Description
In Go, it is better to avoid using double backslashes (\\) in regular expressions and instead use raw string literals (enclosed by backticks) to define regular expressions.
When using double backslashes, each backslash has a special meaning and needs to be escaped. This can lead to confusion and make regular expressions harder to read and understand.
Using raw string literals with backticks, on the other hand, treats backslashes as regular characters and avoids the need for escaping. This simplifies the expression and makes it more readable.
Non-Compliant Code Examples
func main () {
regexp.Compile("\\A(\\w+) total: items \\d+\\n\\z")
}
Compliant Code Examples
func main () {
regexp.Compile(`\A(\w+) total: items \d+\n\z`)
}
