public class ConfigurableParserWithRange
extends ConfigurableParser

A modified version of the StandardConfigurableParser which includes a grammar matcher for matching lists [1,2,3] and ranges [1..10]. It also uses a custom pattern for matching numbers which with prevents confusions with the defaults range operator symbol ...

The symbol used for the range operator is specified in the constructor, other standard symbols ( ) [ ] , are read from the resource bundle.

The full confurations is like

String lbracket = "(";
String rbracket = "(";
String lsqbracket = "[";
String rsqbracket = "]";
String seperator = ",";
this.addHashComments();
this.addSlashComments();
this.addSingleQuoteStrings();
this.addDoubleQuoteStrings();
this.addWhiteSpace();
this.addTokenMatcher(
    new NumberTokenMatcher("((\\d+\\.\\d+)|(\\d+\\.(?!\\.))|(\\.\\d+)|(\\d+))(?:[eE][+-]?\\d+)?"));
this.addSymbols(lbracket, rbracket, lsqbracket, rsqbracket, seperator, rangeSymbols);
this.setImplicitMultiplicationSymbols(lbracket, lsqbracket);
this.addOperatorTokenMatcher();
this.addIdentifiers();
this.addSemiColonTerminator();
this.addWhiteSpaceCommentFilter();
this.addBracketMatcher(lbracket, rbracket);
this.addFunctionMatcher(lbracket, rbracket, seperator);
this.addGrammarMatcher(
    new ListOrRangeGrammarMatcher(
        this.getSymbolToken(lsqbracket),
        this.getSymbolToken(rsqbracket),
        this.getSymbolToken(seperator),
         this.getSymbolToken(rangeSymbols)
    ));
this.addArrayAccessMatcher(lsqbracket, rsqbracket);
