I'm trying to bring to work together 3 things: ConEmu, Cygwin and vim. The vim in question is not Cygwin vim, but the native Windows vim from gvim package (chosen because Cygwin vim does not support xterm 256 colors). 256-color syntax highlighting seems to work after I followed the instructions on StackOverflow, but I cannot solve another problem.

Cygwin vim works fine with alternate screens: when I exit it, the screen content is cleared and I can see my command history back again. Windows vim does not: when I exit it, the command prompt appears underneath the page of former vim content. This question has been asked several times on StackOverflow and SuperUser: here, here, here and here. However, none of the solutions in these questions seem to work in ConEmu/Cygwin. I tried:

  • setting t_ti and t_te in my .vimrc as follows:

    let &t_ti="\e[?47h"
let &t_te="\e[?47l"

  • or:

    let &t_ti="\e[?1049h"
let &t_te="\e[?1049l"

  • enabling altscreen on in .screenrc. I'm not sure that it was supposed to have any effect at all, since I didn't even have screen installed in Cygwin. Installing it didn't change anything, though. Explicitly launching vim with screen brings weird results: half of escape sequences and codes and broken, not every keypress is recognized, and the console dimensions are ~80x40 regardless of screen arguments.

My $TERM in vim currently is xterm, as it has been set in .vimrc config required to enable 256 color support in ConEmu. However, sending xterm-like escape sequences does not seem to clear screen whatsoever.

I'd very glad for any help with this issue.

AFAIK vim (Windows version) does not post to terminal enter/leave alternative mode sequences. Don't know how mintty deals with it, still investigating.

Try setting this in your .vimrc, which also enables the scroll wheel in vim.
This came from http://conemu.github.io/en/Whats_New.html, the build 150316 notes. It seemed to finally fix this issue for me.

""""""""""""""""""""""""""""""""""""""
" let mouse wheel scroll file contents
""""""""""""""""""""""""""""""""""""""
if !has("gui_running")
    set term=xterm
    set mouse=a
    set nocompatible
    inoremap <Esc>[62~ <C-X><C-E>
    inoremap <Esc>[63~ <C-X><C-Y>
    nnoremap <Esc>[62~ <C-E>
    nnoremap <Esc>[63~ <C-Y>
endif
