Open Source C Command Line Tools

ttyd is a command-line tool that shares a terminal session through a web browser. It runs on Unix-like systems and Windows, making it useful for remote administration, browser-based development environments, demos, lab machines, and containerized tools. The project is built on libuv and WebGL2 to provide a responsive browser terminal experience. It can run custom commands with options, support authentication, and expose shell access over HTTP or HTTPS. ttyd also includes practical terminal features such as CJK and IME input, ZMODEM and trzsz file transfer, Sixel image output, SSL support, and reverse proxy compatibility. It is best suited for users who want a lightweight way to access command-line programs from any modern browser.

Ansi2txt converts a stream of vt100 (ansi) codes on the stdin into readable text on the stdout. It can also output html that looks quite a lot like your terminal did. Works fine with ncurses output. Compile the C source into the command line tool.

A library facilitating complex TUIs on modern terminal emulators, supporting vivid colors, multimedia, threads, and Unicode to the maximum degree possible. Things can be done with Notcurses that simply can't be done with NCURSES. It is furthermore fast as shit. What it is not: a source-compatible X/Open Curses implementation, nor a replacement for NCURSES on existing systems. Notcurses abandons the X/Open Curses API bundled as part of the Single UNIX Specification. For some necessary background, consult Thomas E. Dickey's superb and authoritative NCURSES FAQ. As such, Notcurses is not a drop-in Curses replacement. Wherever possible, Notcurses makes use of the Terminfo library shipped with NCURSES, benefiting greatly from its portability and thoroughness. Notcurses opens up advanced functionality for the interactive user on workstations, phones, laptops, and tablets, possibly at the expense of e.g. some industrial and retail terminals.
