sxceditor2

sxceditor2 is a simple, terminal-based text editor written in C. It provides basic text editing functionality with a vim-like interface.

Features

• Vim-like modal editing (Normal, Insert, and Command modes)
• Basic file operations (open and save)
• Simple navigation using h, j, k, l keys
• Minimal terminal UI
• No dynamic memory allocation (malloc not used)
• No global variables
• Rust-inspired error handling
• Lightweight and portable

Environment

• Operating System: Linux

Dependencies

• None (uses standard C libraries only)

Building

To build sxceditor2, ensure you have a C compiler (like gcc) installed on your system. Then, compile the source code:

gcc -o sxceditor2 sxceditor2.c

Usage

Run the editor:

./sxceditor2

Modes

• Normal mode: Default mode for navigation
• Insert mode: For inserting text
• Command mode: For executing commands

Commands

• :open <filename> - Open a file
• :save <filename> - Save the current file
• :exit or :quit or :q - Exit the editor

Navigation

In normal mode:

• h - Move left
• j - Move down
• k - Move up
• l - Move right
• i - Enter insert mode
• : - Enter command mode

Press Esc to return to normal mode from insert or command mode.

Design Philosophy

SXCEditor is designed with the following principles in mind:

1. Minimal resource usage: No dynamic memory allocation is used, making the editor lightweight and reducing the risk of memory-related errors.
2. No global variables: Improves code organization and reduces potential side effects.
3. Rust-inspired error handling: Provides a more robust and predictable way of handling errors throughout the application.

Limitations

• This is a basic implementation and lacks many features found in full-fledged text editors
• Limited error handling and edge case management
• No syntax highlighting or advanced editing features
• Designed for Linux environments only
