Re: Without breakloop not much of a REPL

[Andy Fingerhut]

There is no reason to merely imagine ... you can do it today.

Here is a transcript of Stuart Halloway's "REPL-Driven Development" talk
with links to sources that he mentions:
https://github.com/matthiasn/talk-transcripts/blob/master/Halloway_Stuart/REPLDrivenDevelopment.md

The part of that talk where he discusses a break facility in the REPL can
be found by searching that transcript for "Joy of Clojure", the book where
one implementation of this is given.

There is a link in the transcript to this repository, which has code you
can copy and paste into your own project, or utility library, etc.

https://github.com/joyofclojure/book-source/blob/master/first-edition/src/joy/breakpoint.clj

The source for the macro named `contextual-eval` is here:
https://github.com/joyofclojure/book-source/blob/master/first-edition/src/joy/macros.clj

 According to this post:
 https://mikelevins.github.io/posts/2020-12-18-repl-driven/

 Breakloop is a true differentiator for "real" REPLs. I can see how
 breakloop really is a game changer.

 Also, there is no breakloop in modern languages such as clojure, which
 is heralded for it's REPL driven development, craftsmans' playground, live
 coding etc...

 Is breakloop gone from modern REPL languages? Maybe it's not a big
 deal? Or is it?

Thanks Brandon, what a productivity booster the breakloop wold be, huh?
Basically would save you time and mental energy every time you sprinkle
your code with print statements now.

Re: Without breakloop not much of a REPL

[Brandon R]

I believe what's described in that post is possible in Clojure, at least to
an extent. I can't remember where I saw it described, but I think it was a
talk by Stuart Halloway. IIRC you can configure Clojure to run
clojure.main/repl when an exception is thrown, this puts you into a new sub
repl with the lexical bindings at that point in execution. You can inspect
things here and I believe change things. I'm not sure about continuing
running with new values, but I'm guessing that's possible too.

Maybe someone in this group can point to a good resource about this, as I
didn't find it in a quick search.

Without breakloop not much of a REPL

[SideStep]

According to this post: 
https://mikelevins.github.io/posts/2020-12-18-repl-driven/

Breakloop is a true differentiator for "real" REPLs. I can see how 
breakloop really is a game changer.

Also, there is no breakloop in modern languages such as clojure, which is 
heralded for it's REPL driven development, craftsmans' playground, live 
coding etc...

Is breakloop gone from modern REPL languages? Maybe it's not a big deal? Or
