4D applications can vary in complexity, but there may be situations where certain operations need to be run in a quick and lightweight manner. The introduction of tool4d in 4D v20 handles this use case by opening the 4D structure (.4DB and .4DProject) to execute 4D code entirely via command prompt or terminal. Some of these cases can include exporting table data, running print jobs, fetching database settings, or verifying data. This tech note will cover how to get started with tool4d and demoing the listed use cases.
