wm not?
+================
+
+9wm is not a virtual window manager.  It is not customisable to any
+great extent.  It is not large and unwieldy, and doesn't use the X
+toolkit.  Requests to make it any of these things will be silently
+ignored (or flamed if I have had a bad day :-)  If you want tvtwm
+or mwm, you know where to get them...
+
+Where do I get it?
+==================
+
+The latest version of 9wm is held at ftp://ftp.cs.su.oz.au/dhog/9wm
+
+Author
+======
+
+9wm was written by David Hogan (dhog@cs.su.oz.au), a postgraduate
+student at the Basser Department of Computer Science, University
+of Sydney (http://www.cs.su.oz.au/~dhog/).

+  to make copies of it, and to distribute those copies, provided

+      (3) any unapproved changes in functionality are either
+            (i) only distributed as patches
+        or (ii) distributed as a new program which is not called 9wm
+                and whose documentation gives credit where it is due
+      (4) the author is not held responsible for any defects
+          or shortcomings in the software, or damages caused by it.
+
+  There is no warranty for this software.  Have a nice day.
+
+How do I compile/install it?
+============================
+
+Assuming your system is correctly configured, you should only need to
+run xmkmf to generate the Makefile, and then run make or make install.
+make install.man should copy the manpage (9wm.man) to the appropriate
+directory.
+
+If the make fails, complaining that the function _XShapeQueryExtension
+does not exist, try removing the "-DSHAPE" from the Imakefile, and
+run xmkmf and make again.
+
+If you don't have imake, or it is misconfigured, or you would prefer
+not to use it, try copying the file "Makefile.no-imake" to "Makefile",
+then edit the definitions in this Makefile to suit your system.  This
+may require defining suitable compilation flags for your system
+(normally imake does this for you).  For instance, on AIX you must
+include "-DBSD_INCLUDES" in CFLAGS.
+
+How do I use it?
+================
+
+See the manual page for details.  You should probably read the
+man page for 9term as well.
+
+What if I find a bug?
+=====================
+
+Please mail all bug reports to 9wm-bugs@plan9.cs.su.oz.au, so
+that I can incorporate fixes into the next release.  If you can
+tell me how to fix it, all the better.
+
+Known Problems/Bugs
+===================
+
+9wm tries hard to emulate 8-1/2, but isn't 100% compatible.  If
+you are an experienced 8-1/2 user, please be patient with it.
+
+One intentional difference between 9wm and 8-1/2 is in the behaviour
+of the menu when the last hidden item is unhidden.  Under 8-1/2, when
+the menu is next used, it pops up with "New" selected.  Under 9wm,
+the (new) last menu item will be selected.  This is a feature.  It
+may be confusing if you frequently switch between 9wm and 8-1/2.
+If you don't like this feature, email me for the one line fix.
+
+There have been some problems encountered when resizing 9term on
+some platforms.  This turns out to be a problem in 9term (actually
+in libXg, to be precise).  Newer versions of 9term should be
+immune to this, see matty@cs.su.oz.au if your 9term needs fixing.
+
+Some client programs do weird things.  One of these is Frame Maker.
+It appears that if it has a modal dialog on the screen, then if any
+of its windows are current, all keypresses are redirected to the
+modal dialog.  This is not 9wm's fault -- Frame Maker is doing this.
+
+Programs like Netscape Navigator like to put riddiculously long
+icon name properties on their windows, of the form "Netscape: blah blah".
+There is no way that I know of to stop netscape from doing this.  For this
+reason, 9wm truncates labels at the first colon it finds.  This keeps the
+button 3 menu from becoming excessively wide.  Note that with same
+applications, you can use an iconName resource to set the label; this
+works well for "xman", whose default icon name of "Manual Browser"
+is a tad too long.

+Acknowledgements
+================
+
+Thanks to Rob Pike for writing the original 8-1/2 program (and
+before that, mux) which inspired the writing of 9wm.
+
+Thanks to John Mackin, whose gwm "wool code" for emulating mux
+was also an inspiration: I used it (and hacked it) until I got
+too frustrated with gwm's large memory requirements and lack of
+speed (sorry Colas!), and decided to write a dedicated program.
+
+Thanks to Matthew Farrow for writing 9term.
+
+A big thanks to Dave Edmondson for adding support for
+multi-screen displays.

+Posting-number: Volume 2, Issue 56
+Archive-name: showevent/part01
+
+
+There are times during debugging when it would be real useful to be able to
+print the fields of an event in a human readable form.  Too many times I found 
+myself scrounging around in section 8 of the Xlib manual looking for the valid 
+fields for the events I wanted to see, then adding printf's to display the 
+numeric values of the fields, and then scanning through X.h trying to decode
+the cryptic detail and state fields.  After playing with xev, I decided to
+write a couple of standard functions that I could keep in a library and call
+on whenever I needed a little debugging verbosity.  The first function,
+GetType(), is useful for returning the string representation of the type of
+an event.  The second function, ShowEvent(), is used to display all the fields
+of an event in a readable format.  The functions are not complicated, in fact,
+they are mind-numbingly boring - but that's just the point nobody wants to
+spend the time writing functions like this, they just want to have them when
+they need them.
+
+A simple, sample program is included which does little else but to demonstrate
+the use of these two functions.  These functions have saved me many an hour 
+during debugging and I hope you find some benefit to these.  If you have any
+comments, suggestions, improvements, or if you find any blithering errors you 
+can get it touch with me at the following location:

+There are times during debugging when it would be real useful to be able to
+print the fields of an event in a human readable form.  Too many times I found 
+myself scrounging around in section 8 of the Xlib manual looking for the valid 
+fields for the events I wanted to see, then adding printf's to display the 
+numeric values of the fields, and then scanning through X.h trying to decode
+the cryptic detail and state fields.  After playing with xev, I decided to
+write a couple of standard functions that I could keep in a library and call
+on whenever I needed a little debugging verbosity.  The first function,
+GetType(), is useful for returning the string representation of the type of
+an event.  The second function, ShowEvent(), is used to display all the fields
+of an event in a readable format.  The functions are not complicated, in fact,
+they are mind-numbingly boring - but that's just the point nobody wants to
+spend the time writing functions like this, they just want to have them when
+they need them.
+
+A simple, sample program is included which does little else but to demonstrate
+the use of these two functions.  These functions have saved me many an hour 
+during debugging and I hope you find some benefit to these.  If you have any
+comments, suggestions, improvements, or if you find any blithering errors you 
+can get it touch with me at the following location:

+I have edited this code to work on modern compilers.
+
+Russ Cox
+
+---
+
+There are times during debugging when it would be real useful to be able to
+print the fields of an event in a human readable form.  Too many times I found 
+myself scrounging around in section 8 of the Xlib manual looking for the valid 
+fields for the events I wanted to see, then adding printf's to display the 
+numeric values of the fields, and then scanning through X.h trying to decode
+the cryptic detail and state fields.  After playing with xev, I decided to
+write a couple of standard functions that I could keep in a library and call
+on whenever I needed a little debugging verbosity.  The first function,
+GetType(), is useful for returning the string representation of the type of
+an event.  The second function, ShowEvent(), is used to display all the fields
+of an event in a readable format.  The functions are not complicated, in fact,
+they are mind-numbingly boring - but that's just the point nobody wants to
+spend the time writing functions like this, they just want to have them when
+they need them.
+
+A simple, sample program is included which does little else but to demonstrate
+the use of these two functions.  These functions have saved me many an hour 
+during debugging and I hope you find some benefit to these.  If you have any
+comments, suggestions, improvements, or if you find any blithering errors you 
+can get it touch with me at the following location:
