Auto-align on equal signs (=) using Tabularize.

cucumbertables.vim

inoremap <silent> = =<Esc>:call <SID>ealign()<CR>a
function! s:ealign()
  let p = '^.*=\s.*$'
  if exists(':Tabularize') && getline('.') =~# '^.*=' && (getline(line('.')-1) =~# p || getline(line('.')+1) =~# p)
    let column = strlen(substitute(getline('.')[0:col('.')],'[^=]','','g'))
    let position = strlen(matchstr(getline('.')[0:col('.')],'.*=\s*\zs.*'))
    Tabularize/=/l1
    normal! 0
    call search(repeat('[^=]*=',column).'\s\{-\}'.repeat('.',position),'ce',line('.'))
  endif
endfunction

I replaced line 3 by :

let p = '^.*=[^>]*$'

to match = characters but not =>

I actually did that (or something similar, with the same effect) to my own version I'm using. I didn't think to update it here though. Thanks for the update :) Edit: Updated the gist to reflect the version I have. This will make it work just with = signs, not => or whatever.

Thanks very much for this - one problem I'm finding is that when it carries out the Tabularize the cursor moves to the beginning of the line. Do you know a way around this?
