eseas is a Python package that acts as a wrapper for the jwsacruncher Java package. This tool allows users to process Demetra workspace XML files, create batch files, execute them, and collect the desired outputs into individual Excel files.

You can install the eseas package via pip:

pip install eseas

Alternatively, you can install it from a local wheel file:

pip install ./eseas-0.1.0-py3-none-any.whl

The jwsacruncher tool is required for this package to function. You can download the latest release of jwsacruncher from the jdemetra releases.

# Download jwsacruncher
cd jdemetra/jswacruncher

After downloading jwsacruncher, you need to specify its location when using the Options function from the eseas package.

Here's an example of how to use the eseas package:

from eseas import Seasonal, Options
import time

def main():
    # Specify the path to the jwsacruncher bin directory
    java_folder = r'../jwsacruncher-2.2.4/bin'
    demetra_source_folder = r"./demetra_source_folder"
    local_folder = r"./test_out"

    options = Options(
        demetra_source_folder,
        java_folder,
        local_folder,
        result_file_names=("sa", "s_f", "cal"), # *1 
         
        workspace_mode=True,
        file_name_explanation=True,
    )
    # Note (1)
    # result_file_names see full list of result types from Demetra Components below

    seas = Seasonal(options)
    
    seas.part1()
    time.sleep(10)
    seas.part2()

if __name__ == "__main__":
    main()
