From 6e60e5f13d90128c1c9b9af4fce6f89646eb30a6 Mon Sep 17 00:00:00 2001 From: tegwick Date: Sat, 25 Oct 2025 21:35:53 +0200 Subject: [PATCH] feat: enhance empty line preservation and automatic paragraph separation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented sophisticated paragraph handling for the markdown editor: Enhanced HTML-to-Markdown Conversion: - Replaced simple tag stripping with proper structural parsing - Preserves formatting for headers, emphasis, code, blockquotes - Maintains paragraph separation with proper spacing - Handles nested elements and mixed content correctly Dynamic Section Splitting: - Detects paragraph breaks (double newlines) when editing - Automatically creates separate editable sections for each paragraph - Enables independent editing of logically separate content - Maintains proper section indexing with sub-identifiers Visual Enhancements: - Added green styling for edited sections to distinguish from originals - Subtle borders and backgrounds indicate modified content - Hover effects provide clear feedback on editable areas Technical Improvements: - Enhanced blur handler to detect multiple paragraphs - Smart wrapper creation for single vs. multi-paragraph content - Proper DOM manipulation for section insertion and replacement - Preserves editing state and section relationships Benefits: - Empty lines between paragraphs are preserved accurately - Text separated by empty lines becomes independently editable - Better content organization and editing granularity - Improved user experience with clear visual feedback This resolves the empty line swallowing issue and provides intuitive paragraph-level editing that matches user expectations. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- markitect/document_manager.py | 99 +++++++++++++++++++++++++++++++---- 1 file changed, 89 insertions(+), 10 deletions(-) diff --git a/markitect/document_manager.py b/markitect/document_manager.py index 3ce41f57..2e4cfbab 100644 --- a/markitect/document_manager.py +++ b/markitect/document_manager.py @@ -618,6 +618,16 @@ class DocumentManager: background: rgba(0, 122, 204, 0.05);
