Subject [jira] [Commented] (TINKERPOP-1157) gremlin.sh should allow you to execute a script and go interactive on error or completion
Date Thu, 07 Apr 2016 23:41:25 GMT

    [ https://issues.apache.org/jira/browse/TINKERPOP-1157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15231344#comment-15231344

Ariel Weisberg commented on TINKERPOP-1157:
-------------------------------------------

If you start gremlin.sh and pass it as a parameter a file to execute I would like it to stop
upon reaching the first parse error or uncaught exception and become an interactive shell
so I can inspect the state of the program.

Something like {{python -i}}
{noformat}
     When  a  script  is  passed as first argument or the -c option is used, enter interactive
mode after executing the script or the command.  It does not read the
     $PYTHONSTARTUP file.  This can be useful to inspect global variables or a stack trace
when a script raises an exception.
{noformat}

Maybe something does exist for [groovy 2.4?|https://groups.google.com/forum/#!topic/groovy-user/LaSEv3Sxivw]

>             Project: TinkerPop
>          Issue Type: Improvement
>          Components: console
>    Affects Versions: 3.1.1-incubating
>            Reporter: Ariel Weisberg

> This may be specific to my workflow, but generally when I am learning/experimenting with
a REPL I have one window open with my script and another console open that I use to run it.
I like to restart the REPL every time to avoid lingering state.
> I would like to be able to drop back to interactive executing a script once it completes
and my data is loaded and any queries I may have run are complete and I can inspect the results.
> On error I want to drop to interactive so I can inspect the current state at the time
the error occurred.
