Let jupyter C++ kernel pick up `.rootlogon.C` automatically

ROOT

In current last version of ROOT, jupyter C++ kernel does not pick up ~/.rootlogon.C automatically. Users have to load it manually in the first block:

gROOT->LoadMacro("/home/chn/.rootlogon.C");

Are there any other files that are automatically picked up by ROOT C++ Interpreter? I want to specify additional include path and libraries to the kernel.

I know this issue has been discussed several years ago (here), where it says:

The reason is that the ROOT C++ kernel is actually implemented in Python, which takes what you write in the cell and forwards it as a string to the ROOT interpreter for execution.

Is there any specific reason that making the C++ kernel not loading .rootlogon.C? I want to first hack the source code to make it work on my machine.

ROOT Version: 6.34.0
Platform: Linux
Compiler: GCC 13

Hi,

Apologies if things did not work out of the box for you: it won’t be much of a issue to implement the automatic reading of the rootlogon. Could you please file an issue on our tracker?

Cheers,
Danilo
