I don't want to be a skeptic, this question is serious, but has anyone produced a large project that used live-editing? I've never seen any example, they are all small code snippets. Any example would be appreciated.

I'm interested in hearing about this too. If it counts, I certainly use R and Python in a live-ish manner but without a lot of the IDE support to truly make it live.

Games/game-engines often can change scripts or even C code out on the fly, so they are at least partially build live. Working in Smalltalk images can be "live-editing", if you run your application at the same time. Both of these examples work on a method-basis: you change the code, trigger a rebuild the method and it is used from then on, not automatically after each change/keypress. There is a bunch of live-coding stuff for creating music, but that often is used with smaller programs and writing the entire program as part of the performance. I think here the more important thing is that it doesn't work on source code that is then parsed and compiled, but directly on a tree structure representing the program. Live-coding is sort of a side effect, because you a) don't have to reparse everything and b) always can have a state that is a valid program.

Live editing works great with React with react-transform-hmr. It's easy to use with most web apps using React.

I use Webpack's Hot Module Replacement [0] along with Redux [1] and React. It's extremely useful for iterating on user interfaces. You just save and your styles and markup update without having to reload. Furthermore, Redux has a devtools library [2] (you can view a gif of it in action in the repo) that lets you do time-travel for debugging purposes. I don't use it much, but it can be occasionally useful. [0] http://webpack.github.io/docs/hot-module-replacement-with-webpack.html http://webpack.github.io/docs/hot-module-replacement-with-we...

I did it for a while ~2006 using ASP.NET, although it wasn't as in-depth as this. It was kind of cool, but after a while it was easier to just use text and view it in a browser. I think it would be more useful to build a tool that helps visualize the overall structure of a program. The usefulness of such a tool would increase as the size of the program increased.

Similar mechanisms at least have been around. Visual studio has had support for "edit and continue" functionality for ages when debugging.

Depends on what qualifies as live-editing, most Lisp software is produced by incrementally adding code into a live image.

I would argue that most browsers qualify in this regard these days (at last partially). Live editing has transformed how I work when creating web apps.
