emtcl

I assume the plugin is just running Tcl/Tk inside a browser window. I wonder how hard it would be to recreate the same idea using Emscripten drawing to a HTML canvas? People have gotten Tcl to work on Emscripten [0]. I think the big problem is the Tk part. Tk has X11, Win32 and macOS backends, but emscripten supports SDL, for which there is no Tk backend.

Writing such a thing from scratch is pretty impressive - the twelve rules of Tcl syntax are readable (http://www.tcl.tk/man/tcl/TclCmd/Tcl.htm), but it's up to you to figure out the edge cases! As a different take on the same problem, I compiled Tcl to JS with Emscripten - http://aidanhs.github.io/emtcl/. I also wrote a toy DOM library (https://github.com/aidanhs/emtcl/blob/master/opt/dom.c) which plugs into it which you can see demonstrated on the page. One of the nice things about EmTcl is that you can include arbitrary C extensions by also compiling them with Emscripten, which is how the DOM library above works. As a more comprehensive demonstration, have a look at TclDis (http://aidanhs.github.io/tcldis/). That has Tcl, a Tcl C extension I wrote for Tcl <-> Python communication, a Python interpreter and the Python script I wrote for p
