substitute 'which apt' to $(which apt)

Question

i want to substitute the text 'which apt' to $(which apt).

:s/'\&.*'/$(\0) 

does substitute to $('which apt'). How can i leave those single quotes out on the substitution, so that just $(..) appears?

---

EDIT

:s/'\zs\&.*\ze'/$(\0)

results in $('which apt)'. Although the regex should match any character between the two ', as i marked them as outside of the selection. i don't know if i did sth wrong?

Answer 1

:s/'\(.\{-}\)'/$(\1)/g

Search part:

'            single quote
 \(.\{-}\)   any character — . —, as few as possible — \{-} —,
             captured for reuse in the replacement — \(...\) —
          '  single quote

Replacement part:

$(           replace the first quote
  \1         reuse the capture group
    )        replace the second quote
