DWM circulate through tags

2025-05-07

Small modifications to DWM source code so far.

This is intended for my own records, I don't use git yet, perhaps I should look into it.

I haven't added any patches to my dwm 6.5 source code, but I have modified dwm.c to enable circulating through tags, and edited config.h to play nicely with Pywal16 and my French keyboard.

Super+Shift+Left/Right keys circulate through tags
Super+left/Right keys circulate through windows in a tag.

dwm.c

I added this at line 235

static void view_adjacent(const Arg *arg);

I added this function at line 2067

void
view(const Arg *arg)
{
	if ((arg->ui & TAGMASK) == selmon->tagset[selmon->seltags])
		return;
	selmon->seltags ^= 1; /* toggle sel tagset */
	if (arg->ui & TAGMASK)
		selmon->tagset[selmon->seltags] = arg->ui & TAGMASK;
	focus(NULL);
	arrange(selmon);
}

config.h

Here is my modified config.h
