I'm testing "b" for the first time in preparation for our Virtual User Group next week (Command Line Tools for BackdropCMS).
It seems to be working on a high level. I was able to download a copy of Backdrop with b.
However, I'm not sure how to use it with Lando. Any commands that require access to the database seem to generate "The required bootstrap level is not ready" errors.
I assume this is because I am not using "b" from with Lando and it doesn't know how to access to the Lando based database container. But, I could be wrong.
Here a sample message I get:
[-] Backdrop has not yet been installed. [-] 'Debug' mode enabled. [✘] The required bootstrap level for 'enable' is not ready.
For those who are not aware of "b", it is a command line tool similar to drush that has been written specifically for BackdropCMS. https://backdropcms.org/project/b
