transpo-dir
transpo is a tool to "transpose" directory structure.
Have you ever needed to create a directory structure that looks like a two-dimensional spreadsheet? For example, let's say you have product sales data stored in a directory where the first level is the product name and the second level is the month.
Now you want to convert this to a directory structure where the first level is the month and the second level is the product name.
The tool transpo supports such a change of directory structure.
Installation
By installing the package transpo-dir with pip, an executable transpo will be installed on your system.
pip install transpo-dirIf you get the error ModuleNotFoundError: No module named 'docopt' when running transpo, install the package docopt-ng or docopt.
pip install docopt-ngUsage
transpo [options] <src> -d DEST
Options
-d DEST Destination directory.
-i INDICES, --index-order=INDICES The order of indices for transpose [default: 21].
