I'd like to have vim highlight entire lines that match certain patterns. I can get all the text in a line to highlight (by doing syn match MyMatch "^.*text-to-match.*$"), but it always stops at the end of the text. I'd like to to continue to the end of the term, like highlighting CursorLine.
I've tried replacing $ with a \n^, hoping that would wrap it around. No change. (I didn't actually expect this would work, but there's no harm in trying.) I also tried adjusting the syn-pattern-offset (which I read about here: http://vimdoc.sourceforge.net/htmldoc/syntax.html#:syn-pattern). Long story short, adding he=he-5 will highlight 5 fewer characters, but he=he+5 doesn't show any extra characters because there aren't characters to highlight.
This is my first attempt at making a vim syntax and I'm relatively new to vim. Please be gentle and include explanations.
Thanks!
(edit: Forgot to include, this is a multiline highlight. That probably increases the complexity a bit.)
It's not very adaptive as the filename (buffer) and line to full row highlight needs to be explicitly identified, but apparently the sign command can be used:
It is possible to highlight an entire
line using the :sign mechanism.
An example can be found at :help
sign-commands
In a nutshell:
:sign define wholeline linehl=ErrorMsg
:sign place 1 name=wholeline line=123 file=thisfile.txt
Obviously, you should pick a higlight
group that changes the color of the
background for the linehl argument.

From the documentation on syn-pattern:
The highlighted area will never be
outside of the matched text.
I'd count myself surprised if you got this to work, but then again, Vim is always full of surprises.
could also try
:set cursorline
:set cursorcolumn
change colors like this:
:hi cursorline
:hi cursorcolumn
using the usual term=, ctermfg=, ctermbg= etc

VIM Highlight the whole current line

I am pretty noob at Vim still, pardon my ignorance
"Boundary" whitespace is any whitespace except single spaces between words, paraphrasing from VSCode docs:
I want to mimic this same behavior in Vim (ideally with no plugins).
An example of how this feature looks in VSCode:
There aren't many resources that I found on this topic. There is Render space if it have multi space in Vim, which addresses this exact same feature (previous example image shown is from that question), but the provided solution does not work exactly as expected.
This is an example of how boundary whitespaces look after trying out that stackoverflow solution:
While the '·' character is shown when there are 2 or more spaces in a row, which is desired, they are also shown highlighted, which is not what I expected
Moreover, if I place the cursor on a line that contains consecutive spaces, they disappear (or are highlighted into invisibility, whatever is happening that renders them invisible)
Excuse my newbie comments in my .vimrc; the rest of the file is commented out
This is another example, in VSCode, of the desired behavior:
Am I missing something from that previous question? Is the highlighting of whitespaces normal or a different issue on its own? Thanks in advance!
The feature you are looking for can be enabled with :help 'list' and customized with :help 'listchars':
The result above can be obtained by adding the following lines to your vimrc:
set list
set listchars=eol:↵,lead:·
If your color scheme makes those characters too visible, you can override its NonText and SpecialKey highlight groups (mentioned in :help 'listchars') to make them more bearable. For example:
augroup MyColors
autocmd!
autocmd ColorScheme * hi NonText ctermfg=235 | hi SpecialKey ctermfg=235
augroup END
colorscheme foobar
Note that listchars was more limited at the time the linked question was answered so, while it was more or less valid at the time, it is no longer necessary to use the conceal feature for this.
I use the vim-fugitive plugin to check git diff. The coloring scheme to highlight the code changes does not compliment my solarized background. I am not able to see the commands to change the coloring scheme of Gdif. Could anyone help me changing the coloring scheme?
From :help :diffupdate:
|hl-DiffAdd| DiffAdd Added (inserted) lines. These lines exist in
this buffer but not in another.
|hl-DiffChange| DiffChange Changed lines.
|hl-DiffText| DiffText Changed text inside a Changed line. Vim
finds the first character that is different,
and the last character that is different
(searching from the end of the line). The
text in between is highlighted. This means
that parts in the middle that are still the
same are highlighted anyway. Only "iwhite" of
'diffopt' is used here.
|hl-DiffDelete| DiffDelete Deleted lines. Also called filler lines,
because they don't really exist in this
buffer.
So, for example, something like
:highlight DiffAdd ctermfg=253 ctermbg=237 guifg=#dadada guibg=#3a3a3a
in your colorscheme should change the colour of the added lines.
When I work in a fast paced with vim, one of the recurring annoyance is highlighting of {} or {} or []. When the parenthesis or brackets are adjacent to each other, it takes me a second (yes a whole second!) to figure out where the focus is. I do not like having to rely on the blinking and I still want the matching paren/bracket to be highlighted. So how can I remove just the highlighting for the current paren/bracket?
:hi MatchParen ctermbg=black guibg=black
show match is ok, but the highlight was driving me nutz. The above turns the highight black so you don't see it when editor has a black background
:NoMatchParen
type :help matchparen for more help on this .
this functionnality is really useful for me, so maybe you can look at the doc a little and find a way to hightlight the matching pair in a different color (or just underline it for example)
What you are looking is
set noshowmatch
to be set in vimrc
I have commented out the
"hi Fold …
line in my current vim-colorscheme (xoria256 modified), but when I edit there is still (an even uglier) syntax highlight. I looked in the syntax file for the specific filetype - but there was no Fold highlight too. Now I don't know where to look for a "default syntax highlighting".
In the end I just want to have folds with foreground color as specified by syntax and just the background changed. Maybe I am thinking to much and there is a plain easy way to do that.
ps: i tried to leave off the guifg and ctermfg part to no success.
I'm afraid that doing so is not possible (at least without touching Vim's source code). The text in the fold line is computed and not part of your file, which means that it will not be processed like the rest of the text/code and it will be only applied the Folded highlighting group. That's why you get a single foreground color when you comment out the hi Folded line.
Is it possible to not display a ~ for blank lines in Vim?
This confuses Mac Vim's scrollbar, and I quite don't like these tildes.
:hi NonText guifg=bg
That command should set the color of non text characters to be the same as the background color.
Vim 8.x:
You can now change the color just for the end of the buffer ~:
highlight EndOfBuffer ctermfg=black ctermbg=black
See changelog for Vim 8.x.
As jamessan said, you can’t disable them. The scrolling behavior isn’t specific to MacVim, either — it works the same way in the terminal and in gvim:
Instead of seeing this as a problem, what you should do is learn to see this as part of Vim’s flexibility. For example, you can use the zt command to scroll the current line to the top of the screen, regardless of where in the file it is. This can make it easier to write macros that do some work and then scroll back to where you were. The commands <C-E> and <C-Y> are made simpler because of this, as is the 'scrolloffset' option.
If you must, retrain your brain to think of Vim’s scrollbar as mapping to which line is on top, instead of which screenful is visible.
For NeoVim, you can set the fillchars value for eob to a space character and that will effectively hide it. (This might not work for plain Vim).
In Lua (Nvim 0.5+):
vim.wo.fillchars='eob: '
In VimScript:
set fillchars=eob:\
Note: Calling the above will override your fillchars value for other items as well (if set), so use this as a reference to set multiple values together:
set fillchars=eob:\ ,fold:\ ,vert:\│
Or use set fillchars+=... to append it your existing values.
You can't disable them, but you can change your colorscheme such that the NonText highlight group is colored the same as the Normal highlight group. However, this affects more than just the end of document tildes.
I doubt that it's actually "confusing" MacVim's scrollbar and if it is, then that's a bug in the patching that MacVim does.
The tilde ~ characters are meant to remind the user that those lines are not part of buffer content.
The above highlight trick will hide the ~ character, but it is still there. For some terminals, this may not even work. If you happen to be a Neovim user, you can use fillchars option to change the end of buffer symbol like this:
set fillchars=fold:\ ,vert:\│,eob:\ ,msgsep:‾
This will use space instead of ~ for end of buffer, effectively hiding the annoying ~.
