From 67d76bdc68102df976177de351f65329d8683064 Mon Sep 17 00:00:00 2001 From: Chris Down Date: Thu, 2 Jul 2020 20:18:30 +0100 Subject: [PATCH 1/6] Do not allow focus to drift from fullscreen client via focusstack() It generally doesn't make much sense to allow focusstack() to navigate away from the selected fullscreen client, as you can't even see which client you're selecting behind it. I have had this up for a while on the wiki as a separate patch[0], but it seems reasonable to avoid this behaviour in dwm mainline, since I'm struggling to think of any reason to navigate away from a fullscreen client other than a mistake. 0: https://dwm.suckless.org/patches/alwaysfullscreen/ --- dwm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/dwm.c b/dwm.c index 664c527..b0b3466 100644 --- a/dwm.c +++ b/dwm.c @@ -835,7 +835,7 @@ focusstack(const Arg *arg) { Client *c = NULL, *i; - if (!selmon->sel) + if (!selmon->sel || selmon->sel->isfullscreen) return; if (arg->i > 0) { for (c = selmon->sel->next; c && !ISVISIBLE(c); c = c->next); From 138b405f0c8aa24d8a040cc1a1cf6e3eb5a0ebc7 Mon Sep 17 00:00:00 2001 From: Quentin Rameau Date: Mon, 12 Jul 2021 23:44:16 +0200 Subject: [PATCH 2/6] Add a configuration option for fullscreen locking Some people are annoyed to have this new behaviour forced for some application which use fake fullscreen. --- config.def.h | 1 + dwm.c | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-) diff --git a/config.def.h b/config.def.h index 1c0b587..a2ac963 100644 --- a/config.def.h +++ b/config.def.h @@ -35,6 +35,7 @@ static const Rule rules[] = { static const float mfact = 0.55; /* factor of master area size [0.05..0.95] */ static const int nmaster = 1; /* number of clients in master area */ static const int resizehints = 1; /* 1 means respect size hints in tiled resizals */ +static const int lockfullscreen = 1; /* 1 will force focus on the fullscreen window */ static const Layout layouts[] = { /* symbol arrange function */ diff --git a/dwm.c b/dwm.c index b0b3466..5e4d494 100644 --- a/dwm.c +++ b/dwm.c @@ -835,7 +835,7 @@ focusstack(const Arg *arg) { Client *c = NULL, *i; - if (!selmon->sel || selmon->sel->isfullscreen) + if (!selmon->sel || (selmon->sel->isfullscreen && lockfullscreen)) return; if (arg->i > 0) { for (c = selmon->sel->next; c && !ISVISIBLE(c); c = c->next); From 716233534b35f74dba5a46ade8f1a6f8cc72fea4 Mon Sep 17 00:00:00 2001 From: Miles Alan Date: Mon, 9 Aug 2021 18:24:14 +0200 Subject: [PATCH 3/6] Improve speed of drw_text when provided with large strings Calculates len & ew in drw_font_getexts loop by incrementing instead of decrementing; as such avoids proportional increase in time spent in loop based on provided strings size. --- drw.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/drw.c b/drw.c index 4cdbcbe..9c39086 100644 --- a/drw.c +++ b/drw.c @@ -310,8 +310,11 @@ drw_text(Drw *drw, int x, int y, unsigned int w, unsigned int h, unsigned int lp if (utf8strlen) { drw_font_getexts(usedfont, utf8str, utf8strlen, &ew, NULL); /* shorten text if necessary */ - for (len = MIN(utf8strlen, sizeof(buf) - 1); len && ew > w; len--) - drw_font_getexts(usedfont, utf8str, len, &ew, NULL); + if (ew > w) + for (ew = 0, len = 0; ew < w - lpad * 2 && len < MIN(utf8strlen, sizeof(buf) - 1); len++) + drw_font_getexts(usedfont, utf8str, len, &ew, NULL); + else + len = MIN(utf8strlen, sizeof(buf) - 1); if (len) { memcpy(buf, utf8str, len); From a786211d6cb794fba0ea406d86002c7618998afc Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma Date: Fri, 20 Aug 2021 23:09:48 +0200 Subject: [PATCH 4/6] Revert "Improve speed of drw_text when provided with large strings" This reverts commit 716233534b35f74dba5a46ade8f1a6f8cc72fea4.

Looking more closely, I realised that while we use m->showbar when updating the monitor bar margins, but don't skip actually drawing the bar if it is hidden. This patch skips drawing it entirely if that is the case. On my machine, this takes 10% of dwm's on-CPU time, primarily from restack() and focus(). When the bar is toggled on again, the X server will generate an Expose event, and we'll redraw the bar as normal as part of expose(). --- dwm.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/dwm.c b/dwm.c index 5e4d494..a96f33c 100644 --- a/dwm.c +++ b/dwm.c @@ -702,6 +702,9 @@ drawbar(Monitor *m) unsigned int i, occ = 0, urg = 0; Client *c; + if (!m->showbar) + return; + /* draw status first so it can be overdrawn by tags later */ if (m == selmon) { /* status is only drawn on selected monitor */ drw_setscheme(drw, scheme[SchemeNorm]); From d39e2f3441fe18aba8d1a62c08918a411ec6f237 Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma Date: Fri, 7 Jan 2022 12:39:18 +0100 Subject: [PATCH 6/6] bump version to 6.3 --- config.mk | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/config.mk b/config.mk index 7084c33..b6eb7e0 100644 --- a/config.mk +++ b/config.mk @@ -1,5 +1,5 @@ # dwm version -VERSION = 6.2 +VERSION = 6.3 # Customize below to fit your system
