Emscripten port of Public Domain Curses (PDCurses): Terminate your browser!

EMCurses: Terminate your Browser!

EMCurses is a port of PDCurses to HTML/Javascript. It requires Emscripten and can be linked to other applications compiled with Emscripten. It is not merely PDCurses/SDL compiled with Emscripten - which cannot be done easily anyway - but a distinct port that uses the termlib Javascript library for output.

In essence, EMCurses helps you in porting your favourite terminal-based applications to the Web platform; or in designing Web pages in the environment you are accustomed to: the terminal and C programming language.

EMCurses is a work in progress and only a quick hack so far. It's already functional, though.

Installation

cd emscripten/
emmake make

This will produce a libpdcurses.so. When linking it with a Curses application, you should preload termlib.js. For example, the PDCurses rain.c example is compiled/linked as follows:

emcc -I.. -o rain.js rain.c --pre-js termlib.js libpdcurses.so

See e.g. rain.html for an example of embedding an EMCurses application into a Webpage.
