Conditional replace in vim

Question

I\'d like do use vim search-and-replace to replace all \" with \' and vice-versa. Is there a way to achieve this in one step? I\'m thinking of something like this:

Answer 1

Probably the laziest/easiest way:

  :%s/'/__/g | %s/"/'/g | %s/__/"/g

Three basic steps combined into one line:

1. convert ' to __ (or something random)
2. convert " to '
3. convert __ to "

Then combine them with the | symbol.

I'm sure some vim wizards will have a better solution, but that worked for me.
