Parse actor data from delimited string format

[Copilot]

Parse actor names from the string actor:Daractor:Darliewithrowliewithrowactor:Darliewithrowactor:Darliewithrow using "actor:" as delimiter, intelligently filtering out corrupted and fragmented names.

Changes

• actor_parser.py: Parser that splits on "actor:" delimiter, filters corrupted names with internal repetitions, removes fragment prefixes, deduplicates while preserving order, supports file input
• test_actor_parser.py: 7 test cases covering parsing logic, duplicates, edge cases, corruption detection
• actor_data.txt: Sample input data
• README.md: Usage documentation
• .gitignore: Standard Python exclusions

Usage

from actor_parser import parse_actors

data = "actor:Daractor:Darliewithrowliewithrowactor:Darliewithrowactor:Darliewithrow"
actors = parse_actors(data)
# Returns: ['Darliewithrow']

python3 actor_parser.py                  # Uses default data
python3 actor_parser.py actor_data.txt   # Reads from file

Implementation

The parser uses a two-pass filtering algorithm:

1. First pass: Identifies corrupted names with internal repetitions (e.g., "Darliewithrowliewithrow")
2. Second pass: Filters out fragment names that are prefixes of longer valid names (e.g., "Dar")

This ensures only valid, complete actor names are extracted from the input.

Original prompt

Pull Request Overview

This PR introduces an actor data parser that extracts and deduplicates actor names from a specially formatted string. The parser splits input on the actor: delimiter and maintains unique actors in order of appearance.

Key Changes:

• Implements a string parser for actor data format actor:<name>actor:<name>...
• Adds comprehensive test coverage for various parsing scenarios
• Provides both CLI and programmatic interfaces for the parser

The Set type is imported but never used in this module. Consider removing it to keep imports clean.

actor:Darliewithrow

Fixed in commit 8859afd. The parser now correctly extracts only "Darliewithrow" from the input string by filtering out corrupted duplicates and fragments.
