[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2041) .drl file ending in a single line comment w/o EOL not accepted

    [ https://jira.jboss.org/jira/browse/JBRULES-2041?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12461122#action_12461122 ]

----------------------------------------

Hi Wolfgang,

I am trying to reproduce this problem with current trunk, but I am unable to. My test file looks like this:

-------------------- BEGIN ---------------------
#### a comment
// another comment
package org.drools

// another comment
# ### one more

rule "test something"
    when
      p: Person( street == "Low" && sss[1] == 234 )
    then
end

# comment in the last line without EOL    
-------------------- END --------------------------

Note that there is no EOL in the comment in the last line. Any tip on reproducing the problem?

Thanks,
 Edson

> If the last line on some .drl file is a single line comment without EOL the compiler reports an error:
> Error message:
> [103,7]: [ERR 101] Line 103:7 no viable alternative at input ''
> I guess the DRL.g will have to provide the alternative (EOL|EOF) in both STYLE_SINGLE_LINE_COMMENT rules.
