3 ways to split a string into a slice



Use the strings.Split function to split a string into its comma separated values.

s := strings.Split("a,b,c", ",")
// Output: [a b c]

To include the separators, use strings.SplitAfter. To split only the first n values, use strings.SplitN and strings.SplitAfterN.

White space

Use the strings.Fields function to split a string into substrings removing white space.

s := strings.Fields(" a \t b \n")
// Output: [a b]

General case

In more complicated situations, the Regexp.Split function might do the trick.
