Re: Set highlight colours according to screen

My local laptop monitor is....shall we say, "different" from an external

then use that conditional test to set the appropriate colour.

If you "extend" your monitor, then you can use the window position to check.

I extend mine above my existing monitor (instead of beside it).

These functions report negative values for me when I move it to the extended monitor.

getwinposx() < 0

getwinposy() < 0

You can simply check for a range of values.

I also wrote a mapping to toggle my Vim session back and forth between the monitors (if this helps):

if has("gui_running")

    " Reposition gvim when using the windows extended monitor

    " Top and bottom

    " Use negative values if screen is above main desktop.

    " Basically, position Vim and look at this output:

    " echo getwinposx() getwinposy()

    " nnoremap <Leader>fx :exec 'winpos '.(getwinposx()<0 ? '15' : '-15').' '.(getwinposy()<0 ? '17' : '-1183')<CR>

    nnoremap <Leader>fx <C-O>:exec 'winpos '.(getwinposx()<0 ? '15' : '15').' '.(getwinposy()<0 ? '40' : '-1192')<CR>

    " This version will change the font size (since the monitor is bigger) and move the screen.

    " Had to record the X and Y positions since set guifont= will cause the screen to move under certain cirumstances.

    nnoremap <Leader>fx :let winx = getwinposx()\|let winy = getwinposy()\|exec 'set guifont=Bitstream_Vera_Sans_Mono:h'.(winy<0 ? '11' : '11').':b:cANSI'\|echomsg 'executing winpos '.(winx<0 ? '15' : '15').' '.(winy<0 ? '40' : '-1192')\|exec 'winpos '.(winx<0 ? '15' : '15').' '.(winy<0 ? '40' : '-1192')<CR>

    " Move Vim left and right (assuming screen configuration)

    " nnoremap <Leader>fx :exec 'winpos '.(getwinposx()<1900 ? '2055' : '276').' 14'<CR>

    " nnoremap <Leader>fx <C-O>:exec 'winpos '.(getwinposx()<1900 ? '2055' : '276').' 14'<CR>

endif
