CLONE -Line break in DSL isnot generated anymore since Drools 5.0.0 CR1
-----------------------------------------------------------------------
Key: JBRULES-2173
URL: https://jira.jboss.org/jira/browse/JBRULES-2173
Project: JBoss Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-compiler
Affects Versions: 5.0.0.CR1
Environment: jre6u12
eclipse 3.4
win xp
Reporter: Neil Wallace
Assignee: Edson Tirelli
Fix For: 5.0.1.FINAL
In Drools 4.0.7 and 5.0.0M5 it was possible to generate linebreaks using \n in an
dsl-File.
Since 5.0.0 CR1 this is no longer possible: the \n is simply converted to the letter n
which leads to compile-errors concerning the replaced code.
Example DSL:
# Test linebreak-bug since 5.0.0 CR1
[*][]only a simple test = System.out.println \n ("Did it generate a line
break?");
Example DSLR:
#created on: 12.03.2009
package linebreak
expander linebreakbug.dsl
rule "line break bugtest"
when
#conditions
then
only a simple test
end
This leads to the line
System.out.println n ("Did it generate a line break?");
Maybe this bug is related to https://jira.jboss.org/jira/browse/JBRULES-1970 where the
handling of #-Characters in DSL-Files had been fixed.
In my special case I'v got an workaround, but that's no workaround for anyone:
Using one DSLR I generate 2 Outputs:
a) using DSLR with dsl-file-A leads to "DLR"-Code: I don't need line breaks
here (today, but maybe next month?)
I don't care if the generated Code is nice or not and if the line is long or not.
The code works and is executed by the rules-engine. Everything fine here.
b) using DSLR with dsl-file-B leads to programming-code in another programming-language.
This Code is never executed in Drools, it is simply generated.
The result is taken an copied into the target-system. For that task I have written an own
plugin that does that stuff and works like a little post-processor.
So my workaround is to use my own "keyword" $CRLF in an DSL-File and - after the
generation that Drools does - replaced that with "\n".
Not where nice but simple...
