How can I CamelCase-enable Vim search?
The described functionality can be easily implemented by means of Vimscript. Let us consider the following custom mappings.
nnoremap <expr> <leader>/ SearchCamelCase('/')
nnoremap <expr> <leader>? SearchCamelCase('?')
function! SearchCamelCase(dir)
call inputsave()
let ab = input(a:dir)
call inputrestore()
let l = filter(split(toupper(ab), '\zs'), 'v:val =~ "\\w"')
if len(l) > 0
let l[0] = '[' . l[0] . tolower(l[0]) . ']'
end
let @/ = '\C\<' . join(map(l, 'v:val . "[0-9a-z_]*"'), '') . '\>'
return a:dir . "\r"
endfunction
