beakerx_kernel_groovy's Issues

Error MissingPropertyException because of inconsistent scoping of local variables through this groovy kernel

I am trying to run this code on groovy kernel and its give a strange error.

import java.util.zip.ZipEntry
import java.util.zip.ZipFile
zipInputFile = new ZipFile(file)
list = entires.toList();
zipInputFile.getInputStream(list.get(0))

This is the exception it is giving. while running the same code works with normal execution of groovy script.

groovy.lang.MissingPropertyException: No such property: file for class: script1622875172283
	at this cell line 3
	at com.twosigma.beakerx.groovy.evaluator.GroovyCodeRunner.runScript(GroovyCodeRunner.java:94)
	at com.twosigma.beakerx.groovy.evaluator.GroovyCodeRunner.call(GroovyCodeRunner.java:59)
	at com.twosigma.beakerx.groovy.evaluator.GroovyCodeRunner.call(GroovyCodeRunner.java:32)

Later I found this is happening because this kernel don't share local variables across the cells. But it still share local variable declared at last line.
So if I write,

import java.util.zip.ZipEntry
import java.util.zip.ZipFile

String file = "C:\\Users\\user\\.gradle\\caches\\modules-2\\files-2.1\\org.apache.bcel\\bcel\\6.5.0\\79b1975ec0c7a6c1a15e19fb3a58cc4041b4aaea\\bcel-6.5.0.jar"
zipInputFile = new ZipFile(file);

in a separate cell 'zipInputFile' will be scoped to next cell.

But when I declare variable mentioning its type. (both ways are valid in groovy)

import java.util.zip.ZipEntry
import java.util.zip.ZipFile

String file = "C:\\Users\\user\\.gradle\\caches\\modules-2\\files-2.1\\org.apache.bcel\\bcel\\6.5.0\\79b1975ec0c7a6c1a15e19fb3a58cc4041b4aaea\\bcel-6.5.0.jar"
ZipFile zipInputFile = new ZipFile(file);

The zipInputFile will not get scoped to the next cell. Why is this inconsistency ?

doc doesn't work

"Shift" + "Tab" display nothing:

Expected result:

TableDisplayLoadingMode.ENDLESS doesn't work

try the code on Groovy:

import java.util.function.Supplier
import java.util.stream.Stream
TableDisplay.setLoadingMode(TableDisplayLoadingMode.ENDLESS)
def generate = Stream.generate(new Supplier<Map<String, Object>>() {
    def random = new Random()
    def index = 0
    @Override
    Map<String, Object> get() {
        return [
            str1: index++,
            str2: random.nextDouble(),
            str3: random.nextFloat()
        ]
    }
    })
new TableDisplay(generate)

It will create table with limited count of rows

Expected result is endless table

%showEnvs command interrupt kernel

look at test/ipynb/groovy/KernelAPITest.ipynb

How is the working directory set in Groovy script?

We have an implementation of a kernel based on this one that incorporates the Micronaut framework (https://github.com/stainlessai/micronaut-jupyter). When we switch kernels from Groovy, however, the working directory changes and I can't figure out why.

Using this kernel from any path in the jupyter context, e.g., $HOME/my/working/dir, the code:

println new File(".").absolutePath

returns

$HOME/my/working/dir

How does this path get passed to the Groovy script code for running the cell?
