scottbrian-utils 1.2.0

Print header/trailer utilities

Intro

This is a collection of generally useful functions for use with any application.

1. The diag_msg function allows you to print a message with the time and caller sequence added for you.

2. The FileCatalog item allows you to map file names to their paths.

3. The @time_box decorator allows you to print start, stop, and execution times.

4. The print_flower_box_msg function allows you to print text in a flower box (i.e., surrounded by asterisks).

With diag_msg you can print messages with the time and caller info added automatically.

Example:

print a diagnostic message (<input> appears as the module name when run from the console)

>>> from scottbrian_utils.diag_msg import diag_msg
>>> diag_msg('this is a diagnostic message')
16:20:05.909260 <input>:1 this is a diagnostic message

With FileCatalog, you can code your application with file names and retrieve their paths at run time from a catalog. This allows you to use different catalogs for the same set of files, such as one catalog for production and another for testing. Here’s as example:

>>> from scottbrian_utils.file_catalog import FileCatalog
>>> prod_cat = FileCatalog({'file1': Path('/prod_files/file1.csv')})
>>> print(prod_cat.get_path('file1'))
/prod_files/file1.csv

>>> test_cat = FileCatalog({'file1': Path('/test_files/test_file1.csv')})
>>> print(test_cat.get_path('file1'))
/test_files/test_file1.csv

With @time_box, you can decorate a function to be sandwiched between start time and end time messages like this:

>>> from scottbrian_utils.time_hdr import time_box

>>> @time_box
... def func2() -> None:
...      print('2 * 3 =', 2*3)

>>> func2()
<BLANKLINE>
**********************************************
* Starting func2 on Mon Jun 29 2020 18:22:50 *
**********************************************
2 * 3 = 6
<BLANKLINE>
********************************************
* Ending func2 on Mon Jun 29 2020 18:22:51 *
* Elapsed time: 0:00:00.001204             *
