Here's a slight improvement of the vimscript I sent earlier. This version
lets you operate on a range of lines and only defines itself if the vartabs
feature exists. I put this in a "autovts.vim" file in my .vim/plugin
directory. The argument that you can give to the AutoTabs command specifies
how many extra spaces you want between the fields.
if has("vartabs")
function! AutoVariableTabstop(line1,line2,...)
let extra = 0
if a:0 > 0
let extra = a:1
endif
let i = a:line1
let tabs = []
while i <= a:line2
let fields = split(getline(i),"\t",1)
let i = i + 1
let f = 0
while f < len(fields)
let l = strlen(fields[f])+1+extra
if (len(tabs) <= f)
call add(tabs,l)
else
if (l > tabs[f])
let tabs[f] = l
endif
endif
let f = f + 1
endwhile
endwhile
execute "set vts=" . join(tabs,",")
endfunction
command! -nargs=? -range=% AutoTabs call
AutoVariableTabstop(<line1>,<line2>,<args>)
endif
