-dwm - dynamic window manager
-----------------------------
-dwm is an extremely fast, small, and dynamic X11 window manager.
-
-
-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 true
-    do
-        echo `date` `uptime | sed 's/.*://; s/,//g'`
-        sleep 1
-    done | dwm
-
-
-Configuration
--------------
-The configuration of dwm is done by creating a custom config.h
-and (re)compiling the source code.

+# dwm - dynamic window manager
+
+Sravan's custom build of dwm. Original dwm build by suckless team found here: [https://dwm.suckless.org/](https://dwm.suckless.org/)
+Choice of patches heavily inspired by [Palmdrop's custom build of dwm](https://github.com/palmdrop/dwm).
+
+## Requirements
+
+In order to build dwm you need the Xlib header files.
+
+## Installation
+
+Edit [config.mk](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.
+
+## Patches
+
+Most patches can be found on the suckless website: [https://dwm.suckless.org/patches/](https://dwm.suckless.org/patches/)
+
+* [actualfullscreen](https://dwm.suckless.org/patches/actualfullscreen/) - Actually toggle fullscreen for a window, instead of toggling the status bar and the monocle layout
+* [alwaysfullscreen](https://dwm.suckless.org/patches/alwaysfullscreen/) - Do not allow the focus to drift from the active fullscreen client when using focusstack()
+* [anybar](https://github.com/mihirlad55/dwm-anybar) (Polybar Tray Fix Version) - Enables dwm to manage external status bars such as lemonbar and polybar
+* [aspectresize](https://dwm.suckless.org/patches/aspectresize/) - Allows you to resize a window while maintaining aspect ratio
+* [attachbelow](https://dwm.suckless.org/patches/attachbelow/) (Toggleable) - Make new clients attach below the selected client, instead of always becoming the new master
+* [autoresize](https://dwm.suckless.org/patches/autoresize/) - Windows that are not visible when requesting a resize/move will get resized/moved
+* [center](https://dwm.suckless.org/patches/center/) - Add an `iscentered` rule to automatically center clients on the current monitor
+* [cfacts](https://dwm.suckless.org/patches/cfacts/) - Assign different weights to clients in their respective stack in tiled layout
+* [cfacts-vanitygaps](https://github.com/bakkeby/patches/blob/master/dwm/dwm-cfacts-vanitygaps-6.2.diff) - Vanity gaps patch compatible with cfacts patch
+* [combo](https://dwm.suckless.org/patches/combo/) - Select multiple tags for tag or view by pressing all the right keys as a combo
+* [cool autostart](https://dwm.suckless.org/patches/cool_autostart/) - Execute commands from `autostart` array in `config.h` on startup and kill processes upon dwm exit
+* [cyclelayouts](https://dwm.suckless.org/patches/cyclelayouts/) - Cycle through all available layouts
+* [dwmc](https://dwm.suckless.org/patches/dwmc/) - Simple dwmc client using a fork of [fsignal](https://dwm.suckless.org/patches/fsignal/) to communicate with dwm
+* [fixborders](https://dwm.suckless.org/patches/alpha/) - Make borders opaque
+* [ipc](https://github.com/mihirlad55/dwm-ipc) - Allows third party programs (e.g. polybar) to query window manager for information
+* [movestack](https://dwm.suckless.org/patches/movestack/) - Move clients around in the stack and swap them with the master
+* [noborder](https://dwm.suckless.org/patches/noborder/) (Floating Fix) - Remove the border when there is only one window visible
+* [swallow](https://dwm.suckless.org/patches/swallow/) - Programs opened from terminal will "swallow" the terminal
+* [unfloatvisible](https://dwm.suckless.org/patches/unfloatvisible/) - Resets `isfloating` on any visible windows that have it set
+* [xresources](https://dwm.suckless.org/patches/xresources/) - Allows dwm settings (e.g. colors) to be set in Xresources
+
+## Polybar
+
+The anybar and ipc patches above allow dwm to use an external status bar.
+I am using polybar. My config can be found [here](https://github.com/balajsra/polybar).
+
+* [Polybar DWM Module](https://github.com/mihirlad55/polybar-dwm-module)

 .SH NAME
 dwm \- dynamic window manager
 .SH SYNOPSIS
 .B dwm
 .RB [ \-v ]
 .SH DESCRIPTION
-.B dwm
-is a dynamic window manager for X11. It manages windows in tiling and floating
-modes. Either mode can be applied dynamically, optimizing the environment for
-the application in use and the task performed.
+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 tiling mode windows are managed in a master and stacking column. The master
-column contains the window which currently needs most attention, whereas the
-stacking column contains all other windows. In floating mode windows can be
-resized and moved freely. Dialog windows are always managed floating,
-regardless of the mode selected.
+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 a certain tag for viewing will display all windows with that
-tag.
+tags. Selecting certain tags displays all windows with these tags.
 .P
-.B dwm
-has a small status bar which displays the text read from standard
-input, if written. Besides that, it displays all available tags, and the title
-of the focused window. It draws a 1-pixel border around windows to
-indicate the focus state. Unfocused windows contain a small bar in front of
-them displaying their tags and title.
+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.

+.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.

-		</center>
-		<h3>Description</h3>
-		<p>
-		dwm is a dynamic window manager for X11.
-		</p>
-		<h4>Background</h4>
-		<p>
-		As founder and main developer of wmii I came to the conclusion that
-		wmii is too clunky for my needs. I don't need so many funky features
-		and all this hype about remote control through a 9P service, I only
-		want to manage my windows in a simple, but dynamic way. wmii never got
-		finished because I listened to users, who proposed arbitrary ideas I
-		considered useful. This resulted in an extreme <a
-		href="http://www.jwz.org/doc/cadt.html">CADT</a> development model,
-		which was a mistake. Thus the philosophy of dwm is simply <i>to fit my
-		needs</i> (maybe yours as well). That's it.
-		</p>
-		<h4>Differences to ion, larswm, and wmii</h4>
-		<p>
-		In contrast to ion, larswm, and wmii, dwm is much smaller, faster and simpler.
-		</p>
-		<ul>
-			<li>
-			dwm has no Lua integration, no 9P support, no editable
-			tagbars, no shell-based configuration, no remote control, and comes
-			without any additional tools like printing the selection or warping
-			the mouse.
-			</li>
-			<li>
-			dwm is only a single binary, it's source code is intended to never
-			exceed 2000 SLOC.
-			</li>
-			<li>
-			dwm is based on tagging and dynamic window management (however
-			simpler than ion, wmii or larswm). It manages windows in
-			tiling and floating modes. Either mode can be applied dynamically,
-			depending on the application in use and the task performed.
-			</li>
-			<li>
-			dwm don't distinguishes between layers, there is no floating or
-			tiled layer. Wether the clients of currently selected tag are in
-			tiled mode or not, you can re-arrange all clients on the fly.
-			Popup- and fixed-size windows are treated floating, however. 
-			</li>
-			<li>
-			dwm is customized through editing its source code, that makes it
-			extremely fast and secure - it does not process any input data
-			which hasn't been known at compile time, except window title names
-			and status text read from standard input. You don't have to learn
-			Lua/sh/ruby or some weird configuration file format (like X
-			resource files), beside C to customize it for your needs,
-			you <b>only</b> have to learn C (at least editing header files).
-			</li>
-			<li>
-			Because dwm is customized through editing its source code, it's
-			pointless to make binary packages of it. This keeps its userbase
-			small and elitist. No novices asking stupid questions.
-			</li>
-			<li>
-			dwm uses 1-pixel borders to provide the maximum of screen real
-			estate to clients. Small titlebars are only drawn in front of
-			unfocused clients.
-			</li>
-			<li>
-			dwm reads from standard input to print arbitrary status text (like
-			the date, load, battery charge). That's much simpler than
-			larsremote, wmiir and what not...
-			</li>
-			<li>
-			It can be downloaded and distributed under the conditions
-			of the <a href="http://10kloc.org/cgi-bin/hgwebdir.cgi/dwm?f=f10eb1139362;file=LICENSE;style=raw">MIT/X Consortium license</a>.
-			</li>
-			<li>
-			Optionally you can install <b>dmenu</b> to extend dwm with a wmii-alike menu.

+Subject: [PATCH] Add support for managing external status bars
+
+This patch allows dwm to manage other status bars such as
+polybar/lemonbar without them needing to set override-redirect. For
+all intents and purposes, DWM treats this bar as if it were its own
+and as a result helps the status bar and DWM live in harmony.
+
+This has a few advantages
+* The bar does not block fullscreen windows
+* DWM makes room for the status bar, so windows do not overlap the bar
+* The bar can be hidden/killed and DWM will not keep an unsightly gap
+  where the bar was
+* DWM receives EnterNotify events when your cursor enters the bar
+
+To use another status bar, set usealtbar to 1 in your config.h and set
+altbarclass to the class name (can be found using xprop) to the class
+name of your status bar. Also make sure that if your status bar will
+be displayed on top, topbar is set to 1 in your config, and if it will
+be displayed on bottom, topbar is set to 0. This patch does not
+support bars that are not docked at the top or at the bottom of your
+monitor.
+
+This verison of the patch fixes handling of polybar's tray.
+
+The patch is developed at https://github.com/mihirlad55/dwm-anybar

+Subject: [PATCH 2/2] vanitygaps - adds gaps to layouts
+
+This patch differentiates between inner and outer gaps as well as
+horizontal and vertical gaps.
+
+The logic of these layouts also aims to be pixel perfect by ensuring
+an even split of the available space and re-distributing the remainder
+among the available clients.

+MOD-CTRL-, and MOD-CTRL-.
+cycle backwards and forwards through available layouts.
+Probably only useful if you have a lot of additional layouts.
+The NULL, NULL layout should always be the last layout in your list,
+in order to guarantee consistent behavior.
