* feat: Add table, image, and nested list support to HTML parser
- Add Table, Image, and Form data structures
- Implement table extraction with proper row/column parsing
- Add image extraction with alt text and dimensions
- Implement recursive nested list parsing (ul/ol)
- Support ordered and unordered lists with nesting levels
- Extract list item numbers for ordered lists
- Add HEADING4-6, ORDERED_LIST_ITEM, TABLE, IMAGE element types
This enhancement allows TUT to properly extract and represent
structured content from HTML, enabling better rendering of
data-heavy websites.
* feat: Implement beautiful table and image rendering with box-drawing
- Add Unicode box-drawing characters for table borders (┌─┬─┐, │, etc.)
- Implement table rendering with proper column width calculation
- Add header row styling with heavy borders and bold text
- Support automatic text wrapping within table cells
- Implement image placeholder rendering with bordered boxes
- Display image alt text and dimensions (width × height)
- Enhance list rendering with different bullet styles per nesting level
* Level 0: • (bullet)
* Level 1: ◦ (white bullet)
* Level 2: ▪ (small square)
* Level 3: ▫ (white small square)
- Add ordered list rendering with proper numbering
- Support proper indentation for nested lists
These visual enhancements make TUT significantly more modern and
readable compared to traditional text browsers like w3m.
* feat: Add Vimium-style link hints and vim keybindings infrastructure
- Add LINK_HINTS mode for Vimium-style link navigation
- Implement 'f' key to activate link hints mode
- Add visual mode support (v/V keys)
- Implement marks support (m[a-z] to set, '[a-z] to jump)
- Add tab navigation keys (gt/gT for next/previous tab)
- Add new actions:
* SHOW_LINK_HINTS - activate link hints overlay
* FOLLOW_LINK_HINT - follow link by hint letters
* ENTER_VISUAL_MODE / ENTER_VISUAL_LINE_MODE
* SET_MARK / GOTO_MARK - vim-style position bookmarks
* NEXT_TAB / PREV_TAB - tab navigation
* YANK - copy selected text
This brings modern browser vim plugin functionality (like Vimium)
to the terminal, making link navigation much faster than traditional
tab-through methods.
Major improvements to link handling and navigation:
Features:
- Display links inline with numbered indicators [0], [1], etc.
- Quick navigation: type number + Enter to jump to link
- Fast follow: press 'f' + number to open link directly
- Visual improvements: links shown with underline and highlight
- Remove separate link list at bottom for better readability
Technical changes:
- Add InlineLink structure to track link positions in text
- Implement wrap_text_with_links() for intelligent text wrapping
- Add GOTO_LINK and FOLLOW_LINK_NUM actions
- Implement LINK input mode for 'f' command
- Character-by-character rendering for proper link highlighting
- Update help documentation with new navigation methods
Usage examples:
- 3<Enter> : Jump to link 3
- f5 or 5f : Open link 5 directly
- Tab/Enter : Traditional navigation still works
All comments converted to standard Unix style (English).
Following Unix philosophy and documentation standards:
- Rewrite README.md in man page format (NAME, SYNOPSIS, DESCRIPTION, etc.)
- Remove all Chinese comments from source code
- Keep code clean and self-documenting
- Add PHILOSOPHY section explaining Unix principles
- Include proper EXIT STATUS, ENVIRONMENT, and FILES sections
- Reference related tools in SEE ALSO section
* feat: Add HTTP/HTTPS client module
Implement HTTP client with libcurl for fetching web pages:
- Support for HTTP and HTTPS protocols
- Configurable timeout and user agent
- Automatic redirect following
- SSL certificate verification
- Pimpl pattern for implementation hiding
This module provides the foundation for web page retrieval
in the terminal browser.
* feat: Add HTML parser and content extraction
Implement HTML parser for extracting readable content:
- Parse HTML structure (headings, paragraphs, lists, links)
- Extract and decode HTML entities
- Smart content area detection (article, main, body)
- Relative URL to absolute URL conversion
- Support for both absolute and relative paths
- Filter out scripts, styles, and non-content elements
The parser uses regex-based extraction optimized for
text-heavy websites and documentation.
* feat: Add newspaper-style text rendering engine
Implement text renderer with adaptive layout:
- Adaptive width with maximum 80 characters
- Center-aligned content for comfortable reading
- Smart text wrapping and paragraph spacing
- Color scheme optimized for terminal reading
- Support for headings, paragraphs, lists, and links
- Link indicators with numbering
- Horizontal rules and visual separators
The renderer creates a newspaper-like reading experience
optimized for terminal displays.
* feat: Implement vim-style input handling
Add complete vim-style keyboard navigation:
- Normal mode: hjkl movement, gg/G jump, numeric prefixes
- Command mode: :q, :o URL, :r, :h, :[number]
- Search mode: / for search, n/N for next/previous match
- Link navigation: Tab/Shift-Tab, Enter to follow
- Scroll commands: Ctrl-D/U, Space, b for page up/down
- History navigation: h for back, l for forward
Input handler manages mode transitions and command parsing
with full vim compatibility.
* feat: Implement browser core with TUI interface
Add main browser engine and user interface:
- Page loading with HTTP client integration
- HTML parsing and text rendering pipeline
- History management (back/forward navigation)
- Link selection and following with Tab navigation
- Search functionality with highlighting
- Scrolling with position tracking
- Status bar with mode indicator and progress
- Built-in help page with usage instructions
- Error handling and user feedback
- Support for static HTML websites
The browser provides a complete vim-style terminal
browsing experience optimized for reading text content.
* build: Update build system for terminal browser
Update CMake and add Makefile for the new project:
- Rename project from NBTCA_TUI to TUT
- Update executable name from nbtca_tui to tut
- Add all new source files to build
- Include Makefile for environments without CMake
- Update .gitignore for build artifacts
Both CMake and Make build systems are now supported
for maximum compatibility.
