I'm using Exuberant Ctags to generate a tags file to use with Vim. However, in our project, we have javascript that makes remote procedure calls to the server (PHP). Functions like getUsers are thus called rpc_getUsers on the serverside. Is there a way to properly use things like ctrl+] to jump to the associated function on the serverside, assuming it's a standard prefix/list of prefixes?
Search for tags with prefixes in other language files
ctags;tags
You could use a mapping from Ctrl+] to a custom function, similar to the one described at :help CursorHold-example:A nice addition is to highlight the found tag, avoid the :ptag when thereis no word under the cursor, and a few other things: >  :au! CursorHold *.[ch] nested call PreviewWord()  :func PreviewWord()  :  if &previewwindow                   don't do this in the preview window  :    return  :  endif  :  let w = expand(<cword>)           get the word under cursor  :  if w =~ '\a'                        if the word contains a letter  :  :     Delete any existing highlight before showing another tag  :    silent! wincmd P                  jump to preview window  :    if &previewwindow                         if we really get there...  :      match none                      delete existing highlight  :      wincmd p                        back to old window  :    endif  :  :     Try displaying a matching tag for the word under the cursor  :    try  :       exe ptag  . w  :    catch  :      return  :    endtry  :  :    silent! wincmd P                  jump to preview window  :    if &previewwindow                 if we really get there...  :      if has(folding)  :        silent! .foldopen             don't want a closed fold  :      endif  :      call search($, b)           to end of previous line  :      let w = substitute(w, '\\', '\\\\', )  :      call search('\<\V' . w . '\>')  position cursor on match  :       Add a match highlight to the word at this position  :      hi previewWord term=bold ctermbg=green guibg=green  :      exe 'match previewWord \%' . line(.) .
