+dwm - dynamic window manager
+============================
+dwm is an extremely fast, small, and dynamic window manager for X.
+
+
+Requirements
+------------
+In order to build dwm you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (dwm is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install dwm (if
+necessary as root):
+
+ make clean install
+
+
+Running dwm
+-----------
+Add the following line to your .xinitrc to start dwm using startx:
+
+ exec dwm
+
+In order to connect dwm to a specific display, make sure that
+the DISPLAY environment variable is set correctly, e.g.:
+
+ DISPLAY=foo.bar:1 exec dwm
+
+(This will start dwm on display :1 of the host foo.bar.)
+
+In order to display status info in the bar, you can do something
+like this in your .xinitrc:
+
+ while xsetroot -name "`date` `uptime | sed 's/.*,//'`"
+ do
+ sleep 1
+ done &
+ exec dwm
+
+
+Configuration
+-------------
+The configuration of dwm is done by creating a custom config.h
+and (re)compiling the source code.

+Here are the patches and modifications applied to this dwm build
+
+* Patch Strategy
+- Review latest changes
+ Note: I'm taking all of the changes up to the latest, i.e.: 2020-07-02 19:18 Do not allow focus to drift from fullscreen client via focusstack()
+ One worry was not being able to set the selected border color properly due to a change that goes back to May 22nd 2016 (7af4d439bdb5a2e40aca69446a3367bd71431c45)
+ It appears they have just named it on this line: static const char col_cyan[] = "#005577";
+
+- Change makefile to remove config.h on 'make clean'
+ Avoid the confusion early.
+
+- Patch first, then apply customizations last
+ Customizations are easy to make, and they may trigger patch failures
+
+- When there's a choice, choose the latest diff for each patch.
+ 6.2 was on Feb 2, 2019, and there are only a handful of updates since then (see below), so this strategy should work the best.
+
+- Prioritize the largest most complex patches first.
+ The more patches are applied, the more likely a big patch will fail.
+ The bigger the patch, the more difficult it will be to do a manual merge successfully.
+
+- Prioritize the patches you want the most second.
+ More changes in the code mean the patches may fail.
+ If they all begin to fail and manual merging gets too difficult, I want the most desirable patches already applied.
+
+- Test each previous patch when applying a new patch to ensure you haven't removed previously patched-in functionality
+ Testing notes should be in
+
+- Once you have successfully applied all desired patches, create a diff and check that into github.

+* Patches Applied (in order of application)
+** DONE (01) fakefullscreen
+*** Description
+Only allow clients to "fullscreen" into space currently given to them. As an example, this will allow you to view a fullscreen video in your browser on one half of the screen, while having the other half available for other tasks.
+
+home: http://dwm.suckless.org/patches/fakefullscreen/
+direct link: http://dwm.suckless.org/patches/fakefullscreen/dwm-fakefullscreen-20170508-ceac8c9.diff
+*** Comments
+Doing this first. It's an older patch and may have immediate patch issues. It should go before ru_gaps so I can test functionality.
+*** Testing
+- Launch a browser, navigate to twitch or youtube and hit fullscreen.
+ Should maximize within old boundaries
+*** Patch Notes
+- successful on first patch
+- changed modkey to mod4map
+- changed Makefile so 'make clean' also removes config.h
+- noticed that testing the fakefullscreen, I'll sometimes have to switch client windows for the window to get the correct sizing. it seems to want to size itself as if it were going full monitor rather than the client window size.
+** DONE (02) ru_gaps (with deck and bottomstack layouts)
+CLOSED: [2021-05-08 Sat 20:13]
+- State "DONE" from "IN-PROGRESS" [2021-05-08 Sat 20:13]
+- State "IN-PROGRESS" from [2021-05-08 Sat 19:43]
+*** Description
+Runtime useless gaps
+This patch adds gaps like tilegap that are resizeable at runtime like fullgaps, but like uselessgap it removes gaps and borders when in monocle mode.
+This patch also incorporates the noborder patch, but without the check for 'is not fullscreen', to make it work properly with fakefullscreen.
+
+Notes:
+You might want to set resizehints in config.h to zero to get smooth animations when increasing or decreasing gaps.

+Additional Layouts
+Apply the following patches on top of the previous patch to add additional layouts with resizeable gap support.

+*** Comments
+I definitely want gaps for the aesthetic appeal, but I also want to be able to turn them off when I'm on a smaller laptop to save screen real estate. That rules out many of the gaps packages right there. Also, I definitely want the fakefullscreen patch, and this one plays nice with it. The fact that the other two ru_gaps patches brings in the patches for the additional layouts I want makes this an easy choice.
+*** Patch Application Notes
+- Apply the resizehints in config.def.h to zero per the description
+- Note the keyboard shortcuts to increase/decrease gaps, etc.

+The scratchpad patch allows you to spawn or restore a floating terminal window. It is usually useful to have one to do some short typing.
+A tool like detach (http://detach.sourceforge.net) turns it into a launchpad for X applications.
+By default your terminal (st) is used, and the default key binding is MODKEY+XK_grave. A config.def.h change is included in the patch.

+*** Comment
+This is my choice over the namedscratchpads patch. First, I've used this in my previous dwm build, so I know it can be applied with no issue. Second, it appears namedscratchpads works with floatrules and I can't tell any benefit from using those two patches over just this one.
+*** Patch Application Notes
+This one's a bit dangerous since it's an older patch. However, I got this to work already, so I know it can be manually merged.
+
+- We're setting up three scratchpads: (1) nmtui (2) pulsemixer (3) gnome-calculator
+- First try using terminator here ensuring that "window geometry hints" preference checked.
+- If this doesn't work, you'll have to use st (see below)
+Here's what the last patch looked like:
+/* leaving the below as documentation on how to run a specific program as a scratchpad
+const char *spcmd0[] = {"keepassxc", NULL }; */
+const char *spcmd1[] = {"st", "-n", "spnet", "-g", "65x25", "-e", "nmtui" , NULL };
+const char *spcmd2[] = {"st", "-n", "sppulse", "-g", "100x20", "-e", "pulsemixer", NULL };
+
+static Sp scratchpads[] = {
+ /* name cmd */
+ {"spnet", spcmd1},
+ {"sppulse", spcmd2},

+** DONE (04) swallow
+CLOSED: [2021-05-09 Sun 01:44]
+- State "DONE" from [2021-05-09 Sun 01:44]
+*** Description
+This patch adds "window swallowing" to dwm as known from Plan 9's windowing system rio.
+Clients marked with isterminal in config.h swallow a window opened by any child process, e.g. running xclock in a terminal. Closing the xclock window restores the terminal window in the current position.
+This patch helps users spawning a lot of graphical programs from their command line by avoiding cluttering the screen with many unusable terminals. Being deep down in a directory hierarchy just does not make the use of dmenu feasible.
+Dependencies
+- libxcb
+- Xlib-libxcb
+- xcb-res
+These dependencies are needed due to the use of the latest revision of the X Resource Extension which is unsupported in vanilla Xlib.
+
+Notes
+The window swallowing functionality requires dwm to walk the process tree, which is an inherently OS-specific task. Please contact one of the authors if you would like to help expand the list of supported operating systems.
+Only terminals created by local processes can swallow windows, and only windows created by local processes can be swallowed.

+*** Description
+This patch prevents dwm from drawing tags with no clients (i.e. vacant) on the bar.
+
+It also makes sure that pressing a tag on the bar behaves accordingly by not reserving reactive regions on the bar for vacant tags.
+
+It also stops drawing empty rectangles on the bar for non-vacant tags as there is no need anymore to distinguish vacant tags and it offers a more visible contrast than if there were filled/empty rectangles.

+This patch adds a context menu for layout switching.
+Right clicking on the layout icon brings an xmenu prompt for to pick a new layout, and switches to the selected one.
+Xmenu (https://github.com/phillbush/xmenu) needs to be installed.
+Edit layoutmenu.sh with the installed layouts and with correct indexes.
+Place layoutmenu.sh in PATH.
+The text of the menu items is for display only. Name them however you want.

+*** Description
+This patch will make dwm run "~/.dwm/autostart_blocking.sh" and "~/.dwm/autostart.sh &" before entering the handler loop. One or both of these files can be ommited.
+Be aware that dwm will not startup as long as autostart_blocking.sh is running and will stay completely unresponsive. For obvious reasons it is generally a bad idea to start X-applications here :)

+** deck
+not needed if applying ru_gaps with layouts
+*** Description
+deck is a dwm-layout which is inspired by the TTWM window manager. It applies the monocle-layout to the clients in the stack. The master-client is still visible. The stacked clients are like a deck of cards, hence the name.
+
+deck-rmaster
+The vanilla patch doesn't respect the master-area which is defined by the rmaster-patch. To make it work with the rmaster-patch apply the dwm-deck-rmaster patch on top of the dwm-deck patch.
+
+deck-tilegap
+The vanilla patch doesn't work properly with patches which add gaps. This means that when the deck-layout is activated gaps are omitted. To make it work with the tilegap-patch apply the dwm-deck-tilegap patch on top of the dwm-deck patch.
+
+deck-double
+This patch variant adds a layout function named doubledeck which is similar to the deck layout. However, rather then just creating a deck area in the stack; it also creates a deck area in the master area. This pairs nicely with the bartabgroups patch.
+
+home: http://dwm.suckless.org/patches/deck/
+
+** floatrules
+not needed as it mainly pairs with namedscratchpads
+*** Description
+This patch adds 5 extra variables to the 'rules' array in config.def.h. These are:
+
+floatx, floaty, floatw, floath (if the window has the rule isfloating, the window will spawn with the geometry specified by these vairables)
+floatborderpx (border width when window is floating)
+Setting floatborderpx to -1 (or any value less than zero) will mean that the regular border width is used.
+
+Please note that this patch needs rm config.h to be added to the Makefile.
+** focusmaster
+limited utility. only works with tiled layout
+*** Description
+Switch focus to the (tiled) master client from anywhere in the stack.

+** fullgaps
+not as full featured as ru_gaps patch
+*** Description
+This patch adds gaps between client windows. It is similar to gaps, but contains additional functionality:
+
+it also adds outer gaps (between the clients and the screen frame), as well as a gap between the master and stack area,
+it adds keybindings to change the gap size at runtime: [Alt]+[-]/[Alt]+[=] to decrease/increase the gap size and [Alt]+[Shift]+[=] to set it to zero.
+The configuration variable gappx contains the default gap size.
+home: http://dwm.suckless.org/patches/fullgaps/
+
+The following patch allows for gaps to be toggled, and also uses a Gap struct to contain the gap information, in anticipation of this being used with pertag. (To use this, apply the patch instead of the default fullgaps patch.)
+
+[Alt]+[Shift]+[=] to toggle. [Alt]+[Shift]+[-] to reset to config.h defaults.
+direct link: http://dwm.suckless.org/patches/fullgaps/dwm-fullgaps-toggle-20200830.diff
+** functionalgaps
+not as full featured as ru_gaps patch
+*** Description
+Functionalgaps combines the beautifully simplistic gaps of fullgaps with the non-gaps of singularborders and noborder. It is named functionalgaps because, since gaps are purely aesthetic, and therefore not useful whatsoever, this patch adds to their functionality by allowing them to easily be turned off.
+This patch is also unique because of its out of the box integration with pertag, allowing gaps to be enabled/disabled and sized on a per-tag basis.
+home: http://dwm.suckless.org/patches/functionalgaps/
+direct link: http://dwm.suckless.org/patches/functionalgaps/dwm-functionalgaps+pertag-6.2.diff
+(this version comes with support for pertag, + the patch itself for simplicity's sake)
+
+** movestack
+chose push up/down as it has a more recent patch
+*** Description
+This plugin allows you to move clients around in the stack and swap them with the master. It emulates the behavior off mod+shift+j and mod+shift+k in Xmonad. movestack(+1) will swap the client with the current focus with the next client. movestack(-1) will swap the client with the current focus with the previous client.
+
+Usage
+Download the patch and apply according to the general instructions.
+Include the movestack.c source file and add keys that call movestack. Example from config.default.h:
+
+ #include "movestack.c"
+ static Key keys[] = {
+ /* modifier key function argument */
+ ...
+ { MODKEY|ShiftMask, XK_j, movestack, {.i = +1 } },
+ { MODKEY|ShiftMask, XK_k, movestack, {.i = -1 } },

+** namedscratchpads
+chose scratchpads instead due to simplicity and my familiarity.
+*** Description
+Allows for the creation of multiple scratchpad windows, each assigned to different keybinds.
+On pressing the keybind the window will either:
+- Spawn based on the given command, if it's not already running
+- Toggle visibility of the window
+A new field in the rules array is added to associate the command with the corresponding rule.
+Works well with floatrules for window positioning.

+** restartsig
+Older patch. I don't see the advantage of this over .xinitrc
+*** Description
+dwm can now be restarted via MOD+CTRL+SHIFT+Q or by kill -HUP dwmpid
+In addition, a signal handler was added so that dwm cleanly quits by kill -TERM dwmpid.
+Also see selfrestart.
+
+An alternative might be to put something like this in ~/.xinitrc:
+while :; do
+ ssh-agent dwm
+done
+And then just quit/kill dwm.

+** rotatestack
+Older patch. I don't see a reason to add rotation functionality over swapping windows in the normal fashio.
+*** Description
+Stack rotation moves a client from the bottom to the top of the stack (or the other way round). This effectively rotates the clients by one position clockwise (or CCW, respectively).
+It should play well with arbitrary stack layouts and nmaster values.
+One may think of it as moving the zoom through the list of clients, very much in the same way as scrolling moves the view port around a pane.

+** selectivefakefullscreen
+I can't see a scenario where I'd prefer this behavior over simply switching layouts to monocle and then going fullscreen.
+*** Description
+Allows a specific application to fake a full screen while the rest behave as usual, it's based on Jan Hendrik Farr's patch, fakefullscreen.
+Includes a modification to config.def.h in order to add a new member to Rules struct, called "isfakefullscreen", set it to one for all the applications you want to fake a full screen.

+
+** smartborders
+not seeing the need for this patch. borders aren't disruptive as-is, so I don't feel the need to hide them.
+*** Description
+Inspired by the xmonad feature of the same name.
+Borders are only drawn when:
+- client window is floating
+- >1 tiled clients are visible
+- floating layout

+** spawnprograms
+chose to go with autostart patch instead due to not needing a recompile for startup applications
+*** Description
+This patch spawns each command in the startup_programs array on startup. It's similar to the autostart patch, however unlike autostart, it doesn't read anything from external files.
+Example usage (put this into your config.h):
+
+static const char **startup_programs[] = { termcmd, someothercmd, };

+** steam
+I'm not having any of the problems resolved by this patch. seems dangerous/hacky.
+*** Description
+The Steam client, and steam windows (games), tends to trigger a ConfigureNotify request every time the window gets focus. More so, the configure events passed along from Steam may have the wrong x and y coordinates which can make the window, if floating, jump around the screen. Another observed symptom is the steam window continuously sliding towards the bottom right corner of the screen.
+This patch works around this age-old issue by ignoring the x and y co-ordinates for ConfigureNotify requests relating to Steam windows.
+It should be noted that this is a simple and crude patch, and while it can be made more generic I have intentionally left it hardcoded against steam in particular as few other windows behaves this badly.

+** tilegap
+not as full-features as ru_gaps patch
+*** Description
+Window gaps for the tile layout done right (in my humble opinion). The same size gap between master and stack, window and window, and window and screen edge. Size configurable in config.h.

+Subject: [PATCH] Multiple scratchpads
+
+This patch enables multiple scratchpads, each with one asigned window.
+This enables the same scratchpad workflow that you have in i3.
+
+Scratchpads are implemented as special tags, whose mask does not
+apply to new spawned windows. To assign a window to a scratchpad you
+have to set up a rule, as you do with regular tags.
+
+Windows tagged with scratchpad tags can be set floating or not in the
+rules array. Most users would probably want them floating (i3 style),
+but having them tiled does also perfectly work and might fit better the
+DWM approach. In case they are set floating, the patch moves them to the
+center of the screen whenever they are shown. The patch can easily be
+modified to make this last feature configurable in the rules array (see
+the center patch).
+
+The togglescratch function, borrowed from the previous scratchpad patch
+and slightly modified, can be used to spawn a registered scratchpad
+process or toggle its view. This function looks for a window tagged with
+the selected scratchpad tag. If it is found its view is toggled. If it is
+not found the corresponding registered command is spawned. The
+config.def.h shows three examples of its use to spawn a terminal in the
+first scratchpad tag, a second terminal running ranger on the second
+scratchpad tag and the keepassxc application to manage passwords on a
+third scratchpad tag.
+
+If you prefer to spawn your scratchpad applications from the startup
+script, you might opt for binding keys to toggleview instead, as
+scratchpads are just special tags (you may even extend the TAGKEYS macro
+to generalize the key bindings).

+.SH NAME
+dwm \- dynamic window manager
+.SH SYNOPSIS
+.B dwm
+.RB [ \-v ]
+.SH DESCRIPTION
+dwm is a dynamic window manager for X. It manages windows in tiled, monocle
+and floating layouts. Either layout can be applied dynamically, optimising the
+environment for the application in use and the task performed.
+.P
+In tiled layouts windows are managed in a master and stacking area. The master
+area on the left contains one window by default, and the stacking area on the
+right contains all other windows. The number of master area windows can be
+adjusted from zero to an arbitrary number. In monocle layout all windows are
+maximised to the screen size. In floating layout windows can be resized and
+moved freely. Dialog windows are always managed floating, regardless of the
+layout applied.
+.P
+Windows are grouped by tags. Each window can be tagged with one or multiple
+tags. Selecting certain tags displays all windows with these tags.
+.P
+Each screen contains a small status bar which displays all available tags, the
+layout, the title of the focused window, and the text read from the root window
+name property, if the screen is focused. A floating window is indicated with an
+empty square and a maximised floating window is indicated with a filled square
+before the windows title. The selected tags are indicated with a different
+color. The tags of the focused window are indicated with a filled square in the
+top left corner. The tags which are applied to one or more windows are
+indicated with an empty square in the top left corner.
+.P
+dwm draws a small border around windows to indicate the focus state.
+.SH OPTIONS
+.TP
+.B \-v
+prints version information to stderr, then exits.
+.SH USAGE
+.SS Status bar
+.TP
+.B X root window name
+is read and displayed in the status text area. It can be set with the

+.TP
+.B Mod1\-Control\-[1..n]
+Add/remove all windows with nth tag to/from the view.
+.TP
+.B Mod1\-Shift\-q
+Quit dwm.
+.SS Mouse commands
+.TP
+.B Mod1\-Button1
+Move focused window while dragging. Tiled windows will be toggled to the floating state.
+.TP
+.B Mod1\-Button2
+Toggles focused window between floating and tiled state.
+.TP
+.B Mod1\-Button3
+Resize focused window while dragging. Tiled windows will be toggled to the floating state.
+.SH CUSTOMIZATION
+dwm is customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
+.SH SEE ALSO
+.BR dmenu (1),
+.BR st (1)
+.SH ISSUES
+Java applications which use the XToolkit/XAWT backend may draw grey windows
+only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
+JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
+are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
+environment variable
+.BR AWT_TOOLKIT=MToolkit
+(to use the older Motif backend instead) or running
+.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
+or
+.B wmname LG3D
+(to pretend that a non-reparenting window manager is running that the
+XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
+.BR _JAVA_AWT_WM_NONREPARENTING=1 .
+.SH BUGS
+Send all bug reports with a patch to hackers@suckless.org.

+ * dynamic window manager is designed like any other X client as well. It is
+ * driven through handling X events. In contrast to other X clients, a window
+ * manager selects for SubstructureRedirectMask on the root window, to receive
+ * events about window (dis-)appearance. Only one X connection at a time is
+ * allowed to select for this event mask.
+ *
+ * The event handlers of dwm are organized in an array which is accessed
+ * whenever a new event has been fetched. This allows event dispatching
+ * in O(1) time.
+ *
+ * Each child of the root window is called a client, except windows which have
+ * set the override_redirect flag. Clients are organized in a linked client
+ * list on each monitor, the focus history is remembered through a stack list
+ * on each monitor. Each client contains a bit array to indicate the tags of a
+ * client.
+ *
+ * Keys and tagging rules are organized as arrays and defined in config.h.
