From b0de32d083862c83c4f28ff9a712356838fd1794 Mon Sep 17 00:00:00 2001 From: tegwick Date: Fri, 3 Oct 2025 11:23:32 +0200 Subject: [PATCH] feat: implement comprehensive plugin architecture and extensions system (issue #19) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete plugin system implementation providing extensible architecture for MarkiTect: ๐Ÿ—๏ธ **Core Plugin Architecture**: - BasePlugin abstract class with lifecycle management (initialize/cleanup) - Specialized plugin types: ProcessorPlugin, FormatterPlugin, ValidatorPlugin, ExporterPlugin, CommandPlugin - PluginMetadata system with version, dependencies, and type information - Plugin initialization and configuration validation ๐Ÿ” **Plugin Discovery & Management**: - PluginManager with automatic discovery from built-in modules and directories - PluginRegistry for centralized plugin registration and lifecycle management - Support for plugin loading, unloading, and reloading with configuration - Plugin discovery from multiple sources (built-in, directories, packages) ๐Ÿ› ๏ธ **CLI Integration**: - markitect plugin-list: List all available plugins with metadata - markitect plugin-load: Load plugins with optional configuration - markitect plugin-unload: Unload plugins and cleanup resources - markitect plugin-info: Show detailed plugin information - markitect plugin-discover: Discover and refresh plugin catalog ๐Ÿ“ฆ **Built-in Plugins**: - JSON/YAML/Table formatters for output formatting - Markdown/Text processors for content processing - Auto-registered via @register_plugin decorator - Comprehensive configuration options ๐Ÿ”ง **Developer Experience**: - @register_plugin decorator for easy plugin registration - Plugin configuration validation and error handling - Comprehensive API documentation with examples - Plugin development guide and best practices ๐Ÿ“‹ **Example Plugins**: - Advanced text processor with case conversion and pattern replacement - XML/CSV formatters demonstrating custom output formats - Complete examples showing plugin development patterns ๐Ÿงช **Test Coverage**: - 59 comprehensive tests covering all plugin functionality - Tests for plugin lifecycle, registration, discovery, and CLI integration - Error handling and edge case coverage - Built-in plugin validation Technical Implementation: - Plugin types: processor, formatter, validator, exporter, generator, importer, transformer, extension, backend, command - Configuration-driven plugin management with YAML/JSON support - Graceful error handling and plugin isolation - Plugin dependency validation and compatibility checking ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- examples/plugins/example_formatter.py | 285 +++++++ examples/plugins/example_processor.py | 175 +++++ markitect/cli.py | 240 ++++++ markitect/plugins/README.md | 424 ++++++++++ markitect/plugins/__init__.py | 34 + markitect/plugins/base.py | 272 +++++++ markitect/plugins/builtin/__init__.py | 5 + markitect/plugins/builtin/formatters.py | 154 ++++ markitect/plugins/builtin/processors.py | 136 ++++ markitect/plugins/decorators.py | 31 + markitect/plugins/manager.py | 342 +++++++++ markitect/plugins/registry.py | 207 +++++ tests/test_issue_19_plugin_architecture.py | 855 +++++++++++++++++++++ 13 files changed, 3160 insertions(+) create mode 100644 examples/plugins/example_formatter.py create mode 100644 examples/plugins/example_processor.py create mode 100644 markitect/plugins/README.md create mode 100644 markitect/plugins/__init__.py create mode 100644 markitect/plugins/base.py create mode 100644 markitect/plugins/builtin/__init__.py create mode 100644 markitect/plugins/builtin/formatters.py create mode 100644 markitect/plugins/builtin/processors.py create mode 100644 markitect/plugins/decorators.py create mode 100644 markitect/plugins/manager.py create mode 100644 markitect/plugins/registry.py create mode 100644 tests/test_issue_19_plugin_architecture.py diff --git a/examples/plugins/example_formatter.py b/examples/plugins/example_formatter.py new file mode 100644 index 00000000..5932269a --- /dev/null +++ b/examples/plugins/example_formatter.py @@ -0,0 +1,285 @@ +""" +Example formatter plugin for MarkiTect. + +This demonstrates how to create a custom formatter plugin. +""" + +import xml.etree.ElementTree as ET +from datetime import datetime +from typing import Any, Dict, List, Union + +from markitect.plugins.base import FormatterPlugin, PluginMetadata, PluginType +from markitect.plugins.decorators import register_plugin + + +@register_plugin("xml_formatter") +class XmlFormatter(FormatterPlugin): + """ + XML formatter plugin that converts data structures to XML format. + + Supports formatting of dictionaries, lists, and primitive types into + well-formed XML with customizable root element and formatting options. + """ + + @property + def metadata(self) -> PluginMetadata: + return PluginMetadata( + name="xml_formatter", + version="1.0.0", + description="Format output as XML", + author="MarkiTect Team", + plugin_type=PluginType.FORMATTER + ) + + def format(self, data: Any, **kwargs) -> str: + """ + Format data as XML. + + Args: + data: Data to format + **kwargs: Formatting options: + -
