EasyCsv v0.3.0

[0.3.0] - 2026-08-08

Added

• AI assistant: natural-language requests are converted into xan command pipelines with a RAG-based system prompt that injects only the command docs relevant to the current query.
  • New call_ai Tauri command (DeepSeek / GLM / Qwen), persisted AI provider/model/API key config.
  • AI panel with chat UI, history, and one-click insertion of generated commands into the pipeline.
  • Numbered multi-step AI responses (parsed both inside and outside code blocks), batch-adding multiple commands in a single update.
  • Thumbs up/down feedback with toggle support, intent clarification dialog for ambiguous queries, conversation history context for multi-turn responses.
  • SQLite-based AI memory persistence (conversations, feedback, correction rules); learning-data management in settings.
  • RAG upgrade: synonym expansion, fuzzy matching, correction rule weighting.
  • GLM provider added; token usage tracking (prompt/completion/total) for all providers.
  • Multi-line numbered JSON parser for AI command responses.
• Chart command: chart with line, scatter, bar, histogram, pie, wordcloud and heatmap chart types.
  • Multiple series display via category parameter with custom legend toggle (hidden series shown in gray).
  • Dynamic form fields based on the selected chart type.
  • SVG export, dark mode, hover tooltips, and click-to-toggle for heatmap cells.
  • Chart command documentation (EN + ZH) added.
• Encrypted per-provider API key storage: config migrated from JSON to SQLite (config.db); AES-256-GCM encryption with machine-derived key; new Tauri commands save_api_key / load_api_key / delete_api_key / has_api_key.
• Data lineage visualization overhaul: manual positioning for precise column layout, fullscreen mode (Esc to exit), MiniMap/Controls/Background, Graph/Timeline view toggle, column-level source tracking, auto-track on every execution.
• Pipeline version control, conditional branches, and data lineage.
• LogPanel: maximize/restore toggle and tooltips on action buttons.
• ContextMenu: Neg action.
• Frontend unit tests: vitest infrastructure with 155 tests covering command parameters, Tauri invoke call patterns, batch filter and batch convert logic.
• New app icon.

Changed

• App architecture: split App.tsx (1133 lines) into 6 focused hooks (useTabs, usePipelineState, useAppSettings, useToast, useLogs, useUIState); global keyboard shortcuts moved to App level.
• Performance: removed duplicate getLayoutedElements call, shallow-equality pipeline comparison, 150ms-debounced CommandList search, React.memo on 5 heavy components, Map-based O(1) command lookup.
• AI prompt rules: use search for equality filters, to for non-CSV exports, cat with mode=rows + union + glob for directory merges; deduplicated rules; enforced as clause for new columns in map/groupby/agg.
• AI panel input: auto-resizing textarea (1–4 lines), send shortcut changed from Enter to Ctrl+Enter, send button moved inside textarea.
• Version history: auto-save version on pipeline execution; loadVersions(tabId) called on init and tab switch to fix persistence on refresh; removed the separate "history" tab.
• Panels: LogPanel moved to bottom-right with per-message delete; panel widths made responsive with min() CSS; conditional branches removed.
• Docs: markdown docs moved from public/ to src/docs/ for Vite compatibility and inlined at build time (eliminates fetch).
• Dependencies: @tauri-apps/api upgraded to 2.11.1; recharts@^2.15.3 added.

Fixed

• Table-node scrollbar drag/wheel inside React Flow canvas.
• Version history not loading after refresh.
• get_db() panics replaced with proper error propagation (no more crashes when DB is unavailable).
• Search/filter pattern escaping when pattern starts with - (xan flag parsing).
• Input typing bug and ScrollArea height in SearchFilterForms.
• HelpDialog search input losing focus on keystroke.
• Context menu enabled on panels.
• VersionControlPanel cross-contamination of shared newTag state; delete confirmation added.
• Keyboard shortcut behavior; empty-state and recent-files cleanup.
• Dialog accessibility: role="dialog", focus trap, backdrop click-to-close, Escape handling on all 5 dialogs.
• No-drag class consolidation on draggable dialogs.
• Manual command additions no longer auto-create edges (only AI-inserted commands do).

Removed

• HuggingFace provider support.
• PersistentNotification panel and simplified notification system.
• Redundant undo/redo logic (consolidated into usePipelineState).
• Dead code: save_history/load_history, history_limit, HistoricalPipeline interface and related state.

Docs

• README overhaul: features, testing, keyboard shortcuts, AI providers/models, docs locations, and xan.exe embedding note.
• Refresh help docs and light/dark screenshots.
• AI docs index and merged USAGE.md combining the 58 per-command docs.
