Wrong mailing list?
It seems impossible to change the fore-/background color of the cursor itself.
What have you tried by yourself so far to come to this conclusion at the
end? Or is it not much more as a guess while you are waiting for a
solution from the list?
There are so many resources out there. Have you ever searched for it?
[…] the terminal is able to display 256 colors
From which terminal emulator are you talking about? And of course, are
you using ‘app-editors/vim’, ‘app-editors/vim-core’, USE=minimal or even
‘app-editors/neovim’?
Is there something special terminal-wise when setting cursor colors ?
You have to deal with terminal escape sequences which may cause
headaches. Vim usually inherits its terminal options from the terminfo
file (man 5 terminfo) specified by the ${TERM} variable or at command
line as argument for the parameter ‘-T’.
Within Vim’s command line invoke (without the quotes) ‘:set termcap’ to
see what is currently set in your Vim session. To get an idea what those
output means, read the help at ‘:help terminal-options’. But it may be
worth to check first Vim is able to set cursor shape/colour related
stuff by running:
vim --version
or within Vim any of:
:version
:echo has('cursorshape')
and look it is compiled with the '+cursorshape' feature.
When it is, you can set the related terminal options (‘t_SI’,
‘t_SR’, ‘t_EI’). Read — once more — the most obviously resource:
:help termcap-cursor-shape
:help termcap-cursor-color
for an example. As an additional hint, you can set both (shape and
colour) by concatenating terminal escape sequences. For instance:
let &t_SI = "\<Esc>]12;purple\x7\<Esc>[5 q"
sets a purple blinking IBeam cursor for insert mode (or globally, if you
are not reset the cursor style for the other modes).
Because you aren’t disclose your terminal emulator, I have to stop here.
The mentioned headaches maybe starts when:
• you are expect a ready to use solution and/or unwilling to
understand the basics of terminal escape sequences
• you only want to style the cursor in Vim (not those in the terminal)
• you are using different shapes/colours for different modes
• you are using different terminal emulators (local/remote)
• you are running terminal multiplexer > terminal emulator > Vim
• your system lacks the required terminfo file
• annoying side effects appears (e.g. with alternate screen)
• …
But there are solutions for those issues (except for point one).
Why does it fail?
Why *what* fails? How can you expect an appropriate answer with so
sparsely informations from your side?
