I have, at long last, overcome my disinclination against spreadsheets and
played around a bit.
As one of the incentives (perhaps the main one) for this kind of rule
authoring appears to be a "syntax" cushioning by spreadsheet entries, I feel
that additional simplifications might be appreciated. Therefore, I have
modified some classes in org.drools.decisiontable.parser, to achieve the
following, in the area of RuleSet entries:
- All entries are now repeatable, either by adding more cells to the
right of "import" than just one (with a comma-separated list) or by writing
more that one "Import" row.
- Same for "Variables", "Functions" and "Queries".
- All tags ("Import",...) are case insensitive and immune against leading
and trailing spaces.
- Some user errors don't cause NPE; they throw an exception with an
Opinions, please, and should I just release this, or would someone care to
