staticinherited

This function parses the specified name and optional parameters and create a corresponding validator for this option.

The name_and_params string can be defined as:

<validator-name>(<param1>, <param2>, ...)

advgetopt::validator_email::name

virtual std::string name() const override

Return the name of this validator.

The list of parameters is optional. There may be an empty, just one, or any number of parameters. How the parameters are parsed is left to the validator to decide.

If the input string is empty, the current validator, if one is installed, gets removed.

The complete grammar of the name_and_params name and parameters can be written as a comma separated list of function calls, we have a special case for regex which do not require the function call. thing is pretty much anything other than the few special characters (comma, space, parenthesis, and quotes). To include a special character in thing either use a string or escape the character.

validator_list: name_and_params
              | name_and_params ',' validator_list
 
name_and_params: name '(' params ')'
               | '/' ... '/'              // regex special case
 
name: [a-zA-Z_][a-zA-Z_0-9]*
 
params: (thing - [,()'" ])
      | '\'' (thing - '\'') '\''
      | '"' (thing - '"') '"'
 
thing: [^ -~]*
     | '\\' [ -~]
