oha

oha is a terminal-based fullscreen text editor written in C.

Features:

• Fullscreen compositor-style interface using ANSI terminal control
• Left-side file manager toggled with Ctrl+E
• File explorer uses Nerd Font glyphs for folders, files, and parent directory
• Matching SVG icon assets live in assets/icons/
• Arrow-key navigation in the editor and file manager
• Enter opens files or enters folders
• Ctrl+I toggles input mode
• Ctrl+S saves the current file
• Ctrl+Q exits the editor
• Ctrl+F opens search for similar string matches in the current buffer
• Basic syntax highlighting for C-like and shell-style files

Build:

make

Run:

./oha [optional-file]

Install on Linux/macOS:

sudo make install

Windows:

• Build inside a terminal-capable environment such as MSYS2 or MinGW:

make

Notes:

• The program uses standard terminal escape sequences. On Windows, use a terminal that supports ANSI escape codes.
• The terminal UI cannot render SVG directly. The file manager uses Nerd Font glyphs, while the SVG files are kept as dedicated assets.
• For the best icon rendering, use a terminal configured with a Nerd Font. Without one, the icons may appear as missing-character boxes.
• Search uses simple substring matching and jumps to the next match.
