You mean, the Scala interpreter takes a String argument being the script
to execute ? Doesn't the interpreter have a method taking a Reader,
which is the script to execute ?

If there is no reader, yes.

The placement of the script is independent of how the script is actually
executed.

Sling calls the eval(Reader, ScriptContext) method with the reader
providing access to the script source. If you have to call the Scala
interpreter with a String being the script, you will have to read the
content of the Reader into a String (probaly reading from the Reder into
a StringBuffer until EOF and at the end using StringBuffer.toString() to
get the script) and call the interpreter then.
Hope this helps.

Cool. Thanks. Aparently Bertrand has fixed the google codes project.
Still having the JIRA issue is of course required to move any google
code over to the Sling code base.

Will do. Thanks.

Hi Felix,
I've created a jira issue and attached the code as scala.tar.gz till I'm
able to commit to the google project.
Please have a look at it.

Hi,
The attached pom looks like the Rhino/Javascript pom, which certainly
does not load/include the Scala interpreter ...
The interpreter, ready-to-run, does not necessairily show in the web
console. Rather it is the fact, that the interpreter is registered by
the ScriptManager.
I suggest you start committing what you have to the google code project
such that we could be of better help.
Regards
Felix

Hi,
I think the reason is because the scala library which contains the
interpreter is not correctly loading for the script to run.
This is because in the launchpad I don't see the scala.tools.nsc library
loaded.
I can only see the following,
"imported Packagesjavax.script,version=0.0.0 from System Bundle (0)
org.apache.sling.scripting.api,version=2.0.0.incubator-SNAPSHOT from
org.apache.sling.scripting.api (3)"
I guess my maven configuration is not correct. What is the correct way to
add a dependancy to load in sling.
The pom.xml I created is as follows, Apart from this I added the path to the
source folder in the pom.xml file found in sling main directory. please
point out any error I've done.
