[?] How to enumerate the ClojureScript macros in ClojureScript REPL such as figwheel REPL?

2018-04-05 Thread Philos Kim 
I ran the follwoing code in the figwheel REPL and the result is an empty 
list. 

How can I enumerate the ClojureScript macros?

dev:cljs.user=> (->> (ns-publics 'cljs.core)
 vals
 (filter #(get (meta %) :macro)))
()


Thanks in advance.

Re: D&D + Clojure?

Hey!
I'm a DM, a user of OrcPub2 and a full-time clojure + cljs developer (for 
data science stuff).
I'm definitely interested, let me know!
Also, I play with another colleague, so there's definitely a few more D&D + 
Clojure nerds out there.

I'm interested.

For my own uses I would be curious to see how difficult it would be to
update (degrade? retrograde? :) ) to 3.5/Pathfinder.

Re: [ANN] A couple of libraries for functional reactive web programming - Ulmus & Recurrent

2018-04-05 Thread Robert Levy 
Oh, I misunderstood what jeremykross/recurrent was at first. I thought it
was a cyclejs wrapper, like the various clojurescript wrappers for
reactjs.  It turns out it's a ClojureScript implementation of the approach
that cyclejs implements.

[ANN] dont-give-up: Common Lisp style restarts

2018-04-05 Thread Carlo Zancanaro 

Hey!

I've been playing around a little bit with Common Lisp lately, and 
I've found the interactive restarts to be pretty amazing. So, I've 
implemented something similar to them in Clojure/Cider!


 https://github.com/czan/dont-give-up

It has support for programmatic restarts, but also includes some 
nrepl middleware which will (when paired with the additional elisp 
code) prompt the user for what to do upon failure.


The restarts should interact sensibly with normal JVM exception 
handling. I've put a lot more thought into the exception/restart 
code than I have into the middleware/elisp code, so the cider 
interface is pretty hacky at the moment. If you have experience 
writing nrepl middleware or extending Cider, I'd love your help!


One big problem with this at the moment is that Cider doesn't let 
you do multiple evaluations in parallel, and the interactive 
prompt blocks the thread until you tell it what to do. This means 
you can't evaluate anything else until you have chosen a restart, 
which limits how interactive the system really feels. Fixing this 
has to be done in Cider itself, I believe.


It still needs a polish/improvement to be as good as slime, but 
it's a start!


Carlo

Re: [ANN] A couple of libraries for functional reactive web programming - Ulmus & Recurrent

2018-04-05 Thread Jeremy Kross 
Hey Rob,

That's a great question.  As you can imagine, I like cycle.js a lot, and am 
not a huge fan of React.

The problem with React, imo, isn't (just) that they're addicted to making 
their APIs look like OOP when they're not.  The problem is that they built 
a system on the same [event callback]->[state update] system that's 
inherent to mutational programming.

A Recurrent (or cycle.js) app can be written (conceptually) without state 
altogether.  Components are just functions that take some data, and produce 
other data.  The catch being that the data can change over time, but that's 
actually meaningless from a programming perspective.  You write the code as 
though you were writing pure functions over static data, and (magically 
kinda) it's all wired up and moving at the end.

I think this is a much better model overall, than React.  Components are no 
longer dependent on a giant state ball that can be updated from anywhere 
and cause code to fire off all through the system.  The burden of writing a 
bunch of extraneous constants, actions, reducers, and event handlers is 
lifted.  Functions can't be "connected" to anything.  They get passed some 
data, and return other data, that's all.  

So, I think the cycle.js/fully-reactive model is really brilliant.  That 
may just be the way my brain works, I dunno.  Cycle.js hasn't particularly 
set the world on fire and Recurrent definitely still has some rough edges. 
 But having written a couple of moderately sized apps in Recurrent now, I 
definitely don't want to go back.

Jeremy
