Subject [jira] Commented: (PIG-139) Command line editing, history and more for Grunt
Date Fri, 18 Jul 2008 00:55:31 GMT

    [ https://issues.apache.org/jira/browse/PIG-139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12614593#action_12614593

Amir Youssefi commented on PIG-139:

Good move. It partially works:

Demonstrating by example: 

ARITY is in pig/branches/types/autocomplete

+ : It works when that's local dir.

- : It doesn't work when current directory is elsewhere and above is in Class Path (I used
java -cp ... to run)

+ :  src/org/apache/pig/tools/grunt/autocomplete works (e.g. LOAD or load which is not in
pig/branches/types/autocomplete) . 

+ : I see that you have case sensitivity so one has to have both LOAD and load there in keywords
list.  ARITY is in local autocomplete but not arity and only ARITY works. Good thing is that
user's preference is applied, meaning if user meant load or LOAD (s)he gets it in correct
case. Since some of the autocomplete cases (e.g. Piggy Bank classes) are case sensitive, having
case-sensitivity in output is definitely needed. We can add functionality of correct case
even though input is not correct case. I'm not sure if it worth the effort. Example: we could
convert math.floo<tab> to math.FLOOR and correct the case. Perhaps it would be better
to wrap it up for now.
