search & replace: how to add a line feed to break up a line?

Question

So, I have the following line where I would like to find all the {#}= and put them on a new line. Of course there can be more then 9 value entries and there is more text on the line, so I am thinking of looking for something like comma, space, one or more digits, and finally the equal sign, then add a line feed between the comma and the space.

The question is: how do I do that in vi across multiple lines?

  sion] ],{1=ValueEntry, 2=ValueEntry, 3=ValueEntry, 4=ValueEntry, 5=ValueEntry, 6=ValueEntry, 7=ValueEntry, 8=ValueEntry}]

  sion] ],{1=ValueEntry, 
  2=ValueEntry, 
  3=ValueEntry, 
  4=ValueEntry, 
  5=ValueEntry, 
  6=ValueEntry, 
  7=ValueEntry, 
  8=ValueEntry}]

Answer 1

You can add a line break by using the atom \r in the replacement part of the :s command (while in the pattern part, you would need to use \n to match a line break).

That allows to split your string using the following command:

:s/,\ze \d\+=/&\r/g

That is search for a comma (and end the match there), followed by a space, at least one number and a = and replace the comma in this case with itself (using the special atom & which corresponds to the complete match) followed by a line break (\r).
