fileimport-util 1.0

A package that assist with imports via drag and dropping of files so end users can run scripts with ease

Script that contains utility definitions common to most import scripts

Author: Alok M Date: 11/2015 Packaged by: Devin Akerley Date: 06/2024

This script contains some common function definitions that are needed by most python file import scripts. The goal of this script is to reduce the amount of coding required to generate a new file import script.

The anticipated usage is as follows:

1. include a line at the top of a specific script as follows:

   from fileimport_util import *

2. Define specific functions to read an instrument file and write a corresponding clims file.

   def read_file(filename): ...

   def write_file(filename): ...

In both function definitions, the "filename" corresponds to the fully specified filename that the user has selected. If the user selects multiple files, these functions will be called once for each file. In these, if something goes wrong, the function should raise an exception; any data that needs to be communicated between these should be managed through global variables. Some commonly used filename parsing functions are imported:

3. Call the main function to kick off the processing

   transform(read_file, write_file)

What you get from this file: - pre-imports of commonly used python modules - pre-imports of specific useful components of modules: - pprint() - OrderedDict() - dirname() Example: dirname("a/b/c/a.csv") => "a/b/c" - basename() Example: basename("a/b/c/a.csv") => "a.csv" - splitext() Example: file_part, extension = splitext("a/b/c/a.csv") => ("a/b/c/a", ".csv") - get_input_filenames: provides support to prompt user for filenames; - main(): supports drag/drop of files onto script; if none are provided, then prompts user; then alternates between calling read_file and write_file to process each. - Logger (LOG), useful for logging errors and warnings.
