here what I am trying to do, a simple function to increment a global variable. It works fine.
let g:high_ind = 1
fun! IncHighlightInd()
let g:high_ind = (g:high_ind + 1) %10
return g:high_ind
endf
I want to use this variable in a map
map <C-h> :call IncHighlightInd() <CR> :Highlight g:high_ind <CR>
But g:high_ind
is not recognized as a variable. How to use this variable?
Or more interestingly, is it possible to do something like the below?
map <C-h> :Highlight IncHighlightInd() <CR>
You have to use :exe or c_CTRL-R_=:
nnoremap <c-h> :exe ":Highlight ".IncHighLightInd()<cr>
nnoremap <c-h> :Highlight <c-r>=IncHighLightInd()<cr><cr>
BTW, I suspect you should have a look at this page: Highlight multiple words on vim.wikia.
