[jira] [Commented] (CASSANDRA-12897) Move cqlsh syntax rules into separate module and allow easier customization

    [ https://issues.apache.org/jira/browse/CASSANDRA-12897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15662526#comment-15662526 ] 

Stefania commented on CASSANDRA-12897:
--------------------------------------

Patch LGTM. 

There are two duplicate lines [here|https://github.com/apache/cassandra/compare/cassandra-3.X...nastra:CASSANDRA-12897#diff-321fbab92058e0e947cfbd0c5383c610R220] and [here|https://github.com/apache/cassandra/compare/cassandra-3.X...nastra:CASSANDRA-12897#diff-321fbab92058e0e947cfbd0c5383c610R230], which I've already fixed in the final patch to be committed.

I'm running the clqsh specific tests, because the ordinary dtests do not include cqlshlib unit tests, just to ensure nothing got broken there:

> At the moment the entire cqlsh syntax rules are defined in one single field in https://github.com/apache/cassandra/blob/13b7362494c4c0ff3c5ce80b8e7ee7fe64d65785/bin/cqlsh.py#L313-L426.
> It would be easier if every syntax rule would be stored in its own field for easier extensibility / customizability.
> It probably also makes sense to move the relevant *cqlsh* syntax rules and syntax completer into a separate *cqlshhandling.py* module because *cqlsh.py* in itself is huge.
