REPL: scribe macro NPE when the scala source file is virtual

[Jamie Thompson]

Scala compiler can accept virtual source files, e.g. in the REPL (and e.g. a hypothetical improved Zinc implementation). In these cases the "jpath" of the SourceFile can be null, causing a crash:

scala> scribe.info("foo")
-- Error: ----------------------------------------------------------------------
 1 |scribe.info("foo")
   |                  ^
   |Exception occurred while executing macro expansion.

For these virtual files the name and path properties should still have values

@bishabosha thanks for pointing this out. This appears to be a bug in https://github.com/com-lihaoyi/sourcecode causing this, but see the issue I linked above to get this resolved.

@bishabosha This should be fixed in the latest release.
