I have something akin to and need to change the single quotation marks to double quotation marks. I tried :s/\\\'.*\\\'/\
:s/\\\'.*\\\'/\
%s/'\([^']*\)'/"\1"/g
You will want to use [^']* instead of .* otherwise
[^']*
.*
'apples' are 'red' would get converted to "apples' are 'red"
'apples' are 'red'
"apples' are 'red"
