problems with vimdiff, syntax highlighting and colorscheme's

[Caleb Cushing]

attached is a screenshot demonstrating the issue, next to Funtoo and
Regen2 there is text, however it can't be seen because of the colors,
I can't even highlight it to see what's underneath, I've tried a few
different colorschemes (all distributed with vim) and all I've seen
have this problem.

Any help getting this fixed would be appreciated. I don't mind if it
wants to highlight them a bit different so I can see what's the same..
I just want to be able to read the hidden text.

I've been using these settings:

highlight DiffAdd cterm=NONE ctermfg=bg ctermbg=Green gui=NONE guifg=bg guibg=Green
highlight DiffDelete cterm=NONE ctermfg=bg ctermbg=Red gui=NONE guifg=bg guibg=Red
highlight DiffChange cterm=NONE ctermfg=bg ctermbg=Yellow gui=NONE guifg=bg guibg=Yellow
highlight DiffText cterm=NONE ctermfg=bg ctermbg=Magenta gui=NONE guifg=bg guibg=Magenta

I should just add these to my vimrc and see if it helps?

Generally, Bram (the maintainer of vim) will not include new
colorschemes in vim, I had made a request several years ago and he
refused. IMO most colorschemes in the standard vim distribution are
buggy (to some extent).

But you're strongly recommended to try the colorscheme on vim.sf.net,
most top-rated colorschemes has good support of diff mode.

See this:

bugs should be fixed. I do infact see this as a bug. I don't care that
bram won't include new colorschemes but if the existing ones are
broken then should be fixed.

I hate going through colorschemes though, does anyone have a good one
for konsole w/ dark/black background use? I realize it's a bit of a
preference but I can still ask for suggestions.

Here is my definition of "good one". I call it ~/.vim/colors/dtw.vim and
it is mostly the default colors except bugs fixed. It uses similar
colors with GUI too.

set background=dark
highlight clear

syntax reset
endif

Here is a good method to investigate color schemes:
http://vim.wikia.com/wiki/Switch_color_schemes

It's a little lengthy but it works well (I rewrote it a couple of months
ago and merged several ideas to a new script). I put my choice (elflord)
as the example at the top!

Well, you can (see after the horizontal dividing line below though), but
it might perhaps be better to start a custom colorscheme with them (so
you don't lose your "special highlights" if you try another colorscheme
then want to come back). You don't have to define every single default
highlight group in your colorscheme, you can build upon the default
colors, changing only the nondefault ones.

I'm attaching the colorscheme I use (mostly, but not only, in the GUI):
it isn't for general use, but you might view it as an example of a
colorscheme setting most colors to the default (hence its name). You can
compare it with the "default" colorscheme,
$VIMRUNTIME/colors/default.vim, which resets _all_ colors to the
defaults but defines none of them.

In any case, if the colors set for the Diff<something> highlight groups
by the commands at top aren't to your liking, then (for Console mode)
tweak the cterm= ctermfg= ctermbg= arguments (or, for GUI mode, the
correspoding gui= guifg= guibg= ones).

-----------------------------------------------------------------------

Another possibility would be, rather than adding the 4 ":highlight"
commands at top, to search the existing colorschemes for one with
support of diff highlights in Console mode, maybe as follows:

:0verbose vimgrep /\<hi\%[ghlight]\s\+Diff/ $VIMRUNTIME/colors/*.vim

which will select ":highlight" commands for those diff-something groups.
Then find a colorscheme in the lot which changes the cterm= ctermfg=
ctermbg= settings (or at least one of them) for those groups. You may
have to try several such schemes before you find one which you like.
After running the vimgrep command, ":cnext" finds the next hit,
":cnfile" goes to the next file; similarly ":cprev" ":cpfile" ":cfirst"
":clast" etc.

Note: At least one of them has distinct ":hi" lines for cterm and GUI,
which sometimes means two different ones for the same grooup.

Best regards,
Tony.

It depends on how you define "good". Everyone had their own taste.

For me this one is the best, which contains both dark and light
background schemes and I use it only in Konsole.

http://vim.sourceforge.net/scripts/script.php?script_id=760

You may or may not like it, that's up to you for choice.

+1 for peaksea

(Though I use it only with light background, I think it is worst to
check how good it's "dark side" is - in the hope that it is equally
well balanced as a light one.)

The fact that it says it supports 256 colors in konsole has me sold
(without looking) most console colorschemes are set for 16 colors, you
know... because that's all anything supports right? I mean I've seen
mplayer play full color movies without X but hey...

CSApprox.vim ( http://www.vim.org/scripts/script.php?script_id=2390 )
is a script that tries to make colorschemes look as close as possible
in 88- or 256-color terminal vim to how they look in gvim, and it
usually does a very good job. Plus, I'm the author, so if you need
support you know who to ask. I wrote it with the aim of getting
around that nasty little problem that terminals support many more
colors than colorscheme authors tend to use.

I'll check it out. peaksea's pretty cool my 1 complaint thus far is
its 'dark grey' background. is it possible to override this in 1 or 2
lines to tell it to be black? every time I see the grey my eyes want
to think there's something wrong... it just seems weird to me.. like
my eyes are only partially open..

That was in the FAQ list, but now removed. simply open the script and
search the text 'Normal' and see some line with guibg=#202020, you can
change it into guibg=#000000 which is pure black.

btw: I'm the author and you'll know who you can ask when you've got any
problems.

I changed line 258 to read as follows (I'm using background="dark" and console)

hi Normal guifg=#d0d0d0 guibg=#000000 gui=NONE

closed and reopened vim just to be sure... I still seem to be getting
a greyish background (also :source peaksea.vim :set background=dark)

[pansz]

Caleb Cushing 写道:

That's for gui, for console you could find the following line:

hi Normal ctermfg=252 ctermbg=234 cterm=NONE

and change the ctermbg=234 into ctermbg=232, (232 is black and 255 is
white, 234 is somewhere between black and white)

Xterm is not "without X", it just adds a buffer layer between the X
server and your text-based application. I have yet to see a "true" non-X
console, such as the ones you can access in runlevel 3 (multiuser with
network but no X) and into which you drop from X by hitting Alt-Ctrl-F2
to Alt-Ctrl-F6 (and out of by Alt-Ctrl-F7), which could display more
than 8 background and 16 foreground colors with blink, or 16*16 without
blink.

Tony.

I've tried fbcon (a console under framebuffer), of course you have to
boot into framebuffer to use it.

I've used framebuffer before (under RedHat) and I don't like it, it sets
too much constraints on what kind of X settings I can use. Here (under
SuSE 11.1), my video hardwware is supported by "standard" drivers and I
like that better. But I haven't yet found how to boot the PAE kernel
over GRUB into other than 80 columns, 25 lines, 16 colours (or maybe 8
bg, 16 fg, blink).

Best regards,
Tony.

Regardless of whether you like them or not, framebuffer consoles can
display millions of colors, mplayer can play full color movies in them
(though it looks somewhat strange to see an mplayer window with no
window manager decorations pop up), and I've heard that fbiterm (a
terminal emulator that runs in the framebuffer console) can support
256 colors.
