Stein c2b748e793 Remove dmenumon variable 
Reasoning: Since 2011 dmenu has been capable of working out which
monitor currently has focus in a Xinerama setup, making the use
of the -m flag more or less redundant.

This is easily demonstrated by using dmenu in any other window
manager.

There used to be a nodmenu patch that provided these changes:
https://git.suckless.org/sites/commit/ed68e3629de4ef2ca2d3f8893a79fb570b4c0cbc.html

but this was removed on the basis that it was very easy to work
out and apply manually if needed.

The proposal here is to remove this dependency from dwm. The
mechanism of the dmenumon variable could be provided via a patch
if need be.

The edge case scenario that dmenu does not handle on its own, and
the effect of removing this mechanism, is that if the user trigger
focusmon via keybindings to change focus to another monitor that
has no clients, then dmenu will open on the monitor containing the
window with input focus (or the monitor with the mouse cursor if
no windows have input focus).

If this edge case is important to cover then this can be addressed
by setting input focus to selmon->barwin in the focus function if
there is no client to give focus to (rather than giving focus back
to the root window).

NRK 84d7322113 config.def.h: make keys and buttons const 
pretty much all other variables are declared as const when they're not
modified.

Stein 5799dd1fca Remove blw variable in favour of calculating the value when needed 
The purpose and reasoning behind the bar layout width (blw) variable
in dwm the way it is today may not be immediately obvious.

The use of the variable makes more sense when looking at commit
2ce37bc from 2009 where blw was initialised in the setup function
and it represented the maximum of all available layout symbols.

	for(blw = i = 0; LENGTH(layouts) > 1 && i < LENGTH(layouts); i++) {
		w = TEXTW(layouts[i].symbol);
		blw = MAX(blw, w);
	}

As such the layout symbol back then was fixed in size and both drawbar
and buttonpress depended on this variable.

The the way the blw variable is set today in drawbar means that it
merely caches the size of the layout symbol for the last bar drawn.

While unlikely to happen in practice it is possible that the last bar
drawn is not that of the currently selected monitor, which can result
in misaligned button clicks if there is a difference in layout symbol
width between monitors.

From 9b5719969ce85c3ecc0238d49c0255c5c2cc79f0 Mon Sep 17 00:00:00 2001

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
