This is a proof-of-concept of a SmallTalk like live coding system running in the browser, based on TypeScript. There's no server side component at all (other than delivering static files). It'll let you update your code in a built-in editor and it'll hot-patch the running system so that your code starts working immediately, even if there are objects existing which currently running it.
Watch me talk about it!<iframe width="560" height="315" src="https://www.youtube.com/embed/JDunc6Cr7YQ" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
It's an attempt to replicate the classic SmallTalk/Lisp paradigm which don't distinguish between users and programmers: you can, if you wish, take the lid off the application suite you're currently using and tinker with it, without recompilation, restarts, or even having to save your work.
Currently it's a pile of fairly nasty hacks flying in loose formation, but it does actually work. Mostly.
It's hosted on GitHub.
There's no documentation other than this page.
To use, simply serve this directory in a web server and load the
page. No build stage is needed. The big files are deployed via CDN.
Please note that I developed it on Chrome, and it currently doesn't work on
Firefox; I don't know why. Something to do with scoping and
think. TypeTalk's code generation appears to cause Firefox's debugger to go
nuts which makes it very hard to debug.
