This project by @Glen Chiacchieri deserves its own thread: . Many interesting ideas, including: * Constantly evaluating backward slices of the current line. * Intelligent version of

M-x eval-sexp

that can strip out incomplete blocks. * Persistent interactive settings for every line/scope in a file. (Originally posted at https://futureofcoding.slack.com/archives/C0120A3L30R/p1600695483049500?thread_ts=1600587602.007800)

all my favorite features of this have to with freely defining and passing in stuff from the right pane for variables that aren’t defined yet. you get to save example arguments for your function calls! and use them to figure out states later on in your program!

I forgot to mention that I also really enjoyed the description of the FlowSheets project here. I plan to learn more about it.

This is really cool, thanks for sharing. Trying to figure out if I would use it to teach (given that this was one of the motivations for the work) vs. just using the console + debugger… and I’m not sure. Maybe for students who already had some programming experience? Seems like a lot of the features require some knowledge, although the UI that enables clicking around and editing values / typing in simple expressions would be relatively easy for beginners to use and is really nice… much more immediate than the debugger.
