How do I get the root directory in one command?

Question

In Git, I can get the root directory from any subdirectory like this:

git rev-parse --show-toplevel

From here: Is there a way to get the git root directory in one command?

Unfortunately this same command does not work in a repo cloned with Sapling, it just returns the current directory.

Could someone tell me how to do this with Sapling, ideally with a similarly simple one-liner?

Answer 1

In Sapling, it is simply sl root.

Note that Sapling has in-product help for finding the analogue to a Git command via sl git. In this case, sl git -- rev-parse --show-toplevel returns sl root, as desired.
