bouncer is a validation DSL for Clojure apps
Github: https://github.com/leonardoborges/bouncer
Clojars: https://clojars.org/bouncer
New in version 0.2.3-beta1:
- Validator sets can now be used at the top level call to validate and
valid?
- Added tests and a doc section around validation pipelini
Oops, there's an open case to bring lein-cljsbuild's default compiler
version up to r1586: https://github.com/emezeske/lein-cljsbuild/issues/186.
I will try to get to that soon.
In the meantime, you should be able to add [org.clojure/clojurescript

Clojure's sequences are lazy - but is there anything that guarantees *how* lazy
they are?
To give a concrete example - given an infinite lazy sequence of promises:
(def promises (repeatedly promise))
If, in one thread I do:
(doseq [p (map deref promises)] (println p))

I'm not sure if lein-cljsbuild uses the latest release of ClojureScript -
Evan would know. In general I think it's probably best to just specify the
version of ClojureScript you want to use yourself to avoid any issues.

That's likely though pldb is so small I don't really think it would require
much in the way of changes.

I have been in touch with the writer of the modern-cljs tutorial, and he
thinks that
a library include is missing that used to be a problem, but was fixed. It
looks like
the problem is back.
You can follow the issue and discussion here:

Thank you! I implemented your suggestion of breaking up the Java code.

I just tried loading a real data file (30M tsv) for the first time (I mean,
instead of just unit tests on my loading program with tiny files), which
resulted in this output:
Exception in thread "main" clojure.lang.ExceptionInfo: :peer/timeout

This the syntax for map destructuring. Works on function argument vector
and let bindings.
You'll find multiple online resources that explain this clearly.

You could also consider visually breaking up Java code that is across
multiple files. You've got "// Contents of:" comments, but a break in the
grey background would also be helpful.
Nice post. The world needs more people willing to explain basic concepts in
a clear, un-patronising way.
Cheers,
Could it be that you're using lein1 instead of lein2? Is lein1 still
actively maintained? In any case I suggest you upgrade to lein2...

The error looks like its coming from java rather than leinengen.
And the error might be due to quil loading some dll in the jre which is

As a temporary hack, perhaps you could implement a deftype
ReduceToTransient wrapper that implements CollReduce by calling reduce on
the parameter, and then calling persistent! on the return value of reduce.
You'd also need to implement CollFold so that the partitioning function

You could use the proposed change (second link) and use a patched clojure
in your application.

It doesn't decomplect anything, in fact. It just uses a *different* rule

It is fair to say that, if applied uncritically, for example by beginners
who haven't yet gotten the hang of it, thrushes really can create a mess.
For example:

This really does break the "application chaining" mental shortcut and
forces you to mentally unapply

Source code is badly mangled and some bulleted lists are flowed into a
