Question 1

How do I install lgo on a Mac?

Accepted Answer

lgo does not support macOS natively; you must use Docker or a virtual machine. Follow the Docker Compose instructions in the README to run it in a containerized environment.

Question 2

lgo vs gophernotes: which is better for Go in Jupyter?

Accepted Answer

lgo uses the standard Go compiler for full language support and better performance, but has issues with newer Go versions. Gophernotes uses an interpreter, supports more platforms natively, but lacks some Go features like interfaces and is slower.

Question 3

How to handle memory leaks in lgo?

Accepted Answer

Memory is managed by Go's garbage collector, but be cautious with global variables—shadowing can prevent memory release. Use local variables or explicitly set globals to nil to free memory, as explained in the README's memory management section.

Question 4

Why does my lgo kernel keep dying in Jupyter?

Accepted Answer

This often occurs if your code calls os.Exit or log.Fatal, which terminate the kernel process. Avoid these calls and use context cancellation via _ctx for safe interrupts, as detailed in the troubleshooting section.

Question 5

Can I use lgo with JupyterLab?

Accepted Answer

Yes, lgo works with JupyterLab, but you need to install an extension by running 'jupyter labextension install @yunabe/lgo_extension' to add features like a Go Format button in the toolbar.

Question 6

How to update lgo when I upgrade my Go version?

Accepted Answer

After upgrading Go, run 'lgo install --clean' to reinstall prebuilt packages with the new compiler, as binary formats may change and cause errors like 'multiple roots' or 'old export format'.
