Earlier in the year I had somewhat the opposite problem. I'm very fluent
with Windows 7 command line use, so I use the free TCC/LE cmd replacement
[1]. However, lein.bat v2.3.4 broke when used from TCC/LE [2][3].

As it is presumably more likely that advanced Windows users would be
interested in trying something like Clojure, they also might know it's
better to use TCC/LE than the built-in cmd. As such any incompatibility
between lein.bat and TCC/LE should be noted somewhere along with the
probable fix mentioned in [3].

I don't know if this is no longer an issue with lein.bat because I've since
switched over to trying F# and haven't been playing with Clojure (or
leiningen or Emacs/Cider or IntelliJ/Cursive or Light Table).

Not to be ungrateful, but it would be much better if all videos came with
"table of contents" that had links to the start times of each "Chapter",
"Section", "SubSection" (aka Slide) of the talk. YouTube supports this
automatically by converting text in the form of hh:mm:ss to links to that
point in the video. BTW this works even in comments so anyone can add TOCs,
but obviously it's better if the TOC is in the description.

Re: Clojure for Desktop UI Design Application

Since I'm still investigating Clojure, my first instinct when writing a
desktop GUI --- similar to what Timothy Baldridge mentions --- is to use C#
+ WPF. In particular I really like the Model-View-ViewModel architecture
enabled by the fancy data binding that XAML/WPF can do. And the relatively
new Assisticant [1] [2] seems to make that even easier (though I've haven't
actually used it yet).

Given that I'm more comfortable with .NET... for functional programming
I've started to use F# for "real work" (as opposed to toy apps/solving
koans while learning Clojure). While you can write WPF apps with F# there
is still some work to do. FsXaml [3] [4] is trying to address this need.
And while I'm still learning, it seems like F# can do React-like
"Functional Reactive Programming" [5]. Of course ClojureCLR [6] is also an
alternative for .NET-centric types but I only looked at it briefly.

I spent some time trying to grok LightTable, but the
Clojure/ClojureScript/Javascript/leiningen/Google Closure
compiler/JVM/node-webkit combo caused me to give up for now. It didn't help
that Windows support tends to be an afterthought. BTW LightTable is
seriously considering jettisoning node-webkit and switching to the github
Atom shell instead [7].

varying realization of a lazy-seq of strings?

[TP]

Hi,

I am writing to ask if a behavior that I find strange is a bug or 
intended? In the latter case I would like to learn why is it so.


In the REPL I see the following, that I think is OK:

user=> (def test-data (lazy-seq [(str ["ZiZi"])]))
#'user/test-data
user=> test-data
("[\"ZiZi\"]")

However, if I call "print" in between the previous 2 lines, test-data 
becomes different at the end:


user=> (def test-data (lazy-seq [(str ["ZiZi"])]))
#'user/test-data
user=> (print test-data)
([ZiZi])nil
user=> test-data
("[ZiZi]")

I found that the "binding" of  *print-readably* in the code of "print" 
makes the difference. If it is nil (as in print), I get the faulty 
value. If it is true, then I get the right (inner-quoted) value.


I learned (from e.g. Stuart Halloway at 
http://grokbase.com/t/gg/clojure/149d3t0gwh/schrodingers-cat-in-clojure) 
that mixing lazy evaluation and I/O can lead to confusing situations and 
that is normal. However here I feel that I get different values of the 
same expression depending on which action triggers its realization: if 
it is (e.g.) print, then it is realized in a faulty way: "[ZiZi]" is not 
correct, since ZiZi should be quoted inside the string by \"-s. (I know 
the missing inner quotes are not just a REPL printing issue as I 
distilled this question after spending hours to hunt down strange error 
messages in a real commercial program.) In other words it seems to me 
that having *print-readably* nil, makes the realization of this lazy-seq 
failing.


I also see that the problem disappears if I do not use lazy-seq (or 
map...) or if I code the string directly (without "str"):


user=> (def test-data (lazy-seq ["[\"ZiZi\"]"]))
#'user/test-data
user=> (print test-data)
(["ZiZi"])nil
user=> test-data
("[\"ZiZi\"]")

and

user=> (def test-data [(str ["ZiZi"])])
#'user/test-data
user=> (print test-data)
[["ZiZi"]]nil
user=> test-data
["[\"ZiZi\"]"]

I verified this behavior both in (pure, i.e. not Lein) REPL of Clojure 
1.8 and 1.9.0-alpha20.


Please help me understanding what's going on here.

Thanks,P

As a first step I would recommend this tutorial:

your efforts.

After working through the introduction

about to start the language guide

was just wondering if there is a recommended order in which to
work through the guide (or should I do a tutorial and then use the

functions, if so, what comes after that as I am a bit overwhelmed
by all the things I don't know :)
