Subject: How to set background-color without damaging cut&paste ?
Date: Wed, 4 Sep 2024 01:28:08 +0200 [thread overview]
Message-ID: <ZtebiDWUMn0t_Y4a@disp.intra.daemon.contact> (raw)
Hi,
I'm using xterm. I want to set the background to paperwhite.
I tried this, but it makes cut&paste unuseable:
(unless (display-graphic-p)
(if (string-equal (getenv "TERM") "xterm-256color")
(add-to-list 'default-frame-alist '(background-color . "brightwhite"))
(add-to-list 'default-frame-alist '(background-color . "white")))
)
Then, given a file with this content:
First Line
Second Line
Without the color setting, I can move the mouse over the first line,
click thrice and hold to the second line; then middle-click into a
hexdumper gives this:
00000000 46 69 72 73 74 20 4c 69 6e 65 0a 53 65 63 6f 6e |First Line.Secon|
00000010 64 20 4c 69 6e 65 0a |d Line.|
However, after setting the background-color, the result is this:
00000000 46 69 72 73 74 20 4c 69 6e 65 20 20 20 20 20 20 |First Line |

00000050 0a 53 65 63 6f 6e 64 20 4c 69 6e 65 20 20 20 20 |.Second Line |
00000060 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 | |

00000090 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 | |
000000a0 20 0a | .|
It basically fills the remainder from eol to the window-border
with spaces.
Is there an other means to set the color?
I could send an ansi sequence in advance, but then how do I get the
original color back later?
