I just finished watching, and I'm super excited about this idea. There's been a lot of talk in the Clojure community about how to improve documentation, and then Rich comes along and thinks hard about it for a long time and then drops a general purpose data browser. I'm really excited by the possibilities this brings to the table.

> This is design work. Thanks Rich.

Well said! It feels to me that the power of a whole language with simplicity as a core philosophy is now starting to snowball up some really powerful tooling - since small changes can create big improvements.

We've got some new developers at work who are learning Clojure and so I've been rewatching some old Rich Hickey videos (Hammock Driven Development) and it's cool to see the payoff 7 years later of what he was talking about back then.

I think the exciting thing is the datafy protocol, not necessarily this particular viewer. What he demoed seemed much more like a proof-of-concept. Like he said, he's excited to see what the Clojurescript community comes up with, and so am I. I might take a shot at building a browser in Emacs, though that takes away some more dynamic display opportunities.

Wish he had released the tooling. The REBL system looks a bit like the smalltalk virtual machine mixed with elements of Elm's time-traveling debugger. There has been a real need for serious error handling in clojure for a long time (since the stack traces and exceptions are borderline unintelligible). This thing makes it look much more user friendly. They tried to fix the errors with Spec but honestly I don't think t…

The tooling is in datafy and nav, which are in Clojure 1.10. Everything in the UI just flows from those protocols.

Interesting. But one of the points of Clojure is to get away from the object-oriented way so I'm not sure that I'd like Smalltalk.

If I understand it correctly, Smalltalk is really nothing like Java and the mainstream OOP that Clojure is a reaction to.

When clojure meets smalltalk

And I am so stoked for it. Smalltalk did a few things right that have still not been properly copied by other systems, but smalltalk itself was doomed to obscurity the second all the major implementations went for the Common Lisp-style "ship the system as an image" brain damage.

While clojure is far from perfect, it actually has a story for shipping your code, in a form where you don't need to embarrass yourself when your customer gets it, into servers, web pages, desktops and cell phones.

Sometimes it seems as if Cognitect just doesn't want people to use Clojure. It's like they looked at the results from the survey[0], created a tool that appears to address some of the main gripes that people have, and then proceeded to say "screw you" to all of the people that use Clojure commercially and may actually pay for Datomic...

I don't know what world releasing a tool that addresses some of the main gripes that people have is a "screw you", but it doesn't seem like a pleasant one to inhabit. The important bits are in Clojure 1.10.

This is very similar to my own work for the last many years, and I'm sad and delighted he's managed to pull it off in such a clojure-native, slick looking way. Well done. I haven't finished watching the video yet, but it's a little deflating. Still though, if others had been doing this years ago I wouldn't have been scratching that itch.
