A lightweight, terminal-based text editor written in C, inspired by the original Kilo tutorial. This project provides essential text editing capabilities with syntax highlighting, all in a compact and understandable codebase.

C-code is a minimal text editor that operates entirely in raw terminal mode, offering a distraction-free editing experience similar to nano or vim's insert mode. Built with simplicity and educational value in mind, the entire editor is contained in a single ~1500 line C file.

• Full text editing capabilities: Insert, delete, and modify text with ease
• Line operations: Create, delete, and navigate between lines
• Cursor navigation: Arrow keys, Home/End for line navigation, Page Up/Down for scrolling
• Smart deletion: Backspace and Delete key support
• Undo/Redo: Full undo/redo support with up to 1000 levels (Ctrl-Z/Ctrl-Y)
• Copy/Cut/Paste: Line-based clipboard operations (Ctrl-C/Ctrl-X/Ctrl-P)
• Auto-Indentation: Automatic indentation matching with brace-aware smart indent (Ctrl-I to toggle)

• Open existing files: Launch with ./code.exe filename
• Save functionality: Ctrl-S to save changes
• Save As: Prompted automatically for new files
• Unsaved changes protection: Warning before quitting with unsaved work
• Dirty flag tracking: Visual indicator showing when file has been modified

• C/C++ support: Built-in syntax highlighting for C and C++ files
• Keyword highlighting: Two categories of keywords (types and control structures)
• String literals: Highlighted with escape sequence support
• Numbers: Automatic detection and highlighting
• Comments: Both single-line (//) and multi-line (/* */) comment support
• Auto-detection: File extension-based syntax selection

• Text search: Ctrl-F to find text
• Incremental search: Results update as you type
• Navigation: Use arrow keys to jump between matches
• Wrap-around: Search continues from beginning when reaching end
• Visual highlighting: Current match highlighted in blue

• Status bar: Shows filename, line count, file type, and modification status
• Message bar: Context-sensitive messages with 5-second timeout
• Position indicator: Current line and total lines displayed
• Welcome screen: Version information on startup
• Line numbers: Toggleable line numbers in left margin (Ctrl-L to toggle)

• POSIX-compliant system (Linux, macOS, BSD)
• GCC compiler or compatible C compiler
• Terminal with ANSI escape sequence support

# Clone or download the repository
cd c-code

# Compile the editor
make

# This creates the executable: code.exe

Alternatively, compile manually:

gcc code.c -o code.exe -Wall -Wextra -pedantic -std=c99

# Open an existing file
./code.exe myfile.c

# Start with a new file
./code.exe

1. Press Ctrl-F to enter search mode
2. Type your search query
3. Use Arrow Up/Down or Arrow Left/Right to navigate between matches
4. Press Enter or ESC to exit search mode

1. Press Ctrl-Q to quit
2. If you have unsaved changes, you'll be warned
3. Press Ctrl-Q three more times to force quit, or Ctrl-S to save first

The project roadmap includes several planned enhancements:

• Line numbers in left margin
• Undo/Redo functionality
• Copy/Cut/Paste with clipboard
• Auto-indentation
• Column number in status bar

• Search and replace
• Go to line command
• Bracket matching
• Additional syntax highlighting (Python, JavaScript, Shell, Markdown)
• Configuration file support
• Word wrap

• Multiple buffers/tabs
• Split windows
• Mouse support
• UTF-8 support
• Code folding
• Auto-completion

• Simplicity: Keep codebase small and understandable
• Performance: Fast startup and responsive editing
• Portability: Work across Unix-like systems
• Extensibility: Clean architecture for easy feature addition
• Educational: Readable code serving as a learning resource

• ASCII only (no UTF-8 support yet)
• Tab stops fixed at 8 characters
• No configuration file support
• Single undo level (dirty flag only)
