Support multiple formatters on a single buffer

[TamaMcGlinn]

I'm trying to run several different formatters on a single buffer when I save it. Something like:

  autocmd FileType cpp AutoFormatBuffer clang-format
  autocmd FileType cpp AutoFormatBuffer copyright

(which in fact only applies the last formatter given) I also tried:

  autocmd FileType cpp AutoFormatBuffer clang-format,copyright

But that doesn't apply either. :help AutoFormatBuffer didn't help me, but surely I'm not the only person who wants to apply two or more formatters?

The workaround is bit ugly, but hopefully it helps anyone coming to this issue in the meantime:

function! ApplyCppFormatters() abort
  execute 'FormatCode copyright'
  if expand('%:e') ==# 'h'
    execute 'FormatCode header_guards'
  endif
  execute 'FormatCode clang-format'
endfunction

augroup autoformat
  autocmd!
  autocmd BufWritePre *.cpp,*.h call ApplyCppFormatters()
augroup END

Yes, you're not alone! See #44. I'll merge these and post an update with some more details there.

  autocmd BufWritePre *.cpp,*.h call ApplyCppFormatters() | noautocmd write

BTW, isn't noautocmd write redundant since vim's already going to write the file after BufWritePre?

Correct, thank you! I had this because I had a different formatter which wasn't able to accept stdin, so it works on a post-write hook and then needs to write the file again:

autocmd BufWritePost *.ad[sb] Autoformat | noautocmd write
