1 From 728d397b21982af88737277fd9d6939a7b558786 Mon Sep 17 00:00:00 2001 2 From: Christian Tenllado <ctenllado@gmail.com> 3 Date: Tue, 14 Apr 2020 23:31:15 +0200 4 Subject: [PATCH] Multiple scratchpads 5 6 This patch enables multiple scratchpads, each with one asigned window. 7 This enables the same scratchpad workflow that you have in i3. 8 9 Scratchpads are implemented as special tags, whose mask does not 10 apply to new spawned windows. To assign a window to a scratchpad you 11 have to set up a rule, as you do with regular tags. 12 13 Windows tagged with scratchpad tags can be set floating or not in the 14 rules array. Most users would probably want them floating (i3 style), 15 but having them tiled does also perfectly work and might fit better the 16 DWM approach. In case they are set floating, the patch moves them to the 17 center of the screen whenever they are shown. The patch can easily be 18 modified to make this last feature configurable in the rules array (see 19 the center patch). 20 21 The togglescratch function, borrowed from the previous scratchpad patch 22 and slightly modified, can be used to spawn a registered scratchpad 23 process or toggle its view. This function looks for a window tagged with 24 the selected scratchpad tag. If it is found its view is toggled. If it is 25 not found the corresponding registered command is spawned. The 26 config.def.h shows three examples of its use to spawn a terminal in the 27 first scratchpad tag, a second terminal running ranger on the second 28 scratchpad tag and the keepassxc application to manage passwords on a 29 third scratchpad tag. 30 31 If you prefer to spawn your scratchpad applications from the startup 32 script, you might opt for binding keys to toggleview instead, as 33 scratchpads are just special tags (you may even extend the TAGKEYS macro 34 to generalize the key bindings). 35 --- 36 config.def.h | 28 ++++++++++++++++++++++++---- 37 dwm.c | 43 +++++++++++++++++++++++++++++++++++++++++-- 38 2 files changed, 65 insertions(+), 6 deletions(-) 39 40 diff --git a/config.def.h b/config.def.h 41 index 1c0b587..06265e1 100644 42 --- a/config.def.h 43 +++ b/config.def.h 44 @@ -18,17 +18,33 @@ static const char *colors[][3] = { 45 [SchemeSel] = { col_gray4, col_cyan, col_cyan }, 46 }; 47 48 +typedef struct { 49 + const char *name; 50 + const void *cmd; 51 +} Sp; 52 +const char *spcmd1[] = {"st", "-n", "spterm", "-g", "120x34", NULL }; 53 +const char *spcmd2[] = {"st", "-n", "spfm", "-g", "144x41", "-e", "ranger", NULL }; 54 +const char *spcmd3[] = {"keepassxc", NULL }; 55 +static Sp scratchpads[] = { 56 + /* name cmd */ 57 + {"spterm", spcmd1}, 58 + {"spranger", spcmd2}, 59 + {"keepassxc", spcmd3}, 60 +}; 61 + 62 /* tagging */ 63 static const char *tags[] = { "1", "2", "3", "4", "5", "6", "7", "8", "9" }; 64 - 65 static const Rule rules[] = { 66 /* xprop(1): 67 * WM_CLASS(STRING) = instance, class 68 * WM_NAME(STRING) = title 69 */ 70 /* class instance title tags mask isfloating monitor */ 71 - { "Gimp", NULL, NULL, 0, 1, -1 }, 72 - { "Firefox", NULL, NULL, 1 << 8, 0, -1 }, 73 + { "Gimp", NULL, NULL, 0, 1, -1 }, 74 + { "Firefox", NULL, NULL, 1 << 8, 0, -1 }, 75 + { NULL, "spterm", NULL, SPTAG(0), 1, -1 }, 76 + { NULL, "spfm", NULL, SPTAG(1), 1, -1 }, 77 + { NULL, "keepassxc", NULL, SPTAG(2), 0, -1 }, 78 }; 79 80 /* layout(s) */ 81 @@ -59,6 +75,7 @@ static char dmenumon[2] = "0"; /* component of dmenucmd, manipulated in spawn() 82 static const char *dmenucmd[] = { "dmenu_run", "-m", dmenumon, "-fn", dmenufont, "-nb", col_gray1, "-nf", col_gray3, "-sb", col_cyan, "-sf", col_gray4, NULL }; 83 static const char *termcmd[] = { "st", NULL }; 84 85 + 86 static Key keys[] = { 87 /* modifier key function argument */ 88 { MODKEY, XK_p, spawn, {.v = dmenucmd } }, 89 @@ -84,6 +101,9 @@ static Key keys[] = { 90 { MODKEY, XK_period, focusmon, {.i = +1 } }, 91 { MODKEY|ShiftMask, XK_comma, tagmon, {.i = -1 } }, 92 { MODKEY|ShiftMask, XK_period, tagmon, {.i = +1 } }, 93 + { MODKEY, XK_y, togglescratch, {.ui = 0 } }, 94 + { MODKEY, XK_u, togglescratch, {.ui = 1 } }, 95 + { MODKEY, XK_x, togglescratch, {.ui = 2 } }, 96 TAGKEYS( XK_1, 0) 97 TAGKEYS( XK_2, 1) 98 TAGKEYS( XK_3, 2) 99 @@ -106,7 +126,7 @@ static Button buttons[] = { 100 { ClkStatusText, 0, Button2, spawn, {.v = termcmd } }, 101 { ClkClientWin, MODKEY, Button1, movemouse, {0} }, 102 { ClkClientWin, MODKEY, Button2, togglefloating, {0} }, 103 - { ClkClientWin, MODKEY, Button3, resizemouse, {0} }, 104 + { ClkClientWin, MODKEY, Button1, resizemouse, {0} }, 105 { ClkTagBar, 0, Button1, view, {0} }, 106 { ClkTagBar, 0, Button3, toggleview, {0} }, 107 { ClkTagBar, MODKEY, Button1, tag, {0} }, 108 diff --git a/dwm.c b/dwm.c 109 index 4465af1..646aa1a 100644 110 --- a/dwm.c 111 +++ b/dwm.c 112 @@ -54,7 +54,10 @@ 113 #define MOUSEMASK (BUTTONMASK|PointerMotionMask) 114 #define WIDTH(X) ((X)->w + 2 * (X)->bw) 115 #define HEIGHT(X) ((X)->h + 2 * (X)->bw) 116 -#define TAGMASK ((1 << LENGTH(tags)) - 1) 117 +#define NUMTAGS (LENGTH(tags) + LENGTH(scratchpads)) 118 +#define TAGMASK ((1 << NUMTAGS) - 1) 119 +#define SPTAG(i) ((1 << LENGTH(tags)) << (i)) 120 +#define SPTAGMASK (((1 << LENGTH(scratchpads))-1) << LENGTH(tags)) 121 #define TEXTW(X) (drw_fontset_getwidth(drw, (X)) + lrpad) 122 123 /* enums */ 124 @@ -211,6 +214,7 @@ static void tagmon(const Arg *arg); 125 static void tile(Monitor *); 126 static void togglebar(const Arg *arg); 127 static void togglefloating(const Arg *arg); 128 +static void togglescratch(const Arg *arg); 129 static void toggletag(const Arg *arg); 130 static void toggleview(const Arg *arg); 131 static void unfocus(Client *c, int setfocus); 132 @@ -299,6 +303,11 @@ applyrules(Client *c) 133 { 134 c->isfloating = r->isfloating; 135 c->tags |= r->tags; 136 + if ((r->tags & SPTAGMASK) && r->isfloating) { 137 + c->x = c->mon->wx + (c->mon->ww / 2 - WIDTH(c) / 2); 138 + c->y = c->mon->wy + (c->mon->wh / 2 - HEIGHT(c) / 2); 139 + } 140 + 141 for (m = mons; m && m->num != r->monitor; m = m->next); 142 if (m) 143 c->mon = m; 144 @@ -308,7 +317,7 @@ applyrules(Client *c) 145 XFree(ch.res_class); 146 if (ch.res_name) 147 XFree(ch.res_name); 148 - c->tags = c->tags & TAGMASK ?
