[jboss-jira] [JBoss JIRA] Commented: (LOGTOOL-20) Detect parameters being inconsistent with log message template

[James Perkins (JIRA)]

    [ https://issues.jboss.org/browse/LOGTOOL-20?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12608683#comment-12608683 ] 

James Perkins commented on LOGTOOL-20:
--------------------------------------

We will definitely add parameter count checking. I'm currently looking into the best approach to deal with type consistency. My guess is it's not impossible, but might take some time to implement.

> In both Infinispan and Hibernate we had reports of issues following the same patterns, as in code like:
> {code}
> @LogMessage(level = ERROR)
> @Message(id = 21, value = "Unable to synchronize source of %s for entity %s")
> void unableToSynchronizeSource(String indexName, @Cause Exception e);
> {code}
> People might do mistakes in the string template, forget to pass enough parameters, or not use the positional _%1$s_ variants. We can hardly write tests to cover all log messages, while I think it would be quite cool if the annotation processor could verify messages consistency with parameters at compile time.
> It would be just awesome if it could check for type consistency as well.
