How do I customize the underline position and width?

[UtkarshVerma]

The underline looks a bit thicker than I prefer. Here's a comparison between Alacritty and st.

Is there a way I could make the underline thinner, and maybe position it a couple of pixels below?

Hmm, changing the + 1 here to + 2 gives a 1 pixel space between the text and the underline.

st-flexipatch/x.c

Lines 2304 to 2305 in 4a156b9

	XftDrawRect(xw.draw, fg, winx, winy + dc.font.ascent + 1,
	width, 1);

If I changed that to + 3 then it disappeared as the next line (my prompt) was overwriting it. Maybe + 2 is enough here.

Weirdly, that doesn't work for me. I don't see any difference. Here are the patches I'm using: https://github.com/UtkarshVerma/st-flexipatch/blob/mine/patches.h

Right, you are using the undercurl patch which has various underline variants. Not sure how exactly to adjust that.

I decided to disable undercurl patch, and got what I wanted by modifying the source. However, I feel a variable for configuring this would be better. What are your thoughts on this?
Also, I'm using +3 offset for my underline and it looks perfect.

I did a minor change in the source to set offset for the undercurl patch in UtkarshVerma@5649ac6

It doesn't allow setting width of the underline though.
