Command-line options
Start the playground with no arguments and it opens a fresh, automatically named temporary project so you can begin straight away:
rdbms-playgroundTo open an existing project, give its path:
rdbms-playground path/to/projectOptions
Section titled “Options”| Option | Effect |
|---|---|
--resume | Reopen the most recently used project. Errors if there is none; cannot be combined with a project path. |
--data-dir <PATH> | Use PATH as the data root instead of the OS-standard location for this run. |
--mode <simple|advanced> | Start in this input mode, overriding the project’s stored mode (precedence: --mode > stored > simple). |
--theme <light|dark> | Force a theme instead of auto-detecting from the terminal. |
--no-undo | Disable the undo machinery for this run — no snapshot is taken before each change (see Undo, redo & history). |
--demo | Turn on demonstration mode — a teaching aid that briefly shows an on-screen badge for keys that otherwise leave no visible mark (Tab, Enter, the arrows, and the like). Useful for screencasts and for demonstrating the playground to a class. Off by default. |
--log-file <PATH> | Write diagnostic logging to PATH. |
-h, --help | Print the usage banner and exit. |
