Hello! Got some questions about named groups:
"Group names must be valid lexical identifiers, and each group name must be defined only once within a regular expression." 1. Is this meant to indicate that regex add their own lexical scopes; partake in the lexical scope of their containing function if any; that the identifier must be unique within the regex and that that null, true, false, this etc. that are reserved keywords cannot be used (i.e. the Identifier construct); or just that they need to conform to the identifier syntax but reserved keywords are allowed (i.e. the IdentifierName construct)? 2. Can (?P=varname) refer to a lexical variable varname from a containing scope, or just to groups within the regex itself? 3. If it can refer to a variable in a containing scope, what constraints are put on the variable type, what conversions are made, etc? -- David "liorean" Andersson _______________________________________________ Es4-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es4-discuss
