Dynamically change the kernel startup parameters #12

Closed andrus closed 4 months ago

andrus commented 6 months ago

Maybe there's a more dynamic way to pass the JVM startup arguments to the Java kernel than including them in kernel.json. Would be great it those can be set as environment vars, or in some $HOME/.jupyterc file, etc. I suppose we'll need a shell script to start java in this case, which will make it OS-dependent (or just use the main JVM to start another JVM?)

@m-dzianishchyts , @stariy95 I see there was a PR that went in for this. Let's make sure we mention the new var in README.md docs

@andrus Yep, PR #18 added Python launcher that uses JJ_JVM_OPTS to pass additional args to the Java process. Will add notes to the docs about it.

Close this for now. If we'll need something other than env var to control startup parameters we could open another issue.
