Project Plan for Code Enhancements

This document outlines the steps to enhance the project with several improvements across different areas of the codebase.

1. Internationalization (i18n) for FizzBuzz

Objective: Update the fizzboop/fizzbuzz.py file to support multiple languages.

Steps:

  • Import the built-in gettext module.
  • Initialize the translation system by adding: 
    import gettext
t = gettext.translation('fizzbuzz', localedir='locales', fallback=True)
_ = t.gettext
  • Wrap all user-facing string literals (e.g., in print statements: "Fizz", "Buzz", "FizzBuzz") with the translation function _(). For example: 
    print(_("Fizz"))
  • Create a locales directory in the project root with subdirectories for each target locale (e.g., en, es, fr).
  • Generate and manage a template .po file for translators, and provide instructions for compiling these into .mo files for runtime usage.

2. Redis Caching for FizzBuzz

Objective: Enhance performance by caching results of the FizzBuzz computation.

Steps:

  • Verify if Redis is already imported; if not, add: 
    import redis
redis_client = redis.Redis(host='localhost', port=6379, db=0)
  • Within the fizzbuzz function, generate a unique cache key based on the input n.
  • Before processing, check if a cached output exists:
    • If a cached result is found, retrieve and print it.
    • If not, compute the fizzbuzz output, cache the result using setex() with an expiration time (e.g., 3600 seconds), and then print it.
  • Add logging to capture any caching errors.

3. Enhanced Error Handling

Objective: Replace bare except: clauses with explicit exception handling for improved error clarity.

Steps:

  • Search for all instances of bare except: clauses across the codebase.
  • Analyze each usage to determine the specific exception(s) that should be caught (e.g., ValueError, IOError).
  • Update the code to explicitly catch these exceptions. For instance, replace: 
    except:
    with: 
    except ValueError:
    or: 
    except (IOError, OSError):
  • Include inline comments explaining the chosen exception types.
  • Validate changes with tests to ensure proper error reporting.

4. Update Parser Usage

Objective: Replace the deprecated tokenizer from otherParser with bobFinkling from yetAnotherParser.

Steps:

  • Locate all import statements and usages of the old tokenizer in the codebase (e.g., within example/bob.py).
  • Change the import statement from: 
    import tokenize, parse, atom from otherParser
    to: 
    from yetAnotherParser import bobFinkling
  • Update all usages of the old tokenizer to use bobFinkling instead.
  • Perform tests with sample inputs to confirm the new parser functionality is working as expected.

5. Testing

& Documentation

Objective: Ensure that all enhancements function correctly and update the project documentation accordingly.

Steps:

  • Execute unit tests and manual tests covering:
    • Internationalization changes in fizzboop/fizzbuzz.py.
    • Redis caching functionality.
    • Revised error handling modifications.
    • Parser usage updates.
  • Update README.md or other relevant documentation to include:
    • Instructions for adding new locales and compiling translation files.
    • An explanation of the caching strategy and how to troubleshoot it.
    • Details about the parser changes with bobFinkling integration.
