- Extract site-specific logic from bot/random.go into dedicated provider structs - Create providers/ package with LessWrongRuProvider, SlateProvider, AstralProvider, LessWrongProvider - Implement common PostProvider interface for consistency across all sources - Add ProviderFactory for creating providers and managing markdown converters - Build adapter layer to bridge existing bot interfaces with new provider interfaces - Eliminate code duplication by removing ~250 lines of repeated logic - Improve maintainability and testability while preserving all existing functionality 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…hnical debt Major improvements across 6 key areas: 1. **Fix Memory Storage Concurrency Bug** - Add sync.RWMutex protection to prevent race conditions in concurrent map access - Critical production stability improvement 2. **Decompose MessageHandler Method** - Split 84-line monolithic method into focused command handlers - Extract handleCallbackQuery, handleMessage, handleTopCommand, handleRandomCommand, etc. - Improve testability and separation of concerns 3. **Consolidate Top Posts Logic** - Extract common getUserSource() helper to eliminate code duplication - Standardize constants (TopPostsLimit=10, TopPostsWeeklyDays=7) - Update test data to match new consistent limits 4. **Standardize Error Handling** - Create centralized handleCommandError() function - Consistent logging patterns and user messaging across all commands - Better debugging and uniform user experience 5. **Extract Markdown Processing Logic** - Create dedicated formatter/ package with MarkdownFormatter - Move "stupid hotfixes" into organized, testable functions - Eliminate hardcoded PostMaxLength=500, improve reusability 6. **Consolidate Configuration Constants** - Move scattered hardcoded values to config/ package - Centralize DefaultPostLimit, TopPostsLimit, PostMaxLength, etc. - Single source of truth for all application constants Results: ~100 lines reduced, better architecture, eliminated technical debt, all tests passing, no breaking changes to functionality. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…back **Problem**: Bot crashed with "can't parse entities" error when processing posts containing unmatched markdown characters like "_\[Epistemic status..." from Slate Star Codex content. **Root Cause**: Markdown formatter generated invalid Telegram markdown with: - Unmatched underscores breaking emphasis parsing - Incomplete escape sequences (\[ without \]) - Trailing backslashes and other problematic characters **Solution**: 1. **Enhanced Markdown Formatter** (formatter/markdown.go): - Add fixTelegramMarkdown() with specialized Telegram compatibility fixes - fixUnmatchedUnderscores() removes odd underscores to prevent emphasis errors - fixUnmatchedBrackets() cleans up incomplete escape sequences - fixUnmatchedAsterisks() handles single/double asterisk mismatches - cleanLineEnding() removes problematic trailing characters 2. **Robust Message Sending** (bot/bot.go): - Add validateMarkdown() to detect parsing issues before sending - Automatic fallback to plain text when markdown validation fails - Retry mechanism: if Telegram rejects markdown, resend as plain text - Enhanced error logging for better debugging 3. **Comprehensive Testing** (formatter/markdown_test.go): - Unit tests covering all problematic markdown patterns - Verification that the exact error case is handled correctly - Ensures valid markdown formatting is preserved **Result**: No more message failures - graceful degradation to plain text when markdown is invalid, ensuring reliable content delivery. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…and fallback" This reverts commit 59172df.
**Problem**: Bot crashed with "can't parse entities" error when processing Slate Star Codex content containing patterns like "_\[Epistemic status..." **Root Cause**: HTML-to-markdown converter generated escape sequences that break Telegram's strict markdown parsing: - "_\\\\[" and "_\\[" (underscore + escaped brackets) - "\\[" and "\\]" (standalone escaped brackets) - "\\_" (escaped underscores) - Trailing backslashes **Solution**: Targeted pattern replacement approach: 1. **Precise Pattern Fixes** (formatter/markdown.go): - Handle double-escaped sequences from markdown converter - Fix specific problematic patterns without touching valid markdown - Remove trailing backslashes that break parsing - Preserve all legitimate formatting like _italic_ and **bold** 2. **Minimal Fallback** (bot/bot.go): - Only retry as plain text when Telegram explicitly rejects markdown - No pre-validation that could cause false positives - Surgical approach - only intervenes on actual parsing failures 3. **Targeted Testing** (formatter/markdown_test.go): - Test exact problematic patterns from the original error - Verify valid markdown is preserved - Ensure specific HTML content now processes correctly **Result**: Fixes the specific parsing error while preserving all valid markdown formatting. No more false positives or broken emphasis/bold text. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Add helper functions to properly inject mock HTTP client into provider factory - Update all integration tests to use new setup pattern - Ensure mock HTTP client is propagated through provider adapters - Fix variable declarations where needed The tests were failing because after refactoring, HTTP calls now go through providers with their own HTTP client adapters, but the old tests were only mocking the bot's HTTP client. This update ensures the mock client is properly used at the provider level.
- Introduced `interfaces` package to define common `Storage` and `HTTPClient` interfaces. - Updated bot and provider implementations to utilize these interfaces, enhancing modularity. - Refactored integration tests to ensure compatibility with the new provider architecture. - Replaced hardcoded top posts logic with dedicated provider classes for better maintainability. - Added new test data for top posts from Slate Star Codex. This refactor improves the overall structure and testability of the bot, allowing for easier future enhancements.
- Added `.claude/settings.local.json` to `.gitignore` to prevent local settings from being tracked. - Updated `.golangci.yml` to enhance linter configurations, including exclusions for generated files and specific directories. - Removed unused `settings.local.json` file from `.claude` directory. - Deleted `utils.go` file as it contained no longer needed utility functions. - Refactored `adapters.go` to replace deprecated `ioutil.ReadAll` with `io.ReadAll`. - Modified `top_lesswrong_ru.go` to remove context parameter from `scrapePosts` method and improved logging for caching errors. These changes streamline the codebase and improve linting practices.
- Updated GitHub Actions workflows to run on Ubuntu 24.04 and upgraded `setup-go` and `golangci-lint-action` to their latest versions. - Refactored `adapters.go` to replace deprecated `ioutil.ReadAll` with `io.ReadAll`, improving compatibility with current Go standards. These changes enhance the CI environment and modernize the codebase.
- Added string trimming to expected and actual results in `TestTopPosts` to ensure whitespace does not affect test outcomes. - Updated mock API responses in `astral_top_posts.md` and `lesswrong_ru_top_posts.md` to reflect more accurate content. - Corrected URLs in `slate_top_posts.md` for consistency. - Modified `top_lesswrong_ru.go` to prevent extra newlines after the last post in the formatted output. These changes improve the reliability of tests and ensure the accuracy of top posts data formatting.
- Replaced the `CreateTopPostsProvider` method with a more generic `CreateProvider` method in the provider factory, streamlining provider creation. - Implemented `GetTopPosts` methods for `AstralProvider`, `LessWrongRuProvider`, and `LessWrongProvider`, allowing each provider to fetch and format top posts independently. - Removed obsolete top posts provider files for Astral and LessWrongRu, consolidating logic into their respective providers. - Updated the `TopPosts` method in the bot to utilize the new provider structure, ensuring consistent data retrieval across sources. These changes improve the modularity and maintainability of the top posts functionality within the bot.
- Updated error logging in `bot.go`, `astral.go`, and `lesswrong.go` to use `[ERROR]` level for better visibility of issues. - Enhanced error handling in `fetchTopPosts` methods to return empty posts on API failures, ensuring fallback mechanisms are triggered. - Refactored `handleResponse` in `lesswrong.go` to check for HTML responses, improving robustness against unexpected API outputs. These changes enhance the reliability and maintainability of the bot's provider interactions.
