How do I Escape Strings for Go Regular Expressions?

Escaping Strings in Go Regular Expressions

In Go, it may be necessary to escape characters in a string when using it in a regular expression. For instance, a string with periods and dashes may require escaping to prevent unexpected matches.

Using regexp.QuoteMeta

Fortunately, Go provides the regexp.QuoteMeta function that effectively escapes all special characters in a string, rendering it safe for use in regular expressions. Here's how it works:

import "regexp"

pattern := "^(@|\s)*" + regexp.QuoteMeta("{string}") + "[:?]$"

In this example, the string {string} would be dynamically defined and could contain characters such as periods or dashes. By applying regexp.QuoteMeta, all special characters within {string} will be escaped, ensuring that the regular expression pattern correctly matches the intended input.
