-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 true
-    do
-        echo `date` `uptime | sed 's/.*,//'`
-        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).

- * 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.
- *
- * Calls to fetch an X event from the event queue are blocking.  Due reading
- * status text from standard input, a select()-driven main loop has been
- * implemented which selects for reads on the X connection and STDIN_FILENO to
- * handle all data smoothly. 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 global
- * doubly-linked client list, the focus history is remembered through a global
- * stack list. Each client contains an array of Bools of the same size as the
- * global tags array to indicate the tags of a client.  For each client dwm
- * creates a small title window, which is resized whenever the (_NET_)WM_NAME
- * properties are updated or the client is moved/resized.
- *
- * Keys and tagging rules are organized as arrays and defined in the config.h
- * file. These arrays are kept static in event.o and tag.o respectively,
- * because no other part of dwm needs access to them.  The current layout is
- * represented by the lt pointer.
- *

+From a046eabd24a430ee2a7348a807057dc7c42f7cec Mon Sep 17 00:00:00 2001
+From: mihirlad55 <mihirlad55@gmail.com>
+Date: Sat, 5 Sep 2020 00:51:33 +0000
+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.

+Date: Thu, 24 May 2018 00:56:56 -0400
+Subject: [PATCH] Function to cycle through available layouts.
+
+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.
