Install Sigrid's Rio theming patch:
.P1
; bind -ac /dist/plan9front /
; cd /sys/src/cmd/rio
; hget https://ftrv.se/_/9/patches/rio-themes.patch | patch -p5
; mk install
.P2
Themes can be installed by writing to the /mnt/wsys/theme file while a patched rio install is running.
An example theme file:
.P1
back 1e1e2e
high f38ba8
border 313234
text cdd6f4
htext 1e1e2e
title f38ba8
ltitle 6c7086
hold ffffff
lhold 3399ff
palehold 4d9bff
paletext a5adce
size f38ba8
menubar 1e1e2e
menuback 1e1e2e
menuhigh f38ba8
menuboard f38ba8
menutext cdd6f4
menuhtext 1e1e2e
.P2
The https://git.sr.ht/~ft/picker color picker utility can be used for live editing of the Rio theme with a GUI.
.P1
picker </mnt/wsys/theme >/mnt/wsys/theme
.P2
To persist the theme, you can write it to a file and add a line like this into your bin/rc/riostart:
.P1
cat lib/theme/rio.theme >/mnt/wsys/theme
.P2
.SH
acme
.PP
Acme does not include built in theming support so you will need to edit the C source code. Don't worry as its as you will mostly just be changing the colors around.
.PP
To start, run the following commands.
.P1
bind -ac /dist/plan9front /
cd /sys/src/cmd/acme
acme acme.c
.P2
.PP
You will want to edit the iconinit function to contain different definitions for the colors. Put the following CLR macro outside of the iconinit function to simplify the code:
.P1
#define CLR(c) (allocimage(display, Rect(0,0,1,1), screen->chan, 1, (c)))
.P2
.PP
Now, edit the beginning of the iconinit function to define your own colors.
.P1
void
iconinit(void)
{
Rectangle r;
Image *tmp;
/* Blue */
tagcols[BACK] = CLR(0xYOURHEXCOLOR);
tagcols[HIGH] = CLR(0xYOURHEXCOLOR);
tagcols[BORD] = CLR(0xYOURHEXCOLOR);
tagcols[TEXT] = CLR(0xYOURHEXCOLOR);
tagcols[HTEXT] = CLR(0xYOURHEXCOLOR);
/* Yellow */
textcols[BACK] = CLR(0xYOURHEXCOLOR);
textcols[HIGH] = CLR(0xYOURHEXCOLOR);
textcols[BORD] = CLR(0xYOURHEXCOLOR);
textcols[TEXT] = CLR(0xYOURHEXCOLOR);
textcols[HTEXT] = CLR(0xYOURHEXCOLOR);
