Cursor color when there is a warning

[Germain]

Hello all !

Sorry if this message has been ever send, I do not know if my mail
work or not ...

I recently set on the cursorline in vim. The problem is that if I do a
mistake on the line, for exemple a closing parenthse, it appears in
white foreground whith a grey95 background and it is difficult to see
it. If I do not use the cursorline that type of mistake will be with a
red background and a white foreground. How can I said to vim that the
warning background should be more important than the cursorline
background ?

This is a part of my vimrc file :

set cursorline
colorscheme default
highlight IncSearch term=underline ctermfg=NONE ctermbg=NONE
guifg=NONE guibg=NONE
highlight Search term=underline ctermbg=LightGreen ctermfg=NONE
guibg=LightGreen guifg=NONE
highlight Cursor guifg=white guibg=grey30
highlight CursorLine term=underline cterm=underline guibg=grey95
highlight CursorColumn term=NONE ctermbg=grey guibg=grey95
highlight StatusLine term=reverse,bold cterm=reverse,bold gui=italic
guibg=SteelBlue guifg=white
highlight StatusLineNC term=reverse cterm=reverse gui=italic
guibg=grey75 guifg=SteelBlue

Thanks for your help

Method I: Don't set 'cursorline'.

Method II: Set the CursorLine highlighting to something that will still
let you know what the underlying colours were, for instance

hi CursorLine term=NONE,reverse
\ cterm=NONE,reverse ctermfg=NONE ctermbg=NONE
\ gui=NONE,reverse guibg=NONE guifg=NONE

which will show in red on white what would otherwise be white on red, or

hi CursorLine term=NONE,underline
\ ctermfg=NONE ctermbg=NONE cterm=NONE,underline
\ guibg=NONE guifg=NONE gui=NONE,undercurl guisp=yellow

which, in gvim, will show the cursor line in normal colours but with a
wavy yellow underline added. (You might, however, not like this second
example if you use the Vim spell checker, which uses wavy underlines
quite a lot.)

BTW, I see you already have a number of :highlight settings. Maybe it is
time to start your own color scheme. Mine,
http://users.skynet.be/antoine.mechelynck/other/almost-default.vim ,
started that way and slowly grew over the years. This way, if I try new
highlights (set from the command-line), ":syn enable" will go back to my
colorscheme rather than to the Vim default.

Thank you. Your first solution is not very pleasant ;) ! For the two
following the cursorline become to much dark ... I do not really like
that.

Looking at your color scheme file, I took the syntax for the Error
hilight and I simply change the fg color from white to blod red ! For
the cursorline I did the same as you with a light grey bg. Thus with
error in bold red on the cursorline in lightgrey, errors are clearly
visible.

What do I win if I put all my hilight in a color scheme ? Is it just
more elegant or really important for bugs or mistakes ? Actually I do
not understand a large part of your one ... and I am a little bit
afraid to try to do one like that.

That is my current vimrc file, if you have advise for me I will be
very glad !

If you put all your highlight changes (compared to the default) in a
colorscheme with a name, then you can not only test a different
colorscheme and come back to your usual, you can also turn syntax
highlighting off and on without losing your "special" highlights, you
can change one highlight group temporarily (as I did for the CursorLine
group while writing my previous post in this thread, to check if what I
was saying made sense) then easily come back to your "normal" colours,
etc. *And* if you decide to change something in your colour scheme, you
can apply it "on the fly" without restarting Vim -- just save the
modified colorscheme and do ":syntax enable" or ":syntax on" -- I'm a
little fuzzy on the difference between the two.

In summary: I believe that it is both more elegant and easier to use
once done. Of course there is some initial investment (you must write
the colorscheme in the first place).

Maybe I'll look at that vimrc someday, but please, not today.
