The colours 0 and 7 are distinct and can be set independently from the
foreground and background colours in most terminals. I modified defaultbg
and
defaultfg to reflect this. In retrospect, I probably should have made them >
255 to avoid conflicting with legitimate palette colours. I have done so in
the
amended patch.

Ok.

Oops. I'm not sure why my gcc didn't produce a warning.

Ok.

Ok.

Will do.

Thanks for reviewing the patch :). I have attached an amended copy below.
Let
me know if anything else requires attention.

[hackers][st][PATCH] Add support for OSC color sequences.

[Raheman Vaiya]

The attached patch adds full support for the OSC 10/11/12/4 control
sequences.
These are used by programs like vim and theme.sh to query and set terminal
colours and are supported by most major terminals (e.g alacrittty, kitty,
libvte). I submitted a patch to the wiki some time ago, but it didn't
include
support for query sequences. I am posting it here because I feel it would
be a
good candidate for inclusion into st itself.

You can test it using https://github.com/lemnos/theme.sh by running

theme.sh zenburn
theme.sh -p

Don't hesitate to let me know if I have made any grievous errors :P.

Sorry, this was an oversight. I have rectified in the attached patch. I also
used the wrong foreground escape sequence which I have adjusted.

I was not aware of this patch, but it seems to keep defaultfg and
defaultbg set to
colours 0 and 7 which is non standard behaviour. It is possible for
the background
colour to be different from colour 0/7 in most other terminals. I think this is
sufficiently standard behaviour to warrant being upstreamed rather than applied
as a separate patch.

[hackers] [st][patch] Implements OSC 11/12 for setting foreground/background colours

[Raheman Vaiya]

The attached patch adds support for the OSC 11 and OSC 12 escape
sequences. These are used by many theme scripts (e.g
https://github.com/lemnos/theme.sh) and implemented by most other
terminal emulators. This is my first patch to a suckless project. Any
feedback would be appreciated :).

Regards,
Raheman
