lining up function parameter lists with vim

Question

When defining or calling functions with enough arguments to span multiple lines, I want vim to line them up. For example,

def myfunction(arg1, arg2, arg, ...         


        

Answer 1

I believe you have to issue the command:

:set cino=(0

This is when using cindent of course.

edit: I missed "set"

Answer 2

Try the Align http://www.vim.org/scripts/script.php?script_id=294 and AutoAlign http://www.vim.org/scripts/script.php?script_id=884 scripts.

Answer 3

The previous poster had it, but forgot the set

:set cino=(0<Enter>

From :help cinoptions-values

The 'cinoptions' option sets how Vim performs indentation.  In the list below,
"N" represents a number of your choice (the number can be negative).  When
there is an 's' after the number, Vim multiplies the number by 'shiftwidth':
"1s" is 'shiftwidth', "2s" is two times 'shiftwidth', etc.  You can use a
decimal point, too: "-0.5s" is minus half a 'shiftwidth'.  The examples below
assume a 'shiftwidth' of 4.

...

    (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.
          (default 'shiftwidth' * 2).

            cino=                     cino=(0 >
              if (c1 && (c2 ||          if (c1 && (c2 ||
                          c3))                     c3))
                  foo;                      foo;
              if (c1 &&                 if (c1 &&
                      (c2 || c3))           (c2 || c3))
                 {                         {

Answer 4

you might get some good mileage out of using a language-specific external tool as a Vim filter. for example, if you can write a Perltidy config file to generate the formatting you want (it looks like you would want the -lp -vtc=2 flags), you can then pipe your existing Vim buffer through it with

:!/path/to/tidy -config /path/to/configfile

if you're going to be running this sort of command frequently, you can define an command by putting something like the following in your .vimrc:

command -range=% Tidy <line1>,<line2>!/path/to/tidy -config /path/to/configfile
