I'll split this into separate patches for separate review/testing,
and we can decide how to proceed change by change. It's going to
take me a few days.

I'll post a tweaked version, keeps the bluegreen background
for the url section, and removes the lines between the menu
items.

I think you underestimate yourself. And, yes, if we have a
"dark mode", I'd want to remove '-b'.

Mm. we can probably read the 'parsed/url' before plumbing, but
I'm more interested in being able to plumb non-url text from
the page.

my plumb rules open urls in a fresh instance of mothra. my most frequent use of the plumb menu item is as a poor man's "open in new window," but i'm definiely interested in being able to plumb arbitrary text selections as well.

Default colours work for me, and I haven't checked out how libtheme
works, but it occured to me that programs often have an array of
colours, which you could prime with an rc list thus:

; colours = (ff aaaaaaff ffffffff) myprog	# -b

Sure, you need to look at the source to work out which colour is
which, but you don't have to edit it and recompile, just put your
weird preferences in a script.  If that's what you're into.
envcolours() could go in the lib... eg: (excuse my spelling)

#include <u.h>
#include <libc.h>
#include <draw.h>
enum{ONE, TWO, THREE, NCOL};
ulong rgb[NCOL] = {[ONE] 0xff0000ff, [TWO] 0x00ff00ff, [THREE] 0x0000ffff};
void envcolours(Image **a, int n){
	char *s;
	int i;
	if(s = getenv("colours"))
		for(i = 0, s = strtok(s, " "); i < n && s != nil; i++, s = strtok(nil, " "))
			rgb[i] = strtoul(s, nil, 16);
}
void main(int, char**){
	Image *col[NCOL];
	Rectangle r;
	int i;
	if(initdraw(nil, nil, "colours") < 0) sysfatal("initdraw: %r");
	r = Rect(0, 0, 1, 1);
	envcolours(col, NCOL);
	for(i = 0; i < NCOL; i++)
		if((col[i] = allocimage(display, Rect(0,0,1,1), RGBA32, 1, rgb[i])) == nil)
			sysfatal("allocimage: %r");
	r = screen->r;
	i = Dy(r) / 6;
	draw(screen, r, col[ONE], nil, ZP);
	r = insetrect(r, i);
	draw(screen, r, col[TWO], nil, ZP);
	r = insetrect(r, i);
	draw(screen, r, col[THREE], nil, ZP);
	flushimage(display, 1);
	sleep(5000);
}

thanks! i did not actually implement -b, as such. my concept was roughly: mothra.white as default, and mothra.black as -b. the only difference between my mothra.white and mothra.black is (should be) the display colors.

Finally got around to preparing patches, which should apply
cleanly on top of 9front mothra. However:

I didn't see this change in the tarballs. There just seemed to
be two different mothras, one with black and one with white
schemes.

Patches attached:

font.patch: Change font back to original.
panel.patch: Reduce drawing clutter from libpanel
monochrome.patch; Make the color scheme monochrome (all-white)
plumb.patch: add plumber

TODO:
  - Make libpanel render a bit more in the style of rio and
    everything else.
  - Merge in a version of mothra with -b, if I get it.

Subject: [PATCH] remove useless panel decoration.

stop underlining hyperlinks, and instead make them blue.

currently, lines, borders, bullet points, etc., are
defined in all sorts of different places, not even
entirely inside of libpanel.

i made no attempt to address this.  in rio, we ended
up putting all the color definitions into one file,
for easy modification.

Re: [9front] mothra: proposal

[ori]

Finally got around to preparing patches, which should apply
cleanly on top of 9front mothra. However:

> 	3.) implement -b flag for dark mode, white-on-black text.[2]
> 		a.) similar to rio -b, and vt -b.

I didn't see this change in the tarballs. There just seemed to
be two different mothras, one with black and one with white
schemes.

Patches attached:

font.patch: Change font back to original.
panel.patch: Reduce drawing clutter from libpanel
monochrome.patch; Make the color scheme monochrome (all-white)
plumb.patch: add plumber

TODO:
  - Make libpanel render a bit more in the style of rio and
    everything else.
  - Merge in a version of mothra with -b, if I get it.

i'm much more opposed to flags than theming, personally. I've set a lot of x programs to dark colors, and some of them can't be done with files or x resources. i don't like to start a whole bunch of programs and leave them running, (or rather, i didn't at the time,) so i had these wrapper scripts which started programs with the options i wanted. (not just color, other things too.) writing those scripts was irritating, especially when i had to make a new one.

it could have been worse, you could have started with sam-samterm communications. i couldn't even begin to make heads or tails of that.

it looked fine on my screen when i first made it, too; but that was in
drawterm, iirc running on windows.  if i understand correctly, the os was
making up for whatever makes it look fuzzy on native 9front.  namely,
weird interactions between how ttf2subf attempts to deal with antialiasing
and whatever is painting stuff on the screen.

the font itself was converted from ttf using a pre-cinap version of ttf2subf.

there are still a couple of lines separating those sections:

	http://plan9.stanleylieber.com/mothra/img/20200319.png

but i'm not opposed to tweaking this.  my biggest desire is to
minimize the ui's decoration, and emphasize the content.

that's fine with me, too.

i'm not capable of implementing this.  also, by this logic we'd
need to change existing behavior of rio ad vt.  would we delete
the existing flags?  i'm not married to -b, but i'm also not
advocating full-blown theming.  (fwiw, i also don't quite
understand the vehement objection to it; standardizing it
in one library seems like the right approach.)

there are extensive changes in my stuff, some not related to what
we're talking about above.  i don't think it would be especially
easier to understand my attempts to parse it all out, since you
can also just diff each one on your own machine.  it's been so
long since i wrote this stuff, and i barely understood what i
was doing anyway, that you will probably understand my code
better than i did/do, myself.

to think, many years ago i thought mothra would be a good entry
point to c.  my changes to it are still the most c i've ever
written in one place.

caveat:

mothra sometimes only knows relative urls (because some web
pages only offer relative urls as links), and relies on webfs
to figure out the correct request to match whatever it clicks
on.  this sometimes breaks plumbing, as i implemented it.

Thanks for doing the work. I'll take a look at the code soon,

I'm mostly ok with this, though I'm not a big fan of losing the
"command" vs "body" visual distinction. I also see lines drawn
between menu items. I may want to tweak it a bit more to match
the look of rio/sam windows.

I don't like theming, but I like the propagation of dark mode
flags even less. If we want this, libdraw needs to signal to
programs which colors they should use, without a '-b' flag.

I know that this way lies bikeshedding. *sigh*.

Sending this out in the form of patches would make it easier
to see what's changed.

The plumb menu is a definite yes from me.
