I currently use astyle -A8 -t8 -p -j <filename> to format the code in my C project.

Is there a way to configure my .vimrc to follow the continuation line format that the above demands? For example astyle formats the below function call:


(which is the default indentation when I hit Enter) as


I saw in cinoptions-values there was something close:

+N    Indent a continuation line (a line that spills onto the next)
      inside a function N additional characters.  (default
       Outside of a function, when the previous line ended in a
       backslash, the 2 * N is used.

        cino=             cino=+10 >
          a = b + 9 *       a = b + 9 *
              c;                      c;

But that only aligns to a specific number of spaces. Is there a way to align it like the astyle example above?

The option you're looking for is set cino+=(0

(N    When in unclosed parentheses, indent N characters from the line
      with the unclosed parentheses.  Add a 'shiftwidth' for every
      unclosed parentheses.  When N is 0 or the unclosed parentheses
      is the first non-white character in its line, line up with the
      next non-white character after the unclosed parentheses.
  • This is almost exactly what I need... but is there a way to not insert a 'shiftwidth' and instead just insert aligning spaces?

  • Exactly as in my answer: set cino+=(0. Does this not work?

  • Ah I should clarify that I use tabs for C with the following: autocmd Filetype cType setlocal ts=4 sts=4 sw=4. I just tried it with spaces and that's why there's an extra 'shiftwidth'. Is there a way to make custom cinoptions?
