### Version 5.1.0 ### What happened? Parsing double and decimal numbers in turtle format can fail, even if the numbers are according to the grammar. This can happen, if the numbers have a sign but not a leading '0' before a dot, e.g. as in the following example: ``` <iri1> <iri2> -.2e3 . ``` I load it using `RDFDataMgr.loadDataset(<path>)` This leads to an exception. I suspect the problem to be in [TokenizerText.java, line 450](https://github.com/apache/jena/blob/def3fdd1dc1abaea5fd39ecfd01bb2d531d27ceb/jena-arq/src/main/java/org/apache/jena/riot/tokens/TokenizerText.java#L450), where it is only checked if a leading sign is followed by a digit, not by a dot, to decide if the following symbols are part of the token (also the comment in [line 429](https://github.com/apache/jena/blob/def3fdd1dc1abaea5fd39ecfd01bb2d531d27ceb/jena-arq/src/main/java/org/apache/jena/riot/tokens/TokenizerText.java#L429) in the same file suggests that this is the misunderstanding). Note: The turtle grammar in [turtle.jj](https://github.com/apache/jena/blob/main/jena-arq/Grammar/Turtle/turtle.jj) seems to be correct w.r.t. the shape of doubles and decimals. ### Relevant output and stacktrace ```shell Exception in thread "main" org.apache.jena.riot.RiotException: [line: 1, col: 15] Unrecognized (expected an RDF Term): [MINUS] at org.apache.jena.riot.system.ErrorHandlerFactory$ErrorHandlerStd.fatal(ErrorHandlerFactory.java:155) at org.apache.jena.riot.lang.LangEngine.raiseException(LangEngine.java:148) at org.apache.jena.riot.lang.LangEngine.exceptionDirect(LangEngine.java:143) at org.apache.jena.riot.lang.LangEngine.exception(LangEngine.java:137) at org.apache.jena.riot.lang.LangTurtleBase.triplesNodeCompound(LangTurtleBase.java:489) at org.apache.jena.riot.lang.LangTurtleBase.triplesNode(LangTurtleBase.java:469) at org.apache.jena.riot.lang.LangTurtleBase.objectList(LangTurtleBase.java:419) at org.apache.jena.riot.lang.LangTurtleBase.predicateObjectItem(LangTurtleBase.java:352) at org.apache.jena.riot.lang.LangTurtleBase.predicateObjectList(LangTurtleBase.java:333) at org.apache.jena.riot.lang.LangTurtleBase.triples(LangTurtleBase.java:314) at org.apache.jena.riot.lang.LangTurtleBase.triplesSameSubject(LangTurtleBase.java:178) at org.apache.jena.riot.lang.LangTurtle.oneTopLevelElement(LangTurtle.java:46) at org.apache.jena.riot.lang.LangTurtleBase.runParser(LangTurtleBase.java:79) at org.apache.jena.riot.lang.LangBase.parse(LangBase.java:43) at org.apache.jena.riot.lang.RiotParsers$AbstractReaderRIOTLang.read(RiotParsers.java:133) at org.apache.jena.riot.lang.RiotParsers$AbstractReaderRIOTLang.read(RiotParsers.java:91) at org.apache.jena.riot.RDFParser.read(RDFParser.java:452) at org.apache.jena.riot.RDFParser.parseURI(RDFParser.java:421) at org.apache.jena.riot.RDFParser.parse(RDFParser.java:383) at org.apache.jena.riot.RDFParserBuilder.parse(RDFParserBuilder.java:547) at org.apache.jena.riot.RDFDataMgr.parseFromURI(RDFDataMgr.java:564) at org.apache.jena.riot.RDFDataMgr.read(RDFDataMgr.java:429) at org.apache.jena.riot.RDFDataMgr.read(RDFDataMgr.java:406) at org.apache.jena.riot.RDFDataMgr.read(RDFDataMgr.java:386) at org.apache.jena.riot.RDFDataMgr.read(RDFDataMgr.java:377) at org.apache.jena.riot.RDFDataMgr.loadDataset(RDFDataMgr.java:337) ``` ### Are you interested in making a pull request?
