Project: QGIS
Version: 3.8
In QGIS 3.8 we moved the existing "double click column header" to fill values down functionality to a new "Auto fill" button in the Processing Batch dialog, making this feature much more user-discoverable (we suspect many users had no idea this handy shortcut even existed!). In addition, we've added TONS of new functionality to easily auto-populate the batch table. These include:
- File or layer parameters can now be batch populated by searching for files in a directory with a matching filename pattern (including recursive searches!). Ever needed to auto convert 100s of Shapefiles from a set of folders? Now it's easy to do!
- An option to add calculated values from a QGIS expression, allowing complex range-based values to be added to the dialog (e.g. values from 100-1000, increasing by 50)
- A "Calculate by Expression" option allows for updating existing batch table cells using the results of a QGIS expression. These expressions can freely utilise other parameter values from the input batch rows, making it easy to craft the exact output file name you desire based on the other columns values in a batch row.
