Question

Assuming I have the following options Hash as an argument to a method in Ruby 1.9.x:

my_method :arg1,
  some_option: "value 1"
  some_other_option:true
  option_three: 123

Using the Tabular VIM plugin, what would the regular expression be to get the options Hash align like so:

my_method :arg1,
  some_option:       "value 1"
  some_other_option: true
  option_three:      123

The : has to stay attached to the key, unlike with, for example, JSON.

Perhaps a more visually appealing style would be this instead, which looks more aligned:

my_method :arg1,
        some_option: "value 1"
  some_other_option: true
       option_three: 123

Does anyone by any chance know how to accomplish either of these alignments using Tabular?

Thanks!

Answer 1

In order to get the first alignment, one can use the command

:Tab/\w:\zs/l0l1

For aligning hash keys to the right, it seems inevitable to select
only the lines containing them before applying a :Tabular command,

:Tab/\w:\zs/r0l1l0
