Kilo
A text editor in less than 1000 LOC with syntax highlight and search
...It was created by Salvatore Sanfilippo (antirez, also known for Redis) as an exercise in writing a small, self-contained editor that others can study and extend. Despite its tiny size, Kilo supports core editor features like opening and saving files, incremental search, and basic syntax highlighting. It deliberately avoids external dependencies, not even using curses; instead it talks directly to the terminal using VT100 escape sequences, making it portable to most Unix-like systems with a compatible terminal. Because the codebase is compact and well-structured, it has become a popular teaching and learning resource, inspiring tutorials such as “Build Your Own Text Editor” that walk through implementing Kilo step by step.
