Replacing quote marks around strings in Vim?

Question

I have something akin to and need to change the single quotation marks to double quotation marks. I tried :s/\\\'.*\\\'/\

Answer 1

There's also surround.vim, if you're looking to do this fairly often. You'd use cs'" to change surrounding quotes.

Answer 2

You need to use groupings:

:s/\'\(.*\)\'/\"\1\"

This way argument 1 (ie, \1) will correspond to whatever is delimited by \( and \).

Answer 3

You've got the right idea -- you want to have "\1" as your replace clause, but you need to put the "Hello There" part in capture group 1 first (0 is the entire match). Try:

:%/'\(.*\)'/"\1"

Answer 4

You need to put round brackets around the part of the expression you wish to capture.

s/\'\(.*\)\'/"\1"/

But, you might have problems with unintentional matching. Might you be able to simply replace any single quotes with double quotes in your file?

Answer 5

Just an FYI - to replace all double quotes with single, this is the correct regexp - based on rayd09's example above

:%s/"\([^"]*\)"/'\1'/g

Answer 6

%s/'\([^']*\)'/"\1"/g

You will want to use [^']* instead of .* otherwise

'apples' are 'red' would get converted to "apples' are 'red"
