Vedit - A Modular Terminal Text Editor [WIP]

Vedit is a lightweight, terminal-based text editor written entirely in C. It features a modular architecture, modal editing, and directory navigation, all powered by VT100 escape sequences without any external UI libraries.

New Features

• Interactive Directory Exploration:
  • Open any directory with vedit <path> (e.g., vedit .).
  • Navigate folders and open files directly using Enter.
  • Supports parent directory (..) navigation.
• Improved Buffer Management:
  • Multi-Step Undo: Press u in Normal Mode to revert up to 50 previous changes.
  • Line Numbers: Highlighting the current line for better focus.
  • Modular Codebase: Split into logical components (rows, editing, undo, explorer, etc.) for easier maintenance.
• Enhanced Editing:
  • x: Delete character under the cursor.
  • dd: Delete current line.
  • Full support for Home, End, PageUp, and PageDown.
• Global Installation:
  • Nix Support: Install globally using nix profile install ..
  • Manual Option: Use bash install.sh to install to /usr/local/bin.

Modal Editing

• NORMAL: Navigation (h, j, k, l), undo (u), and character deletion (x).
• INSERT: Standard text entry (i to enter).
• COMMAND: File operations and help (: to enter).
• HELP: Interactive help screen (:help).
