validateIdent

string validateIdent()(string str,  string additional_chars =  "_",  string entity_name =  "An identifier",  bool  no_number_start =  true)

Validates an identifier string as used in most programming languages.

The identifier must begin with a letter or with any of the additional_chars and may contain only ASCII letters and digits and any of the additional_chars.

Invalid identifiers will cause an exception with the error description to be thrown.

bool validateIdent(R)(ref  R error_sink,  string str,  string additional_chars =  "_",  string entity_name =  "An identifier",  bool  no_number_start =  true) if (isOutputRange!(R,  char))
