From 1a67f1f91232f841895323797213fea5a90e14b8 Mon Sep 17 00:00:00 2001 From: Luis Novo Date: Sun, 19 Oct 2025 15:38:59 -0300 Subject: [PATCH] fix: enhance chat reference links and prevent text overflow (#173) This commit addresses two related issues in the chat interface: 1. **Fix broken reference links (OSS-310)** - Completely rewrote convertReferencesToMarkdownLinks() with greedy pattern matching - Now handles all edge cases: references after commas, nested brackets, bold markdown - Added visual icon indicators (FileText, Lightbulb, FileEdit) for reference types - Implemented proper error handling with toast notifications - Added validation for reference types and ID lengths 2. **Fix long URL/text overflow (#172)** - Added break-words and overflow-wrap classes to chat messages - Long URLs and text now wrap properly within chat bubbles - Applied fix consistently across source chat, notebook chat, and search results **Technical Details:** - Enhanced reference detection algorithm processes from end to start to preserve indices - Context analysis (50 chars before/after) determines original formatting - Icons are 12px, accessible, and themed appropriately - All changes pass linting and build successfully **Files Modified:** - frontend/src/lib/utils/source-references.tsx (core algorithm rewrite) - frontend/src/components/source/ChatPanel.tsx (error handling + text wrapping) - frontend/src/components/search/StreamingResponse.tsx (error handling + text wrapping) - open_notebook/utils/token_utils.py (ruff formatting fix) fixes #172 --- .../components/search/StreamingResponse.tsx | 14 ++- frontend/src/components/source/ChatPanel.tsx | 16 ++- frontend/src/lib/utils/source-references.tsx | 114 +++++++++++++++--- open_notebook/utils/token_utils.py | 1 + 4 files changed, 124 insertions(+), 21 deletions(-) diff --git a/frontend/src/components/search/StreamingResponse.tsx b/frontend/src/components/search/StreamingResponse.tsx index 07e0f27..36e74bb 100644 --- a/frontend/src/components/search/StreamingResponse.tsx +++ b/frontend/src/components/search/StreamingResponse.tsx @@ -9,6 +9,7 @@ import { useState } from 'react' import ReactMarkdown from 'react-markdown' import { convertReferencesToMarkdownLinks, createReferenceLinkComponent } from '@/lib/utils/source-references' import { useModalManager } from '@/lib/hooks/use-modal-manager' +import { toast } from 'sonner' interface StrategyData { reasoning: string @@ -34,7 +35,16 @@ export function StreamingResponse({ const handleReferenceClick = (type: string, id: string) => { const modalType = type === 'source_insight' ?
