Overview

CLI dispatches the ‘charming` executable’s subcommands to the appropriate generators or database commands. Subcommands:

  • ‘charming new NAME [–database sqlite3] [–force]` — scaffolds a new app

  • ‘charming generate TYPE NAME [args]` — runs a sub-generator (controller, model, screen, view, component)

  • ‘charming db:COMMAND` — runs a database command (db:create, db:migrate, db:rollback, db:drop, db:seed, db:install)

Generator errors are caught and printed to stderr; the process exits with status 1.
