argv[0]

Stream: lean4

[Jason Gross]

Is there any way to get argv[0] in Lean?

[Marc Huisinga]

@Jason Gross If you asked this question because lean4-cli expects the first argument to be the application name while args does not contain it, I've fixed that in lean4-cli now.

No, it was because I'd like to be able to pick up the executable name from argv[0] for displaying usage messages
