From c2b748e7931e5f28984efc236f9b1a212dbc65e8 Mon Sep 17 00:00:00 2001 From: Stein Date: Fri, 26 Aug 2022 14:48:46 +0200 Subject: [PATCH] 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). --- config.def.h | 3 +-- dwm.c | 2 -- 2 files changed, 1 insertion(+), 4 deletions(-) diff --git a/config.def.h b/config.def.h index 9efa774..061ad66 100644 --- a/config.def.h +++ b/config.def.h @@ -56,8 +56,7 @@ static const Layout layouts[] = { #define SHCMD(cmd) { .v = (const char*[]){ "/bin/sh", "-c", cmd, NULL } } /* commands */ -static char dmenumon[2] = "0"; /* component of dmenucmd, manipulated in spawn() */ -static const char *dmenucmd[] = { "dmenu_run", "-m", dmenumon, "-fn", dmenufont, "-nb", col_gray1, "-nf", col_gray3, "-sb", col_cyan, "-sf", col_gray4, NULL }; +static const char *dmenucmd[] = { "dmenu_run", "-fn", dmenufont, "-nb", col_gray1, "-nf", col_gray3, "-sb", col_cyan, "-sf", col_gray4, NULL }; static const char *termcmd[] = { "st", NULL }; static const Key keys[] = { diff --git a/dwm.c b/dwm.c index 253aba7..e5efb6a 100644 --- a/dwm.c +++ b/dwm.c @@ -1639,8 +1639,6 @@ sigchld(int unused) void spawn(const Arg *arg) { - if (arg->v == dmenucmd) - dmenumon[0] = '0' + selmon->num; if (fork() == 0) { if (dpy) close(ConnectionNumber(dpy));
