This looks really nice. venantius: you should make a fancy demo with http://showterm.io

Although I guess its not that interactive. There should be more of these instead of gif demos for tty programs though.


Huh, that's pretty cool. I've been looking for a tool to do something like this for a while - I'll give it a shot on my next project.


https://asciinema.org/ also does the same thing :) They're really nifty to use


Better stack traces is huge. One of the biggest pain points in Clojure development today.


With Ultra and Mezzano (Common Lisp OS) on HN today, you can feel the Lisp joy :-)

I read the blog article on Ultra several days ago but I just tried it this afternoon. Seems really nice. I would like to play with a new theme to change the screen colors a bit (I assume pull requests are welcome).

Thanks for the good work.


Yep, pull requests for colorschemes in particular would be fantastic! It'd be great to flesh out a set of colorschemes to cover the major ones in usage today.


Looks great! I've recently been trimming down on the number of Lein plugins I have installed, but I think this one is deserving of a line in my `profiles.clj`...now how about Boot? ;-)


jballanc! Glad to have your inclusion :) Are you using Boot these days?


We've really just started exploring Boot, but given how much better it deals with ClojureScript (especially in the context of http://cljsjs.github.io), we're taking it rather seriously. For my personal side-projects, I've just started a new one with Boot. My experience so far is that it's definitely not as "full-featured" an experience as Lein, but it does feel more "composable" and, dare I say it, more "like Clojure".


That's good to hear, because to me Lein feels like, well, Maven.


I also think spyscope would be a good inclusion FWIW.


I've been using this for a week or so now. I wish I could figure out how to get colorized output in my SublimeREPL, but other than that, I can't say how much better this makes my clojure dev time.


The first example in https://raw.githubusercontent.com/venantius/ultra/gh-pages/i... is a bit annoying though. The key :gamma is the same and the nice diff you get on maps aren't applied to the thing inside :gamma that is actually differing.

That being said, this seems like a HUGE improvement for every day clojure development.


Looks great! I'll be using this from now on.


This looks really good, thanks for posting! I will definitely try this out tomorrow :)


Clojure noob here - could this work with Cursive?


I'm not sure how this will work with Cursive, but Cursive already provides nearly all of this functionality out of the box anyway. Cursive has colourised REPL output for ages, the test results have a graphical diff, and its Java navigation is way ahead of anything else. Cursive will do some stacktrace prettification if you have clj-stacktrace or Aviso pretty installed, but it doesn't automatically prettify all of them - I'll be adding that soon.


Does this play well with CIDER?
