Mike Beckerle closed DAFFODIL-576.
----------------------------------
Resolution: Not A Problem
Really a scallop library limitation.
> CLI: Gracefully handle trailing flags
> -------------------------------------

> Key: DAFFODIL-576
> URL: https://issues.apache.org/jira/browse/DAFFODIL-576
> Project: Daffodil
> Issue Type: Bug
> Components: CLI, Usability
> Affects Versions: s7
> Reporter: Jessie Chab
> Priority: Minor
> Labels: beginner
>
> I was running pcap tests with the CLI and I wanted to save the output to a
> file so I could copy it over to a TDML file. I added "-o outfile" to my
> command, not thinking about the fact that it came after the infile trailing
> argument. Depending on the file I was parsing I got one of the following
> errors:
> org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1;
> {color:red}Content is not allowed in prolog.{color}
> at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source)
> at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown
> Source)
> at
> edu.illinois.ncsa.daffodil.xml.DaffodilXMLLoader.loadXML(DaffodilXMLLoader.scala:435)
> at scala.xml.factory.XMLLoader$class.load(XMLLoader.scala:56)
> ........
> org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1;
> {color:red}Invalid byte 2 of 2-byte UTF-8 sequence.{color}
> at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source)

> at scala.xml.factory.XMLLoader$class.load(XMLLoader.scala:56)
> Would it be possible for the CLI to either acknowledge a flagless argument as
> an infile, so the arguments can be in any ordering, or to catch this kind of
> situation and alert the user that there cannot be arguments after the infile
> before trying to parse?
