The following small piece changes the color of the statusline when you enter insert mode, and when you leave insert mode. There are no mapping keys or new commands to remember, it works totally automatically.
The color codes below are Green in normal mode, and Magenta in insert mode. If you like other colors, just change them.
" first, enable status line always set laststatus=2 " now set it up to change the status line based on mode if version >= 700 au InsertEnter * hi StatusLine term=reverse ctermbg=5 gui=undercurl guisp=Magenta au InsertLeave * hi StatusLine term=reverse ctermfg=0 ctermbg=2 gui=bold,reverse endif
If you want a different color based on the kind of insert mode you are in (i.e. insert, replace, or virtual insert), then you can use the
v:insertmode variable during the InsertEnter event execution to do something different in each mode. For example:
function! InsertStatuslineColor(mode) if a:mode == 'i' hi statusline guibg=magenta elseif a:mode == 'r' hi statusline guibg=blue else hi statusline guibg=red endif endfunction au InsertEnter * call InsertStatuslineColor(v:insertmode) au InsertLeave * hi statusline guibg=green " default the statusline to green when entering Vim hi statusline guibg=green
- :help 'showmode' for another way to indicate mode
- :help hl-ModeMsg if you want to change the color of the above
- There is the SmartusLine plugin that kind-of does what is explained in this page.
- The StatusLineHighlight plugin does not indicate the mode, but the buffer state (modified, readonly, unmodifiable, special non-file "scratch") / window (is preview window) by changing the highlighting of the window's status line.
This works when I enter insert mode for the first time and changes the colours properly when i leave insert mode, however after that the colour of the status line stays the same regardless of what mode I am currently in. Could it be something to do with other Vim settings?
- Which script are you using? I haven't tried either, but at a quick glance it looks like the second should work, but I'm not as certain about the first. The second sets the same property differently depending on mode, but the first does not have much overlap between the settings changed when switching modes. --Fritzophrenic 15:18, January 28, 2010 (UTC)
hi CursorLine ctermbg=green cterm=none au InsertEnter * set cursorline au InsertLeave * set nocursorline
The method of changing the statusline color works well, except it does not change the statusline to green when you exit insert mode using ^C, (as insertleave is not generated). I was thinking that you could change things so ^C changed the statusline color to green then called the ^C functionality, but I don't see how to do that with imap.
You can do the Ctrl-C remapping via inoremap, like so:
inoremap <c-c> <c-o>:hi statusline guibg=green<cr><c-c>
Thanks, incorporating all the above to provide a cut and paste solution:
