Re: [Neo4j] Neo4j server - Gremlin plugin - line break in script
Guillaume,
I added a test to the Gremlin test, which works, see
https://github.com/neo4j/gremlin-plugin/blob/master/src/test/java/org/neo4j/server/plugin/gremlin/GremlinPluginTest.java#L238
However, I suspect the REST system to treat linebreaks wrongly, so I
need to track that down.
https://github.com/neo4j/gremlin-plugin/blob/master/src/test/java/org/neo4j/server/plugin/gremlin/GremlinPluginFunctionalTest.java#L205
is failing, so I have a test for it :)

Re: [Neo4j] Neo4j server - Gremlin plugin - line break in script
Guillaume,
update -
https://github.com/neo4j/gremlin-plugin/blob/master/src/test/java/org/neo4j/server/plugin/gremlin/GremlinPluginFunctionalTest.java#L205
shows you that you need to escape the newline if you are executing
your test from Java, since one String parsing in your client code is
done before hitting the wire.
Is that the case?

Re: [Neo4j] Neo4j server - Gremlin plugin - line break in script
Guillaume,
I checked this out with people in the know. Actually, unescaped
newline in the middle of a token like your string is not allowed in
JSON, much like in java.
{script:2\n4,
hi:hej}
in the Chrome plugin is working, while
{script:2
4,
hi:hej}
is illegal JSON and will throw the parsing error. This is unfortunate
for the readability of a script, but apparently there is no good way
around it. So, the client library needs to convert linebreaks into \n
if that is interesting. Do others have input on this?

Guillaume, Are you sending it via the rest plugin? In docs.neo4j.org the sample graph example is using multiple lines, separated by semicolon. /peter Sent from my phone.

Re: [Neo4j] Neo4j server - Gremlin plugin - line break in script
Hi Peter,
Thanks for your answer. I knew that it was possible to put semi colons for
line break ;-)
To be more precise, I have the following script that was given kindly given
by Marko on another thread.
m = [:]
g.idx('id')[[object_type:'A']].transform{
if(it.out('USES'){it.object_type.equals('B')}.count() 1)
count = 1
else
count 1
}.groupCount(m) -1
m
I know it is possible to do the same following in one line (see below)
however I would like, for more readability to be able to submit it to the
REST gremlin plugin with multiple lines.
m = [:]
;g.idx('id')[[object_type:'A']].transform{if(it.out('USES'){it.object_type.equals('B')}.count()
1) count = 1 else count 1}.groupCount(m) -1 ; m
Guillaume in holiday tonight ;-)

Mmh,
ok, I get the thought. Will see how we could do that. How would you
like to submit this? JSON with \n instead of ;? Wanna write a test
for this.
Now back to parental leave and the catastrophe in Norway.
