Protect regular expression

[nz]

Hi

Lets say I have a string variable "term" from and I used it in bson.RegEx{Pattern:string(`^.*` + term + `.*`)}  is there a way to encode variable term so it does not interfere with the rest of the regular expression ? 

thanks

Hi nz,

There's no built in regular expression escaping right now, so you'll
need to study the rules and escape them yourself for the time being.
It's not a bad idea to have that as a standard feature, though.

Something quick I whipped together, looks like it should work to replace characters

re := regexp.MustCompile(`([-[\]{}()*+?.,\\^$|#\s])`)

fmt.Println(re.ReplaceAllString("foo.*", "\\$1"))
