Build with: cmake --build build_v2
Run: ./build_v2/tut2 [URL]
Add full support for POST method form submissions alongside existing GET support.
Changes:
- Add HttpClient::post() method with configurable Content-Type
- Implement URL encoding for form data (RFC 3986 compliant)
- Update Browser::submit_form() to detect and handle both GET and POST methods
- Add proper form data encoding with special character handling
- Include Content-Type header for POST requests
Features:
- Automatic method detection from form's method attribute
- URL-encoded form data (application/x-www-form-urlencoded)
- Proper encoding of special characters (spaces, &, =, etc.)
- Status messages for form submission feedback
- History tracking for POST responses
Testing:
- Add test_post_form.html with GET, POST, and special character test cases
- Uses httpbin.org endpoints for validation
Resolves TODO at browser.cpp:238 - POST handling is now fully implemented.
Major improvements:
- Add proper DOM tree structure (dom_tree.cpp/h) with hierarchical node representation
- Refactor HTML parser to use DOM tree instead of flat ContentElement structure
- Enhance text renderer with improved inline content handling and UTF-8 support
- Improve browser interactive element tracking with byte-accurate positioning
- Add comprehensive HTML entity decoding (80+ named entities + numeric)
- Enhance form handling with better field tracking and submission
Code quality improvements:
- Fix all compiler warnings (unused parameters/variables)
- Clean build with zero warnings
- Better separation of concerns between parsing and rendering
Testing:
- Add test_table.html for table rendering verification
This change enables better handling of complex HTML structures while
maintaining the Unix philosophy of simplicity and focus.
* 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.
* docs: Complete project transformation to terminal browser
Transform project from ICS calendar viewer to terminal browser:
- Rewrite main.cpp for browser launch with URL argument support
- Complete README rewrite with:
- New project description and features
- Comprehensive keyboard shortcuts documentation
- Installation guide for multiple platforms
- Usage examples and best practices
- JavaScript/SPA limitations explanation
- Architecture overview
- Add help command line option
- Update version to 1.0.0
The project is now TUT (Terminal User Interface Browser),
a vim-style terminal web browser optimized for reading.
