Tin Isn't Nano

Tin is a portable text editor written in C and inspired by antirez's kilo. It does not depend on any non-standard libraries and uses VT100 escape codes for terminal control rather than curses. It should run on many UNIX-based OSes, including macOS.

Development

In no particular order:

• Read/create files, make changes, and write to disk
• Store file contents in memory using rows containing appendable string buffers
• Write to temporary file first before overwriting target file
• Mash exit command several times to throw out unsaved buffer
• Line numbers
• Find
• Adjust editor size when window is resized
• Status bar with filename, cursor information, and status messages
• Take nonexistent filename argument as new file
• Unicode (UTF8) support
• Keep track of changes per-line to avoid unnecessary updates
• Copy/cut/paste
• Auto-indent if previous line began with tabs
• Search highlighting
• Replace
• Undo/redo
• .tinrc configuration file
• Mouse scroll support
• Mouse cursor click/select support
• Help screen

Usage

Clone the repository and run make all to build tin. If the tin executable is not located somewhere in your $PATH, you'll need to call it with ./tin.

Open a new file by starting the editor with no arguments: tin.

Open a file with tin path/to/file.

Within the editor, use the following commands:

ctrl-x    exit
ctrl-o    save
ctrl-?    help

Caveats

• For now, Tin does not run on Windows because it relies on the ioctl system call. It should work fine in Windows Subsystem for Linux (WSL).
