Golang: extract data with Regex

Question

I\'m trying to extract whatever data inside ${}.

For example, the data extracted from this string should be abc.

git commit -m          


        

Answer 1

Because $, { and } all have special meaning in a regex and need to be backslashed to match those literal characters, because * doesn't work that way, and because you didn't actually include a capturing group for the data you want to capture. Try:

re := regexp.MustCompile(`\$\{.+?)\}`)
